Anthropogenic reservoirs

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 ... 

As partly mentioned before, natural and anthropogenic induced variations of the atmospheric C02 concentration and of the 14C/ 12C and 13C/12C ratios have been observed. For a quantitative discussion of these variations in relation to possible causes, models for the carbon cycle dynamics have been developed [21-25]. Compared to the noble gas radioisotopes 39Ar and 81Kr, for which we only have to consider a well mixed atmospheric reservoir, we have a much more complicated system for 14C. The C02 in the atmosphere exchanges with the carbon in the biosphere and with the... 

The generalized evidences on the increase of antibiotic resistance, allied with the development of analytical methods and genome exploring tools, motivated numerous studies on the environmental pollution produced by antimicrobials and other anthropogenic substances or on the diversity and distribution of antibiotic resistance genes (e.g. [3, 10, 26, 32]). Overall, these studies showed the complexity of antibiotic resistance dissemination in the environment. For instance, it was revealed that (1) not only bacterial pathogens but, very often environmental bacteria are important reservoirs of antibiotic resistance (2) antibiotic resistance may have a... 

In remote reservoirs not affected by anthropogenic pollution, particle trapping can reduce the available nutrients. In the Canadian Rocky Mountains, fertihzer has been added to lakes and rivers in the form of liquid ammonium polyphosphate with the goal to stabihze nutrient concentration at historical levels [5].
