Low lead level in teeth in Israel.
A total of 180 sound teeth extracted from people living mainly in Northern Israel and some in the center of the country, aged 14-75 years, were analysed by graphite furnace atomic absorption spectrophotometer. The average lead level in teeth roots ranged between 1.61-25.72 micrograms/g dry root, according to the donor's age. This low level was measured in all the regions which were checked, with no significant differences between them, despite differences in levels of motor traffic rates. Based on the low lead level in teeth, we assume that no further reduction in the lead level in gasoline is needed, as long as motorization rate or gasoline consumption does not change significantly.
