Zn, Pb, As mainly originated from anthropogenic source while the other metals are geogenic.
It was also found that sites close to large anthropogenic point sources exhibited relatively higher emission fluxes, indicating potential of Hg reemissions from historical deposited Hg from anthropogenic sources.
Cl− concentration apart from coastal region derived from Anthropogenic sources include fertilizer, human and animal waste and industrial applications.
Additionally, the lifetime of O3 in winter is long enough to allow its accumulation once produced from the precursors emitted from anthropogenic sources (Fenneteaux et al. 1999; Liu et al. 1987).
In addition, to rock leaching due to some external effects, these effluents discharge from various anthropogenic sources such as power plants, chemical manufacturing, painting, mining, metallurgy, electroplating, and many other industries [13, 14, 15].
To the extent that Pb and Cu are not major constituents regarding the mineralogy of the Bibiani area (Quarshie et al. 2011), presumably, the contamination from these two metals were from anthropogenic sources.
Throughout the 1990s, the U.S. Environmental Protection Agency EPAA) made steady progress in reducing mercury emissions from anthropogenic sources, especially from power plants, which account for 41% of anthropogenic emissions.
Contaminants in surface and groundwater may come from anthropogenic sources, runoff from agricultural activities (Chapin et al. 2005), or controlled or uncontrolled discharges from sewage treatment facilities or leaking landfill sites (Kolpin et al. 2002).
Nriagu (1989) and Finley et al. (2009) estimated that the amount of lead (plus other trace metals) and mercury, respectively, from fires were comparable to emissions from anthropogenic sources such as industrial processes and city pollution.
Rastrineobola argentea has experienced increased mortality over the past half century from two major anthropogenic sources: predation from the introduced Nile perch and commercial fishing.
