Environmental lead exposure to toll booth workers in Hong Kong
AbstractA survey of workers in the Lion Rock Tunnel toll booths was conducted, as they were regarded as a high risk group in lead exposure due to high density of vehicular traffic. The exposure of the workers to lead was determined by continuous sampling of air around the breathing zone of workers inside the booths. Blood lead concentration of 50 workers showed a mean of 0.65 μmol/L and the mean urine lead concentration was 0.14 μmol/L. Other tests, such as urinary amino-levulinic acid (ALA), erythrocyte zinc protoporphyrin (ZnPP) and haemoglobin concentration (Hb), were also performed. The blood lead concentrations and other biological parameters of the toll-booth workers were acceptable and may be attributedd to the recent legislation to lower the lead content in petrol and to the good preventive measures taken by the management.
