Thirty-nine residents of Kai Ching Estate in Kowloon City were found to have excessive amounts of lead in their blood following government tests, Secretary for Food and Health Ko Wing-man said.
In the second batch of residents who underwent blood tests, 39 of the 302 people saw their blood lead levels exceed the government’s reference value, Ko said in a media briefing on Tuesday.
Of the 39, 27 are children under six while the remaining 12 are mothers who breast-feed their babies.
Residents were told to stop drinking tap water from their apartments or using it for cooking. They were also advised to use the new water sources provided by the government.
Ko said the government has offered physical checks on the 27 children as their parents are worried about the mental and physical development of their kids.
Recent tests showed that the lead content in many water samples from Kai Ching Estate and several other public housing estates have exceeded the maximum level set by the World Health Organization.
Earlier, blood tests arranged by TVB for residents of Kwai Luen Estate found that a woman and her young son have high levels of lead in their blood. They have been living in the public housing estate for a year.
