Thyroxine and Free Thyroxine Levels in Workers Occupationally Exposed to Inorganic Lead
BACKGROUND The effects of lead exposure on thyroid function are unclear. METHODS Serum thyroxine (T4) was evaluated among 137 lead-exposed workers and 83 non-exposed workers. Free thyroxine (FT4) was evaluated among a subset of these workers. Exposure metrics included blood lead level (BLL), which reflects recent exposure, zinc protoporphyrin (ZPP), a marker of intermediate-duration lead expo...

Brien, T. G., Fay, J. A., and Griffin, E. A. (1974). Archives of Disease in Childhood, 49, 225. Thyroid status in the newborn infant: effective thyroxine ratio and free thyroxine index. The effective thyroxine ratio (ETR) was determined in 28 term and 17 premature infants at birth and in 17 infants aged 0 to 6 weeks. The mean values found were significantly higher than those in 20 adult euthyro...
متن کاملNeurobehavioural testing in workers occupationally exposed to lead.
Although the toxic effects of lead on the central nervous system have been well described, the blood concentration at which lead begins to exert adverse effects remains the focus of debate. A meta-analysis of occupational studies was conducted evaluating the association between neurobehavioural testing results and moderate blood lead concentrations.
متن کاملBlood Lead Levels and Cause-Specific Mortality of Inorganic Lead-Exposed Workers in South Korea
The objective of this study was to identify the association of blood lead level (BLL) with mortality in inorganic lead-exposed workers of South Korea. A cohort was compiled comprising 81,067 inorganic lead exposed workers working between January 1, 2000, and December 31, 2004. This cohort was merged with the Korean National Statistical Office to follow-up for mortality between 2000 and 2008. Af...
متن کاملAdverse effects in workers exposed to inorganic lead.
This paper describes a retrospective cohort study comparing 60 workers occupationally exposed to inorganic lead and 60 matched controls. All subjects were assessed using data obtained from a specially designed Questionnaire for lead exposure and toxic effects assessment, physical examination, spirometry, ECG, and laboratory tests including blood lead level (BLL) and biomarkers of lead toxic eff...
