摘要
目的:通过水质检测了解贵州敦寨地区尿石症高发流行病特点,调查其发病原因。方法:对当地分散式饮用水源按GB-T5750-2006《生活饮用水标准检验方法》要求采样检测,感官性状,一般化学指标,污染指标17项:色度、浑浊度、臭和味、肉眼可见物、pH、电导率、氯化物,溶解性总固体,总硬度(永久性硬度、暂时性硬度)、化学需氧量、氨氮、亚硝酸盐氮、铁(二价)、锰、铜、锌、钠。毒理学指标5项:铬(六价)、氟化物、硒、铅、镉。并按照国家《生活饮用水卫生标准》给予评价。结果:该地区水质暂时性硬度偏高,个别样品臭和味、肉眼可见物、铁等超出国家标准,浑浊度(P<0.05)、氨氮(P<0.05)、化学需氧量(P<0.05)。结论:该地区尿石症的高发主要受环境、生活习惯、卫生水平的影响,与水质有很大关系。
Objective： To understand the epidemiological features and the causes of incidence of urolithiasis in Dunzhai area of Guizhou through water quality detection. Methods： According to GB -T5750 -2006 ＂Standard inspection methods for drinking water＂, the source of distributed drinking water was sampled for detection of the sensory properties, general chemical parameters, 17 items of pollution indicators such as chroma, turbidity, smell and flavor, visible substance, PH, electrical conductivity, chloride, total dissolved solids, total hardness of water（ permanent and temporary hardness）, chemical oxygen demand（ COD）, ammonia, nitrite, Fe, Mn, Cu, Zn and Na, and five items of toxicology indicators such as Cr（hexavalent）, F, Se, Pb and Cd. Then the results were evaluated in accordance with national ＂Hygienic standard for drinking water＂. Results： The drinking water in this area presented high temporary hardness, while some samples showed the smell and flavor, visible substances and Ire exceeded the national standard, turbidity （ P 〈 0.05 ）, ammonia （ P 〈 0.05 ）, COD （ P 〈 0.05 ）. Conclusion： The high incidence of urolithiasis was mainly related to living environment, living habits, health level and water quality in the local area.
