目的了解我市居民饮水中砷、碘、氟的含量,为有效预防控制水砷、水碘、水氟型地方病的发生提供依据。方法现场调查与实验室监测。结果抽检的126份水样,水砷、水氟均符合国家标准。水碘>150.0μg/L的高碘水样2份,水碘<10.0μg/L的水样71份。水碘、水砷分别与水氟存在不完全正相关,r分别为0.521、0.427。结论我市饮水中的砷、碘、氟在安全范围内,不影响人体健康。水碘及水砷分别与水中氟化物含量的正相关性有待进一步研究。
Objective To understand the contents of arsenic, iodine and fluorine in drinking water in our city and provide the basis for the effective prevention and control of endemic diseases of arsenic, iodine and fluoride in water. Methods Field investigation and laboratory monitoring. Results The sampling of 126 water samples, water arsenic, water fluoride are in line with national standards. Water iodine> 150.0μg / L of high iodine water samples 2, water iodine <10.0μg / L of water samples 71. Water iodine and water arsenic were not completely and positively correlated with water fluoride respectively, r were 0.521 and 0.427 respectively. Conclusion Arsenic, iodine and fluoride in drinking water in our city are within the safe range and do not affect human health. The positive correlation between water iodine and water arsenic and water fluoride content needs further study.
