Abstract

The study was carried out to assess the pollution, impact, and risk level to the surface water environment of pollutants in the water bodies of Soc Trang province, Vietnam. The parameters for evaluating surface water quality and risks included temperature, pH, TSS, DO, BOD, COD, NH4+-N, NO2--N, NO3--N, PO43--P, Cl-, Fet, and coliform. Surface water samples were collected at 35 locations with a frequency of six times (February, April, June, August, October, and December) in 2022. The water quality index (WQI), impact and risk level (risk quotient or RQ, RQ-F), correlation analysis, and principal component analysis (PCA) were utilized in the study. The results show that the surface water has been seriously polluted due to organic matter, nutrients, microorganisms, iron, and salinity. The values of WQI in the dry and rainy seasons fluctuated between bad and very good, indicating that surface water quality is suitable for water transport and other purposes with higher quality requirements. TSS, COD, Fet and coliform have a high impact and risk for the environment in this study area. There were no environmental impacts and risks to NO3--N. Locations with many high-risk pollutants were mainly distributed in residential and coastal areas. The significant negative correlation between the WQI and RQ indicated that the lower the WQI, the higher the environmental risk. The PCA results show that at least six polluting sources affected water quality and caused environmental risks. The results of this study contribute essential and valuable information for improving water quality in the study area through the assessment of environmental impacts and risks. Doi: 10.28991/CEJ-2023-09-08-03 Full Text: PDF
地表水水体污染物污染及风险等级评价
本研究旨在评估越南Soc Trang省水体中污染物对地表水环境的污染、影响和风险水平。地表水水质及风险评价参数包括温度、pH、TSS、DO、BOD、COD、NH4+-N、NO2——N、NO3——N、PO43——P、Cl-、Fet和大肠菌群。2022年在35个地点采集地表水样本,采样频率为6次(2月、4月、6月、8月、10月和12月)。采用水质指数(WQI)、影响和风险水平(风险商RQ, RQ- f)、相关分析和主成分分析(PCA)进行研究。结果表明,由于有机质、营养物、微生物、铁和盐度的影响,地表水受到了严重的污染。旱季和雨季WQI值在差和很好之间波动,表明地表水水质适合输水等对水质要求较高的用途。TSS、COD、Fet和大肠菌群对研究区环境具有较高的影响和风险。对NO3—N没有环境影响和风险。高风险污染物较多的地点主要分布在居民区和沿海地区。WQI与RQ呈显著负相关,表明WQI越低,环境风险越高。主成分分析结果表明,至少有6种污染源影响水质并造成环境风险。本研究结果为通过环境影响和风险评估来改善研究区域的水质提供了重要和有价值的信息。Doi: 10.28991/CEJ-2023-09-08-03全文:PDF
