Since then until the present, JK has participated in studies related to the corrosive effects of acid deposition
on the limestone surfaces of Mesoamerican archaeological sites (e.g., Kahl et al.
Liu KH, Fang YT, Yu FM, Li FR, Liu Q, Peng SL (2010) Soil acidification in response to acid deposition
in three subtropical forests of subtropical China.

The eco-cause of the day was acid rain in the Northeast, caused in part by utility emissions of sulfur dioxide and nitrogen oxides, which increased acid deposition
in particle form on the ground and raised the PH of rain and snow when mixed in the atmosphere.
Acid rain (acid deposition
) occurs in highly industrialized regions of the United States and results when sulfur dioxide (S[O.sub.2]) and nitrogen oxide (N[O.sub.x]) gases react in the atmosphere with water and oxygen to form mild solutions of sulfuric and nitric acid.
These volumes, from "Acid Deposition
and Energy Use" to "World History and Energy" can be used as reference material or for just plain interesting reading.
Potential threats include acid deposition
, forest defoliation caused by exotic insects, and fire.
Through various means, acid deposition
can be harmful to human health, ecosystems, and material and cultural resources.
Meanwhile, areas of the state with higher-calcium soils (which can better withstand acid deposition
), "often have high deer populations and excellent regeneration of trees."
Emissions of air pollutants also contribute to a suite of atmospheric issues, including stratospheric ozone depletion, acid deposition
, ground-level ozone, particulate matter, and hazardous airborne pollutants.
CLF Senior Attorney Christopher Kilian says, "Over the last 10 to 15 years, the governors of New York and New England have been firmly in favor of curbing emissions of sulfur dioxide [[SO.sub.2]] and nitrogen oxide [[NO.sub.x]] from coal-fired power plants in the midwest, a major contributor to acid deposition
. [[SO.sub.2]] emissions from some plants have gone down, but now we're seeing that the problems may be far more difficult because of nitrogen pollution from cars, and power plants are still major polluters.
The draft, to be adopted Thursday, says the Acid Deposition
Monitoring Network in East Asia (EANET) aims to create a common understanding on acid rain, provide information on acid rain to national- and regional-level policy-makers, and promote cooperation among countries on the issue.
also arises from nitrogen oxides released from traffic emissions.
The 1990 Amendments require that the maximum release of [SO.sub.2] must be reduced to 10 million tons per year to decrease acid deposition
. By lowering sulfate levels, the Acid Rain Program will reduce the frequency and severity of asthma, bronchitis and other respiratory conditions and will protect crops, wildlife, forests and buildings.
Other possible reasons for the spider's decline include the insecticide lindane, which was sprayed in an attempt to combat the mites, and forest damage resulting from acid deposition
