  1. Lead exposure in the lead-acid storage battery manufacturing and PVC compounding industries.

    Article - En anglais

    This study was conducted as part of the Human Exposure Assessment Location (HEAL) Project which comes under the United Nations Environment Programme/Worlc Health Organisation (UNEP/WHO) Global Environmental Monitoring System (GEMS).

    The objective of the study was to evaluate workers'exposure to lead in industries with the highest exposure All subjects were interviewed about their occupational and smoking histories, the use of personal protective equipment and personal hygiene.

    The contribution of a dietary source of lead intake from specified foods known to contain lead locally and personal air sampling for lead were assessed.

    A total of 61 workers from two PVC compounding and 50 workers from two lead acid battery manufacturing plants were studied together with 111 matched controls.

    In the PVC compounding plants, the mean lead-in-air level was 0.0357 mg/m3, with the highest levels occuring during the pouring and mixing operations.

    This was lower than the mean lead-in-air level of 0.0886 mg/m3 in the lead battery manufacturing plants where the highest exposure was in the loading of lead ingots into milling machines.

    Workers in lead battery manufacturing had significantly higher mean blood lead than the PVC workers (means. 32.51 and 23.91 mcg/100 ml respectively), but there was poor correlation with lead-in-air levels.

    Among the lead workers. the Malays had significantly higher blood lead levels than the Chinese (mean blood lead levels were 33.03 and 25. (...)
