[The effect of combined exposure to chemical and physical factors on the nervous system during aluminum production: a preliminary finding].

Background: The authors present the results of medical examinations of workers employed in an aluminum electrolysis plant with occupational exposure to aluminum dust, polycyclic aromatic hydrocarbons, and magnetic field.

Methods And Materials: The study covered a selected group of 39 male workers (mean age, 44,9; SD = 7.5 years; range 29-55 years) involved in the aluminum production.

Renal and neurologic effects of cadmium, lead, mercury, and arsenic in children: evidence of early effects and multiple interactions at environmental exposure levels.

Lead, cadmium, mercury, and arsenic are common environmental pollutants in industrialized countries, but their combined impact on children's health is little known. We studied their effects on two main targets, the renal and dopaminergic systems, in > 800 children during a cross-sectional European survey. Control and exposed children were recruited from those living around historical nonferrous smelters in France, the Czech Republic, and Poland.

[Asessment of occupational exposure to lead in Poland].

The aim of the study was to assess the current occupational exposure to lead in Poland and to evaluate the competence of laboratories responsible for biological monitoring and analysis of health risks in workers exposed to lead. According to the current data, 26,500 workers are employed in 517 factories, including 1895 persons working under condition of exposure exceeding the Polish MAC level of 0.050 mg/m3.

[Neurologic and neurophysiologic examinations of workers occupationally exposed to aluminium].

Background: Studies conducted to assess aluminum (Al)-induced toxicity to humans and environment. It has been implicated that Al is involved in the etiology of Alzheimer's disease and other neurodegenerative disorders, though this is controversial. The aim of the present study was to assess Al effects on the nervous system functions in workers chronically exposed to this metal.

Effects of occupational exposure to aluminum on nervous system: clinical and electroencephalographic findings.

Objectives: The aim of the present study was to assess the effects of aluminum (Al) on the nervous system functions in workers chronically exposed to Al.

Materials And Methods: The study covered a selected group of 67 male workers (mean age, 38.7 SD 10.

Integrated indexes of occupational exposure as predictors of kidney dysfunction.

The aim of the study was to evaluate the dose-effect and dose-response relationships between the integrated indexes Cd-A x t (mg/m3 x years of exposure) and Cd-B x t (microg/l x years of exposure), and the increase in retinol binding protein excretion in urine (RBP-U) and beta2-microglobulin concentration in serum (beta2M-S). The study was carried out in the nickel-cadmium battery factory in 1998-1999. Exposure to cadmium was formerly very high.
