Pesticides are an important agricultural input, and the introduction of new active ingredients with increased efficiencies drives their higher production and consumption worldwide. Inappropriate application and storage of these chemicals often contaminate plant tissues, air, water, or soil environments. The presence of pesticides can lead to developing tolerance, resistance or persistence and even the capabilities to degrade them by the microbiomes of theses environments.

- Human activities and natural processes contribute to soil and water pollution with various organic chemicals, making traditional cleanup methods challenging.
- Bioremediation, which uses microorganisms to remove pollutants, is a promising and cost-effective solution but faces limitations like poor microbial effectiveness, accessibility of contaminants, and lack of standard efficacy measures.
- The review highlights knowledge gaps and evaluates remediation strategies such as composting and phytoremediation, aiming to improve the application and testing of bioremediation in polluted environments.
Article Synopsis
- Soil often contains a mix of contaminants rather than just one, making it challenging to study their effects on the environment.
- Most research has focused on single pollutants, neglecting how combinations affect beneficial microorganisms and overall environmental health.
- There's a call for improved monitoring methods and more comprehensive toxicological data on chemical mixtures to better inform regulatory decisions.
Fenamiphos and related organophosphorus pesticides: environmental fate and toxicology.
Rev Environ Contam Toxicol
February 2010
In this review, we emphasize recent research on the fate, transport, and metabolism of tree selected organophosphorus pesticides (fenamiphos, isofenphos, and coumaphos) in soil an water environments. This review is also concerned with the side effects of these pesticides on nontarget organisms. Despite the fact that fenamiphos is not very mobile, its oxides have been detected in the groundwaters of Western Australia.
