Beryllium concentration in pharyngeal tonsils in children.

Power plant dust is believed to be the main source of the increased presence of the element beryllium in the environment which has been detected in the atmospheric air, surface waters, groundwater, soil, food, and cigarette smoke. In humans, beryllium absorption occurs mainly via the respiratory system. The pharyngeal tonsils are located on the roof of the nasopharynx and are in direct contact with dust particles in inhaled air.

Influence of the type of tree habitat on the character of co-occurrence of Fe, Mn, Zn, Cu, Pb, Ni, Cr and Co in the soil of the Tatra Mountain National Park.

The objective of the research was to determine the effect of habitat type of selected species of trees on the nature of co-occurrence of Fe, Mn, Zn, Cu, Pb, Cd, Ni, Cr and Co. The presence of speciation forms of these metals was investigated, with reference to the species composition of tree stands in selected areas of the Tatra Mountain National Park (Chochołowska Valley, Strążyska Valley, Kościeliska Valley, as well as Mała Łąka Valley).Contents of selected metals in samples were determined by the flame ASA method, with an accuracy of 0.

Lead and calcium content in the human hip joint.

Concentration of lead in bone, unlike in soft tissues, increases during the lifetime and reflects severity of exposure to this element. The main aim of the study was to determine concentrations of lead and calcium and to find possible relationship between calcium and lead in the tissues of the hip joints obtained from inhabitants of the Upper Silesian Industrial Area. We also attempted to identify factors that might affect this relationship.

The occurrence of nickel and other elements in tissues of the hip joint.

Nickel is applied in the production of surgical instruments and compounds of nickel affect the osseous tissue. The objective of this study was to determine the contents of nickel and 11 elements in tissues of a hip joint obtained from inhabitants of the Upper-Silesian Industrial Area. The samples were collected intra-operatively during Total Hip Replacement procedures, in most cases the indication for the surgery was hip osteoarthritis.

[The occurance lead and cadmium in hip joint in aspect of exposure on tobacco smoke].

The objective of this study was qualification of content cadmium and lead in selected elements of the hip joint in aspect of tobacco smoking. The material for the research were 5 elements of hip joint (articular cartilage, trabecular bone and cortical bone femur head, fragment articular capsule and fragment trabecular bone from region intertrochanteric femoral bone), obtained intraoperatively during endoprothesoplastic surgeries. The samples come from habitants of Upper Silesian Region.
