Summary of Marine Pollution from Industrial Wastewater - September 1995

Marine pollution from industrial wastewater became more serious during Japan's period of rapid economic growth (1950s to 1970s). Wastewater containing toxic substances discharged from factories flowed into rivers and oceans, causing significant damage to fisheries and marine ecosystems. A typical example is the 1958 pollution of the Urayasu fishing grounds, where wastewater from Honshu Paper's Edogawa Mill caused devastating damage to the fishing grounds. This incident prompted the Japanese government to enact the Water Quality Protection Law and the Factory Wastewater Regulation Law, and served as an opportunity to make society aware of the importance of environmental protection. Subsequent tightening of environmental regulations and technological advances have greatly reduced marine pollution from industrial wastewater since the 1970s, but there are still concerns about pollution from microplastics and new chemical substances. Striking a balance between environmental protec
tion and industrial activities will continue to be an important challenge.
