Abstract

This study purposes to determine pesticides of carbamate and organophosphate group foundin soil, rice, and water samples from rice paddy fields in Village number (Moo) 4, Banpraw Sub-district, Banna District in Nakhon Nayok Province. The sampling sites were selected in 27 agri- cultural areas using Global Positioning System (GPS). It was found that 42.3 % of all surveyed farmers had used pesticides in their rice paddy fields between June 2014 to January 2015. Moreover, the soil ( =27), water (n=10) and rice (n=27) samples were tested using a GT test kit. This study reports that 77.78 %, 85.18 % and 70 % of soil, rice and water samples respectively were contaminated with carbamate and organophosphate pesticides. It demonstrated that more than 60 % of the collected samples were contaminated with the pesticides, at the significance level of (p = 0.001). Herbicides were most frequently used (62.20 %), followed by insecticides (26.83 %) and chemical control of plant diseases (10.98 %). Organophosphate group was an in-secticide that mostly used up to 50 % of the total used. Therefore, the obtained data may be further applied to improve the natural environment and to programs for health promotion of farmers.
