Pesticide Use and Residual Occurrence in Thailand

Abstract

This paper addresses pesticide use, environmental problems, and regulations in Thailand. Annually, Thailand imports several thousand metric tons of herbicides, fungicides, and insecticides. Agricultural goods are among the country's primary exports. Over the past decade, Thailand's agricultural sector has shifted from labor- to machine-intensive farming practices. Pressures to sustain high crop yields have led to heavy usage of pesticides. Residues, especially organochlorine and organophosphate compounds, have been found in soil, water, and agricultural products throughout the country. Occupational exposure and suicide are the main causes of pesticide poisoning to Thailand's residents. Recognizing the growing problem, Thailand's government has enacted environmental laws and education programs aimed at minimizing adverse effects of pesticides.
