The analysis of the data of a three months long measurement campaign, which took place in 2015 and is now published in scientific reports, shows two main sources for nitrogen oxide concentrations. (3) a lack of a multi-pollutant, multi-medium approach that accounts for the nitrogen cascade considering these limitations, this analysis recommends that the international community develop a new global framework convention to combat reactive nitrogen. Many countries have set limits for the major pollutants released by burning fossil fuels such as carbon dioxide, sulphur oxides, nitrogen oxides and particulates simply running the plant under optimum conditions helps reduce pollutant levels but expensive control equipment is often also needed. Analysis, the bart determination must take into consideration the technology available, the costs of compliance, the energy and nonair quality environmental impacts of compliance, any pollution control equipment in use at the source, the remaining useful life of the source, and the degree of.
