The objective of this study was to evaluate the efficiency of nematodes in zooremediation of chlorpyrifos (CPF), an organophosphate pesticide. The nematode population Acrobeloides maximus (A. maximus) was employed for bioremediation, converting CPF into non-toxic residues. Optimal growth conditions for mass production of A. maximus were achieved by maintaining a temperature of 25 °C, pH 8, and supplementing the culture medium with plant nutrients. The nematodes were then immobilized within sodium alginate beads. The efficacy of the degradation process was assessed using various analytical techniques, including UV-Visible spectroscopy, HPTLC, FTIR, and LC-MS, confirming the successful breakdown of CPF. The bioreactor demonstrated a complete degradation efficiency of CPF exceeding 99%. Additionally, LC-MS analysis was conducted to elucidate the degradation pathway based on the formation of intermediates. These results underscore the potential of A. maximus as a sustainable organism for addressing environmental contamination arising from CPF pesticide.

Background: The unregulated use of pesticides by farmers, for crop productivity results in widespread contamination of organophosphates in real environmental samples, which is a growing societal concern about their potential health effects. The conventional approaches for the monitoring these organophosphate-based pesticides which include immunoassays, electrochemical methods, immunosensors, various chromatography techniques, along with some spectroscopic methods, are either costly, sophisticated, or involves the use of different metal complexes. Therefore, there is an urgent need for sensitive, quick, and easy-to-use detection techniques for the screening of widely used organophosphate-based pesticides.

Organophosphate pesticides (OPPs) are widely used chemical pesticides in all the developed countries. Among the OPPs, Chlorpyrifos (CPF) is predominantly used and has been linked to various adverse health effects from acute to chronic exposure. Exposure to pesticides both occupationally and environmentally causes frequent human health problems including neurological disorders, liver, kidney dysfunctions and cancer.

Chlorpyrifos (CPF), a widely used organophosphorus pesticide, presents substantial risks to both environmental and human health due to its persistent accumulation, thereby necessitating the development of effective detection methods. Self-powered photoelectrochemical (PEC) sensors, as an innovative technology, address the limitations inherent in conventional sensors, such as susceptibility to interference and inadequate signal response. Herein, we synthesized AgS/BiOCl as a photosensitive material, employing it as a light-harvesting substrate and a signal-transducing platform to develop a self-powered PEC sensor for the detection of CPF.

Chlorpyrifos (CPF) is a broad-spectrum organophosphate chloride (OP) insecticide widely used in domestic use and open field. However, there is currently no relevant research revealing the toxic effects of CPF exposure on the skin, then it is necessary to comprehensively understand the toxic effects and mechanisms. The results showed that the skin tissue structure and function of mice were significantly disrupted after CPF exposure.

A sensitive and efficient fluorescent sensor based on a magnetic manganese-doped zinc sulfide molecularly imprinted probe (FeO/Mn-ZnS/MIP) was successfully developed for the detection of chlorpyrifos (CPF). The probe combined the advantages of magnetic separation, the fluorescence properties of Mn-ZnS, and the exceptional molecule recognition capabilities of molecularly imprinted polymers. The developed sensor exhibits selective binding to CPF, resulting in a quenching of fluorescence intensity of FeO/Mn-ZnS/MIP by a photo-induced electron transfer mechanism.
