The effect of environmental factors on concentration of trace elements in hip joint bones of patients after hip replacement surgery.

The aim of this study was to assess the impact of environmental factors: cigarette smoking, dental amalgam fillings, eating habits and osteoporosis, on the concentrations of copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd) and mercury (Hg) in the bone of hip joint in patients in the Orthopedics Clinic in Szczecin, Poland. Amalgam dental fillings had an effect on the Cu concentration in the cartilage with the adjacent compact bone, and on Hg concentration in the spongy bone. The highest concentrations of Cu and Hg were found in people with multiple amalgam fillings. Smoking appeared to influence Pb concentration in the cartilage with the adjacent compact bone, and Cd concentration in the spongy bone. Increased Pb was detected in smokers, and increased Cd in non-smokers. Diets rich in fish and seafood correlated with Cd concentration in the cartilage with adjacent compact bone. The greatest concentration was in people who ate fish or seafood at least once a month.
