Abstract
Occupational hazards resulting from workplace exposure to phthalate esters, and NIOSH concerns related to them were briefly reviewed. Workplace exposures to phthalate-esters can occur as a result of contact with di(2-ethylhexyl)phthalate (117817) (DEHP) during respirator quantitative fit testing, handling of plasticizers, and during air filtration system leakage testing. During respirator quantitative fit testing, a polydisperse DEHP aerosol is used as a test atmosphere to measure respirator faceseal leakage. NIOSH has suggested the use of alternative aerosols in such testing. Refined corn oil was considered by NIOSH to be the aerosolized agent of choice for such respirator faceseal leakage tests. Exposures of workers to DEHP containing plasticizers in the plastics industry is also under evaluation by NIOSH. Problems have been encountered in the biohazard testing of thermally generated DEHP aerosols during leak detection in air filtration systems due to the difficulty in interpreting exposures to breakdown products of DEHP occurring at elevated temperatures. For this reason, NIOSH has suggested a filter test utilizing DEHP nebulized at room temperature in place of a thermally generated aerosol.
