The environment is constantly being polluted by the accumulation of heavy metal contaminants.
This is a matter of serious concern as it adversely affects the health of humans. This research has done
in order to investigate the interaction effects of different concentration of zinc and copper on
antioxidative enzyme activities in leaf of summer squash. The Copper concentration is (0.05, 0.1, 0.2)
mg/l and the Zinc concentration (0.22, 5, 10) mg/l. The high amount of Copper in summer squash
(Cucurbita pepo) rises CAT enzyme activity in leafs of this plant. While, using the Zinc treatment in
high concentration decreas total solution protein content. The CAT enzyme activity in (Zn3+ Cu2)
treatment in comprises with control treatment is increased and amount of total solution protein in (Zn2-
+ Cu2) treatment is decreased.
