Fireworks and Respiratory Conditions

Fireworks and Respiratory Conditions

Fireworks displays may be spectacular, but the particles shot into the atmosphere can be dangerous to your health. To produce different-colored flashes, many fireworks contain metal salts—for example, strontium for red and barium for green. Austrian researchers who tested samples of fallen snow before and after a New Year’s fireworks display found that the snow’s barium content increased some 500-fold. Since barium poisoning causes constriction of the airways, researchers say that inhaling the smoke from fireworks could aggravate respiratory problems, such as asthma.
