Abstract

Cadmium and lead are the elements which are characterized by high toxicity. These elements do not bring any benefit to the organism and their presence is harmful in almost any dose. These elements can accumulate in body tissues for years and it takes a lot of time until the body can expel them. They can lead to the malfunction of internal organs, cellular metabolism or DNA damage. The main sources of cadmium emissions are industry, batteries, fertilizers, and municipal waste. The biggest source of lead emissions into the environment in the twentieth century were fuels. Areas that belong to the most polluted are those where the lead is still used as an additive for fuels. The research material was human teeth, which were collected from residents of the Kazimierza County. 170 teeth of all types have been examined - 67 belonged to men, and 103 to women. The entire study material has been divided into eight age groups. The teeth were subjected to washing, drying, weighing and mineralization. The heavy metal content was measured by an atomic absorption spectrophotometer (FAAS). Statistical analysis was performed in the program StatSoft Statistica 8.0. The results confirmed the presence of heavy metals in the teeth. The highest concentrations of cadmium and lead have been found in the oldest age group.
