Causes and Measures of Water Pollution [Environmental Measures VOL.4]

We will introduce the causes and measures of water pollution that have a significant impact on life and the environment.

During Japan's period of rapid economic growth, pollution-related diseases caused by environmental pollution continue to cast a dark shadow over victims, residents of affected areas, and the environment. Among pollution-related diseases, the four major diseases, which include Minamata disease, Second Minamata disease, Yokkaichi asthma, and Itai-itai disease, were particularly severe, with three of them (excluding Yokkaichi asthma) caused by water pollution. **Minamata Disease** This pollution-related disease occurred in Minamata Bay, Kumamoto Prefecture. It resulted in serious health damage due to the consumption of fish contaminated by organic mercury discharged from factories. It is also referred to as the origin of pollution. **Second Minamata Disease** This pollution-related disease occurred in the Agano River basin in Niigata Prefecture. It resulted in serious health damage due to the consumption of fish contaminated by organic mercury discharged from factories. **Itai-itai Disease** This pollution-related disease occurred in the Jinzū River basin in Toyama Prefecture. It resulted in serious health damage due to the consumption of rice grown in water contaminated by cadmium discharged from mines. This time, I would like to address water pollution, which has a significant impact on life and the environment.
