Abstract
Since 1979 is it known that the lead exposure, which is held harmless for adults, can occur severe behavioral disorders, mental performance and concentration decrease in children and therefore it was necessary to reduce the environmental lead exposure. In Hungary in the mid-1980s the lead content of petrol were progressively reduced. The first specific study on blood lead level of children was carried out in the years 1985 and 1986, and it showed a significant difference between children living in city center and outer districts in Budapest. The significance between blood lead level and lead concentration in air was stronger in children than in adults. In the early 1990s our studies showed, that blood-lead level was still above 10-g/dL in 8–13% of urban children, higher than 20 g/dL blood-lead levels were measured only sporadically. Seven years after the introduction of unleaded petrol the average blood-lead level of children was significantly lower, between 1996 and 2006 is the difference more than 60%, however our studies showed also, that petrol lead content is not the only exposure source affecting the blood-lead level. In the next decade is expected moderate elevated blood-lead level in children, which reminds us to reduce the environmental lead pollution.
