PCBs and dangerous moonshine Chai Sung-lin had been campaigning tirelessly for years when in the summer of 1979, a cooking oil manufacturer in Changhua sold rice-bran oil contaminated with polychlorinated biphenyls (PCBs).

This incident drew attention to the fact that consumers lacked almost any protection.
多氯聯苯與假酒事件就這樣呼籲了好幾年，一直到民國 68 年夏天，當時中部地區民眾因為食用了彰化油脂工廠製造販賣、受到滲漏污染的米糠油，造成嚴重的多氯聯苯中毒事件，受害者多達二千餘人，且多是屬於經濟弱勢的族群，沒想到加害廠商非但不肯賠償，甚至以脫產方式來逃脫責任。
