Rezumat:

Heavy metals toxicity is the result of their interactions with the enzymatic systems from the animal cells or some constituents of cells membranes. The interactions of heavy metals with usual elements from diet (Pb, Cd) have an important role in acute and chronic toxicity. Population can be contaminated with heavy metals by ingestion of contaminated or polluted food or water. The concentration of heavy metals in food products is varied, depending on their origin, storage conditions and progressing technologies.
The study presents the results obtained in 2005 year of some metals (Pb, Cd) in the food (meat, milk, vegetables, juice, diets), in Romania area. Trace elements concentrations were analyzed by atomic absorption spectrophotometer, using a Carl Zeiss Jena, Model AAS-1N, with flame air-acetylene
In all analyzed samples these metals were found. Generally, a wide variation between individual samples was observed.
