饮水干预对地方性砷中毒病区居民尿砷值影响的研究

Interventional study on reflecting residents' value of Urinary arsenic in the area of endemic arsenism

本文用流行病学现场干预实验方法,在人群中以现场实验手段去除砷这一致病因素后,在临床症状、体征和实验室检查方面取得了相应肯定的效果。患病率由29.15%降到13.35%,好转率高达72.62%。尿砷由0.673ppm 降至0.162ppm,恢复正常百分率为26.4%,因此,认为现场改水干预实验是防治地方性砷中毒的治本措施。

Residents exposed to high arsenical water epidemiologicaly surveyed with thefield interventional experiment in Kuitun area of xin Jiang。After riddingarsenic from drinking water,the morbidity rate of arsenism has been reducedfrom 29.15 percent to 13.35 percent and 72.62 percent of chronic arsenism showedimprovements of the health conditions,at the same time,the mean arsenicconcentration in the urine of these residents was made less from geometric meanof 0.673 mg/Litre (SDDC method) to geometric mean of 0.162mg/Litre,which was more than 2 times higher than that of normal urinary values.Fromhere we see that drinking normal water could help fo progressively eliminatearsenic storage from the chronic arsenism and that the interventional studyimproved water is an important measure in the respect taking precautions againstendemia.
