THE problem of indiscriminate dumping of clinical waste is continuing despite a pledge by the Government to seek ways of overcoming it. In the latest development, 24 ampoules of antibiotics were found washed up on beaches in Sai Kung along with two other larger medical bottles. A subsequent search found more in the same area, on Pak Sha Chau and Kiu Tsui beaches. The find counters the argument that the waste is discarded by drug addicts, which was claimed in September when 50 syringes, some smeared with blood, were found at Rocky Bay in Shek O. It is thought that the waste comes from a private doctor's practice because the department of health buys medicine in bulk and does not use containers as small as those found. The discovery was made by South China Morning Post business editor Ray Heath, who was on a family outing. ''We were walking along the beach north of the pier near Fuk Man Road. There are rock pools there and a little stretch of sand which children play on or fish from,'' Mr Heath said. ''We saw these ampoules washed up. There were 10 of them. There were also some medical bandages that looked unused. My wife is a nurse and she recognised the ampoules as the sort used by doctors. They inject distilled water into them, shake them up and then they're ready for injecting into a patient. '' It would have been no trouble at all for a child to have picked them up and found out the hard way what was in there. ''I was disgusted. It's supposed to be one of the nicer parts of the New Territories out there but it's clearly not safe.'' Beach rubbish collectors said ampoules were frequently found. A collector at Kiu Tsui Beach said she often picked them up. Another said he would seek guidelines on how to manage the waste safely. The two beaches are popular with swimmers. During weekends, hundreds flock there. Gary Tse and his girlfriend, who canoe off Pak Sha Chau, expressed disgust. ''They pose a danger to the swimmers here, especially the children,'' Mr Tse said. ''I think the Government should look into the matter and work out legislation to regulate the disposal of the waste.'' Sai Kung District Board members Wong Shui-sang and Wan Yuet-kau were surprised to learn of the medical waste. Mr Wan, also a Regional Councillor, was concerned that infectious diseases could be transmitted by the waste. ''We are also worried about the dangers to garbage collectors who are exposed to this waste frequently,'' Mr Wan said. He called on the Medical Association to strictly control the disposal of medical waste. ''The Government should investigate the issue and legislate against dumping of medical waste by private clinics.'' His colleague, Mr Wong, will raise the issue at the next Sai Kung District Board meeting in December. Ng Fong Siu-mei of Friends of the Earth said: ''This is alarming. We wrote to the Department of Health expressing our concern about medical waste being dumped on September 19 and have not yet had a reply. We want to know what is going on.'' The Government ordered an inquiry into the problem after the discovery of the used syringes at Shek O. Secretary for Health and Welfare Elizabeth Wong Chien Chi-lien promised that the whole question of medical waste disposal would be scrutinised. The Environmental Protection Department has also called for legislation.
