ABSTRACT

ve To explore the levels of boood lead of preschool children in Harbin and their impacts on the growth and development of children. Methods 310 preschool children aged 4~7 years were selected for measurement of height and weight, and for collection of fasting blood samples, determined for concentrations of lead by ICP/ MS assay.
