目的了解山西省饮水型地方性砷中毒病情动态和防治措施落实情况,为下一步开展防治工作提供科学依据。方法按照国家《饮水型地方性砷中毒监测方案》和《2013年山西省饮水型地方性砷中毒监测方案》的要求,在全省选择5个病区县、14个病区村作为监测点,调查监测村的改水及改水工程运行情况、测定水砷含量,同时对监测村常住人口进行地方性砷中毒病情调查,并测定尿砷含量;水砷、尿砷含量测定采用氢化物原子荧光光度法(GB/T5750.6-2006),砷中毒诊断采用《地方性砷中毒诊断标准》(WS/T 211-2001)。结果 14个监测村已全部改水,改水率100.00%,改水工程全部正常运行,且水砷含量全部合格;砷中毒患者检出率为1.57%,患者以轻度为主,新发患者15例;尿砷含量测定396人,范围在0.000 2~0.380 0 mg/L,几何均值为0.005 2 mg/L。结论山西省饮水型地方性砷中毒病情总体上已减轻,但仍有新发患者,防治监测工作仍然不能松懈。
Objective To understand the status of endemic arsenism in drinking water in Shanxi Province and the implementation of prevention and treatment measures so as to provide a scientific basis for prevention and control work in the next step. Methods According to the requirements of the national “drinking water endemic arsenism monitoring program” and “2013 drinking water endemic arsenism monitoring program in Shanxi Province”, 5 ward counties and 14 ward villages were selected as the monitoring points in the province, Investigation and monitoring of village water and water diversion project operation, determination of water arsenic content, while monitoring the village resident population of endemic arsenic poisoning survey and determination of urinary arsenic content; water arsenic, urine arsenic content determination using hydride atomic fluorescence Photometric method (GB / T5750.6-2006), diagnosis of arsenic poisoning “diagnostic criteria of endemic arsenism” (WS / T 211-2001). Results All the 14 monitoring villages had been changed water, the rate of water change was 100.00%, all the water diversion works were in normal operation, and the water arsenic content was all qualified. The detection rate of arsenic poisoning patients was 1.57% 15 cases. The urinary arsenic content was 396 in the range of 0.0002 ~ 0.380 0 mg / L with a geometric mean of 0.005 2 mg / L. Conclusion The endemic arsenism in drinking-water in Shanxi Province has been alleviated overall, but there are still new-onset patients. Prevention and control of monitoring work still can not be relaxed.
