“…The concentration of the lead was found to be 2 to 16 times higher comparing to its desirable limit (0.05mg/L) except site HK1 where lead was within a range. One of the major sources of lead is industrial effluent discharged in river water without any prior treatment or improper treatment [28]. The high concentration of lead in river water can damage the central nervous system, kidneys and blood system [29].…”

Water quality of Himalayan rivers has been steadily deteriorating over several decades due to anthropogenic activities, dumping of treated or untreated effluents, poor structured sewerage and drainage system, etc. In the present study, the water quality of five important rivers namely, Gola, Kosi, Ramganga, Saryu and Lohawati rivers were investigated which flow through the different districts of Kumaun region of Uttarakhand Himalaya. The water of all these rivers serves as the major source for drinking and irrigation purposes in these districts of the Kumaun region of Uttarakhand. River water samples collected in premonsoon and post-monsoon seasons of the years 2011 and 2012 were analyzed for various water quality characteristics. Statistical analyses indicate positive correlation among most of the chemical parameters. Piper diagram illustrates that all the water samples fall in Ca-Mg-HCO 3 hydrochemical facies, Moreover, the suitability of water for drinking purposes determined by water quality index indicated that river water in both the seasons is unsuitable. Irrigation water quality of all the river water was found suitable during both the seasons according to the result of sodium adsorption ratio, sodium percentage and residual sodium carbonate. The present study revealed that major factors contributing to deterioration of water quality of all the rivers might be eutrophication, tourism, anthropogenic and geogenic processes. Therefore, to restore the vitality and water quality of all these rivers, proper water resource planning programme should be developed.

“…On the contrary, higher metal concentrations observed during the monsoon season at few locations might be due to the mixing of more polluted water with less contaminated water during the rainy season. This might be contributed by the sewage overflows and runoff from agricultural and dumping sites wastes in the vicinity [37].…”

Health risk assessment of the exposure of heavy metal contamination in surface water of lower Sindh, Pakistan

In developing countries like Pakistan, there is a lack of implementation of the environmental laws to manage discharges of untreated effluents, loaded with heavy metals, into freshwater. To evaluate the potential human health impacts from exposure to such polluted water, this study assessed the concentration of six heavy metals (i.e., Zn, Fe, Pb, Cu, Cd, and Mn) in the surface water in lower Sindh, Pakistan. Water samples were collected from eight locations around Kotri barrage at Indus River both during pre-monsoon and monsoon seasons to determine the temporal variations of the concentration of heavy metals. The concentrations of heavy metals were then compared with the drinking water quality guidelines of the World Health Organization (WHO). It was observed that in most cases, the concentrations of metals were significantly higher compared to WHO guidelines during the pre-monsoon period. To determine the potential human health risk associated with the exposure of heavy metals, both oral hazard index (HI oral) and dermal hazard index (HI dermal) were estimated. The results indicated that during pre-monsoon, HI oral was higher than the threshold limits at every location, while HI dermal was higher only at three locations. Nonetheless, during monsoon, these indices were within limits. It suggested that the health of the people dependent on these freshwater streams in the study area is at considerable risk. Finally, the findings of this study recommended the enforcement of the laws in its true spirit to regulate effluent discharges into these streams in order to avoid health vulnerability of millions of people.
