A 77-year-old retired man lives in Liukuaizhuang village which, along with neighboring Xiditou village in Tianjin, rose from poor areas into economic "successes" after scores of chemical factories moved in two decades ago. The man...was diagnosed with lung cancer several years ago, which he believes was caused by years of breathing in the local chemical-filled air and drinking contaminated water. Tianjin health authorities ... said the rates of cancer in Liukuaizhuang and Xiditou were 1,313 and 2,032 per 100,000 people, way above the national average of 70 per 100,000 people. Residents say they are simply helpless to fight the factories or seek compensation as they have no legal recourse...the lack of evidence remains a problem as local government officials pressure doctors into staying silent over the link between pollution and the high cancer rate.
