We investigated whether a possible exposure-response pattern existed between the reported airborne formaldehyde concentrations and the reported hematology responses in the studies that we reviewed.
"The detection levels on the instrumentation used by the EPA were not accurate enough to report airborne chemicals at lower levels," explains Subra.
