The study focuses on the analysis of trace metals in drinking water from Ganderbal and Budgam districts Jammu Kashmir. We have used high-resolution inductively-coupled plasma mass spectrometry (HR-ICP-MS) to measure concentrations 31 samples. measured were then compared with permissible limits set by United States Environmental Protection Agency (USEPA), Bureau Indian Standards (BIS), World Health Organization (WHO). results indicate that arithmetic mean several elements, including aluminum (Al = 781), chromium (Cr 139), manganese (Mn 41.86), nickel (Ni 25.89), molybdenum (Mo 1.30), cadmium (Cd 36.86), mercury (Hg 67.65), µg l−1 found higher than their respective limits. On other hand, such as beryllium (Be 0.14), boron (B 32.72), iron (Fe 233), cobalt (Co 1.79), copper (Cu 10.71), arsenic (As 0.93), selenium (Se 3.13), strontium (Sr 257), zinc (Zn 43), antimony (Sb 1.44), barium (Ba 28.56), gold (Au 0.91), lead (Pb 0.91) l−1, had below recommended USEPA, BIS, WHO. To assess toxicity heavy area, we calculated Heavy Metal Toxicity Load (HMTL) for each metal. Based these calculations, concluded only (Cd) (Cr) need be removed ensure safety. also conducted a health risk assessment children adults based metals. considered ingestion dermal contact routes exposure. Hazard Index (HI), which indicates non-carcinogenic effects, exceeded unity one element, (Cd), adult groups. This suggests potential risks associated contact.

Understanding the implementation of environmental regulation is essential to design policy. The impact water pollution on mortality was examined in this study using a spatial regression discontinuity (RD) based China's quality monitoring system. Because readings are important political promotion officials and stations only capture from upstream, local governments have an incentive combat not downstream. Exploring stringency regulations by linking 2010 census microdata with station location data China, we found that households immediately upstream faced more than 11% reduction household compared downstream station. Strict supervision had greater effect rural households. difference between even for high automatic technology. results improve our understanding health effects regulation, as well policies under centralized
