Metal levels in organically and conventionally produced animal and vegetable products in Turkey.

Lead, cadmium, copper, zinc and iron levels were determined in organically and conventionally produced wheat, green lentils, flower honey and eggs that are supplied on different markets in Ankara, Turkey. Their toxicological and nutritional values were compared with national and international limits and literature data. The levels of cadmium and lead in conventionally and organically produced wheat, green lentils, honey and egg were below the limit of detection (LOD), whereas the level of copper was only below LOD in honey and eggs. The levels of Zn and Cu were found to be higher in conventionally produced wheat samples than organically produced ones; whereas the level of Fe in organic products was found to be higher than the conventional products.
