Mr. Bernard P. Orlan March 4,2002 Air Sampling for Lead Page 2 Stuwesant Hieh School ATC Project No. 15-19125-0246
The established regulatory values for metals are intended for industrial workplace exposures and are not generally applicable to office/school settings. There are no standards for these metals in indoor air in non-industrial situations. The Environmental Protection Agency’s ambient air standard for lead is 1.5 micrograms per cubic meter of air (1.5 ug/m^), this is a three-month average. The sampling method used for these samples was an attempt to duplicate the EPA’s method of sample collection as described on the EPA’s September 11“* website. The lead in air results reported there are from twelve-hour samples.
Tim Amstislavskiy, Environmental Technician from ATC’s New York City office, collected the samples.
Results
The levels of airborne lead did not exceed the limits of detection in any of the samples (<0.2 ug/m^) except for one sample collected in the 9* floor hallway by Classroom 921. Airborne lead in this sample (Sample #09) was found to be 0.4 microgram per cubic meter (ug/m’).
ATC appreciates the opportunity to provide this indoor air quality service to the BOE. Please call me at (212) 353-8280 extension 212 if you have any questions.
Sincerely, ATC Associates, Inc.
James R. Cohn, CIH, CSP Regional Manager Industrial Hygiene Division
