[Assessment of lead blood levels in children living in Lucca (Italy) in 1993. The study was conducted as part of the project METOS, in accordance with the decree 496 of June 1982 which adopted the directive CEE No.77/312].
OBJECTIVE
Lead poisoning is a major cause of environmental concern in all countries worldwide. Saturnism in children, especially if young and neglected, represents a peculiar phenomenon both in terms of the biology of growing subjects and the epidemiological nature of poisoning. In under five-year-olds, in addition to lead levels in the atmosphere, it is equally important to evaluate the presence of contaminated dust in the house, hand-to-mouth activities and the level of care provided by parents. It has been demonstrated that, in the presence of equivalent environmental lead levels, dust removal from the house and prevention of hand-to-mouth activities can successfully reduce lead blood levels (PbB) in children.


OBJECTIVE
The aim of this study was to evaluate the risk of chronic lead poisoning in children attending Local Health Unit 6 in Piana di Lucca and to assess the need for a possible health education campaign aimed at eliminating the specific pediatric risk for lead poisoning.


METHODS
Assay of lead blood levels in 172 children from 0 to 14 years old consecutively attending the Emergency Ward at Campo di Marte Hospital in Lucca for reasons not relating to lead poisoning.


RESULTS
Mean lead blood levels in children were 57.2 +/- 30.2 mg/l (mean 50 mg/l) without significant differences between the various age brackets (0-5, 6-10, 11-14 years old). Only one child presented pathological PbB levels (280 mg/l when first measured; 360 mg/l a few months later with normal values of erythrocytic Zn-protoporphyrin, 24-h urinary lead excretion and 24-h urinary delta-aminolevulinic acid). An epidemiological study is now being made of the causes. The general population within the same area presented mean PbB levels of 70.4 +/- 36.9 mg/l (mean 60 mg/l), measured in a total of 471 subjects (adults and children).


CONCLUSIONS
The PbB levels currently found in children resident in Lucca confirm a low-risk environmental situation. Preventive measures specifically aimed at children do not therefore appear to be justified at present.
