“…Consequently, the NO2 --N concentration in the water body increases [31]. Moreover, high nitrite levels in water depend on agricultural fertilizer use and untreated wastewater discharge [8]. Organisms living in nitritecontaminated aquatic environments can experience oxidative stress in gills and serum, negatively affecting the growth and development of aquatic organisms [34].…”

“…In Vietnam, the water quality index (WQI) is considered a useful and widely used tool in the environmental monitoring program to optimize monitoring data. The WQI index is calculated according to a mathematical formula that gathers many typical environmental parameters and represents a single number, allowing one to determine the environmental quality in a specific space and the suitability of the environment for each water use purpose [6][7][8]. Even so, the presence of pollutants in water can also harm water users and aquatic organisms [9,10].…”

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.
