4 Ecosystems and Air Quality By: EPA Research has linked air pollution to many effects on ecosystems. Studies have shown that air pollutants such as sulfur can lead to excess amounts of acid in lakes and streams and damage trees and forest soils. Nitrogen in the atmosphere has been found to harm fish and other aquatic life when deposited on surface waters. Research has helped to understand ozone pollution's ability to damage tree leaves and negatively affect scenic vistas in protected natural areas. Mercury and other heavy metal compounds that are emitted into the air from combustion of fuel and deposits have been found to accumulate in plants and animals, some of which are consumed by people. Research is conducted to understand the ecological impacts of air pollutants and to support the secondary National Ambient Air Quality Standards (NAAQS), which provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings. Deposition modeling tools are developed, air pollution emissions and precursor pollutants (e.g., ammonia) are measured and pollutant deposition on ecosystems is measured and quantified, among other research activities. Linking Air Quality to Ecosystem Exposure Ecological resources are exposed to atmospheric pollutants through wet and dry deposition processes. A long term goal of multimedia environmental management is to achieve sustainable ecological resources. Progress towards this goal rests on a foundation of science-based methods and data integrated into predictive multimedia, integrated multidisciplinary, multi-stressor open architecture modeling systems. The strategic pathway aims at progressing from addressing one stressor at a time to a comprehensive multimedia-multi stressor assessment capability for current and projected ecosystem health. Over the next several years, EPA's goal for air-ecosystem linkage is the consistent interfacing of weather, climate and air quality models with aquatic and terrestrial ecosystem models to provide the local atmospherebiogeochemical drivers of ecosystem exposure and resultant effects. A goal is also to harmonize the connection of the local ecosystem scale (tens of km 2 ) with the regional airshed scale (thousands to millions of km 2 ). The physically consistent linkage of atmospheric deposition and exposure with aquatic/watershed and terrestrial models is central & has not received adequate attention to date, and needs further development.

5 Ecosystem exposure as the intersection of the atmosphere & biosphere Trees and Air Pollution EPA modelers show how controlling man-made sources of air pollution may also reduce air pollution formed from compounds released from vegetation. EPA researchers have discovered that controlling man-made sources of air pollution will have the added benefit of reducing air pollution formed from compounds released from trees and plants. Trees and plants release more than just oxygen into the atmosphere as a result of photosynthesis. They release a variety of gases that contribute to air pollution. In fact, the planet s vegetation accounts for about two-thirds of the pollutants known as volatile organic compounds (VOCs) emitted globally. In the study, published in the May issue of Environmental Science & Technology, EPA researchers quantified for the first time how emissions from vehicles, industry and power plants interact with natural emissions from vegetation to change the composition and make-up of chemicals in the air for the worse. The implications of the study are considerable. If we can control the man-made sources of emissions, we can indirectly affect the formation of these naturally derived atmospheric pollutant particles, says Dan Costa, National Program Director for Clean Air Research at EPA. Using computerized air quality modeling, investigators conducted simulations of natural and human-related pollution in the United States. When scientists took man-made pollutants out of the simulation, there was a 50 percent drop in pollutants from trees and plants in the Eastern United States. These pollutants, known as secondary organic aerosols (SOAs), are produced by sunlight when VOCs from trees, plants, cars or industrial emissions interact with other airborne chemicals. SOAs are important for the formation of two regulated air pollutants, particulate matter and nitrogen oxide, a greenhouse gas.

6 This study suggests that roughly half of the 'natural' SOA in the eastern U.S. forms only when there is enough man-made pollution around to form it, says EPA scientist and lead author Annmarie Carlton. This model can guide us in developing strategies that can control our atmospheric chemistry, says Costa. Over the last 40 years, similar EPA research efforts to develop a better understanding of clean air science have led directly to policies widely credited with better air quality, which in turn reduces hospitalizations, worsening levels of asthma, cardiac events and even deaths. The research can also guide EPA to develop more refined and focused regulations and strategies for decreasing pollution effectively and efficiently. This is just a first step in gaining an understanding of the complexity of the atmosphere such that we might intervene, says Costa. The research may also have implications for future air pollution management strategies as well. Scientists predict climate change will stimulate the growth of trees and plants and extend growing seasons, resulting in even more emissions from natural sources. By controlling man-made emissions, the impact of emissions from trees and plants may be reduced. Huta Hegerfeld Environmental Works Ltd is proud to say, that it has the capabilities and the experts to conduct the analyses and air dispersion modeling for the various pollutants to predict the significant impact levels which helps in assessing the balance of ecosystem.
