Abstract
Deteriorated soil pollution has grown into a worldwide environmental concern over the years. Organochlorine pesticide (OCP) residues, featured with ubiquity, persistence and refractoriness, are one of the main pollution sources, causing soil degradation, fertility decline and nutritional imbalance, and severely impacting soil ecology. Furthermore, residual OCPs in soil may enter the human body along with food chain accumulation and pose a serious health threat. To date, many remediation technologies including physicochemical and biological ways for organochlorine pollution have been developed at home and abroad, but none of them is a panacea suitable for all occasions. Rational selection and scientific decision-making are grounded in in-depth knowledge of various restoration techniques. However, soil pollution treatment often encounters the interference of multiple factors (climate, soil properties, cost, restoration efficiency, etc.) in complex environments, and there is still a lack of systematic summary and comparative analysis of different soil OCP removal methods. Thus, to better guide the remediation of contaminated soil, this review summarized the most commonly used strategies for OCP removal, evaluated their merits and limitations and discussed the application scenarios of different methods. It will facilitate the development of efficient, inexpensive and environmentally friendly soil remediation strategies for sustainable agricultural and ecological development.

Detection of Neonicotinoids in agriculture soil and degradation of thiacloprid through photo degradation, biodegradation and photo-biodegradation. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 306:119452. [PMID: 35561799 DOI: 10.1016/j.envpol.2022.119452] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 05/04/2022] [Accepted: 05/07/2022] [Indexed: 06/15/2023]
Abstract
The social and ecological influence of Neonicotinoids (NEOs) usage in agriculture sector is progressively higher. There are seven NEOs insecticides widely used for the insects control. Among the NEOs, thiacloprid (THD) was extensively used for insect control during crop cultivation. This study targets to analyse the contamination levels of NEOs in agricultural soil and identify photo-biodegradation of THD degradation using pure isolates and mixed consortium. The photo degradation (PD), biodegradation (BD) and photo-biodegradation (PBD) of THD were compared. The corn field agricultural soils were polluted by four NEOs, among them THD had greater contamination level (surface soil: 3901.2 ± 0.04 μg/g) and (sub-surface soil: 3988.6 ± 0.05 μg/g). Three soil free enriched bacterial strains following Bacillus atrophaeus (PB-2), Priestia megaterium (PB-3) (formerly known as Bacillus megaterium), and Peribacillus simplex (PB-4) (formerly known as Bacillus simplex) were identified by microbiological and molecular 16s rRNA gene sequencing. The PD, BD and PBD of THD were conducted and degradation rate was detected by instrument UPLC-MS-MS. The PBD process with blue-LEDs showed better THD degradation efficiency than PD and BD, where the specific THD degradation rate was 85 ± 0.2%, 87 ± 0.5%, and 89 ± 0.3%, respectively for PB-2, PB-3 and PB-4. Then, the photo-biodegradation performance is greater at 150, 175, 200 rpm, pH 7.0-9.0, and temperature 30-35 °C. After the PBD system deliver four intermediate metabolites, the THD degradation process maybe through nitro reduction, hydroxylation and oxidative cleavage pathway.

Appl Biochem Biotechnol 2022; 194:2747-2761. [PMID: 35267121 DOI: 10.1007/s12010-022-03869-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 02/24/2022] [Indexed: 11/02/2022]
Abstract
Endosulfan remains as a lipophilic insecticide that causes serious medical problems because of biological stability and toxicity also found in air, water, soil sediments, and foodstuffs. Henceforward, the present study reveals a novel bacterial species isolated from pesticide-contaminated soil for enhanced endosulfan degradation. Next, isolated bacterial species was characterized with biochemical assays and 16S rRNA sequencing technique. Subsequently, the optimal conditions for endosulfan biodegradation such as pH, concentration of endosulfan, and bacterial growth were estimated with non-sulfur medium (NSM). Sequentially, the amount of endosulfan and compound degradation were analyzed through thin-layer chromatography and gas chromatography/mass spectrometry. Overall, the obtained results revealed the endosulfan acting as primary carbon source for bacterial growth. From the GC-MS analysis, the metabolic products released during endosulfan degradation by Pseudomonas sp. MSCAS BT01 were compared with standard GC-MS spectra. The highest (98%) endosulfan degradation was obtained at pH 7.0. The complete endosulfan degradation was achieved at 14th day of incubation and the less toxic endosulfan diol produced was observed via GC-MS. To conclude, the pesticide-contaminated isolate Pseudomonas sp. MSCAS BT01 emerged as a promising bioremediation tool and effectively employed to degrade endosulfan from contaminated soils, sediments, and wastewaters in the days yet to come.
