Prediction of Pediatric Blood Lead Levels From Gasoline consumption

摘要

Tables illustrate the results of a study which analyzed the relationship between blood levels in children and gasoline lead consumption in New York City, Chicago, and Louisville. It examined the percent of blood lead measurements which exceeded 30 micrograms of lead per 100 milliliters of blood, a level which the Environmental Protection Agency has concluded is the maximum safe level. Tables provide data on the blood lead levels, by race, age group, and sampling data for all three cities. The New York City data are separated by screening status as well. The blood lead levels are reported both as geometric mean blood lead, for the given cell, and the percent of observations with blood leads greater than 30 micrograms of lead per 100 milliliters of blood. To illustrate the time dependence of the blood lead, plots have been made for a single age - race population for all three cities. The 24 - 35 year old age group was selected since this appears to be the most sensitive group. Tables summarize data base characteristics and the number of observations for each city, broken down by race. Gasoline data are appended.
