新疆地方性砷中毒地区人群头发的伸长和相对强力的研究

Research of the Stretch and Relative Strength of Hair in Endemic Arsenism Area in Kuitun District, Xinjiang

作者对新疆奎屯地方性砷中毒病区居民的头发进行了研究,结果表明:病区中砷中毒患者与非患者之间头发的伸长和相对强力无显著性差异,而与对照区居民相比,病区居民头发的伸长和相对强力均明显降低。病区居民改用符合卫生标准的水两年后,头发的伸长和相对强力明显增加。调查结果还提示,应注意地方性砷中毒病区砷对非患者的潜在危害。作者认为,用头发的伸长和相对强力来评价地方性砷中毒区的改水效果是较为敏感和客观的适宜指标。

This paper reports the results of research of hair in the endemic arsenism area where water with arsenic content was 0.58 mg/L in Kuitun district, Xinjiang. The stretch and relative strength of hair in the area of endemic arsenism were lower than the areas of control. By using hygienic standard(the arsenic content being 0.03mg/L)to improve the drinking water for two years, the stretch and relative strength of hair have distinctly increased. The results of our investigation show that we should notice the latent harmful effect to non-patients in the high-arsenic-content area. The authors consider that stretch and relative strength of hair are sensitive and objective indexes to evaluate the effects of replacing water in area of endemic arsenism.
