A Texas petrochemical plant had elevated standardized mortality ratios for neoplasms of the brain. A case-control study examined possible associations between glio mas of the brain and job title, departmental employment history, chemical exposure his tory, geographic location within plant, dates of employment and residence. The greatest apparent risks were associated with exposure to carbon dioxide, diethyl sulfate, diethylene glycol, ethanol, ethylene, isopropanol, mclhanociraethxlene alycoi. and vinyl acetate; f with first employment in Ute T9<0s or early 1950s, and with residence in La Marque, Tex. No significant differences between cases and controls were apparent in duration ofexpo sure to any of these chemicals. Intiml'ictioa In February 1979, the National Institute for Occupational Safety and Health (NIOSH) and OSHA, with the aid of the company management, t began an investigation of a cluster of primary brain tumors at a chemicals and plastics plant in Texas City, Tex. Alexander et al. [1] have described the characteristics of the brain tumor cases and the methods for case identifi cation. Two retrospective cohort mortality studies ofall male hourly work ers employed at this plant from 1941 through 1977 have been reported [2, em3S.KiumrAG.foNi aZSI-MSO'lMXOMMTfSt.TS/O : :r v ` UCC 099761
