About 1,000 people in Fengxiang county, Shaanxi province, who are to be relocated due to lead poisoning that sickened 615 children, may face a new threat of lead contamination, villagers said yesterday.

Some children who have lived close to the relocation site since 2004 showed high concentrations of lead in their blood as well, some parents told China Daily yesterday.

Dongling Lead and Zinc Smelting Factory is mainly to blame for the lead poisoning incident in Fengxiang, Shaanxi province, environment authorities said on Saturday.
