title: Lead in children's hair, as related to exposure in Tarragona Province, Spain.
abstract: Concentrations of lead were determined in the hair of 478 school children living in an industrial and an agricultural area of Tarragona Province, Spain. The influence of age, sex, hair colour and family occupation on the children's hair lead concentration was also evaluated. Girls had more lead in their hair than boys (10.54 vs 6.55 micrograms g-1), and the lead levels decreased with age. Lead concentrations in hair with respect to hair colour decreased in the order red, blond, brown, black. Family occupation was one of the most significant factors influencing the lead content of children's hair. Although the average lead content was higher in the industrial area (9.38 micrograms g-1) than in the agricultural area (7.80 micrograms g-1), this difference was not statistically significant.
