Biomarkers of oxidative stress in atrazine-treated honey bees: A laboratory and in-hive study
… to honey bees is the unintended exposure to agricultural pesticides. Previous studies report that acute exposures to the common-use herbicide atrazine elicit oxidative stress in non-target insects; however, little information is currently available on the exposure risk of atrazine to honey …

Reproductive health effects due to pesticide exposure amongst boys in the rural Western Cape, South Africa
Contemporary agricultural pesticides have been shown to possess hormonally-active properties, and have been associated with declining male reproductive health. These chemicals act by disrupting the normal functioning of the male endocrine system, through their actions on the …

Effects of neonicotinoids and fungicides on soil invertebrate communities and litter decomposition within restored prairie
Pesticide use is widespread within agricultural landscapes, and emerging evidence suggests that both neonicotinoids and fungicides can greatly impact the health of soil invertebrate communities. My study compares soil fauna community composition, abundance, species diversity, and litter …

The Toxicity of Pesticides to Mammalian Cells as Altered by Redox-Modified Smectites
The fundamental concern about agricultural chemicals is their environmental fate and toxicologic risk to humans and other non-targeted animals. The application of pesticides to soil is typically direct or through post-emergence methods. Degradation of pesticides is typically considered to be a …
