Biologically Based Pesticide Dose Estimates for Children in an Agricultural Community

Biologically based pesticide dose estimates for children in an agricultural community.

Current pesticide health risk assessments in the United States require the characterization of aggregate exposure and cumulative risk in the setting of food tolerances. Biologic monitoring can aggregate exposures from all sources and routes, and can integrate exposures for chemicals with a common mechanism of action. Its value was demonstrated in a recent study of organophosphorus (OP) pesticid...

Determinants of Organophosphorus Pesticide Urinary Metabolite Levels in Young Children Living in an Agricultural Community

Organophosphorus (OP) pesticides are used in agriculture and several are registered for home use. As young children age they may experience different pesticide exposures due to varying diet, behavior, and other factors. We measured six OP dialkylphosphate (DAP) metabolites (three dimethyl alkylphosphates (DMAP) and three diethyl alkylphosphates (DEAP)) in urine samples collected from ~400 child...

Developing a Model for University-Community Engagement based on Social Responsibility Approach in Agricultural Higher Education

The purpose of this research was to develop a model for university–community engagement based on social responsibility approach in agricultural higher education. Causal layered analysis was used to draw different layers of university–community engagement model. A qualitative phenomenological method was used to extract indicators for each layer.  The Nvivo10 QSR software was used for data analys...

Organophosphate pesticide levels in blood and urine of women and newborns living in an agricultural community.

Organophosphate pesticides are widely used and recent studies suggest associations of in utero exposures with adverse birth outcomes and neurodevelopment. Few studies have characterized organophosphate pesticides in human plasma or established how these levels correlate to urinary measurements. We measured organophosphate pesticide metabolites in maternal urine and chlorpyrifos and diazinon in ...
