Nitrogen oxides emissions

Nitric oxide (NO) and nitrogen dioxide (NO2) are together referred to as nitrogen oxides (NOX). Combustion of fossil fuels is by far the dominant source of NOX emissions. The emissions are not dependent solely on the amount of nitrogen in the fuel but also on the air - fuel mix ratio. High temperatures and oxidation-rich conditions generally favour NOX formation in combustion.NOX contributes to acid deposition and eutrophication which in turn can lead to potential changes occurring in soil and water quality. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes and damage to forests, crops and other vegetation. Eutrophication can lead to severe reductions in water quality with subsequent impacts including decreased biodiversity, changes in species composition and dominance, and toxicity effects.
