INFORMATION REGARDING CHLOROFORM, 1-BROMO-3-CHLOROPROPANE, AND
GREAT LAKES CHEMICAL CORPORATION

URBAN/SUBURBAN: Source-dominated air samples contained 1-bromo-3-chloropropane at a median concentration of 2 parts/trillion(1). Air samples collected from a geographic area associated with the bromine industry in Arkansas contained 1-bromo-3-chloropropane at unreported concentrations(2). Ambient concentrations of 1-bromo-3-chloropropane in air surrounding the Ethyl Corporation, Magnolia, AK in July 1977 ranged from trace levels to 1,688 ng/cu m(3). Ambient concentrations of 1-bromo-3-chloropropane in air surrounding the Great Lakes Corporation and the Michigan Chemical Corporation in El Dorado, AK in July 1977 ranged from not detected to trace levels and trace to 63 ng/cu m, respectively(3).

Human Toxicity Excerpts :

A historical prospective mortality study was conducted for 3579 white male workers employed between 1935 and 1976 at four Vesicol Chemical Corporation facilities. The members of the study cohort were potentially exposed to brominated compounds including 1,2-dibromo-3-chloropropane (DBCP), tris(2,3-dibromopropyl)phosphate, trimethylene chlorobromide. Some were exposed to DDT, polybrominated biphenyls (PBB) and others to radiation from rare earths process. Overall mortality was lower than expected, particularly in diseases of the circulatory system, nonmalignant respiratory diseases and diseases of the digestive system. No significant overall or cause specific mortality excess was noted among those potentially exposed to either TRIS or DDT. No cancer death was noted among the rare earth employees. Mortality from diabetes mellitus was significantly elevated among the maintenance workers hired in the early 1940's. A significant mortality excess due to diseases of the circulatory system was observed among workers potentially exposed to DBCP and or rare earth process. Mortality from testicular cancer was significantly higher in those exposed to organic bromides. The common potential exposure of the testicular cancer decedents was methyl bromide. A number of other cause specific mortality excesses were also noted.
