An Air Quality Learning and Demonstration Center has been developed within the Arboretum at Penn State Univ.. The Center provides opportunities where students (of all ages) and teachers (grade-school through to classes within the Univ.) can learn about air quality as one of our most important natural resources. A seasonally interactive display of air quality monitoring instrumentation, self guided walkways through gardens of air pollution sensitive plant species, innovative techniques for demonstrating the effects of air pollutants on plants, displays of recent research findings, industry supported displays of pollution abatement technologies, and a teaching pavilion are within the Center. A Pennsylvania Dept. of Environmental Protection air quality monitoring station with ozone, sulfur dioxide, nitrogen oxides, carbon dioxide, PM < 2.5 u mass and speciation samplers, and a complete meteorological station provide data on the immediate environmental parameters. These data are relayed to an LCD crystal display board that has been mounted on the outside of the monitoring building; visitors are able to see the various measures of the air quality on a real time basis. Pannier type fiberglass display panels provide understandings of the various facets of air pollution formation and transport phenomena, air quality monitoring methods, the functions of open-top chambers, foliar symptoms expressed by pollution sensitive plants within the bioindicator gardens, and the impacts of pollution on agricultural and forested ecosystems. Handicapped accessible walkways lead visitors throughout the Center to the Teaching Pavilion that easily accommodates 80 persons. The pavilion is equipped with drop down curtains, electric power, and internet connections.

Penn State's Air Quality Learning and Demonstration Center was completed and open to the public in 2003. The facility houses the State College air monitors for the Department of Environmental Protection and contains self-guided walkways through gardens of air pollution sensitive plants, innovative techniques for demonstrating the effects of air pollutants on plants, displays of recent research findings, industry-supported displays of pollution abatement technologies, and a teaching pavilion. One of our outreach projects, funded by the US EPA and the PA Department of Environmental Protections, is to provide enhanced teacher training on air pollution impacts on the regional and specific vegetation through an in-service training for local science school teachers utilizing on-site and archived data on weather conditions and plant injury symptom development. The picture archive began to be developed during Summer 2005 using video cameras that are permanently mounted for the growing season inside the open-top chambers and focused on a plant (and a specific leaf or set of leaves). Once the teachers are trained to utilize these data sets appropriately, they will be able to access the data during the school year through the Learning Center website and conduct the same analysis with their students in their classroom during the school year. This use of archival information is important because the school year does not coincide with optimum times for observing air pollution symptoms on vigorously growing field-grown plants in Pennsylvania (which is best during the summer).

The use of ornamental plants in interiorscapes is increasingly being studied for their ability to remove volatile organic compounds, thereby improving the air quality of indoor environments ( Kim et al., 2008 ; Yoo et al., 2006 ). Deterioration of

Many undergraduates major in horticulture because they love working with plants. When they hear research that documents how people respond-to plants, some students -begin to understand why they have responded positively to plants, and they want to learn more about the topic. This paper 1) discusses the potential to use students' excitement about human issues in horticulture to teach principles that educators consider important components of a baccalaureate degree, and 2) presents the case of one student to demonstrate how it can be done.

Air quality monitoring is carried out in Canada and the United States by air pollution control agencies in order to:

  1. provide information on the quality of the ambient air and determine long-term trends;

  2. identify pollutants and their sources, and determine the effects of emission controls on air quality levels;

  3. control episodes brought on by unique weather conditions by obtaining data on a real time basis and ordering emergency shutdowns of sources of pollution. Air pollution episodes during which hazardous air quality levels are reached may thus be prevented;

  4. determine background levels to assist in determining the transport diffusion and fate of the pollutants emitted, and the chemical reactions which take place in the atmosphere;

  5. research the effects of pollutants on health, property, and vegetation to enable the agencies to set meaningful air quality criteria and standards.
