Excessive lead levels were found in a water sample collected from a restaurant-grade stainless steel water boiler installed at a nursery school a month ago. Management of the Hong Kong Christian Kwun Tong Nursery School said that the boiler has only been used to sterilize utensils for the past two weeks. Samples of drinking water were found to be safe. There are no plans to run blood tests for schoolchildren. Lead levels in the boiler sample were about 10 times higher than the standard set by the World Health Organization. Principal Patricia Tang Ming-wai said she was puzzled by the finding. She said screws, instead of soldering metal, had been used in the pipes' joints. Licensed plumber Hugo Kan Kwok-leung said further tests would be necessary to identify the source of the lead - which might be inside the water boiler.Tianjin food is tested safeThe Centre for Food Safety has tested 40 samples of food from Tianjin after the explosions of dangerous chemicals in August.
