Two examples are the black foot disease brought about by arsenic pollution in drinking water in southwestern coastal Taiwan in the 1970's and a loss of calcium in the bones, brought on by chemicals in rice two years ago. These types of diseases have mostly occurred in industrial advanced nations.
民國六十年代台灣西南沿海因為飲用水遭砷污染引起的「烏腳病」，或前兩年發生食用含鎘米造成骨骼鈣流失，導致的「痛痛症」都是例子，這些疾病也大都在工業先進國家曾經出現。
