    Abstract:
    In order to study the effects of low-level lead exposure on neurobehaviour development, the neurobehaviour functions in eighty-five 1-3 year-old children were assessed by Neurobehaviour Psychological Test (recommended by the Institute of Psychology, Chinese Academy of Sciences). The results showed that the increase of blood lead (BPb) level in each 100 micrograms/L was associated with an average loss of 3-4 points of Development Quotient (DQ) in these subjects. Age, hand-mouth habits and environmental lead pollution are the main risk factors. It is concluded that even in a low-level lead exposure, DQ in young children may be affected. Certain intervention steps based on the levels of lead exposure were recommended.
