Water samples from four more housing estates found tainted

Water samples at four more public housing estates in Hong Kong were found to contain excessive levels of heavy metals, including lead and nickel, RTHK reported.

The findings came after government tests Wednesday confirmed that 39 residents of Kai Ching Estate in Kowloon City have excessive amounts of lead in their blood.

Among 74 water samples taken from faucets at 13 public estates, one from Kwong Fuk Estate in Tai Po was found to contain 343 milligrams of nickel per liter of water, higher than the 70 milligrams recommended by the World Health Organization (WHO), according to the Democratic Party, which organized the tests.

One sample from Yue On Court in the Southern district and another from Siu Hong Court in Tuen Mun also contained excessive nickel.

A sample from Lei Tung Estate in the Southern district was found to contain 12 milligrams of lead per liter of water, compared with the upper limit of 10 milligrams set by WHO.

Democratic Party legislator Helena Wong Pik-wan said investigations revealed that all of the four estates saw their water pipes replaced not long ago.

She urged the Consumer Council to publicize information on metals contained in water faucets that are currently on store shelves, as well as other related data.

Ming Pao Daily quoted an obstetrician, Dr. Louis Chan Yik-si, as saying that high level of lead in blood could affect sperm count in men and delay the arrival of puberty for females.

A woman could also face higher risk of infertility should she have a blood lead level higher than 12 milligrams.

People should drink more water and consume more calcium to help discharge lead from the system, Chan said.
