摘要

这项工作分析了保加利亚南部马里察河的三条支流中营养成分和微量金属及类金属含量的变化,这些支流的集水区受到采矿和农业活动的影响。输入数据包括2015-2018年环保局提供的14个化学水质参数(n - nh4、n - no3、n - no2、N-tot、P-tot、p - po4、Al、As、Fe、Cu、Mn、Ni、Pb和Zn)的信息。本文采用文献记录的两种方法——重金属污染指数(HPI)和CCME水质指数来确定河流水质的污染状况。基于CCME WQI的结果将水质评为“差”(WQI值在31.2至39.9之间)。一些金属(Al, Cu, Mn和Zn)的HPI评分达到了超过100的污染临界值,这表明水在这些变量上受到严重污染。综上所述,由于水体中含有大量的营养物质、类金属和微量金属,因此不适合安全饮用、农业和家庭使用。

Surface water pollution with nutrient components, trace metals and metalloidsin agricultural and mining-affected river catchments: A case study for three tributaries of the Maritsa River, Southern Bulgaria
This work analyses changes in the content of nutrient components and trace metals and metalloids at three tributaries of the Maritsa River flowing in Southern Bulgaria with catchments affected by mining and agricultural activities. Input data includes information about 14 chemical water quality parameters (N-NH 4 , N-NO 3 , N-NO 2 , N-tot, P-tot, P-PO 4 , Al, As, Fe, Cu, Mn, Ni, Pb, and Zn) obtained from the Executive Environment Agency for the period 2015-2018. Two documented methods were used in this work to determine the pollution status of river waters-Heavy metal pollution index (HPI) and CCME Water Quality Index. The results based on the CCME WQI ranked water quality as "Poor" (WQI values range from 31.2 to 39.9). The HPI ratings achieve scores exceeding the critical pollution value of 100 for some of the metals (Al, Cu, Mn, and Zn), which indicates that water is seriously polluted concerning those variables. Therefore, it can be summarized that the river waters are not appropriate for safe drinking , agriculture, and household use because of significant nutrient and metalloids and trace metalscon-tamination.
