本文对已通过鉴定的29眼饮用天然矿泉水水质进行了分析与评价,发现我省矿泉水以含锶(范围0.05~3.22mg/L,均值0.74mg/L)或含偏硅酸(范围9.7-79.8mg/L,均值39.3mg/L)或两者兼含为主。限量元素及部分化合物含量均很低,无一超标样品,微生物指标全部符合标准要求,放射性指标虽差异悬殊,但亦未超标。污染指标中亚硝酸盐和酚类化合物超标情况严重,超标率依次为16.3%和9.3%,经采取措施并加强防护后,水质好转。
In this paper, we have analyzed and evaluated the water quality of 29 drinking natural mineral water that has been identified. It is found that the mineral water of our province contains strontium (range 0.05 ~ 3.22mg / L, average 0.74mg / L) Acid (range 9.7-79.8 mg / L, mean 39.3 mg / L) or both. The content of the limited elements and some of the compounds were very low. No one exceeded the standard samples. All the microbiological indicators met the standard requirements. Although the radioactive indexes differed widely, they did not exceed the standard. Nitrite and phenolic compounds exceeded the standard in the pollution index. The over-standard rates were 16.3% and 9.3% respectively. After the measures were taken and the protection was strengthened, the water quality improved.
