Queens County Community Air Screen Results - United Community Civic Association
Air samples were collected at two locations in Astoria and Jackson Heights neighborhoods in the borough of Queens. The samples were collected for 1-hour with a 6-liter sampling canister and analyzed using a laboratory method which evaluates the presence of 43 toxic air pollutants.
Twenty-five toxic air pollutants were detected and all were well below the short-term health-based air concentration values. Therefore, the results would not be considered a potential public health threat or an immediate public health concern. The results also are below or within an order of magnitude of the long-term health-based air concentration values and similar to concentrations found in the DEC's ambient air monitoring network. Based on these comparisons, DEC staff concluded that follow-up sampling will not be considered at this time.
Sample collection sites were along or near heavily-traveled roadways. Both samples were collected during the evening commute. The results for air toxics commonly associated with localized vehicular sources (e.g., trimethylbenzenes, 1,3-butadiene, benzene, ethylbenzene, xylenes and toluene) are more pronounced in the sample collected at 31st Street and Hoyt Avenue as compared to 82nd Street and Grand Central Parkway. In comparison to other urban areas in the State, the results reflect similar concentrations.
In conclusion, this short-term screening assessment did not identify concentrations of toxic air pollutants that would be considered a public health concern. Additionally, the results do not indicate the need for follow-up sampling at this time.
