“…ranging from 66 to 90 and 2.0 to 26 [14,15] although the rivers are located nearby mining areas. In Nigeria (Commodore channel) and China (Houjing River), the HPI results ranged between 985 and 5995, and 100 and 230, indicating high amounts of heavy metals due to industrial (wastewaters, landfill leachate) and household activities [60,61].…”

This study aims to investigate the quality and vulnerability of surface water (Aries River catchment) in order to identify the impact of past mining activities. For this purpose, the pollution and water quality indices, Piper and Durov plots, as well vulnerability modeling maps were used. The obtained results indicate that the water samples were contaminated with As, Fe, Mn, Pb and have relatively high concentrations of SO42−, HCO3−, TDS, Ca, K, Mg and high values for the electrical conductivity. Possible sources of the high content of chemicals could be the natural processes or the inputs of the mine drainage. Generally, according to the pollution indices, which were correlated to high concentrations of heavy metals, especially with Pb, Fe and Mn, the water samples were characterized by heavy metals pollution. The water quality index classified the studied water samples into five different classes of quality, namely: unsuitable for drinking, poor, medium, good and excellent quality. Similarly, medium, high and very high vulnerability classes were observed. The Durov and Piper plots classified the waters into Mg-HCO3− and Ca-Cl− types. The past and present mining activities clearly change the water chemistry and alter the quality of the Aries River, with the water requiring specific treatments before use.

“…The kidney is the main target organ for cadmium toxicity (World Health Organization, 2017). After acute ingesting cadmium, symptoms such as abdominal pain, burning sensation, nausea, vomiting, salivation, muscle cramps, vertigo, shock, loss of consciousness, and convulsions usually appear within 15 to 30 min and may cause osteomalacia, anemia, and teeth discoloration (Charles et al, 2018;Tchounwou et al, 2012).…”

Heavy metal contamination has become a serious concern due to its toxicity not only on ecosystems but also directly on human health. The Chao Phraya River Basin is the main area important for commerce, industries, and residence in Thailand. This study aimed to evaluate the impact on human health due to heavy metal contamination and identify the relationship between land use and heavy metal contamination in the Chao Phraya River. Pearson correlation was applied to analyze the relationship between heavy metal concentration and water parameters. The results indicated that during 2009-2013, Fe concentration positively correlated to turbidity (0.640), total phosphate (0.622), suspended solids (0.542), and Ni level (0.513) in the river but negatively correlated to Zn level (-0.517) at P<0.01. From 2014 to 2018, the results revealed that Fe concentration positively correlated to turbidity (0.900), suspended solids (0.671), Mn (0.607), and Ni level (0.512) at P<0.01, and Cd concentration also positively correlated to Cr level (0.509). The results showed that human health risks in some stations in Lampang, Chiang Mai, and Sukhothai province were acceptable from 2009 to 2011 and changed to very high risk on human health from 2015 to 2018. The heavy metal pollution index was calculated and compared to land use data. The results revealed that the change from deforestation into agricultural land, especially in the Yom River area, could be the cause of the heavy metal contamination by fertilizer. All of the data was created to map for easy understanding.

The contamination of public water supply and groundwater resources is a major concern in many parts of developing nations. Polluted water poses serious health risks to humans and the environment. This research was conducted to investigate the seasonal variations of the water quality parameters in the public water supply. To assess the supply water quality in different blocks of Ambala District, hydro‐chemical analysis was conducted after a series of systematic sampling in various locations. The statistical tools for water quality indexing including water quality indexing (WQI), heavy metal pollution indexing (HMPI), pollution indexing (PI), overall pollution indexing (OPI), metal indexing (MI), and hazard indexing (HI) were used for data as well as the health hazard analysis through water pathway. Overall, 40 water samples were taken from the public water supply systems covering winter and summer seasons, and the levels of pH, total dissolved solids (TDS), EC, F−, Cl−, NO3−, SO42−, HCO3−, As, B, Cd, Co, Pb, Zn, Cr, Fe, and Mn were investigated. The weight arithmetic index method was used for WQI, and water pollution indices such as HMPI, PI, OPI, and MI were calculated using different models to check the severity of contamination. The mean hazard quotient and hazard index values calculated using the concentration levels of As, B, Cd, Co, Pb, Cr, Fe, Mn, Zn, F−, and NO3− reveal that supply water may pose a significant health risk to both adults and children that further varies with temporal and spatial changes. During both seasons, a high carcinogenic risk for both adults and children was observed in the studied area because of high levels of As, Pb, Cd, and NO3−.Practitioner Points The quality of public supply water was assessed at the selected sites of Ambala, India. High levels of NO3−, As, Cd, and Pb were observed posing a health risk to adults and children via water pathway. 95% of the samples qualified for the excellent water quality category with respect to the levels of F−, Cl−, NO3−, SO42−, HCO3−, pH, EC, and TDS. Statistical analysis (HMPI, PI, MI, OPI, HI) using different models revealed water contamination with reference to the levels of NO3−, As, Pb, Cr, Ni, and Cd. Immediate measures are needed to uphold the safety and health of the natives.
