Selenium concentrations in human renal cortex, liver, and hair in northern Poland.

The aim of this study was to (1) determine the selenium concentration in the renal cortex, liver, and hair in 64 residents from northern Poland (Gdańsk region) aged 17-81 yr, who died suddenly, and (2) assess whether a correlation between the selenium concentration in hair and in the renal cortex and liver occurs. Selenium was determined by atomic absorption spectrometry using the hydride generation method. The mean selenium concentration in the renal cortex, liver, and hair in the investigated persons was 0.

Selenium levels in human plasma and hair in northern Poland.

The aim of this study was to (1) estimate the concentration of selenium in the plasma of 146 residents (65 men and 81 women) and in the hair of 34 persons from the Gdańsk region in northern Poland, aged 19-70 and (2) compare the obtained results with data corresponding to healthy populations living in different European countries. Selenium in plasma was determined by atomic absorption spectrometry using the hydride generation method. The mean selenium concentration in plasma of the investigated persons was 73.

Total mercury in human renal cortex, liver, cerebellum and hair.

The aim of this study was: (a) to estimate the concentration of total mercury in the renal cortex, liver, cerebellum and hair of 46 persons who died suddenly in the Gdańsk region, northern Poland, between the ages of 17 and 90; and (b) to assess whether a correlation occurs between mercury content in the investigated biological media. The mean concentrations of mercury in the human hair, renal cortex, liver and cerebellum were: 378 +/- 315.4 ng/g; 68.

Cadmium content in human kidney and hair in the Gdańsk region.

Concentrations of cadmium were determined in the renal cortex and hair of 67 persons who died between 1996 and 1997 in the Gdańsk region of Poland. The mean concentrations in the renal cortex and the hair were: 39.8 +/- 21.

Lead and fluoride content in human bone and hair in the Gdańsk region.

The post-mortem lead and fluoride content in the rib bone and hair of 59 persons from the Gdańsk region was determined. Fluoride was estimated potentiometrically using a fluoride-specific electrode. Lead was determined by atomic absorption spectrometry.
