Biological monitoring of chlorpyrifos exposure to rice farmers in Vietnam.
Chlorpyrifos is the most common organophosphate insecticide registered for use in Vietnam and is widely used in agriculture, particularly rice farming. However, chlorpyrifos exposure to and adverse effects on farmers has not been evaluated. In this study, biological monitoring of chlorpyrifos exposure in a group of rice farmers was conducted after a typical application event using back-pack spr...
متن کاملDermal Absorption of Chlorpyrifos
Geer et al. (2004) provided an interesting comparison between passive dosimetry measures and biomonitoring for chlorpyrifos (CP) exposure in pesticide workers. However, they made a questionable assumption of a 3% dermal absorption factor (DAF) for CP, stating: ‘[The] study by Nolan et al. (1984), supports the use of a 3% DAF, the Environmental Protection Agency (EPA) accepted value, whereas Kri...
متن کاملLongitudinal assessment of chlorpyrifos exposure and self-reported neurological symptoms in adolescent pesticide applicators
OBJECTIVES Occupational exposure of organophosphorus pesticides, such as chlorpyrifos (CPF), in adolescents is of particular concern because of the potential vulnerability of the developing neurological system. The objectives of this study were to examine how neurological symptoms reported over the application season vary across time, whether these effects are reversible postapplication and if ...
متن کاملGas chromatographic method for assessing the dermal exposure of greenhouse applicators to dimethoate and malathion.
An analytical method is developed to determine potential and actual dermal exposure to dimethoate and malathion for agricultural workers using whole body dosimetry. The methodology described includes three different aspects: the validation of the analytical method incorporating a matrix effect for establishing performance parameters such as recovery rates (between 92% and 103% for both pesticid...
متن کاملNeurologic function among termiticide applicators exposed to chlorpyrifos.
Chlorpyrifos is a moderately toxic organophosphate pesticide. Houses and lawns in the United States receive a total of approximately 20 million annual chlorpyrifos treatments, and 82% of U.S. adults have detectable levels of a chlorpyrifos metabolite (3,5, 6-trichloro-2-pyridinol; TCP) in the urine. The U.S. Environmental Protection Agency has estimated that there are 5,000 yearly reported case...
