Liu P, Song Y, Wei J, Mao W, Ju J, Zheng S, Zhao H. Synergistic Effects of Earthworms and Plants on Chromium Removal from Acidic and Alkaline Soils: Biological Responses and Implications. BIOLOGY 2023; 12:831. [PMID: 37372116 DOI: 10.3390/biology12060831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 06/06/2023] [Accepted: 06/07/2023] [Indexed: 06/29/2023]
Abstract
Soil heavy metal pollution has become one of the major environmental issues of global concern and solving this problem is a major scientific and technological need for today's socio-economic development. Environmentally friendly bioremediation methods are currently the most commonly used for soil heavy metal pollution remediation. Via controlled experiments, the removal characteristics of chromium from contaminated soil were studied using earthworms (Eisenia fetida and Pheretima guillelmi) and plants (ryegrass and maize) at different chromium concentrations (15 mg/kg and 50 mg/kg) in acidic and alkaline soils. The effects of chromium contamination on biomass, chromium bioaccumulation, and earthworm gut microbial communities were also analyzed. The results showed that E. fetida had a relatively stronger ability to remove chromium from acidic and alkaline soil than P. guillelmi, and ryegrass had a significantly better ability to remove chromium from acidic and alkaline soil than maize. The combined use of E. fetida and ryegrass showed the best effect of removing chromium from contaminated soils, wih the highest removal rate (63.23%) in acidic soil at low Cr concentrations. After soil ingestion by earthworms, the content of stable chromium (residual and oxidizable forms) in the soil decreased significantly, while the content of active chromium (acid-extractable and reducible forms) increased significantly, thus promoting the enrichment of chromium in plants. The diversity in gut bacterial communities in earthworms decreased significantly following the ingestion of chromium-polluted soil, and their composition differences were significantly correlated with soil acidity and alkalinity. Bacillales, Chryseobacterium, and Citrobacter may have strong abilities to resist chromium and enhance chromium activity in acidic and alkaline soils. There was also a significant correlation between changes in enzyme activity in earthworms and their gut bacterial communities. The bacterial communities, including Pseudomonas and Verminephrobacter, were closely related to the bioavailability of chromium in soil and the degree of chromium stress in earthworms. This study provides insights into the differences in bioremediation for chromium-contaminated soils with different properties and its biological responses.

Insights into the spatiotemporal differences in tailings seepage pollution by assessing the diversity and metabolic functions of the soil microbial community. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 306:119408. [PMID: 35523382 DOI: 10.1016/j.envpol.2022.119408] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 03/29/2022] [Accepted: 04/30/2022] [Indexed: 06/14/2023]
Abstract
The formation of tailings ponds depends on the long-term accumulation of tailing and high terrain. Its seepage pollution characteristics may have gradient variations on spatiotemporal scales. Used three nearby metal tailings ponds with different service times, we aimed to reveal seepage pollution trends on spatiotemporal scales and the response of soil microbial community. The results showed that the degree of seepage pollution was negatively correlated with the distance from the tailings pond on the spatial scale, while the seepage pollution showed higher levels in tailings ponds with longer service times on the temporal scale (RI = 248.04-2109.85). The pollution effect of seepage persisted after the tailings pond was discontinued (RI = 226.72). Soil microbial diversity increased with spatial scale expansion. The proportion of Actinomyces gradually increased and Proteobacteria decreased. Cr (r = 0.21) and Fe (r = 0.22) contributed more to the microbial community changes. Functional predictions showed that pathways related to signal transduction and energy metabolism were more abundant in the tailings pond. In contaminated areas, the proportion of nitrate respiration and cellulolysis functional communities had decreased, and some potentially pathogenic human taxa had accumulated. These results emphasized that there was pollution accumulation on temporal scale and pollution dispersion on spatial scale around tailings ponds, and the response of the microbial community further illustrated these trends.

The Effect of Soil Amendments on Trace Elements’ Bioavailability and Toxicity to Earthworms in Contaminated Soils. APPLIED SCIENCES-BASEL 2022.

Abstract
The aim of this study was to assess the impact of soil amendments, characterized by different sorption properties, on the effectiveness of trace elements’ (Cu, Zn, Pb, Cd, Ni, and Cr) stabilization and bioavailability to earthworms. The study was conducted as a microcosm experiment using soil derived from a heavily contaminated post-industrial area. The Eisenia veneta earthworm was cultured for 4 weeks in soils amended with materials characterized by different properties, origins, and potential effects on limiting the availability of metals in soils: two type of compost (Zabrze compost-ZC; GWDA compost-GC), two types of biosolid (Bełchatów biosolids-BB, Grabów biosolids-GB), calcium phosphate (CP), iron oxide (IO), bentonite (BE), rock waste (RW), and limestone (CC). After the incubation, the biomass and survival numbers of the earthworm species decreased significantly (p < 0.05). The accumulation of metals in the earthworm tissues expressed by the bioaccumulation factor value (BSAF) were dependent on the type of amendment applied to the soil. The highest decrease in the earthworms’ weight and survival rate was caused by compost (72%) and bentonite (33%), while the lowest was caused by the rock waste (10%) and iron oxide (11%). The biosolids exhibited the greatest toxicity, causing the mortality of all the earthworms. The accumulation of metals in earthworm tissues and the BSAF value were dependent on the type of amendment applied to the soil. The BSAF for the contaminated soil by Cd decreased to the greatest extent after the addition of ZC (by 57%), GC (55%), CP (41%), and IO (37%). A similarly positive effect was noted for Pb after IO addition (45% decrease). The Zn, Cr, and Ni concentration in earthworms, contrary to other elements, increased, regardless of the amendment. The results showed that the applied soil amendments were characterized by varying potential for the reduction in the metal bioavailability in the soil, depending on their composition and physicochemical properties. Moreover, earthworms may exhibit a diversified response to soil amendments as a result of the impact of amendment on the metal forms in soils and their direct impact on organisms. Generally, the Cd was easily transferred from the soil into and accumulated in the earthworm tissues. Our study confirms that this element creates the highest risk for the trophic chain in soils affected by the Zn and Pb smelting industry. Moreover, greater Zn supply reduces the accumulation of Cd in animal bodies. This study provides valuable practical knowledge on the short-term biological effects of a range of soil amendments in metal-contaminated soils.

Abstract
Global concerns towards potentially toxic elements (PTEs) are steadily increasing due to the significant threats that PTEs pose to human health and environmental quality. This calls for immediate, effective and efficient remediation solutions. Earthworms, the 'ecosystem engineers', can modify and improve soil health and enhance plant productivity. Recently, considerable attention has been paid to the potential of earthworms, alone or combined with other soil organisms and/or soil amendments, to remediate PTEs contaminated soils. However, the use of earthworms in the remediation of PTEs contaminated soil (i.e., vermiremediation) has not been thoroughly reviewed to date. Therefore, this review discusses and provides comprehensive insights into the suitability of earthworms as potential candidates for bioremediation of PTEs contaminated soils and mitigating environmental and human health risks. Specifically, we reviewed and discussed: i) the occurrence and abundance of earthworms in PTEs contaminated soils; ii) the influence of PTEs on earthworm communities in contaminated soils; iii) factors affecting earthworm PTEs accumulation and elimination, and iv) the dynamics and fate of PTEs in earthworm amended soils. The technical feasibility, knowledge gaps, and practical challenges have been worked out and critically discussed. Therefore, this review could provide a reference and guidance for bio-restoration of PTEs contaminated soils and shall also help developing innovative and applicable solutions for controlling PTEs bioavailability for the remediation of contaminated soils and the mitigation of the environment and human risks.

Abstract
Mining and processing metalliferous ores can degrade the environment well beyond the footprint of the mine, particularly where on-site containment and post-mining remediation has been insufficient to prevent releases of solid and aqueous mine wastes. In this study, we investigated the potential of sediment and water chemistry coupled with environmental (e)DNA metabarcoding to evaluate discrete and cumulative ecological impacts of two legacy base metal (copper (Cu), zinc (Zn), lead (Pb)) mines (Peelwood and Cordillera) which discharge metals via ephemeral tributaries into perennial Peelwood Creek. Although the two mine streams exceeded Australian guidelines for sediment and freshwater quality for Cu, Zn and Pb, Peelwood Creek had relatively low sediment and water metal concentrations, suggesting a low potential for environmental toxicity. Although sediment and water chemistry defined the extent of biological impacts, metabarcoding showed that Peelwood and Cordillera mines had discrete impacts and Peelwood mine was the main source of contamination of Peelwood Creek. Metabarcoding showed that prokaryotes can be good indicators of metal contamination whereas eukaryotes did not reflect contamination impacts in Peelwood Creek. Metabarcoding results showed that benthic communities downstream of Cordillera mine were less impacted than those below Peelwood mine, suggesting that Peelwood mine should be considered for further remediation.

Abstract
Heavy metal pollution is posing a severe health risk on living organisms. Therefore, significant research efforts are focused on their detection. Here, we developed a sensing platform sensor for the selective detection of lead(II) acetate. The sensor is based on self-assembled polyethyleneimine-functionalized carbon nanotubes (PEI-CNTs) and graphene oxide films deposited onto gold interdigitated electrodes. The graphene-based nanostructure showed a resistive behavior, and the fabricated layer-by-layer film was used to detect Pb(II) acetate in an aqueous solution by comparison of three electrochemical methods: impedance spectroscopy, amperometry, and potentiometry stripping analysis. The results obtained from different methods show that the detection limit was down to 36 pmol/L and the sensitivity up to 4.3 μAL/μmol, with excellent repeatability. The detection mechanism was associated with the high affinity of heavy metal ions with the functional groups present in the PEI-CNTs and GO, allowing high performance and sensitivity. The achieved results are important for the research toward integrated monitoring and sensing platforms for Pb(II) contamination in drinking water.

The dual beneficial effects of vermiremediation: Reducing soil bioavailability of cadmium (Cd) and improving soil fertility by earthworm (Eisenia fetida) modified by seasonality. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 755:142631.

Abstract
This study aimed to assess earthworm's capability of reducing the bioavailability of cadmium (Cd) in soil and increasing soil fertility with the modification of seasonal variations of ambient temperatures on the efficacy of vermiremediation. Earthworms were exposed in soil fortified with 0, 5, 10, and 20 mg Cd kg-1, for 7, 14 and 21 days in winter and spring. The bioavailability of Cd in soil, which is represented in the form of diethylenetriaminepentaacetic acid-extractable fraction (DTPA-Cd), were significantly reduced, ranging from 7.9 to 18.3% in winter and 8.8 to 20.8% in spring. Meanwhile, we found earthworm activities could significantly improve the soil fertility as the results of increasing the availability of nitrogen, phosphorous, and potassium in soil, a prominent advantage of vermiremediation in heavy metal-contaminated soil. Although seasonality could increase Cd toxicity in earthworms, higher ambient temperature in spring season also promoted the reduction of Cd bioavailability and the increase of soil fertility, due to significant increase of microbial populations. In conclusion, we reported the dual beneficial effects of vermiremediation in reducing bioavailability of Cd in soil and simultaneously improving soil fertility in which both outcomes were modified by seasonality.

Abstract
The accumulation of Ag2S in agricultural soil via application of Ag-containing sludge potentially affects the functioning of soil microorganisms and earthworms (EWs) due to the strong antimicrobial properties of Ag. This study examined the effects of Ag2S nanoparticles (Ag2S-NPs) on the EW-mediated (Eisenia fetida and Pontoscolex corethrurus) soil N cycle. We used 16S rRNA gene-based sequencing and quantitative polymerase chain reaction to examine the bacterial community and nitrification/denitrification-related gene abundance. The presence of either EWs or Ag significantly increased denitrification and N2O emissions. However, the addition of Ag2S to EW-inhabited soil reduced N2O emissions by 14-33%. Furthermore, Ag2S caused a low-dose stimulation but a high-dose inhibition to N2O flux from the EW gut itself. Accordingly, an increase in Ag in the EW gut caused a decrease in the relative abundance of denitrifiers in both the soil and the gut, especially for the dominant genus Bacillus. Ag2S also decreased the copy numbers of nitrification gene (nxrB) and denitrification genes (napA, nirS, and nosZ) in EW gut, leading to the observed decrease in N2O emissions. Collectively, applying Ag2S-containing sludge disturbs the denitrification function of the EW gut microbiota and the cycling of N in soil-based systems.

Assessment of earthworm activity on Cu, Cd, Pb and Zn bioavailability in contaminated soils using biota to soil accumulation factor and DTPA extraction. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 195:110513. [PMID: 32213370 DOI: 10.1016/j.ecoenv.2020.110513] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 03/16/2020] [Accepted: 03/17/2020] [Indexed: 06/10/2023]
Abstract
The study aims to investigate effect of earthworm activity on metal bioavailability in soils using their BSAF-metals. Based on a microcosmic laboratory experiment, epigeic species Amynthas corticis (A. corticis) and endogeic species Amynthas robustus (A. robustus) were cultured in two types of soils contaminated by Cd, Zn, Pb and Cu for 120 days. Earthworm characteristics (i.e. numbers, biomass and BSAF), soil properties (i.e. pH, organic C and N contents along with their components such as mineralization and microbial masses) and DTPA extracted metals in soil were determined. After the incubation, the biomass and survival numbers of both earthworm species decreased significantly (P < 0.05). The accumulation of Cd, Zn and Pb in earthworm tissues and BSAF-metals were earthworm species dependent. According to two-way ANOVA, BSAF-Pb clearly showed the effect of different species of earthworms while BSAF-Cu indicated an interactive effect of earthworms and soil type. Earthworms changed soil properties significantly, especially for mineralized C (Cmin), dissolved N (Ndis) and pH (P < 0.05). Earthworm activity increase DTPA extracted Zn and Cu, and the effect of A. robustus were stronger than for A. corticis. Redundancy analysis (RDA) showed that BSAF-Cu and BSAF-Pb contributed for respectively 51.9% and 51.7% of soil properties and DTPA metal changes, indicating that the effects of BSAF-Cu and BSAF-Pb on soil properties and on metal bioavailability in soil were similar. BSAF-Cu, indicating the interactive effect of earthworms and soil, accounted for 38.5% and 45.1% of soil properties and soil metal bioavailability changes. BSAF-Pb, representing the effect of earthworm species, accounted for 13.3% and 6.6% of soil property and soil metal bioavailability variations. Stepwise regression indicated that earthworm might change soil properties through their activities and interactions with soil, and hence increase heavy metal bioavailability. It suggested that BSAF is an important indicator for evaluating the effect of earthworm activity on soil metal bioavailability and designing remediation strategies.

Raiesi F, Motaghian HR, Nazarizadeh M. The sublethal lead (Pb) toxicity to the earthworm Eisenia fetida (Annelida, Oligochaeta) as affected by NaCl salinity and manure addition in a calcareous clay loam soil during an indoor mesocosm experiment. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 190:110083. [PMID: 31864123 DOI: 10.1016/j.ecoenv.2019.110083] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2019] [Revised: 12/04/2019] [Accepted: 12/10/2019] [Indexed: 06/10/2023]
Abstract
The combined effects of salinity and organic amendments on lead (Pb) toxicity to earthworms as important components of soil invertebrates are still largely unknown. A mesocosm experiment was conducted to examine how the combined use of NaCl salinity and cow manure would affect the sublethal Pb toxicity to chronically exposed Eisenia fetida in natural soil. The response of life-cycle parameters of this earthworm species and biological properties to NaCl-induced salinity (0, 4 and 8 dS m-1) was determined in a Pb-contaminated clay loam soil amended or unamended with fresh cow manure. The NaCl salt and cow manure (4%, w/w) were added to the soil and the mixtures were incubated for 90 days under greenhouse conditions. The results showed that NaCl salinity increased soil Pb availability and toxicity, increased earthworm Pb concentration and uptake, and decreased earthworm survivorship, population (adults and juveniles), reproduction, wet weight, cocoon production, and cast activity. The detrimental effects of NaCl salinity on earthworms and biological properties were greater at high than low salinity levels. Addition of cow manure lowered the NaCl-induced Pb toxicity to earthworms at all salinity levels, suggesting the harmful effect of salinity-induced Pb toxicity was reduced due to the decreased Pb availability following manure application. This study demonstrated that soil salinity and animal manures can have a great impact on the life-cycle endpoints and activity of E. fetida, which requires attention when using saline waters for irrigation and organic amendments for soil amelioration in Pb-contaminated environments. It is concluded that (i) the multiple stresses induced by salinity and Pb mixtures may negatively affect earthworms and (ii) organic amendment application has a high potential for lowering the stronger negative effect of salinity in Pb-polluted environments and for improving earthworm population, reproduction and activity.

Lee WC, Lee SW, Jeon JH, Jung H, Kim SO. A novel method for real-time monitoring of soil ecological toxicity - Detection of earthworm motion using a vibration sensor. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2019; 185:109677. [PMID: 31563747 DOI: 10.1016/j.ecoenv.2019.109677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 09/09/2019] [Accepted: 09/11/2019] [Indexed: 06/10/2023]
Abstract
The aim of this study was to develop a new method, using a vibration sensor, to address the drawbacks of preexisting methods for monitoring soil ecological toxicity. A novel method was designed by inspiration from seismometers, which record signals originating from the ground motion caused by earthquake events. Similarly, the newly developed method using a vibration sensor detects the signals generated by earthworm activity, which reflects the soil ecological toxicity. To establish the new method, a stepwise approach was adopted: (1) the effects of operational conditions on the overall performance of the system were evaluated, and (2) the feasibility of the method was tested by an application study. A number of crucial factors influencing the overall performance of the method were evaluated. These were categorized based on three features: soil, tested organism, and instrumentation. The soil properties evaluated included soil type (artificial and natural), moisture content, and bulk density. In terms of the organism, the effect of the number of earthworms was investigated. Finally, with regard to instrumentation, appropriate soil chamber specifications and monitoring duration were identified. The most effective conditions for each factor were determined based on a comparative evaluation of changes in the activity levels and body weights of the earthworms. After the first step of the study, an application study was carried out to demonstrate the feasibility of the proposed method. Zinc (Zn)-contaminated soils were tested under the most efficient operational conditions identified in the preceding study. The results of the study confirm that the method is applicable to natural soils, and the best performance was achieved under soil conditions of 50-60% maximum water holding capacity and 0.95 g/cm3 bulk density. Furthermore, the optimal number of earthworms was found to be five, which corresponds 19.84 g soil per earthworm. With respect to the instrumental conditions, the most efficient specification was a cylindrical soil chamber with a diameter of 94 mm and height of 54 mm. Additionally, the most relevant monitoring duration was found to be 7 days. The results indicate that the method can shorten the testing period, reduce the soil amount and earthworm number required, and facilitate the real-time monitoring of mortality. Based on the results of the application study, we validated the proposed vibration sensor-based method for characterizing earthworm behavior in terms of its feasibility for monitoring the ecological toxicity of soil. The results indicate that dermal contact and feeding activity of earthworms decreased significantly with increasing Zn concentrations in the soil. The EC50 value of Zn calculated based on the earthworm behavior was 340.97 mg/kg. Based on the results, it is concluded that the proposed method cannot only overcome the shortcomings of traditional test methods using earthworms, but also enable real-time ecotoxicity in soil environments.

Abstract
The risk element accumulation ability of two groups of epigeic species, insects from families Coleoptera and Hymenoptera (namely Formicidae), was determined and related to soil risk element content and bioaccessibility. The study was conducted in the district of Příbram, Czech Republic, which was characterised by extremely high aged pollution in the soils, including risk elements, especially As, Pb, Zn and Cd, due to the former mining and smelting activity. Four sampling sites differing in their pseudo-total risk element contents were selected and composite samples of individuals representing either Coleoptera or Formicidae were sampled at the individual sampling points. The results indicate the ability of Coleoptera and Formicidae organisms to accumulate risk elements, especially at the location with extremely high soil risk element content. In soil containing up to 841 mg As kg-1, 84.6 mg Cd kg-1, 4250 mg Pb kg-1 and 8542 mg Zn kg-1, contents in insect bodies reached 239 mg As kg-1 As, 24.2 mg Cd kg-1, 70.4 mg Pb kg-1 and 335 mg Zn kg-1 in beetles and up to 20.9 mg As kg-1, 29.9 mg Cd kg-1, 111 mg Pb kg-1 and 657 mg Zn kg-1 in ants. Therefore, bioaccumulation factors (BAFs) varied between 0.02 and 0.55. Increasing Cd content in Coleoptera bodies with increasing soil pseudo-total element content was observed only among the investigated elements. However, the results indicate increasing BAF values with decreasing soil element levels, especially for Cd, Pb and Zn, indicating limited uptake of elements by the organisms living in contact with extremely contaminated soil.

Abstract
The aim of this study was to determine ecotoxicological parameters for biomonitoring of environmental risk of native soils from a ceramic industrial area that had been contaminated with cadmium (Cd) and chromium (Cr) by using the earthworm, Eisenia fetida. Initially, lab tests were conducted to compare earthworm (Eisenia fetida) growth, survival, morphology, behavior, and reproduction rates following exposure to six concentrations of contaminated soil at 0%, 6.25%, 12.5%, 25%, 50%, or 100% mixed in artificial soil and cow dung following a 28-d incubation period. The second experiment consisted of utilizing Eisenia fetida in a predetermined lowest observed effect concentration to measure heavy metals bioaccumulation from superficial soil collected from a ceramic industrial area following a 56-d exposure. Data demonstrated that in the lab earthworms maintained at 6.25% of contaminated soil, exhibited significant increase in mean weight, bioaccumulation of Cd and Cr associated with a significant decrease in the amount of Cd and Cr in the soil. At field testing, similar results that were observed as in the lab as evidenced by rise in mean weight, higher levels of Cd and Cr in the earthworm tissue accompanied by significant fall in soil levels of Cd and Cr. In conclusion, at tested relevant environmental concentrations, the use of Eisenia fetida for assessing ecotoxicological risk arising from contaminated soil due to ceramic industrial pollutant emissions was found to be an effective tool for biomonitoring program.
