“…The potential health hazard of Pb additives in gasoline was foreseen in the 1920s (Rosner and Markowitz, 1985;Lippmann 1990) and the actual accumulation was empirically observed in the USA (Angel et al, 1975;Angle and Mcintire, 1982;Mielke et al, 1983;Earickson andBillick, 1988), New Zealand (Shcllshear et al, 1975), Britain (Thornton, 1990), and Australia (Day, 1977;Fergusson et al, 19RO).
