为研究石门雄黄矿附近地区人群慢性砷中毒的患病率及其分布特点，采用现况调查研究方法，以雄黄矿排放洗矿水河流下游的三个村庄为污染区，另选一个远离矿区无污染的村庄为对照，每个村子各选取在当地居住五年以上，无职业性砷接触史的居民约２００人，进行体检并填写健康调查问卷。污染区三个村慢性砷中毒患病率分别为３６．５％、２４．７％和１８．２，对照村为０％。患病率分布特点是距离雄黄矿越近患病率越高；年龄越大患病率越高；男性患病率高于女性。这说明暴露水平与患病率存在联系
In order to study the prevalence and distribution of chronic arsenic poisoning in the population around Shimen Xiong Huang mine, three village villages downstream of the mining river are polluted by the current status of research and study, and the other one is far away from the mining area Polluted villages as a control, each selected for each village more than five years living in the local, non-occupational arsenic exposure history of about 200 residents, physical examination and fill in the health questionnaire. The prevalence of chronic arsenism in the three villages in the polluted area was 36.5%, 24.7% and 18.2%, respectively, compared with 0% in the control village. The distribution of the prevalence is characterized by the closer the distance between the realgar and the higher the prevalence; the higher the prevalence, the higher the prevalence; the prevalence of males is higher than that of females. This shows that the level of exposure and prevalence are linked
