Between 1953 and 1960, 110 people in Japan’s Minimata Bay area died mysteriously. Studies showed that people had eaten fish in which quantities of mercury(汞)were found. Where did it come from? It was poured into the bay by a plastics plant. The Japanese government closed that plant and started strictly controlling the use disposal(处理)of mercury compounds(化合物).But this didn’t prevent another terrible event.
In 1965, 26 people at Nigata, Japan, were struck by mercury poisoning. Five died. All of them had eaten fish with mercury in it. And again it was caused by a plastics plant.
Events like these are not limited to agriculture or plastics plants. Because of such events, however, it is clear that we must maintain a close watch over our practices concerning poisons, foods and water. Indeed, in our industrial age close watch may forever be the price of health.
