Pesticides may contribute to respiratory symptoms among farmers. Using the Agricultural Health Study, a large cohort of certified pesticide applicators in Iowa and North Carolina, we explored the association between wheeze and pesticide use in the past year. Self-administered questionnaires contained items on 40 currently used pesticides and pesticide application practices. A total of 20,468 ap...

Volatilization of agricultural chemicals is one process whereby chemicals may enter into parts of the environment where they were not intended. Starch encapsulation of pesticides has been proposed as a way of modifying pesticide behavior in the soil environment. This study was conducted to assess how starch encapsulation and temperature affect volatilization of atrazine [6.chloro-N-ethyI-N’-(l-...

During 2017 the herbicides alachlor, atrazine, butachlor, metolachlor, and simazine were detected in water samples, beach sediments marine biota collected at Camps Bay, Cape Town, South Africa. that period, annual rain catchment record was 77,000 m3, whereas volume of chemically laden sewage discharged via outfall 693,500 m3 making by far most predominant source for these bay. The chemical load...

Herbicide contamination of streams has been well documented, but little is currently known about the specific factors affecting watershed vulnerability to herbicide transport. The primary objectives of this study were (1) to document herbicide occurrence and transport from watersheds in the northern Missouri/southern Iowa region; (2) to quantify watershed vulnerability to herbicide transport an...

Custom applicators intensively apply herbicides to corn and soybean fields each spring. The primary objective of this study was to characterize the exposure distributions of the herbicides alachlor, atrazine, 2,4-D 2-ethylhexyl ester (2,4-D EH), and metolachlor among a group of applicators during the spring pre-emergent spray season. A secondary objective was to evaluate determinants of exposur...

In the present study, performance of mixed microbial anaerobic culture in treating synthetic strong wastewater containing different concentration of atrazine was evaluated (R-1). Studies were also conducted in two hybrid reactors (A-1 and A-2) with wood charcoal as adsorbing matrix along with microbes. All the reactors for the treatment of atrazine bearing wastewater were operated in sequential...
