...children in the study are participants in a broader long-term research project, begun in 1998, that follows them from shortly before birth to age 11. To determine prenatal exposure to PAHs and other pollutants, mothers of these children wore special backpacks containing air-sampling equipment for 48 hours during their third trimester of pregnancy, capturing both indoor and outdoor air quality. Based on the results, they were divided into high-PAH-exposure and low-exposure groups. The mothers were healthy, nonsmoking black and Dominican-American women, ages 18 to 35, living in northern Manhattan and the South Bronx...

Five years later, of course, the Soviet Union collapsed. But that threat - while it has yet to materialize - still lives on in the toolbox of those pressing Congress to spend real...
