安徽省饮用天然矿泉水类型及分布特征研究

依据矿泉水特征化学组分对安徽省饮用天然矿泉水类型进行分析,从区域、主要类型和珍稀类型三个方面研究了安徽省饮用天然矿泉水的分布特征,结果显示:按矿泉水特征化学组分可将安徽省天然矿泉水分为12种类型,其中,锶型、偏硅酸型、锶偏硅酸型为主要类型,占全省矿泉水井(泉)点总数的76.67%。锶型矿泉水分布以合肥市分布较为集中,皖南分布较少;偏硅酸型矿泉水以黄山、淮南、六安等市分布较为集中;锶偏硅酸型矿泉水则集中分布在合肥、蚌埠、滁州、六安、宿州、安庆、池州、铜陵、芜湖等市。研究结果对安徽省饮用天然矿泉水资源的开发利用具有一定的指导意义。

Organochlorine pesticides characteristics in water column of strategic drinking water sources in the Yangtze estuary

Biandansha, Qingcaosha and Meimaosha sands located respectively in the upper, middle and lower reaches of the Yangtze （Changjiang River） estuary are regarded as strategic drinking water sources of Shanghai City. In the coming decade, the Qingcaosha Reservoir will first be built and gradually take the place of present water sources in the Huangpu River. However, there is little report on the occurrence of persistent organic pollutants （POPs） such as organochlorine pesticides （OCPs） in those strategic water sources. Water samples collected from those strategic water sources were filtered in-situ by Whatman GF/F filters in April 20-23, 2006. Pesticides in the filtrates were enriched on ENVI-18 solid phase extraction （SPE） tubes. OCPs eluted from SPE tubes were determined by GC-μECD method with a mixed standard solution of 20 OCPs compounds. Pentachloronitrobenzene was added as internal standard. Total concentrations of OCPs varied between 15.1 and 83.1 ng/L in water samples from Shanghai strategic water sources. A half of twenty objective OCPs compounds including DDTs were not detected. In Qingcaosha waters, there were six compounds such as a-HCH, dieldrin, endrin, endrin ketone, β-endosulfan and endosulfan sulfate. Total concentrations of these OCPs ranged from 15.1 to 31.6 ng/L and averaged 19.9 ng/L. OCPs had higher concentrations at low water tide than at high water tide, and in bottom water than in surface water. In Biandansha and Meimaosha waters, lindane （T-HCH） of 9.0 ng/L and γ-chlordane of 8.8 ng/L were found, respectively. There was no significant difference between total OCPs concentrations in surface water from Biandansha and Qingcaosha, which are much lower than those in the downstream Meimaosha waters.     

运城关帝锶—偏硅酸饮用天然矿泉水

山西关帝饮用天然矿泉水产出于关公故里运城市解州关帝庙。经１９９２年１０月、１９９３年４月对两处矿泉水井检测分析，并经地质矿产部、轻工业部及卫生部等职能部门联合鉴定，属锶偏硅酸—重碳酸钙—镁型饮用天然矿泉水。该矿泉地理位置优越，名胜古迹诱人，有良好的开发前景。
