Acid Rain

Precipitation with low pH, usually resulting from excessive sulfur or nitrogen oxides in the atmosphere. Acid rain is detrimental to both plant and animal life. It has become less common since the 1970s, when governments began to take steps to reduce the sulfur released into the air.

public health and to protect [the State's] environment, economy, and infrastructure from irreparable damage from acid deposition.'" (34) It was the Legislature's intent to not only reduce New York's contribution to acid deposition, but also "to encourage federal controls on [acid] deposition." (35)
These pollutants are also precursors for other atmospheric issues, such as acid deposition, smog, and hazardous air pollutants.
The capability of certain Eulerian models to assess the relationship between [SO.sub.2] emissions and acid deposition is the primary focus of the Acid Deposition Standard Feasibility Study Report to Congress.(147) If these models can accurately assess the relationship between emissions and deposition, the cap for [SO.sub.2] emissions under Title IV could be lowered to meet the required acid deposition standards.(148) In short, the impact of [SO.sub.2] emissions that is reflected in an acid deposition standard could be taken into account when establishing NAAQS for [SO.sub.2].(149)
Predictably, many managers and agencies responded by altering descriptions of their ongoing research projects to emphasize the links to acid deposition, even where the link was flimsy.
Certainly, environmentalists and many scientists would challenge to claim that the acid deposition problem has been solved.

The protein deposition and feed intake listed in Table 2 were used to calculate amino acid intake and amino acid deposition, and estimate thus the efficiency of utilization and the requirement per kg of weight gain of birds.
A by-product of fossil fuel combustion from automobiles, factories, coal-fired power plants, and other sources, acid rain (or more appropriately called "acid deposition" since it also includes snow, sleet, fog, clouds, and gases and particles that fall to the earth) has caused significant environmental harm.
Therefore, precipitation chemistry measurements play a critical role in defining both the level of acid deposition and the state of some important biogeochemical cycles of the earth-atmosphere system [5] .
