||Evaluation of preventive and control measures for lead exposure in a South African lead-acid battery recycling smelter
||Oct. 2007, Vol.4, No.10, p.762-769. Illus. 8 ref.
||This cross-sectional study investigated the effectiveness of preventive and control measures implemented in a South-African lead smelter involved in the recycling of lead-acid batteries. Twenty-two workers were observed and interviewed. Structured questionnaires were used to gather workers' personal information, perception about their work environment, health risks and work practices. Retrospective data from air monitoring and medical surveillance programs were obtained from the plant's records. Although the plant had adopted several control measures, some areas had average lead-in-air levels above 0.15mg/m3, the occupational exposure limit for lead. Workers in the smelting area and battery breaking area had the highest blood lead levels. Personal protective equipment was not in regular use in lead exposure zones.
