Urban Geochemistry

Urban geochemistry is a unique discipline
and separate from the environmental geochemistry and of other land use and general
geochemistry due to very high concentration of human and intensity of
industrial and human activity. As said by (Thornton, 1991) “This subject
is objective anxiety with the tricky interplays and connection inter chemical
element and their mixes in the urban habitat, the effect of different time
people and manufacture activities on these, and the influences or impacts of
geochemical parameters in urban terrain on plant, cattle and human health”
urban areas show difficult to intelligibility geochemical case and fluxes by
geochemist. The term urban geochemistry was used by lain Thornton in the early
1990s. chemical spread arising can be influence from urbanization on both environment
and human health. Urban geochemistry gives important information on the chemical
composition of ecosystems and environments that solidarity large population and
are critical to human health (LyonsHarmon,
2012)replacement of the vegetation and forests and lands occur that
change nature geochemical fluxes and make urban zones or lands unlike other
environment place due to need dweller and development urban and human
manipulation of landscape, and urbanization change watersheds due to effects of
physical, chemical, hydrological, ecological. Such as housing and other
building and making road, they can reduce infiltration and surface storage of
precipitation that increase surface water runoff and less water infiltrate into
soil and finally less evaporite occur and this case large influence on water
quality and soil involve to combination of toxic and bad elements, without
urbanization water can more infiltrate into soil in order of more evaporite
occur hence do not large change on water quality and chemical elements from
soil and partitioning of the chemical from soil to stream and lake.

Anthropogenic resources of pollution

Anthropogenic is the human impact on
environment specially in contamination of environment and soil and etc., that
quantities of metals increasing within environment due to anthropogenic
activities, and metals can enter into human body in way contaminated food or
drinking or due to air. Anthropogenic source of pollutants depends on the
population and different human activities to improve the quality of life. Anthropogenic
activities 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 toxic
pollutant 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 that
continuous use these elements make toxic condition for human or in high level. Sources of nitrogen from human activities, as electric power
generation, industry, transportation and agriculture, can edit balance of
nitrogen in the environment.  Heavy
metals can be to high mobility in the soil from anthropogenic sources.
Consuming Hydrocarbon for more purpose caused of dangerous case as pollute air
and contaminate soil, water. The quality of ground water may be impacted by
naturally processes and human activities, that may be involve some chemical
elements and next in operation on soil may be soil separate those element from
ground water. The major activity of human is smelt metals and mining of metals require
to life and daily function that impact on environment.
