Assessment of lead toxicity in traffic controllers of Alexandria, Egypt, road intersections

Journal Article · · Arch. Environ. Health; (United States)
Blood lead level (BPbL) was determined in forty-five traffic controllers working on Alexandria road intersections. Central nervous system dysfunction in the subjects studied was investigated by means of performance tests. Biochemical indicators related to lead exposure such as delta-aminolevulinic acid dehydratase and hemoglobin in their blood were also determined. Results indicated that most of the subjects studied have a comparably high BPbL. They also showed significantly poorer performance scores than that obtained in a previous study with a group of textile workers of the same age and educational levels. The mean of the BPbL in the traffic controllers was found to be 68.28 +/- 13.22 micrograms/dl. This is a very high level compared to an acceptable level of 30.00 micrograms/dl. All neurobehavioral symptoms demonstrated in the traffic controllers could be attributed to a high level of lead exposure.
