The hidden toll of July Fourth fireworks



The authors also showed that fireworks smoke may be creating an additional—albeit short term—health risk for communities already disproportionately burdened by air pollution: Urban ones with higher rates of asthma, more older residents, and a greater percentage of children under 10. These areas also tended to have more Black and Hispanic residents than those with less Fourth of July air pollution.
The high-risk communities identified in the study have “perpetual exposure to hazardous environmental toxins,” says Aisha Dickerson, an environmental epidemiologist at Johns Hopkins University who wasn’t involved with the paper. “This aggravates an already prevalent and persistent issue.”
