Atmospheric Nitrogen Pollution in Urban Ecosystems
Nitrogen emissions from electrical power plants, automobile exhaust and fertilizer applications are the major sources of nitrogen deposition in rain and snow onto ecosystems of the northeastern United States. Small amounts of nitrogen deposition can serve as fertilizer and stimulate productivity of plants. However, high rates of atmospheric deposition can lead to a series of negative consequences, including reductions in plant diversity, acidification of soils and waterways, and negative effects on human health. Boston University Associate Professors Pamela Templer and Lucy Hutyra established an atmospheric deposition monitoring site at the Arnold Arboretum earlier this year to measure and monitor rates of atmospheric deposition throughout the year in the City of Boston. This site is now part of the national network of deposition sites, known as the National Atmospheric Deposition Program (NADP), made possible through a grant from the DaRin Butz Foundation. Come find out what their research reveals about nitrogen in the City of Boston. Meet at the top of Weld Hill, behind the Weld Hill Research Building at 3:30pm on Tuesday, July 26.
Parking: Park in the upper spaces at the Weld Hill Building, 1300 Centre Street, Roslindale. Walk up the road behind the building and follow signs to the meeting location on the hill.
Public Transportation: Take the MBTA Orange Line to Forest Hills. Transfer to the #38 bus, and exit at Centre and Buchanan Streets, the stop just after the intersection of Centre Street and the VFW Parkway. OR take the MBTA Green Line to Cleveland Circle, and transfer to the #51 bus. Exit at Centre and Weld Streets, and walk north on Centre Street approximately 800 feet to the Weld Hill Research Building on your right.
