متن کاملGlobal Assessment of Terrestrial Ecosystem Sensitivity to Acidic Deposition Acidic deposition derived from sulphur and nitrogen pollution
Acidic deposition derived from sulphur and nitrogen pollution can cause many environmental problems which, until recently, were considered to be confined to Europe and North America. It is now clear that regional air pollution is a serious and growing problem in many parts of the World, particularly in certain developing countries. European and North American countries have now committed themse...
متن کاملEffects of acidic deposition on forest and aquatic ecosystems in New York State.
Acidic deposition is comprised of sulfuric and nitric acids and ammonium derived from atmospheric emissions of sulfur dioxide, nitrogen oxides, and ammonia, respectively. Acidic deposition has altered soil through depletion of labile pools of nutrient cations (i.e. calcium, magnesium), accumulation of sulfur and nitrogen, and the mobilization of elevated concentrations of inorganic monomeric al...
متن کاملA new look at liming as an approach to accelerate recovery from acidic deposition effects.
Acidic deposition caused by fossil fuel combustion has degraded aquatic and terrestrial ecosystems in North America for over four decades. The only management option other than emissions reductions for combating the effects of acidic deposition has been the application of lime to neutralize acidity after it has been deposited on the landscape. For this reason, liming has been a part of acid rai...
متن کاملLuminosity Effects in Projected Fractals
The use of two-dimensional catalogues in unraveling the large-scale distribution of extra-galactic objects can reveal more information than has been supposed if the objects have approximate scaling properties such as observations suggest. After a brief general discussion of this issue, we turn to specific examples of projected fractals for the case where the objects studied have a Schechter lum...
