Organophosphate triesters in indoor environments.

In this study the occurrence of ten organophosphate triesters in indoor air at 29 different locations was investigated. They were detected at all locations and a total of ten compounds were identified. The predominant compounds were the chlorinated compounds tris(chloroisopropyl) phosphate and tris(2-chloroethyl) phosphate with a concentration around 2 microg m(-3) in some indoor environments. A rough estimation gives at hand a daily inhalation of around 10 microg for each of these two compounds.
