Differential capacity of phragmites ecotypes in remediation of inorganic contaminants in coastal ecosystems: Implications for climate change. ENVIRONMENTAL RESEARCH 2024; 247:118127. [PMID: 38220075 DOI: 10.1016/j.envres.2024.118127] [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: 07/15/2023] [Revised: 12/19/2023] [Accepted: 01/05/2024] [Indexed: 01/16/2024]
Abstract
Remediating inorganic pollutants is an important part of protecting coastal ecosystems, which are especially at risk from the effects of climate change. Different Phragmites karka (Retz) Trin. ex Steud ecotypes were gathered from a variety of environments, and their abilities to remove inorganic contaminants from coastal wetlands were assessed. The goal is to learn how these ecotypes process innovation might help reduce the negative impacts of climate change on coastal environments. The Phragmites karka ecotype E1, found in a coastal environment in Ichkera that was impacted by residential wastewater, has higher biomass production and photosynthetic pigment content than the Phragmites karka ecotypes E2 (Kalsh) and E3 (Gatwala). Osmoprotectant accumulation was similar across ecotypes, suggesting that all were able to successfully adapt to polluted marine environments. The levels of both total soluble sugars and proteins were highest in E2. The amount of glycine betaine (GB) rose across the board, with the highest levels being found in the E3 ecotype. The study also demonstrated that differing coastal habitats significantly influenced the antioxidant activity of all ecotypes, with E1 displaying the lowest superoxide dismutase (SOD) activity, while E2 exhibited the lowest peroxidase (POD) and catalase (CAT) activities. Significant morphological changes were evident in E3, such as an expansion of the phloem, vascular bundle, and metaxylem cell areas. When compared to the E3 ecotype, the E1 and E2 ecotypes showed striking improvements across the board in leaf anatomy. Mechanistic links between architectural and physio-biochemical alterations are crucial to the ecological survival of different ecotypes of Phragmites karka in coastal environments affected by climate change. Their robustness and capacity to reduce pollution can help coastal ecosystems endure in the face of persistent climate change.

Chinnadurai S, Elavarasan K, Geethalakshmi V, Kripa V, Mohamed KS. Temperature, salinity and body-size influences depuration of heavy metals in commercially important edible bivalve molluscs of India. CHEMOSPHERE 2022; 307:135879. [PMID: 35926743 DOI: 10.1016/j.chemosphere.2022.135879] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 06/10/2022] [Accepted: 07/26/2022] [Indexed: 06/15/2023]
Abstract
The effect of temperature, salinity and body-size on depuration of naturally accumulated heavy metals in clams, mussels and oysters harvested from Ashtamudi and Vembanad estuaries of Kerala, India were investigated using a static depuration system. Before depuration, the concentrations of heavy metals such as Ni, Co, Fe, Mn, Cu, Pb and Zn were analysed and it was found that the Fe, Zn, Cu and Pb contents in all the three bivalve molluscs were above the prescribed limit which poses a significant health risk to bivalve consumers. To protect consumer food safety, depuration experiments were conducted at varying temperatures, salinities and body-sizes. The clams, mussels and oysters depurated under the room temperature depuration system (RTDS) showed a better reduction of heavy metals compared with low-temperature depuration system (LTDS). ANOVA showed clams and mussels depurated at RTDS significantly (p < 0.05) reduced the heavy metals than LTDS. However, there was no significant (p > 0.05) difference in oysters between RTDS and LTDS. Further, clams and mussels depurated at low salinity (15-psμ) showed high resistance against Pb reduction. But, all the heavy metals, particularly, Pb, Fe, Zn and Cu were effectively removed at higher salinity depuration (25-psμ and 35-psμ). Moreover, irrespective of the body-size of clams, mussels and oysters used for depuration, a significant (p < 0.05) reduction in all metals (Ni, Co, Fe, Mn, Zn, Pb and Cu) was observed. Relatively, the medium-size bivalves showed higher reductions compared to small-size bivalves. Based on the experiments conducted, we recommend 48 h depuration using the static system under room temperature (30 ± 1 °C) with a salinity range of (25-35 psμ) using medium-size bivalves (clam>30 mm; mussel >45 mm, and oyster >65 mm length) as optimum conditions for producing safe bivalves for consumption in the tropics.

Abstract
The biological processes of Chlamys farreri (C. farreri), an economically important shellfish, are affected when exposed to Cd2+. In this study, changes to biological processes and metabolite levels in C. farreri were examined when exposed to Cd2+. Ultra-performance liquid chromatography-tandem TOF mass spectrometry (UPLC-TOF/MS)-based untargeted metabolomics was used to examine changes in the metabolism of C. farreri gill tissue exposed to 0.050 mg/L Cd2+ for 96 h in a natural environment. Sixty-eight metabolites with significant differences were screened by multivariate statistical analysis. Eleven enriched functional pathways displayed significant changes in inactivity. Differential metabolites, mainly C00157 and C00350, have a significant impact on functional pathways and can be used as potential major biomarkers. Lipid phosphorylation, disruption of signal transduction, and autophagy activation were observed to change in C. farreri when exposed to Cd. The metabolome information supplements research on C. farreri exposure to heavy metals and provides a platform for further multi-omics analysis.

Liu Q, Yang C, He J, Meng X, Cao L, Liu B. Depuration cadmium on physiological status and biological response of Chlamys farreri using the combination of ZnSO4, EDTA-Na2 and sodium citrate. CHEMOSPHERE 2021; 263:127802. [PMID: 33297000 DOI: 10.1016/j.chemosphere.2020.127802] [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: 05/21/2020] [Revised: 07/20/2020] [Accepted: 07/21/2020] [Indexed: 06/12/2023]
Abstract
Effective removal of cadmium (Cd) from Chlamys farreri by introducing ZnSO4, EDTA-Na2, and sodium citrate into seawater has previously been reported. However, some mechanisms underlying this removal are not clear. To address this lack of clarity, the present study aimed to investigate the changes of Cd forms in Chlamys farreri from treatment of these additives and analyze the physiological and biochemical responses by comparing the changes over treatment time in Catalase (CAT), Superoxide dismutase (SOD), and Glutathione s-transferase (GST) activity, as well as Malonaldehyde (MDA) concentration and glycogen level. Three forms of Cd, including protein -Cd, liberated Cd, and amino acid/peptide -Cd, were found, and they were sorted according to their Cd content into the following groups: protein -Cd > liberated Cd > amino acid/peptide-Cd. The removal rates of the three forms of Cd were 43.2%, 59.5%, and 59.0%, respectively, using ZnSO4 and EDTA-Na2. Additionally, a significant increase in Zn content was observed, which may suggest that reduction of bound Cd was partly due to the displacement of Cd by Zn. Moreover, Cd depuration using the additives can mitigate oxidative stress only in the first 12 h. Glycogen content continued to reduce over time, inferring that the healthy status of Chlamys farreri under treatment of the additives containing Zn can only be maintained within 12 h for excreting Cd when linking these physiological responses with the ability of the additives to remove Cd only in a short time, i.e. 12 h. The results indicated that Cd should be removed from Chlamys farreri for practical reasons.
