Popis: Background. The aim of the study has been to determine mercury content in selected biological samples: pharyngeal tonsils, gallbladder and femoral head tissues. Methods. Hg content in pharyngeal tonsils (n474), deposits of the gallbladder (n180) in femoral head tissues (n319) has been determined by ICP-AES method with the use of the plasma spectrophotometer Optima 5300DV. Biological samples were dissolved by nitric acid (V) in pressure digestion system in a closed system PD 3-6. Results. Co-occurrence of Hg with other elements was assessed based on two way correlation analysis results. The analysis of mercury co-occurrence with other elements in exemplary biological samples was carried out for samples in which Hg content generally ranged: in femur bone tissue from 0,02–0,97 μg/g; in hydroxyapatites of deposits of the gallbladder from 0,02–0,99 μg/g and in pharyngeal tonsils of children from 0,05 to 5,85 μg/g. Because pharyngeal tonsils are located in the main stream of inhaled air where the highest concentration occurred, the highest accumulation of mercury Hg with other trace elements also occurred. The number of significant accumulations is the greatest and the results are very important in the risk evaluation of two way correlation analysis concerning femoral head tissues. In deposits of the gallbladder the changes of mercury content significantly correlated directly proportional (r0,80 p0,005) Ag, Sr, Ba, Se, Cu, Al in women and in men Cu (r0,80 p0,001). Conclusion. Biological availability of some elements such as As, Se, Be, Sb had a big impact on Hg content in single investigated tissues. The choice of a given biological sample, for risk assessment of Hg, ought to take into account pilot studies results on how mercury co-occurs with other metals.
