水质水质waterquality未经人类活动污染的自然界水的物理化学特性及其动态特征。物理特性主要指水的温度、颜色、透明度、嗅和味。水的化学性质由溶解和分散在天然水中的气体、离子、分子、胶体物质及悬浮质、微生物和这些物质的含量所决定。天然水中溶解的气体主要是氧和二氧化碳；溶解的离子主要是钾、钠、钙、镁、氯、硫酸根、碳酸氢根和碳酸根等离子。生物原生质有硝酸根、亚硝酸根、磷酸二氢根和磷酸氢根离子等。此外，还有某些微量元素，如溴、碘和锰等。胶体物质有无机硅酸胶体和腐殖酸类有机胶体。悬浮固体以无机质为主。微生物有细菌和大肠菌群。天然水评价指标一般为色、嗅、味、透明度、水温、矿化度、总硬度、氧化-还原电位、pH值、生化需氧量和化学需氧量等。天然水中的大气降水水质与当地的气象条件和降水淋溶的大气颗粒物的化学成分有关；地表水水质与径流流程中的岩石、土壤和植被有关；地下水水质主要与含水层岩石的化学成分和补给区的地质条件有关。
