Arsenic content in the femur head of the residents of southern and central Poland.

Arsenic content was assayed in the samples of the femur head of the people living in southern and central Poland (Kraków, n=13; Silesian region, n=13; Lódz, n=12). The average age being 68.7+/-8.7 yr. Arsenic content in the femur head was determined applying the hydride generation atomic absorption spectrometry (HG-AAS) method after microwave mineralization. The average arsenic contents in the femur head of the residents of the Lódz, Kraków, and Silesian regions were 0.41 microg/g, 0.37 microg/g, and 0.18 microg/g, respectively. No correlation has been found between arsenic content in the femur head and the content of other metals. Neither the age nor sex of the people tested affected the arsenic content in the femur head.
