Lead poisoning: More than a medical problem

Abstract

Medical records of 236 Newark, New Jersey children hospitalized and chelated for lead poisoning in 1977 through 1980 were reviewed to determine whether or not any discernible progress had been made in eradicating the disease since 1972. Results show that the number of treated asymptomatic children, ages 1-6, began to rise after 1976 and was higher in 1980 than in 1972 when the Newark Lead Poisoning Prevention and Control Program first began. Although mean and peak blood lead levels have decreased over the nine-year period since 1972, signaling a lessening of disease severity, the increase in numbers and rates indicates that childhood lead poisoning still exists as an environmental and social problem.
