In April, 1985, scientists from China and Canada made a marine enclosed ecosystem experiment cooperatively in Xiamen. The experiment was carried out in the plastic bags in a shorebased tank. To the bags, heavy metals (Cu, Hg, Zn, Pb and Cd) were added quantitatively and their effects on the primary productivity were studied. The results show that the effects of low level metal mixture (Cu 3.5-10.0, Hg 0.2-1.0, Pb 0.3-1.5, Zn 3.5-17.5, In April, 1985, scientists from China and Canada made a marine enclosed ecosystem experiment cooperatively in Xiamen.
