Residential proximity to applications of agricultural pesticides may be an important source of exposure to agents that have been classified as developmental toxins. Data on two case-control study populations of infants with neural tube defects (NTDs) and nonmalformed controls delivered in California between 1987 and 1991 were pooled to investigate whether maternal residential proximity to appli...

In Part I of this work we presented pesticide levels in the surface waters of the Lower Fraser Valley (LFV) region of British Columbia, Canada. In Part II pesticide levels in the groundwater of the LFV are presented. During the period 2003 to 2005 a study was conducted to determine the occurrence and spatial distribution of 78 pesticides in the groundwater of the LFV. Samples were collected and...

BACKGROUND Pesticide poisoning is a global health issue with the largest impacts in the developing countries where residential and small-scale agricultural areas are often integrated and pesticides sprayed manually. To reduce health risks from pesticide exposure approaches for personalized exposure assessment (PEA) are needed. We present a conceptual framework to develop a spatial individual-ba...

In Thailand’s agricultural communities, a number of pesticide products have been frequently used in agricultural farms and this is raising concerns about potentially adverse effects on human health and environment in the community. The objective of this study was to investigate residential pesticide exposure in farm and non-farm families in an agricultural community in Ubonratchathani province,...

We investigated the determination of N-methylcarbamate pesticides and their metabolites in agricultural products by HPLC with post-column fluorescence detection after clean-up with an SPE cartridge. The homogenate of agricultural products was extracted with acetone. The crude extract was partitioned between 5% sodium chloride solution and dichloromethane, and the dichloromethane layer was conce...

Constructed wetlands used to mitigate pesticide runoff from agricultural fields into receiving systems (e.g., lakes, rivers, streams) have been successful in reducing concentrations of non-point source pollutants such as agricultural insecticides (Moore et al., 2002; Leistra et al., 2003; Bouldin et al., 2005). Such wetlands also have important functions in enhancing the water quality and ecolo...

In April 1995, the US Geological Survey began a study to determine the occurrence and temporal distribution of 49 pesticides and pesticide metabolites in air and rain samples from an urban and an agricultural sampling site in Mississippi. The study was a joint effort between the National Water-Quality Assessment and the Toxic Substances Programs and was part of a larger study examining the occu...

BACKGROUND Agricultural pesticide self-poisoning is a major public health problem in rural Asia. The use of safer household pesticide storage has been promoted to prevent deaths, but there is no evidence of effectiveness. We aimed to test the effectiveness of lockable household containers for prevention of pesticide self-poisoning. METHODS We did a community-based, cluster-randomised controll...

In order to ensure edible safety, more regard has been paid to pesticide contamination on agricultural product. Conventional techniques are used to measure pesticide contamination. However, the conventional analyses are not possible because of their destructive characteristic and the limitation of time and labor. Spectral technique can provide a rapid, nondestructive means to assess quality and...
