摘　　要：目的了解江苏省高砷水源分布和地方性砷中毒(简称地砷病)病情。方法在全省重点可疑地区进行高砷水源筛查,对6个市、20个县(市、区)进行水样采集和水砷含量检测,对水砷含量≥0.05 mg/L的村进行地砷病病情调查,依据《地方性砷中毒诊断标准》进行地砷病诊断。结果 2004-2008年全省高砷水源筛查共调查1 934个村,发现超标村37个;共采集水样40 060份,检测出超标水样427份。高砷村分布在沿淮河和洪泽湖周边的淮安XY、JH、HZ、宿迁SH及靠近安徽的徐州SN5个县。2008年地砷病病情调查显示,患者总检出率7.42%,轻度及以上检出率2.70%,病情较轻。结论江苏省的高砷区主要呈沿淮河与洪泽湖周边及靠近安徽分布,地砷病病情虽较轻,但防治工作仍不能忽视,建议进一步加强水砷筛查、病情调查、健康教育和监测工作。Objectives in Jiangsu province. Methods To explore the distribution of water with high level arsenic and prevalence of arsenism High arsenic water was screened in focused suspicious areas. Water samples were collected and tested from 20 counties of 6 cities. Samples with arsenic level higher than 0.05 mg/L were investigated by epidemiological method and the patients were diagnosed by Stantard of Diagnosis for Endemic Arsenism. Results 1 934 villages were investigated to screen water to determine arsenic level in 2004 - 2008, of which 37 villages had arsenic level higher than 0.05 mg/L. All 40 060 water samples were tested, and 427 of them were exceeding the level of 0.05 mg/L. Villages with arsenic content over standard level are distributed in the counties of XY, JH, HZ of Huaian city and SH of Suqian city, which are along the Huaihe River and the surrounding areas of the Hongze Lake, and in the county of SN of Xuzhou city which is near the Anhui province. The epidemiology investigation in 2008 showed that total detected rate of endemic arsenic disease was 7.42% , and detected rate of mild and more severe patiednts was 2.70%. Condition of arsenism is mild. Conclusions Areas with high arsenic level in Jiangsu Province were distributed along the Huaihe River and the surrounding areas of the Hongze Lake and near Anhui province. Ahhough the condition of arsenism is mild, prevention can not be ignored. It is recommended to further strengthen water screening for arsenic content, investigations on condition of endemic arsenism, health education and monitoring.
