Abstract:
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.
