“…Reports on contamination of indoor air by PCP vapor emitted from PCP-treated indoor wooden structures have appeared in the literature (Gebefugi et al, 1979;Whitney and Gearhart, 1979;Saur et al, 1982). The rate of vaporization of PCP is increased with rise in temperature (Ingram et al, 1986). Most of the people spend a major portion of the day indoors.…”

Indoor Air Contamination With Polychlorinated Dibenzo-p-Dioxins and Dibenzofurans

Pentachlorophenol (PCP), used extensively for wood preservative purposes, contains trace amounts of polychlorinated dibenzodioxins (PCDDs) and-dibenzofurans (PCDFs) as contaminants. Residues of these compounds are present on the surface and sub-surface of the treated wood. These contaminants have the potential to wear (or migrate) away or volatilize from the wood surface and become entrained in ambient air or dust particles, and thus becoming available for human contact. During the early sixties several day nursery facilities were built with PCP-treated wood in the northern part of West Germany. In this paper we describe the indoor air monitoring data in these kindergarten buildings and the associated possible long-term health risk. The indoor ambient air was found to be contaminated with highly toxic PCDDs/PCDFs at pg/m3 levels. HxCDDs, HpCFs and OCDDs/OCDFs congeners were the major contaminants.

“…The latent heat of vaporization of the PCP solvent (∆Hvap) was estimated from these results using the Clausius-Clapeyron relationship between pressure (P) and temperature (T) for a vapor treated as an ideal gas: d(lnP)/d(1/T) ) -∆Hvap/R. An average value of 99.9 kJ/mol is obtained compared to a value of 98.2 kJ/ mol for PCP introduced into the wood cells by a liquefied petroleum gas (19). Field Ambient Air Sample Assessment.…”

The nature of the volatile organic compounds that could be at the origin of the characteristic odor of treated wood utility poles was investigated by the study of compositional changes in the chromatographic profiles of fresh-pentachlorophenol (PCP) solvent samples and weathered samples collected from an in-service red pine pole. Over 99 peaks were identified in the chromatogram of the fresh solvent from which a large portion of the C3-, C4-, C5-, C6-alkylbenzene isomers and early eluting n-alkanes was missing from the analysis of weathered samples. Three domains in the chromatographic profile (volatile, semivolatile, and nonvolatile components) were confirmed by assessing the headspace of fresh-PCP solvent samples using direct syringe sampling and solid-phase microextraction. A first level of field validation was achieved using an emission cell for measuring substances emanating from sapwood specimens at different temperatures. The average latent heat of vaporization (deltaHvap) of the PCP-solvent components was estimated at 99.9 kJ/mol from these results. Finally, the analysis of airborne substances at a treating plant and a utility pole storage site confirmed that the C4-, C5-, and C6-alkylbenzene isomers could contribute to the characteristic odor perceived by humans.
