Activities anthropogenic

Both contamination and pollution entail the perturbation of the natural state of the environment by anthropogenic activity. The two terms are distinguishable by the severity of the effect pollution induces the loss of potential resources. Additionally, a clear cause-effect relationship must be established for a substance to be classified as a pollutant towards a particular organism. 

If, as a result of anthropogenic activities, nitrogen is being removed from the atmospheric reservoir (as N2) to the oceanic reservoir (as N03 ), how long would it take to detect this change Is this a thermodynamically favorable process ...

Lead is dispersed throughout the environment primarily as the result of anthropogenic activities. Environmental fate processes may transform one lead compound to another however, lead is not degraded and is still available for human exposure, even though the compounds containing it vary enormously.

Zinc ligands are soluble in neutral and acidic solutions, so that zinc is readily transported in most natural waters (USEPA 1980, 1987), but zinc oxide, the compound most commonly used in industry, has a low solubility in most solvents (Elinder 1986). Zinc mobility in aquatic ecosystems is a function of the composition of suspended and bed sediments, dissolved and particulate iron and manganese concentrations, pH, salinity, concentrations of complexing ligands, and the concentration of zinc (USEPA 1980). In freshwater, zinc is most soluble at low pH and low alkalinity 10 mg Zn/L of solution at pH 6 that declines to 6.5 at pH 7, 0.65 at pH 8, and 0.01 mg/L at pH 9 (Spear 1981). Dissolved zinc rarely exceeds 40 pg/L in Canadian rivers and lakes higher concentrations are usually associated with zinc-enriched ore deposits and anthropogenic activities. Marine... 

Measurable PCP concentrations in field collections of living and nonliving materials over widespread geographic areas are almost certainly due to anthropogenic activities, especially to the use of the chemical as a wood preservative.
