...they always have been, fireworks are handcrafted. Computers may trigger the bursts and create complex "choreography," but the basic recipe for many fireworks has remained unchanged for a hundred years: potassium nitrate or perchlorate; sulfur, charcoal or aluminum; plus assorted chemicals to produce varied hues. "With all the space-age advances," says Dave Oppermann, a "play-by-play" commentator, "they're still making fireworks much the way they have for hundreds of years."

Despite the tons of lead, sulfur dioxide and other combustion products filtered from the atmosphere, millions of Americans suffer from pollution-related breathing disorders, including asthma and bronchitis. In 1993 the American Lung Association sued the Environmental Protection Agency to make it re-evaluate its standards for particulates--very fine dust particles (about one twenty-fifth the diameter of a human hair)--after studies showed that they can lodge deep in the lungs and may contribute...
