Through human (industrial) activity, they can be mobilized, leached and reallocated, and often accumulate to concentrations that pose a threat to plant and animal life. Human activities include mining, refining, combustion of fossil fuel, and metallurgy, and they share the atmosphere among others as a common path of emission . When emitted into the air, they are mostly adsorbed to particles and can thus be subject to dry and wet deposition following atmospheric transport over short and long distances . reported that dry deposition contributes significantly within shorter distances of ca. 15 km from an anthropogenic source such as a smelter, whereas wet deposition is the dominant process controlling the deposition of TEs beyond 15 km of the source. Depending on weather, ca. 50% of all emissions are available for long-range atmospheric transport (LRAT) of hundreds to thousands of kilometers (ca. 5.000 km under average weather conditions).
