This study examines the food-chain transfer of Zn from two plant species, Urtica 31 dioica (stinging nettle) and Acer pseudoplatanus (sycamore maple), into their corresponding 32 aphid species, Microlophium carnosum and Drepanosiphum platanoidis. The plants were 33 grown in a hydroponic system using solutions with increasing concentrations of Zn from 0.017 34 to 42 mg Zn/l, although U. dioica o...
