Staten Island/New Jersey Urban Air Toxics Assessment Project
|The project was a program of ambient air monitoring and meteorological data collection from October 1987 through September 1989, and indoor air sampling from July 1990 through mid-March 1991. An emission inventory was conducted to assist source identification and support risk management where the risk assessment indicated such a need.|
This study examined the levels of toxic air pollutants in the Staten Island/New Jersey area and was designed to assess the health risks (cancer and noncancer) to the residents of Staten Island due to the emission of these toxic air pollutants. Estimation of risk of cancer and noncancer effects from lifetime inhalation exposure to air toxics released from point, area, and mobile sources. A limited study of indoor air and an odor monitoring study was also carried out.
Completed reports available from National Technical Information Service (NTIS), telephone number (703) 878-4650.
Assessment and Analysis Methods
2. What assessment features does the project use?
|1. Did this project include a health effects evaluation or exposure assessment?|
|3. If an inventory is used in the project, how will it be developed? |
|An emission inventory was developed categorizing sources as point sources, area sources, or mobile sources. Point sources were any facility located in the study area and appearing in the 1988 Toxic Release Inventory (TRI); the New Jersey Department of Environmental Protection Air Pollution Enforcement Data System (APEDS); the New York State Department of Environmental Conservation Source Management System (SMS); the New York City Department of Environmental Protection, Bureau of Air Resources Air Management Information System (BARAMIS); and the EPA Region II/Air Programs Branch POTW Emission Inventory; and the following area sources included as point sources because of the magnitudes of their emissions: landfills, hazardous waste treatment storage, and disposal facilities, publicly-owned treatment works, hospital sterilizers, and industrial dry cleaners. Area sources and mobile sources were included as well. See the summary report for further detail.|
|4. What sources of emissions are addressed? |
|Stationary Major Sources, Mobile Sources, Stationary Area Source|
|5. If monitoring is conducted, how are the data used in the studies? |
|Ambient air samplers were set up based on consideration of residential neighborhood complaints, availability, accessibility, security, absence of known sources nearby, geographic distribution, proximity to breathing zone, and consistency with the U.S. EPA air monitor siting requirements. Ambient air samples were collected on every sixth day from October 1987 through September 1989 at 13 sites for VOC sites, at 5 sites for metals and benzo[alpha]pyrene, and 5 sites for formaldehyde. In the indoor study, 12 volatile organic chemicals (VOCs) were measured in 2 homes in New Jersey and 2 homes in Staten Island, with simultaneous measurements at one outdoor site near each set of homes. Samples were taken every 12th day using canisters.|
|6. What pollutants are monitored? |
|112-Trichloroethane, Barium compounds, Beryllium compounds, Bromoform, Cadmium compounds, Carbon tetrachloride, Chlorobenzene, Chloroform, Chromium compounds, Cobalt compounds, Copper compounds, Ethylbenzene, Hexane, Iron compounds, Lead compounds, m-Dichlorobenzene, Manganese compounds, Mercury compounds, Molybdenum compounds, Nickel compounds, o-Dichlorobenzene, p-Dichlorobenzene, Selenium compounds, Styrene, Toluene, Trichloroethylene, Vanadium Compounds, Zinc compounds|
|7. If modeling is conducted, what types of models are used? |
|A pollutant rose model and a surface trajectory model. |
A pollutant rose model was used in assessing long-term air toxics transport patterns and a surface trajectory model was used to evaluate short-term or episodic periods.
