How destructive is acid rain? present evaluations range broadly, partly simply because for each proposed hyperlink among acid rain and hostile environmental results another clarification according to different phenomena may be or has been proposed, and in lots of situations can't be quite simply disregarded. the explicit parts addressed during this quantity comprise the emissions of sulfur and nitrogen oxides, precipitation chemistry, atmospheric sulfates and visibility, floor water chemistry, sediment chemistry and abundance of diatom taxa, fish populations, and woodland productiveness. The booklet then attracts conclusions in regards to the acid deposition-phenomenon courting, settling on phenomena that are at once acid deposition-caused and suggesting others it seems that because of human actions unrelated to acid deposition.

There are many differences in the properties and biological action of the compounds of the two elements, and there are differences in the types of transformations they undergo in the environment. , weathering) and microbial transformations strongly affect the sulfur cycle. There is a larger pool of endogenous nitrogen than of sulfur in organisms, and larger amounts of nitrogen than sulfur are required for plant growth. The two nutrients are closely related, so that addition of one element to an ecosystem allows greater biological utilization of the other (Turner and Lambert 1980).
