Summary Report, NIOSH-EPA Interagency Agreement for the Assessment of Human Health Effects from Exposure to Di-2-(Ethylhexyl) Phthalate.
NIOSH 1983 Apr:15 pages
A suitable worker population was sought to conduct a retrospective cohort mortality study for occupational exposure to di-2- (ethylhexyl)phthalate (117817) (DEHP). Companies were contacted regarding annual DEHP consumption or production, types of processes for which DEHP was used, the size of the potentially exposed workforce, and the length of time DEHP had been used. The Society of the Plastics Industry stated that the major use of DEHP was as a plasticizer in polyvinyl-chloride (9002862) (PVC) products. The highest potential source of worker exposures was during the formulating and compounding of the plastic resin. Surveys were then conducted of a plastics manufacturer, a PVC plastic sheet processing facility, and two aerosol filter testing facilities. Field monitoring was conducted of worker exposures to DEHP. The authors conclude that the populations exposed to DEHP were too small and not employed long enough to offer a suitable study cohort. Field monitoring showed worker exposures of less than 0.5 milligrams per cubic meter which was well below the OSHA standard of 5mg/m3. It is recommended that a retrospective mortality study not be pursued at this time.
