Twenty-five farm (F) households and 25 nonfarm (NF) households in Iowa were enrolled in a study investigating agricultural pesticide contamination inside homes. Air, surface wipe, and dust samples were collected. Samples from 39 homes (20 F and 19 NF) were analyzed for atrazine, metolachlor, acetochlor, alachlor, and chlorpyrifos. Samples from 11 homes (5 F and 6 NF) were analyzed for glyphosat...

Exposure to certain environmental toxicants may be associated with increased risk of developing diabetes. The authors’ aim was to investigate the relation between lifetime exposure to specific agricultural pesticides and diabetes incidence among pesticide applicators. The study included 33,457 licensed applicators, predominantly non-Hispanic White males, enrolled in the Agricultural Health Stud...

The Root Zone Water Quality Model (RZWQM) is a one-dimensional, numerical model for simulating water movement and chemical transport under a variety of management and weather scenarios at the field scale. The pesticide module of RZWQM includes detailed algorithms that describe the complex interactions between pesticides and the environment. We have simulated a range of situations with RZWQM, in...

The vital importance of agriculture is well-recognised, as is the usefulness of pesticides in increasing agricultural yields and reducing spoilage rates. The usefulness of pesticides in mitigating diseasecarrying pests (eg, mosquitos) is also well known. However, there are also risks associated with pesticide use. In addition to causing acute poisoning, they are also associated with increased c...
