This study involved the determination of heavy metals of Cd, Cr, Cu, Pb and Zn in cauliflower (Brassica oleracea L. var botrytis L.), carrot root (Daucus carota L.), tomato fruit (Lycopersicum esculentum Mill.), onion bulb (Allium cepa L.) and leafy cabbage (Brassica oleracea L. var capitata L.) and the respective soils from Lushoto District, Tanzania. Samples were collected from eight growing ...

23 The concentrations of 9 elements (Ag, As, Cd, Co, Cr, Cu, Mn, Ni and Zn) were measured 24 in the oyster Isognomon isognomon and the edible clam Gafrarium tumidum from different 25 sites along the SW New Caledonian coast which is subjected to important chemical inputs due 26 to intense land-based mining activities (New Caledonia is the third world producer of nickel). 27 Results indicate that...

This paper studied the association between metals accumulation in selected tissues and the shell and antioxidant defence system in Helix aspersa snails. Accumulation of Zn, Fe, Pb, Cd, and Mg was organ-specific and was the highest in the hepatopancreas. Hepatopancreatic catalase and glutathione peroxidase activities were the highest, whereas the highest glutathione reductase activity was record...
