title: [Pb pollution on surfaces in a typical coking plant and health risk assessment].
abstract: Pb pollution on the surfaces of buildings and devices at a coking plant was studied. The objectives of this study were to determine the Pb content and its spatial variation on the surfaces, and to assess the potential health risk from this Pb. Ninety-four wipe samples were collected from 56 buildings and devices at the coking plant, and their Pb contents were determined. Surface Pb concentrations ranged from 0-538 micro x g/dm2, and concentrations in 78.7% of the samples exceeded the US Department of Housing and Urban Development (HUD) standard (2.69 microg/dm2). By area, the proportion of samples with concentrations greater than the US HUD standard were 78.9% in the office and living zone, 75.0% in the refining zone, 73.7% in the coking zone and 78.6% in the coke-gas zone. Among the various types of surfaces, the coke pusher had the highest average surface concentration of Pb. The average surface concentrations of Ph on common coking plant surface materials followed the order paints > brick > cement > glass, and the concentrations in 94.4% of the wipe samples taken from paint surfaces exceeded the US HUD standard.
