本文对新疆奎屯地区地方性砷中毒病区居民发砷值及头发超微结构进行了研究。结果表明:砷中毒病区居民发砷值显著高于对照区,病区中有砷中毒皮肤病变的患者其发砷值高于非患者; 扫描电镜下观察头发表面超微结构的变化,发现砷中毒病区居民毛小皮出现明显的病理变化。病区改用符合卫生标准的水后,经过两年的时间、发砷值降低到接近正常95%上限值1.5μg/g;扫描电镜下观察。毛小皮的结构基本恢复正常。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性危害。作者认为,用发砷值来评价地方性砷中毒病区改水效果是较为敏感和客观的适宜指标。
In this paper, the arsenic value and hair ultrastructure of residents in endemic arsenism area in Kuitun, Xinjiang were studied. The results showed that: the arsenic poisoning area residents hair arsenic was significantly higher than the control group, the ward in patients with arsenic poisoning skin lesions hair arsenic higher than non-patients; under the scanning electron microscope to observe the hair surface ultrastructure changes found arsenic Poison ward residents Mao Xiaopi significant pathological changes. Ward to use hygienic standards to switch to water, after two years, hair arsenic value decreased to nearly normal 95% upper limit of 1.5μg / g; under scanning electron microscope. The structure of the fur skin basically returned to normal. The findings also suggest that attention should be paid to the potential hazards of arsenic in endemic arsenism to non-patients. The author believes that the use of hair arsenic value to assess the efficacy of endemic arsenic poisoning water diversion effect is more sensitive and objective suitable indicators.
