Measurement of blood‐lead levels in school children of Jeddah Saudi Arabia and assessment of sub‐toxic levels of lead on some sensitive hematological parameters

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.

This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. CAS# 7439-92-1
