Copper content of South African fruits and vegetables

Residue levels of copper were determined in raw samples of fresh commercial fruit and vegetables in South Africa. The study also assessed how these levels compared with the legal maximum permissible residue limit of 20 mg/kg established for these products. Cuu was found at detectable levels in all 6...

Description
Summary:Residue levels of copper were determined in raw samples of fresh commercial fruit and vegetables in South Africa. The study also assessed how these levels compared with the legal maximum permissible residue limit of 20 mg/kg established for these products. Cuu was found at detectable levels in all 645 market samples analyzed. None had residue concentrations exceeding or even nearly approaching the maximum limit. The majority of samples had less than 1 mg/kg Cu, while only 1.4% contained Cu in excess of 3 mg/kg, with none higher than 6 mg/kg.
