“…The desirable limit of Zn in drinking water is specified as 3 ppm (WHO, 2008). Several studies suggest that excessive amount of Zn (3-5 ppm) can cause neuron death and toxicity resulting in diarrhea, vomiting and may appear opalescent and develop a greasy film on boiling vessel and produce bitter taste (Pizarro et al, 1999;WHO, 2006;Atapour, 2012). The analysis of surface water revealed (2004) and Sehar et al (2011) have reported that Mn exposure rivets both psychiatric indication and Parkinsonism skin texture.…”

Several textile and bleaching industries in the city of Karur, discharge their effluent and was mixed with municipal sewage let into the river Amaravathi at different discharge points. Concentration of trace elements (Cd, Pb, and Ni) exceeded their permissible limits (.003, .01, and .02 ppm, respectively) prescribed by the World Health Organization. C d (Degree of contamination) and HEI (Heavy metal evaluation index) values were calculated, C d value of 50% samples have <4 indicates low degree of contamination and for groundwater samples only one-third samples were observed in low pollution and the remaining samples fall in medium to high degree of pollution. HEI value indicates that the average value (12.510, 12.514, and 12.164) of both the samples were above the low pollution range. Good positive correlations observed for Mn, Ni, and Fe with r value from .522 to .913. Principal component analysis (PCA) was used to analyze the data and to identify possible sources of these heavy metals. Three factors for surface water and two factors for groundwater were extracted, where the first three factors account for approximately 58.7% of the total variance of the data-set. The results of groundwater samples show that the factor 1 and 2 accounted for 74.508 and 71.261% of the total variance. The data thus obtained are a sign of anthropogenic and mineral source for these elements in river and groundwater. The spatial distribution map based on ordinary kriging showed that elevated concentrations of heavy metals were located in the upper and down streams of the Amaravathi River basin. The dominance of heavy metals in groundwater and surface water of the Amaravathi river followed the sequence as

“…However, the types and severity of toxic effects are not proportional to the concentrations of toxic elements. Some toxic elements with low concentration exhibit much more significant health effect than others with high concentration (Adel et al, 2016;Çelebi et al, 2014;Saha and Zaman, 2013;Atapour 2012;Malakootian et al, 2014). The adverse effects of toxic elements may also vary depending on the physiological aspects of human health.…”

Tap water is the sole source of water in urban cities but gradually being polluted by potentially toxic elements due to unplanned urbanization. The south Asian megacity, Dhaka (capital of Bangladesh) encounters drastic water pollution resulting mainly from anthropogenic differential factors. Consumption of such polluted water distributed to residents by pipelines can trigger health risks. Therefore, this study investigated the public health vulnerability associated with dissolved metal(oid)s in tap water collected across Dhaka city. The concentrations of Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Hg and Pb in measured tap water ranged from 8-156, 7–73, 400-20100, 12–110, 7-101, 12–136, 12–908, 0.03–9.75, 1–5, 0.22–1.30, and 8-118 µg/L, respectively. Among the observed elements, Pb, Cr, and Fe concentrations in 18%, 26%, and 75% of sampling sites, respectively, exceeded the standard guideline criteria of Bangladesh. Entropy-based water quality index demonstrated that ~ 12% of sampling sites possessed water unsuitable for drinking and other household works. The dominant sources of water pollution in this region are industrial effluents and domestic sewage. Both non-carcinogenic and carcinogenic health risks are invoked mostly from ingestion of Co and Pb. Regular consumption of this tap water without further pretreatment may result in detrimental health consequences to both children and adults due to the physiological accumulation of toxic elements over time. This study highlighted a comprehensive scenario of the potentially toxic elements in the tap water of Dhaka city, which will allow policymakers to take adequate measures for sustainable water quality management.

“…In recent years, estimation of carcinogenic and non-carcinogenic health risks (e.g., heart and kidney diseases) has become important, because many clinical symptoms have been observed at concentrations lower than the prescribed limits (Adel et al, 2016;Çelebi et al, 2014;Saha and Zaman, 2013), while in some cases, exceedance of prescribed levels have not caused human health problems. However, several studies have reported metal content in drinking waters in Iran (Atapour, 2012;Malakootian et al, 2014;Pirsaheb et al, 2013a), but those studies are only limited to a comparison of metal concentrations with respective standard limits.…”
