Maryland Ecosystem Services - Atmospheric Ozone Removal - kg per year

This layer quantifies the yearly removal of atmospheric oxone (O3) by trees. The forests of Maryland play an important role in reducing air pollution in the state. Trees remove pollutants from the air by absorption through leaf stomata and interception by leaves. The forest soil is also a large and important sink for air pollutants. This ecosystem service is especially important due to its effect on human health. The pollutants removed from the air by trees can have many negative effects on human health, causing or exacerbating bronchitis, cardiovascular stress, and asthma. This effect is greater in urban areas, due to a higher concentrations of air pollution in urban areas. This data layer was created as part of the Maryland Department of Natural Resources "Accounting for Maryland's Ecosystem Services" program. This is a MD iMAP hosted service.
