“…In comparison to the rainy season, the mean concentrations of heavy metals such as Cu, Zn, As, Ni, and Hg in the river water was detected at a slightly higher in the dry season, while those of Pb, Cd, and Cr in the river water were lower in the dry season (Table 1). Although these differences were not statistically significant, this pattern of heavy metal concentration is similar to a recent study on the occurrences of heavy metals in a confluence of an urban canal and a mainstream of the Saigon River (Nguyen et al 2020). Also, our results showed that the majority of the tested heavy metals such as Cu, Pb, Zn, As, Cr, and Ni were found slightly higher in the water samples collected at the industrial and residential areas compared to the agricultural and less impacted areas.…”

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, PO4-P, NH4-N, NO3-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.

“…Considering heavy metals, Zinc and Lead were the metals with most contamination with pollution levels higher in the dry season compared to the rainy season though not in the same trend. In comparison to the results obtained on the Saigon River by [38], the mean concentrations of heavy metals such as Cu, Zn, and Hg in the water body was detected at a slightly higher level in the dry season, while that of Pb in the river water were lower in the dry season. In addition of these differences being statistically significant, this pattern of heavy metal concentration is similar to a study on the occurrences of heavy metals in the Journal of Water Resource and Protection Kumba River.…”

Anthropogenic activities have contributed to pollution of water bodies through deposition of diverse pollutants amongst which are heavy metals. These pollutants, which at times are above the maximum concentration levels recommended, are detrimental to the quality of the water, soil and crops (plant) with subsequent human health risks. The objective of the work was to evaluate the impacts of human-based activities on the heavy metal properties of surface water with focus on the Kumba River basin. Field observations, interviews, field measurements and laboratory analyses of different water samples enabled us to collect the different data. The results show four main human-based activities within the river basin (agriculture, livestock production, domestic waste disposal and carwash activities) that pollute surface water. Approximately 20.61 tons of nitrogen and phosphorus from agricultural activities, 156.48 tons of animal wastes, 2517.5 tons of domestic wastes and 1.52 tons of detergent from carwash activities were deposited into the river each year. A highly significant difference at 1% was observed between the upstream and downstream heavy metal loads in four of the five heavy metals tested except for copper that was not significant. Lead concentrations were highest in all the activities with an average of 2.4 mg•L −1 representing 57.81%, followed by zinc with 1.596 mg•L −1 (38.45%) and manganese with 0.155 mg•L −1 (3.74%) for the different anthropogenic activities thus indicating that these activities highly lead to pollution of the Kumba River water. The level of zinc and manganese was significantly influenced at ρ < 005 by anthropogenic activities though generally the variations were in the order: carwash (3.196 mg•L −1 ) < domestic waste disposal (3.347 mg•L −1 ) < agriculture (4.172 mg•L −1 ) < livestock (4.886 mg•L −1 ) respectively and leading to a total of 14.04 tons of heavy metal pollutants deposited each day.

“…The sources of heavy metal and water chemical pollution in rivers are related to regional geology, precipitation runoff, contaminated sediment relase, atmospheric deposition, and human activities [ 12 , 13 , 14 , 15 , 16 , 17 ]. Currently, methods such as correlation analysis, redundancy analysis (RDA), and principal component analysis (PCA) are widely used to analyze the sources of heavy metals in surface water [ 18 , 19 , 20 ]. Each river has its own characteristics due to differences in geography, climate, and the degree of urbanization.…”

Three high-frequency sampling and monitoring experiments were performed at the Lutang and Luowei transects of the Liujiang River entrance and at the southeast exit of the Liuzhou during 2019 for the purpose of assessing physico-chemical variables and human health hazards of water heavy metals in different rainfall processes. There were significant seasonal variations in concentrations of 11 heavy metals and most variables showed higher levels during the dry season. The distribution of heavy metals in the Liuzhou area varied significantly by region. Pollution source analysis indicated distinct seasons of wetness and dryness. The dry season is dominated by anthropogenic activities, while the wet season is dominated by natural processes. The results of hazard quotient (HQ) and carcinogenic risk (CR) analysis showed that the health risk of non-carcinogenic heavy metals in the wet season is slightly higher than that in the dry season. Seasonal changes in carcinogenic risk are the opposite; this is due to the combined influence of natural and human activities on the concentration of heavy metals in the river. Among them, Al was the most important pollutant causing non-carcinogenic, with As being a significant contributor to carcinogenic health risk. Spatially, the downstream Luowei transect has a high health risk in both the dry and rainy seasons, probably due to the fact that the Luowei transect is located within a major industrial area in the study area. There are some input points for industrial effluent discharge in the area. Therefore, high-frequency monitoring is essential to analyze and reduce the heavy metal concentrations in the Liujiang River during dry and wet seasons in order to protect the health of the residents in the area.
