1. Aquatic and terrestrial monitoring
Based on regulations such as the Water Pollution Control Law, we monitor water
pollution sources and improper disposal of industrial waste. In case of accidents such
as oil spills, we assess the effects on the water quality and atmosphere in order to
contain the damage. In addition, we analyze water quality to conserve the
environment in specific areas such as major swimming areas, Lake Nishi-no-ko, and
Lake Yogo.
Furthermore, we inspect the water quality of Lake Biwa and the Seta River to
assess compliance with environmental quality standards.

2. Biological monitoring
We monitor the plankton responsible for causing blue-green algal blooms and
analyze trends in their abundance.
Furthermore, based on the Water Pollution Control Law, we measure the total
coliform bacterial count in Lake Biwa and the Seta River to evaluate whether it meets
environmental quality standards.

3. Air quality monitoring
Based on government regulations such as the Air Pollution Control Law, we
monitor sources of atmospheric pollutants such as flue gas of various facilities,
specific pollutants including asbestos, and roadside air that is affected by automobile
exhaust.
Furthermore, we evaluate compliance with environmental quality standards
through the use of Continuous Atmospheric Monitoring Stations and a mobile
Environmental Monitoring Laboratory. In addition, we assess the concentrations of
hazardous substances that have the potential to harm humans through long-term
exposure, as well as other chemical substances that are discharged into the air
abundantly.

|
Monitoring of air pol-lution sources |
* Flue gas emissions from facilities that are subject to control by the law
* Asbestos sources
* Specific air pollutants such as antimony
|
|
|
Analysis of the atmo-spheric environment |
* Pollution characteristics of photochemical oxidants
* Environmental concentration of asbestos
* Automobile exhaust gas
|
|
|
Evaluation of environ-mental quality stan-dards |
* Continuous Atmospheric Monitoring Stations (9 sites)
* Mobile Environmental Monitoring Laboratory
* Hazardous atmospheric pollutants (19 kinds)
* Chemical substances that are discharged in large amounts (7 kinds)

4. Chemical monitoring
We monitor chemical substance infiltration around pollution sources such as
contaminated wells and also analyze the residual state of the persistent organic
pollutants in Lake Biwa.
Furthermore, based on the Water Pollution Control Law, we assess compliance
with environmental quality standards for human health hazards and other monitored
substances in Lake Biwa and the Seta River.

Monitoring of chemi-cal substance sources |
* Effects of personal watercrafts on water quality
* Chemical substances around contaminated wells

|
Determination of cur-rent conditions of chemical substances |
* Tracking research in specific environments
