Technical assistance report no. TA-78-46, Potomac Village Shopping Center, Potomac, Maryland.

An environmental sampling survey was performed at the Potomac Village Shopping Center (SIC-6512) in Potomac, Maryland on July 5 to 7, 1978. The tenants of the center requested the evaluation to determine exposure levels to airborne concentrations of formaldehyde (50000), which were thought to account for reports of eye, nose, and throat irritations. Air samples were taken from two of the seven shops in the center and analyzed for formaldehyde content. Time weighted average concentrations at one shop ranged from 0.8 to 1.6 parts per million parts of air (ppm), and at the other shop from 0.8 to 1.2ppm. Both of these levels are below the OSHA standard of 3ppm. Analysis of bulk insulation foam samples revealed high levels of latent formaldehyde. It is concluded that the measured concentrations of formaldehyde do not pose a hazard to the tenants. Modification of the present ventilation system and further latent formaldehyde analysis of the foam insulation are recommended.
