BACKGROUND Key climatic factors influencing the transport of pesticides to drains and to depth were identified. Climatic characteristics such as the timing of rainfall in relation to pesticide application may be more critical than average annual temperature and rainfall. The fate of three pesticides was simulated in nine contrasting soil types for two seasons, five application dates and six syn...

a constant problem in the production, maintenance, and use of agricultural pesticides, is their physical-chemical corrosive properties in contact with machines and equipment. the present study attempted to increase the corrosion resistance of steel parts to agricultural pesticide with the application of appropriate thin tio2 nanoparticle coatings. this coating was applied on mild steel coupons ...

This study examines the effect of pumping, hydrogeology, and pesticide characteristics on pesticide concentrations in production wells using a reactive transport model in two conceptual hydrogeologic systems; a layered aquifer with and without a stream present. The pumping rate can significantly affect the pesticide breakthrough time and maximum concentration at the well. The effect of the pump...

Irrational use of pesticides is increasingly threatening our ecosystem, health and environment. This study investigated the use of pesticides in vegetable farms and its impact on health and environment. Three contrasting sites under three sub-districts where vegetable production were common were considered for this study. From each sub-district 60 farmers who had been using pesticides applicati...

A season-long assessment of acute pesticide poisoning among farmers was conducted in three villages in India. Fifty female cotton growers reported the adverse effects experienced after exposures to pesticides by themselves and by their male relatives (n=47). The study documented the serious consequences of pesticide use for the health of farmers, particularly women field helpers. Typically fema...

OBJECTIVE The objective of this paper was to review the effectiveness of interventions to reduce pesticide overexposure and poisonings in worker populations. METHODS We used the Cochrane Collaboration search strategy to search the following databases for articles that tested the effectiveness of interventions in reducing human pesticide exposure or poisonings: MEDLINE, EMBASE, and Occupationa...

The present study aimed to assess the environmental fate of the insecticide and nematicide ethoprophos in the soil-water interface following the pesticide application in simulated maize and potato crops under Mediterranean agricultural conditions, particularly of irrigation. Focus was given to the soil-water transfer pathways (leaching and runoff), to the pesticide transport in soil between pes...
