The committee, headed by Prof. Yasuaki Maeda, Osaka Prefecture University, was established within Global Environment Centre Foundation (GEC) in October 1997. It is composed of experts from the Environment Agency, the Osaka Prefectural Government, Osaka Municipal Government and 10 companies including manufacturers and maintainer of automatic monitoring instrument in Japan. The objective is to accumulate know-how on the environmental technology available in Japan and promote to developing countries.
- On the usage and the guidebook of the source of this database, to GEC.
- On the content of technology data, to each companies whose address is shown at the bottom of data page.
Chapter 2 Plan of Water Pollution Monitoring
This chapter explains how a water pollution continuous monitoring plan for public water areas, such as river, lakes, reservoirs, coastal water areas and underground water, should be established, including the measurement points, measurement items and frequency. Special considerations necessary for selecting installation sites and measurement methods of water pollution monitoring stations and pollution source monitoring are also covered.
Chapter 3 Overview of Water Pollution Monitoring Conducted by Local Governments in Japan
This chapter contains the examples of river water and coastal water pollution monitoring system implemented by Osaka Prefectural Government and lake water monitoring (Lake Biwa) implemented by Shiga Prefectural Government. Examples of water pollution monitoring stations and pollution source continuous monitoring also covered.
Chapter 4 Principles of Analyzers for Water Pollution Continuous Monitoring
This chapter contains overviews of the measurement principles of some analyzers such as ultraviolet visible-ray spectrophotometer and atomic absorption spectrometer used for water pollution continuous monitoring of public water areas. In addition, it is included the measurement principles of some analyzers such as dissolved oxygen (DO) meter and chemical oxygen demand (COD) analyzer used for water pollution monitoring stations and pollution source continuous monitoring.
Chapter 5 Examples of Automatic Analyzers for Water Pollution Continuous Monitoring
This chapter contains information about some analyzers actually used in Japan, such as ultraviolet visible-ray spectrophotometer and atomic absorption spectrometer, which are used for water pollution continuous monitoring of public water areas. In addition, it is included information some analyzers such as DO meter and COD analyzer, which are used for water pollution monitoring stations and pollution source continuous monitoring.
Chapter 6 Simplified Measurement
This chapter contains information regarding a simplified measurement method, which does not use high technology analyzers, and an example of water pollution evaluation using biological indexes in rivers.
Chapter 7 Maintenance of Analyzers for Water Pollution Continuous Monitoring
This chapter contains information about the maintenance of measurement instrument, automatic analyzers and sampling equipment used for water pollution and pollution source continuous monitoring systems. Maintenance techniques and precautions are explained based on our many years of experience.
Chapter 8 Verification and Utilization of Monitored Data
This chapter contains information on how measurement data is verified, published and used in Osaka Prefectural Government and Osaka City Government.
