In this study, we assess the drinking water quality of Jhelum city. Two hundred and ninety-two drinking water samples were randomly collected in the study area. These samples were chemically analyzed for three key toxic (in excess) elements such as pH, total dissolved solids (TDS), and calcium. Geostatistical techniques such as variogram and kriging were used to investigate the spatial variations of these minerals across the city. The spatial structure for each element was found to be anisotropic, and thus, anisotropic variograms were used. The kriging predictions revealed significant concentrations of the above-stated elements at some locations in the study area. While comparing with the World Health Organization, United States Environmental Protection Agency, and Pakistan Environmental Protection Agency standards, the water samples were found to be unsatisfactory for drinking. We conclude that the drinking water in this region is of poor quality and needs proper treatment to make it palatable. 相似文献

ABSTRACTThe link between environmental frames and policy outcomes in China is explored. Environmental nongovernment organizations’ (ENGOs) issue interpretation and presentation affect environmental policy changes. The notion of ‘frame alignment’ is introduced, and it is argued that it can serve to link ENGOs’ advocacy needs and frame resonance among different stakeholders, thus successfully promoting advocacy. Based on in-depth interviews and analysis of news reports over a span of 10 years, it is found that where ENGOs are able to align their issue frames with those of the central state and media, the resulting frame resonance smooths policy change. In contrast, where ENGOs adopt conflict frames critical of state authorities, the absence of alignment leads to a slim chance of policy change. The findings shed light on why some ENGOs successfully create linkage and achieve their desired outcomes while others fail to do so. 相似文献
