1. Urban GeochemistryUrban geochemistry is a unique disciplineand separate from the environmental geochemistry and of other land use and generalgeochemistry due to very high concentration of human and intensity ofindustrial and human activity. As said by (Thornton, 1991) “This subjectis objective anxiety with the tricky interplays and connection inter chemicalelement and their mixes in the urban habitat, the effect of different timepeople and manufacture activities on these, and the influences or impacts ofgeochemical parameters in urban terrain on plant, cattle and human health”urban areas show difficult to intelligibility geochemical case and fluxes bygeochemist. The term urban geochemistry was used by lain Thornton in the early1990s.
chemical spread arising can be influence from urbanization on both environmentand human health. Urban geochemistry gives important information on the chemicalcomposition of ecosystems and environments that solidarity large population andare critical to human health (LyonsHarmon, 2012)replacement of the vegetation and forests and lands occur thatchange nature geochemical fluxes and make urban zones or lands unlike otherenvironment place due to need dweller and development urban and humanmanipulation of landscape, and urbanization change watersheds due to effects ofphysical, chemical, hydrological, ecological. Such as housing and otherbuilding and making road, they can reduce infiltration and surface storage ofprecipitation that increase surface water runoff and less water infiltrate intosoil and finally less evaporite occur and this case large influence on waterquality and soil involve to combination of toxic and bad elements, withouturbanization water can more infiltrate into soil in order of more evaporiteoccur hence do not large change on water quality and chemical elements fromsoil and partitioning of the chemical from soil to stream and lake.
2. Anthropogenic resources of pollutionAnthropogenic is the human impact onenvironment specially in contamination of environment and soil and etc., thatquantities of metals increasing within environment due to anthropogenicactivities, and metals can enter into human body in way contaminated food ordrinking or due to air. Anthropogenic source of pollutants depends on thepopulation and different human activities to improve the quality of life. Anthropogenicactivities such as metalliferous mining (As, Cd, Cu, Ni, Pb, Zn), smelters (As,Cd, Pb) can be source for heavy metals that contaminate soil (AncaMariaMoldoveanu, 2012).
Other anthropogenic source that release a variety of toxicpollutant into the environment such as automobile emissions, agricultural activity,industrial, in agricultural land excessive use of Pesticides, fertilizers,herbicides and animal wastes, some elements (N, Ph, k) use to growth plant thatcontinuous use these elements make toxic condition for human or in high level. Sources of nitrogen from human activities, as electric powergeneration, industry, transportation and agriculture, can edit balance ofnitrogen in the environment. Heavymetals can be to high mobility in the soil from anthropogenic sources.Consuming Hydrocarbon for more purpose caused of dangerous case as pollute airand contaminate soil, water. The quality of ground water may be impacted bynaturally processes and human activities, that may be involve some chemicalelements and next in operation on soil may be soil separate those element fromground water. The major activity of human is smelt metals and mining of metals requireto life and daily function that impact on environment.
