## Abstract The content of selenium and mercury in urine was measured in 28 male workers exposed to Hgยฐ and in 21 unexposed male controls. The first group excreted significantly more selenium into urine as compared with the control group. No significant correlation between mercury and selenium excr

โฆ Synopsis
The concentrations of fluorine (F), sodium (Na), magnesium (Mg), aluminum (Al), potassium (K), phosphorus (P), calcium (Ca), iron (Fe), nickel (Ni), zinc (Zn) and iodine (I) in the hair of 142 hydrofluoric acid (HF) exposed workers and 273 control subjects were analyzed by wavelength dispersive Xray fluorescence spectrometry Postshift urine and serum specimens were also collected for the determination of fluoride To determine whether external contamination influences hair analysis, the control hair samples were kept in the work environment for one week With the exception of lower K and Fe values, the levels of F and other elements in the hair of HF workers were higher than in the control subjects. The concentrations of F in hair and in postshift urine were in good correlation (r = 0 65) In the hair of HF workers F and Ca, F and Mg, F and P, F and Al were well correlated with each other (r > 0 6) F concentration in the hair increased after the sample was retained, however, it decreased to the reference value after washing The levels of Ca, Mg and other elements did not change during the experiment.

Background To further assess the utility of targeted blood lead screening for children from households with members having occupational lead exposures, we conducted a meta-analysis of all available reports of take-home lead exposures. Our objective was to estimate the blood lead levels among U.S. ch
