“…Potassium ions in groundwater often come from orthoclase and muscovite minerals present in granite, and from pollution sources such as chemical fertilizer and domestic effluents. Chloride (Cl − ) may be derived from pollution sources such as industrial and domestic effluents, fertilizers and septic tanks (Bohlke and Horan 2000;Edmunds et al 2003;Negrel and Pauwels 2003;Petelet-Giraud et al 2003;Widory et al 2004; Valdes et al 2007), and from natural sources such as rainfall, the dissolution of fluid inclusions and chloridebearing minerals (Negrel and Roy 1998;Negrel 1999). Groundwater contamination due to nitrate has been a concern for some time.…”

Although water constitutes 71% of the earth's surface, only 0.3% of it is available as fresh water for human use. Moreover, the quality of fresh water in ground and surface systems is of great concern, as potable water needs to have appropriate mineral content. Ground and surface water quality in rural and urban environments is affected by both natural processes and anthropogenic influences. Because of this, water is becoming scarcer as the population increases across the world. Natural processes leading to changes in water quality include weathering of rocks, evapotranspiration, depositions due to wind, leaching from soil, run-off due to hydrological factors, and biological processes in the aquatic environment. These natural processes cause changes in the pH and alkalinity of the water, and also phosphorus loading, increase in fluoride content and high concentrations of sulphates. Anthropogenic factors affecting water quality include impacts due to agriculture, use of fertilizers, manures and pesticides, animal husbandry activities, inefficient irrigation practices, deforestation of woods, aquaculture, pollution due to industrial effluents and domestic sewage, mining, and recreational activities. These anthropogenic influences cause elevated concentrations of heavy metals, mercury, coliforms and nutrient loads. This paper studies the effects of natural processes and human influences in rural and urban aquatic systems. Pollution due to environmental parameters such as heavy metal pollution, heavy metals and bacterial and pathogenic contamination of both urban and rural areas is discussed in detail.

“…Co-incidentally, this is also a value that would indicate food sourced on marine carbonates such as chalks and limestone , Montgomery et al 2007a). If such a value were obtained from the inhabitants of Skye, it could be attributed to the Durness limestone valley to the south of the Cuillins which is sheltered and fertile Transported atmospheric dust and aerosols may be a major consideration when working in arid or continental regions (Andersson et al 1990, Benson et al 2008, Negrel and Roy 1998, but is less of a problem in temperate, maritime islands such as the British Isles where rainfall is the major source of atmospheric deposition. The Isle of Skye, like much of the western Atlantic seaboard of Britain, has high rainfall throughout the year and increasing rainfall has been shown to gradually shift the ratios of strontium available to plants away from the rock toward that of rainwater ( Figure 6) (Capo et al 1998, Raiber et al 2009), which in coastal regions is close to seawater, i.e.…”

AbstractStrontium isotopes are a powerful tool which provide information about provenance directly from the tissues of humans rather than the grave context and burial goods.Geographical variation in strontium isotopes is primarily controlled by the underlying geology but there are many other factors that need to be considered before migratory individuals can be identified. Consequently, despite many studies which have shown that the method works well, it is clear that much remains to be clarified and it will not work for every question or in every place. It rests on the assumption that people were sourcing their food locally and that there is a measurable strontium isotope difference between the place the person migrated from and the place they migrated to. As migrants may deliberately seek out familiar soil types and terrains in their new homeland, some questions surrounding major migration events may prove intractable for this technique. Other factors that can create heterogeneity or homogeneity leading to false positives or false negatives, such as human choices or coastal subsistence, are explored and the metabolism of strontium into human tooth enamel is discussed.Several models of land use choices by humans are presented to highlight the subtleties inherent in the isotope data and these are used to interpret archaeological human isotope ratios from three studies.

“…The concentration of Ca 2+ was higher than that observed in the regional background sites Maolan, Leigongshan, and Longfengshan, but lower than that of cities. Further, we compared our results with worldwide monitored data, revealing that the ionic concentrations (such as SO 4 2-) of the precipitation in our study area were higher than that of reference cities in Europe (Négrel and Roy, 1998), North America (Ito et al, 2002), and Southeast Asia (Okuda et al, 2005). However, the NO 3 -concentration was much lower, compared to these cities.…”
