Water quality for the surface water along the Saigon River in Ho Chi Minh City was assessed for four groups of water samples collected at the agricultural, industrial, residential, and less impacted areas. A variety of parameters indicating water quality including physicochemical parameters, nutrients, heavy metals, and antibiotic residues were measured for both the rainy and dry seasons, two main tropical seasons in HCM City using the standard methods. The results showed that the river water in the rainy season was detected with significantly higher values of turbidity, BOD5, PO-P, NH-N, NO-N; and lower values of pH, temperature, conductivity, DO, salinity, Cu, Zn, As, Ni, Hg compared to that in the dry season. Sulfamethoxazole and trimethoprim were highly detected in the industrial areas compared to the agricultural and residential areas. Multivariate analyses suggested that the industrial and residential activities were more important contributors to the pollution of the Saigon River than the agricultural activities in HCM City.
对胡志明市西贡河沿岸的地表水进行了水质评估，采集了农业、工业、住宅和受影响较小地区的四组水样。使用标准方法，在胡志明市的两个主要热带季节——雨季和旱季，对水质的各种参数进行了测量，包括理化参数、营养物质、重金属和抗生素残留。结果表明，雨季河水的浊度、BOD5、PO-P、NH-N、NO-N 显著升高，而 pH 值、温度、电导率、DO、盐度、Cu、Zn、As、Ni、Hg 则降低。磺胺甲恶唑和甲氧苄啶在工业区的检出率明显高于农业区和住宅区。多元分析表明，与农业活动相比，工业和住宅活动是胡志明市西贡河污染的更重要贡献者。
