Occupational lead toxicityin battery workers
Objective: To estimate blood lead level (BLL) and to assess the features of lead toxicity among lead acid battery (LAB) industrial workers.
Methods: This prospective study was carried out in the medical centre of PCSIR Laboratories, Karachi from March 2012 – March 2013. Fifty LAB industry workers, males and females between 17-65 years were included in the study. They were divided into group 1 with 40 workers- directly related and group 2 with 10 workers –indirectly related, (administration staff members) to LAB manufacture. Detailed history, complete physical examination and BLL estimation by flameless atomic absorption spectrophotometer was done.
Results: Total 34 patients in group 1 and 3 patients in group 2 had elevated BLL. Comparison of group 1 and 2 revealed anemia (40v/s4), bone pain (38v/s7), abdominal pain (38 v/s 2), nausea (32v/s6), head ache & irritability (24v/s6), weakness & lethargy (21v/s6), tremors (13v/s0) insomnia (5v/s4), lead line (4v/s 0) and blood pressure above 140/90 mm of Hg (12v/s0) respectively.
Conclusion: High blood lead level and features attributable to lead toxicity were prevalent among LAB industry workers of Karachi.
