Rice production is one of the major non-point sources of pesticide pollution in Japan. Monitoring of pesticide concentrations in river systems detected a number of herbicides commonly used in paddy fields, and these concentrations may appear to have adverse effects on the aquatic ecosystem. In this paper, two mathematical models developed in Japan, the PADDY and PCPF models for simulating the fate and transport of pesticides in a paddy environment are introduced. These models have been… CONTINUE READING
