With wildfire smoke and pollution, some want end to neighborhood fireworks: ‘It should be a no-brainer’
People watch from Navy Pier in Chicago as fireworks are set off on July 1, 2023, to celebrate the 4th of July weekend.
“I walked around the neighborhood and looked at the bluish haze and fog in the air thinking, ‘Can’t be good for you,’” he said. Fireworks also emit particles small enough to enter the bloodstream and lungs, known as PM2.5. This is the same type of particle pollution that triggered the air quality alert last week, when PM2.5 levels reached a point that was dangerous for the general public, not just sensitive groups like those with asthma.Chicago’s air quality: ‘We’re in the crosshairs.’ Wildfires and wind push region’s air to worst in the world, global pollution index shows.
In terms of what they’re made of, fireworks contain certain types of metals that produce vibrant colors when ignited. For example, copper makes the color blue and is one of the more toxic metals, Verma said. “We have found that although it is a very short-term source, it actually has a very, very, very high toxicity of the particles emitted,” Verma said.People that are the most at risk for health effects from PM2.5 are children and those with respiratory or heart issues,Background levels of PM2.5 are also different across Chicago neighborhoods, consistent with previous research showing how communities of color are disproportionately impacted by air pollution.
