The ability of targeted and nontargeted metabolomics to discover chronic ecotoxicological effects is largely unexplored. Fenitrothion, an organophosphate pesticide, is categorized as a "red list" pollutant, being particularly hazardous to aquatic life. It acts primarily as a cholinesterase inhibitor, but evidence suggests it can also act as an androgen receptor antagonist. Whole-organism fenitr...

AIMS To assess knowledge, attitude, practice, and toxicity symptoms associated with pesticide use and exposure among 189 farm workers in the Gaza Strip. METHODS A cross section of agricultural farm workers in the Gaza Strip were asked to fill in a questionnaire on knowledge, attitudes, practice towards pesticide use, and associated toxicity symptoms. RESULTS Farm workers reported high level...

Goal of the research is to consider main concepts used in probit-analysis method, features its application determine toxicity pesticides, particular insecticides, acaricides and fungicides.
 Methods. To method was used. It consists determining dose a substance necessary achieve certain level mortality test organisms, based on transformation S-shaped «dose-effect» curve into straight line.&...

background: since organophosphorus pesticides are widely used for industry and insect control in agricultural crops, their fate in the environment is very important. pesticide contamination of surface water has been recog­nized as a major contaminant in world because of their potential toxicity towards human and animals. the objec­tive of this research was to investigate the influence of variou...

The European Plant Protection Products Regulation 1107/2009 requires that registrants establish whether pesticide metabolites pose a risk to the environment. Fish acute toxicity assessments may be carried out to this end. Considering the total number of pesticide (re-) registrations, the number of metabolites can be considerable, and therefore this testing could use many vertebrates. EFSA's rec...
