Distribution of trace elements in the Houston environment: relationship to mortality from arteriosclerotic heart disease.
The relationship of trace elements to arteriosclerotic heart disease (AHD) was assessed. Samples of water supplies in the Houston area were analyzed periodically for cadmium, lithium, iron and zinc. Mortality data for each of the sampling areas, delineated according to boundary of water service, were used to compute average annual age-adjusted death rates for white males aged 35 to 64 during the years 1969 to 1971. Linear regression analyses were performed on the chemical constituents for the age-adjusted death rates due to AHD. Positive correlation coefficients for lithium and zinc were found to be statistically significant at the 0.05 probability level.
