title: An epidemiologic investigation of birth outcomes in relation to dibromochloropropane contamination in drinking water in Fresno County, California, USA.
abstract: This report describes an epidemiologic investigation of the relationship between dibromochloropropane (DBCP), contamination in drinking water and birth outcomes between 1978 and 1982 in Fresno County, California, USA. Census tracts in the county were categorized according to DBCP level in drinking water. A direct comparison between exposure categories was done by the use of the Mantel-Haenszel chi-square procedure to compute relative ratios or risks for low birth weight and birth defect, adjusting for age, race, percent Hispanic, and parity. No correlation between these birth outcomes and DBCP contamination was found. In addition, we did not find any difference in sex ratio in relation to DBCP contamination.
