The association of chromium in household dust with urinary chromium in residences adjacent to chromate production waste sites.

Several previous studies of exposure to chromium waste in New Jersey have shown that Cr levels are elevated in household dust in homes adjacent to waste sites and that Cr levels in the urine of residents near sites are also elevated compared to control populations. It has not been possible until now, however, to examine these external and internal measures of exposure together in a large population to determine whether the external exposure is predictive of the internal exposure. We investigated the relationship between various adjusted and unadjusted measures of spot urine Cr concentration and household dust Cr from residents and residences adjacent to known Cr waste sites. Statistically significant bivariate relationships were found between log-transformed urine Cr concentration and Cr dust concentration (micrograms of Cr per gram of dust) but not Cr dust loading (nanogram Cr per square centimeter). Log-transformed urine concentration was used as the dependent variable in multiple regression analysis of the total population (n = 329), the population [less than/equal to] 10 years old (n = 67), and the population >10 years old (n = 262), with Cr dust concentration as a mandatory independent variable. Other potential direct influences on urine Cr were investigated as potential confounders of this relationship. In the final models for the entire population and those [less than/equal to] 10 years old, but not for those >10 years old, Cr dust concentration remained significant. This suggests that exposure of young children to Cr in household dust accounts for much of the relationship in the entire population.

Public drinking water contamination and birth outcomes.

The effects of public drinking water contamination on birth outcomes were evaluated in an area of northern New Jersey. After excluding plural births and chromosomal defects, 80,938 live births and 594 fetal deaths that occurred during the period 1985-1988 were studied. Information on birth outcome status and maternal risk factors was obtained from vital records and the New Jersey Birth Defects Registry. Monthly exposures during pregnancy were estimated for all births using tap water sample data. Odds ratios of > or = 1.50 were found for the following: total trihalomethanes with small for gestational age, central nervous system defects, oral cleft defects, and major cardiac defects; carbon tetrachloride with term low birth weight, small for gestational age, very low birth weight, total surveillance birth defects, central nervous system defects, neural tube defects, and oral cleft defects; trichloroethylene with central nervous system defects, neural tube defects, and oral cleft defects; tetrachloroethylene with oral cleft defects; total dichloroethylenes with central nervous system defects and oral cleft defects; benzene with neural tube defects and major cardiac defects; and 1,2-dichloroethane with major cardiac defects. Total trihalomethane levels > 100 ppb reduced birth weight among term births by 70.4 g. By itself, this study cannot resolve whether the drinking water contaminants caused the adverse birth outcomes; therefore, these findings should be followed up utilizing available drinking water contamination databases.
