Beginning in 2003, non-point source pollutants, such as pesticides, automobiles, and household insecticides, will be subject to the examination by the Toxics Release Inventory(TRI).

Non-point pollutants, pesticides and household insecticides, and other non-point source pollutants are regularly exposed to the public without any preventive measures or facilities, but nothing is done to examine the damage or study the current status of the emissions. Also, hazardous chemical substances are emitted from all stages of the product manufacturing, distribution, and consumption processes.

The Ministry of Environment plans to build a sustainable system to reduce the chemical substance emissions by gradually expanding the scope of the Toxics Release Inventory(TRI) to equal the level of the advanced countries.
