| Popis: | Road sweepers are especially exposed to environmental pollution. This study investigates the lead exposure, urinary delta-aminolevulinic acid concentration (ALA) and haematological parameters of road sweepers working in traffic-congested areas of Bangkok. One hundred and ninety-four apparently healthy road sweepers aged 20-59 years were investigated. One hundred and thirty-nine staff from an academic institution served as controls. Both male and female road sweepers had slightly, but significantly, lower mean corpuscular haemoglobin concentration (MCHC) values. The white blood cell count (WBC) in female road sweepers was significantly higher compared with the female controls. The proportion of reticulocytes was higher in male and female road sweepers compared with the controls, while no difference was found in blood lead levels and ALA between male road sweepers and controls. Female road sweepers had slightly higher blood lead levels compared with the controls. ALA was no different between both groups of ... |
