"NASCAR Races into Chicago Amidst Air Quality Concerns"

As Chicago grapples with dangerous air quality, NASCAR racecars are set to take to the streets of Downtown, raising concerns about exacerbating pollution. While NASCAR cars are generally unregulated and lack pollution mitigation devices, experts suggest that the short-term impact on air quality may not be as severe as anticipated. The emissions from the race, equivalent to the annual emissions of about five cars, pale in comparison to the daily emissions from over a million cars in the city. NASCAR has made efforts to reduce emissions by using a corn-based ethanol blend and has plans for recycling, hydration stations, and solar-powered light towers. However, experts advise caution for attendees, particularly those with asthma or comorbidities, as racecars emit volatile organic compounds that can cause smog and trigger health issues. It is recommended to check air quality before attending the race and take necessary health precautions.
