It has become concern that pesticides applied to agricultural lands may cause adverse effects to the environment and ecosystems. Therefore, it is important to predict both environmental fate and impact to organisms of pesticides. The fact of pesticide applications was investigated in both young seedling transplanting culture (YSTC) and direct seeding culture of paddy rice on non-tilled upland field (DSC). The environmental load (runoff amount of pesticides) was calculated by the mathematical model (PADDY). The risk to aquatic organisms (Carp and Daphnia) by runoff pesticides from paddy fields was evaluated by the ratio of predicted environmental concentration (PEC) and short term effect concentration (LC50). Application amount of pesticides in DSC was more than that in YSTC. However, on the contrary, the runoff amount in YSTC was same as that in DSC. As a result of calculating the ratios (PEC/LC50), it was estimated that the adverse effect to aquatic organisms was small by a short term exposure of pesticides.
