Mr. Andrew Downer Foreign Minister Parliament House, Canberra ACT AUSTRALIA Dear Mr. Downer, The alarming persistence of Dieldrin and PCBs in the environment, as demonstrated by the high concentrations of these chemicals found in Port Adelaide dolphins, is a matter of great concern to all Australians. Please sign the Stockholm Convention on POPs and ratify this convention into domestic laws without delay. I wish to add my name to the growing list of Australians concerned about this issue and chemical pollution generally. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
