Analytical Data for Agricultural Chemicals asWater Quality Control Target Setting Items

Introduction

To protect the quality of water essential to humans, drinking water quality standards have been established. Current water quality standards in Japan were significantly revised in 2003. Water quality standards based on Ordinance 4 of Japan's Water Supply Act are specified according to "Ministerial Ordinance Concerning Water Quality Standards" (Ministry of Health, Labour and Welfare Ordinance No. 101, May 30, 2003 [Final revision, Ministry of Health, Labour and Welfare Ordinance 18, February 17, 2010] ). In addition to water quality standards, items that require considerations for water quality control are specified as water quality control target setting items. Necessary information and knowledge of these items have been continuously gathered. This document is a collection of analytical data with respect to water quality control target setting items for 15 agricultural chemicals (102 components). Analyzing multiple types of agricultural chemicals requires experience and technical ability. It describes key considerations for preparing reagents, pretreating samples, and setting parameters for analytical instruments.
