性质:为控制水污染、保护水资源,我国于1988年制订了地面水环境质量标准GB 3838-88。它适用于我国的江河、湖泊、水库等具有使用功能的地面水水域。依据地面水水域使用目的和保护目标分成五类:Ⅰ类,主要适用于源头水、国家自然保护区;Ⅱ类,主要适用于集中式生活饮用水水源地一级保护区、珍贵鱼类保护区、鱼虾产卵场等;Ⅲ类,主要适用于集中式生活饮用水水源地二级保护区、一般鱼类保护区及游泳区;Ⅳ类,主要适用于一般工业用水及人体非直接接触的娱乐用水;Ⅴ类,主要适用于农业用水区及一般景观要求水域。该标准给出了从水温、pH值、溶氧、生化需氧及一些水体不应有或非自然原因导致的对环境水质有影响的无机盐类、重金属元素、有害有机物等30个参数的各类标准值。
