辽宁省宽甸水体中硼的环境地球化学特征研究

The Research of Environmental Geochemical Characteristics of Boron in the Water of Kuandian County,Liaoning Province

在宽甸地区的地表水系(鸭绿江、蒲石河、南股河、北股河、爱河等),地下水及饮用水系布设采样点共采集样品56个并采用等离子质谱(Excell)及等离子光谱(IRIS)进行硼含量分析.由此揭示水体中硼的来源、分布、运移和聚集等情况,并且根据国家《农田灌溉水质标准》(GB5084-92)中关于硼和pH的规定分析评价了宽甸地区地表水体的灌溉能力以及根据卫生部《生活饮用水水质卫生规范》中关于硼和pH的规定分析评价了饮用水的安全程度.结果表明,宽甸地区未受硼矿开发影响的水体基本适合农业灌溉或饮用,而在硼矿开发区范围内,受到硼矿开发影响的水体大部分不适合灌溉,或不适合饮用.

By disposing sampling sites for surface water system （Yalvjiang River, Pushi River, Nangu River, Beigu River and Aihe River, etc. ）, ground water system and drinking water, 56 samples were collected and analyzed on boron using Excell and IRIS. By the way, the origin, the distribution, the movement and the collection of the boron in water can be revealed. The irrigation capability of surface water is then evaluated according to the national standard for irrigation water quality, and the safety of drinking water can also be evaluated according to the national sanitary standard of drinking water quality about pH and boron. The result is that the water body not affected by boron exploitation is suitable for irrigation or drinking basically, but the water body affected by boron exploitation is not suitable for irrigation or drinking.
