TEMPORAL VARIATIONS AND MODELING OF AGRICULTURAL CHEMICALS IN THE OOTA RIVER BASIN

摘要

Agricultural chemicals (ACs) are used for stabilization and effectiveness of the farm production. Although many kinds of AC research have been reported, there are not much data to make AC priority lists in local areas. It is very important to make good prediction models for ACs in water source. Therefore, fifty-seven ACs were examined in the purification plants of Hiroshima city, Japan, and investigated for making a prediction by means of the statistical model.
