Studies formaldehyde and other aldehydes as a function of building air exchange rates in public buildings and energy efficient research houses. Uses sequential gas bubbling systems in conjunction with a pneumatic flow control system for field sampling. Finds that concentrations of formaldehyde and aldehydes in public buildings are about the same in indoor and outdoor air because of the high ventilation rates in these buildings. However, indoor air in general has higher formaldehyde and total aliphatic aldehyde levels than outdoor air. Residential buildings and office trailers in particular have concentrations that can exceed the European indoor formaldehyde standard of 120 microgms/m3.
