— This paper uses a large database of laboratory test results to investigate the sources of international variation in pesticide residues on food products. We specify and estimate a model that incorporates contamination effects attributable to product pest sensitivity, pesticide toxicity levels and characteristics of the producing country. Among the latter, our model tests for the effects of in...

For the conventional vineyard, reducing pesticide usage is most important issue for converting to organic vineyard. In order study effect of on grape yeast, an investigation were designed in vintage 2020, ten vineyards (include two vineyards) with different treatment frequency index (TFI) chosen, and yeast population counted by method: cultivate method direct epifluorescence technique (DEFT). T...

Latest pesticide monitoring results suggests that there is a shift in residential pesticide exposure from organophosphorous insecticides to pyrethroid insecticides. Although it is well known that pyrethroid insecticides are potential neurodevelopmental toxicants, research pertaining to their effect, especially permethrin, has not been carried out in mice. In the present study we report the effe...

The effect of pesticide contamination of the littoral zone on the population of bacteria and fungi was analyzed using the example of a eutrophic water reservoir exposed for >30 years to the influence of expired crop-protection chemicals, mainly DDT. For three consecutive years, quantity analyses of bacteria and fungi were conducted and the composition of the microorganism population analyzed ag...

The purpose of investigation was to study the effect of pesticides from group of pyrethroids (e.g. decis) on the enzymatic function in the homogenate of the mucosal membrane of the proximal and distal segments of the small intestine. Determination of the degree of the activity of hydrolytic enzymes in the homogenates of some parts of the intestine allowed to show effect of pesticide decis on th...
