Affect of gaseous ammonia and oxides of nitrogen on plant growth.
Full title: Gaseous ammonia and oxides of nitrogen can lead to both a stimulation and a reduction in plant growth. Using examples of effects at both the cellular and whole plant level, discuss the relative merits/disadvantages of life in a polluted environment.
Introduction: Major sources for ammonia (NH3) emissions are connected with areas of intensive agriculture and high rates of fertilizer manufacture and application. Fertiliser is often applied as ammonium or urea.
