Abstract
Abstract Hair‐Pb concentrations in 200 school boys from the city of Jeddah, Saudi Arabia, aged 6–8 years in 1984, were first measured five years ago in 1984, as part of a program to evaluate the environmental impact of the gigantic developmental activities started a decade ago and now reaching their peaks in this Kingdom. After a period of five years, 93 of the same boys could be traced and were followed up in 1989 to see the effect of the intervening period. An interesting result emerged : the mean hair‐Pb concentration actually decreased from the 1984‐value of 8.88 ppm ( n = 93 ) to 7.30 ppm in 1989. This decrease can be attributed to a concurrent reduction in the lead content of gasoline used in Jeddah —‐ from 0.84 g per litre in 1984 to 0.60 g per litre in 1989, indicating a possible correlation between the hair‐Pb and the gasoline‐Pb levels.
