چکیده
Nations around the world have banned lead in petrol [1]. The primary reason for removing lead additives from petrol is its adverse effect on human health. In response to evidence that blood lead concentrations approaching toxic levels in children and traffic policemen in Sri Lanka, tetraethyl lead was removed from petrol in the year 2002. Following this change a reduction in roadside atmospheric lead by 81.5%, 82% and 84% has been demonstrated at three locations in Colombo [2]. We report on blood lead levels of children before and after the discontinuation of leaded petrol.
