陕西省府谷哈镇水环境及土壤环境现状研究
|
摘要
在进行"陕西省陕北石炭—二叠纪煤田府谷矿区马家梁-房子坪勘查区普查"项目的地质及水工环1:2. 5万地质填图中,对府谷哈镇周围部分井、泉、水库及土壤进行了采样分析,采集水样共10件,其中水质简分析4件、水质环境分析4件、水质全分析2件,采集土壤样品4件。分析结果发现该区水质多属CO32-·HCO3-·SO42--Na+·Ca2+·Mg2+型,又根据Cl-、SO42-、Mg2+、Na+之间的关系计算得出,主要为重碳酸钠型和硫酸钠型水,矿化度介于138～1145 mg/L之间,平均约580. 43 mg/L,水质中重金属铅、镉及挥发酚、pH超标。土壤分析结果显示区内的汞含量基本都超标;土污染1、4的镉元素含量超标;土污染1的镉、汞、砷、铅、锌值与其他样品相比,都表现为高值超出标准值,说明贺家梁-范家梁一带土污染较为严重。
In the "Geological and Hydraulic Ring 1 : 25,000 geological maps of the "General Survey of Majialiang-House Ping Exploration Area in the Fogang-Permian Coalfield Fugu Mine Area,Shanbei,Shaanxi Province",some wells and springs around Fuguha Town The reservoir and soil were sampled and analyzed. A total of 10 water samples were collected,including 4 waters quality briefly analysis,4 waters quality environmental analysis,2 waters quality detailed analysis,and 4 soil samples. The results show that the water quality in this area is mostlyCO32-·HCO3-·SO42--Na+·Ca2 +·Mg2 +type,and it is calculated according to the relationship betweenCl-、SO42-、Mg2 +and Na+,mainly for sodium bicarbonate type and Sodium sulphate type water,the degree of mineralization is between 138 ～ 1 145 mg/L,an average of about 580. 43 mg/L,heavy metal lead,cadmium and volatile phenol,PH exceeded the standard. The results of soil analysis showed that the mercury content in the area was basically exceeded; the cadmium content of soil pollution 1 and 4 exceeded the standard; the cadmium,mercury,arsenic,lead and zinc values of soil pollution 1 were higher than other samples. The standard value indicates that the soil pollution in Hejialiang-Fanjialiang area is more serious.
