The level of organic contaminants in the carcass of a Chinese white dolphin found off Tuen Mun's Butterfly Beach on February 19 was normal and not the cause of its death, Secretary for Environment, Transport and Works Sarah Liao Sau-tung said yesterday. In a reply to lawmaker Choy So-yuk, Dr Liao said analysis by the Agriculture, Fisheries and Conservation Department showed heavy metal contaminants found in liver tissue samples of 25 other white dolphin carcasses were within normal range. Five stranded dolphins were found in the territory last year, 13 for 2005 and 10 for 2004.
