Suffolk County Community Air Screen Results - Kings Park Community
Five air samples were collected in the Kings Park community. Three samples were collected in September 2012 for 1-hour and two samples were collected in June 2013 over a 24-hour period. All 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-seven toxic air pollutants were detected in at least one sample and all were well below the short-term health-based air concentration values. Therefore, the results would not be considered a potential health threat or an immediate public health concern. Based on comparisons among the 1-hour sample results and with the results from DEC's ambient air toxics monitoring network, staff concluded that follow-up sampling should be conducted. The follow-up sampling was collected over a 24-hour period. The 24-hour samples were collected to determine if the results from the 1-hour samples were representative of daily ambient concentrations in the area. The decision to conduct follow-up sampling and the results are discussed in more detail in the complete report (PDF) (1.17 MB).
The follow-up sampling with 24-hour canisters yielded results that were below or within an order of magnitude of the long-term health-based air concentration values. Additionally, the concentrations found were similar to concentrations found in the DEC's ambient air toxics monitoring network.
In conclusion, this limited short-term screening assessment did not identify concentrations of toxic air pollutants that would be considered a public health concern. Although one of the 1-hour benzene readings was higher than the other results, it was consistent with monitored concentrations across the State and was not documented by the 24 hour sampling.
