Improving China's acid rain control strategy
October 15, 2009Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely overlooks. The study, which suggests that government officials adapt a more comprehensive pollution control strategy that includes a new emphasis on cutting nitrogen emissions, is scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology, a semi-monthly journal.
Lei Duan and colleagues explain that China is trying to stop soil acidification by reducing sulfur dioxide pollution from electric power plant smokestacks. Those emissions cause acid rain, which in turn has made vast areas of farmland more acid and less productive. China's is striving for a 10 percent reduction in sulfur dioxide emissions by 2010, a policy that seems have had only a limited impact so far, the researchers say. However, China has paid little attention to pollution from nitrogen oxides, which also contribute to acid rain and soil contamination.
The scientists' analysis found that the benefits of sulfur dioxide reductions will almost be offset by increased nitrogen emissions. To control this problem, "China needs a multipollutant control strategy that integrates measures to reduce sulfur, nitrogen, and particulate matter," the article notes.

Acid Rain Current Events and Acid Rain News RSSManaging ecosystems in a changing climate
Global warming may impair the ability of ecosystems to perform vital services-such as providing food, clean water and carbon sequestration-says the nation's largest organization of ecological scientists.
Wilder weather exerts a stronger influence on biodiversity than steadily changing conditions
An increase in the variability of local conditions could do more to harm biodiversity than slower shifts in climate, a new study has found.
Interactions with aerosols boost warming potential of some gases
For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate.
Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began.
Portable and precise gas sensor could monitor pollution and detect disease
In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function.
The Sky Is Not Falling: Pollution in eastern China cuts light, useful rainfall
New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23 percent the number of days of light rain in the eastern half of the country.
Earth's biogeochemical cycles, once in concert, falling out of sync
What do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles that involve all three.
Nitrous gases and zinc in the crosshairs

Ancient volcanic eruptions caused global mass extinction
A previously unknown giant volcanic eruption that led to global mass extinction 260million years ago has been uncovered by scientists at the University of Leeds.

Our Environment - Acid Rain by Peggy J. Parks (Author) In the 1980s scientists made a frightening discovery-forests, lakes, and rivers all over the world were dying at an alarming rate. Then they found the reason: acid rain. For decades, the burning of fossil fuels had built up nitrogen and sulphur oxides in the atmosphere. When these gases joined with water vapor, the result was deadly acid rain. This book explains what acid rain is, what causes it, the damage it has done, and measures being taken to stop it. |
