迁安县水泵厂镀铬车间排放的废水中含有六价铬等毒性物质,十几年来废水未经处理直接排入7m深的废水井中,严重污染了附近居民饮用的井水。经对附近100眼饮用井水采用二苯碳酰二肼法进行检验,其中45眼井水中六价铬超过国家标准,超标范围3～107倍,平均10.6倍,污染面积121200m~2。 居民饮用被铬污染的井水后,出现食欲不振、口鼻发干、腹胀腹泻、皮疹、口腔粘膜溃疡等症状,对污染区居民655人体检发现,具有以上症状
Qian’an pump plant chrome plant wastewater discharge contains hexavalent chromium and other toxic substances, more than a decade of untreated wastewater directly into the 7m deep wastewater wells, seriously polluted the nearby residents drinking well water. The drinking water of 100 nearby wells was tested by diphenylcarbazide method. Among them, the concentration of hexavalent chromium in 45 wells exceeded the national standard by 3 to 107 times, an average of 10.6 times and the pollution area was 121200 m ~ 2. Residents drinking chrome contaminated well water, there appetite, nose and mouth dry, abdominal distension and diarrhea, rash, oral mucosal ulcers and other symptoms of 655 residents in contaminated areas found that physical examination, with the above symptoms
