    The combustion from large #fireworks displays typically causes significant #pollution because it generates fine particulate matter, also known as PM2.5. These small particles can penetrate deep into the #heart & #lungs, causing irritation & in some cases #asthma attacks & other illnesses.

    A draft #air-quality analysis, based on the #NPS’s modeling, states that people should “avoid prolonged exposure” to the pollution around the Mall.

    The #Interior Dept & the #NPS did not respond to questions about the documents & #pollution associated with the event.​
    
In downtown #DC, #Arlington & the #CapitolHill area, where pollution will be “very unhealthy,” the document says that people should “expect irritation symptoms” & limit their postshow exposure to the pollution. It projects that pollution will remain at elevated levels for 3 to 6 hours after the show.

    Levels of up to 1,200 micrograms per cubic meter match what have been recorded with other #fireworks events but are nevertheless reason to take precautions, said George Thurston, a professor of medicine & population health at NYU. He added that the worst-case scenario would exceed anything he has seen previously recorded from pyrotechnic displays.

    “People should use the precautionary principle, which is to minimize exposures,” Thurston said. “An N95 mask would be a good idea.”

    He said that research on #air #pollution focuses on cars, power plants & other sources but is lacking on the #health effects of #fireworks-related pollution, as it often passes quickly.
    
Fireworks contain metals, such as copper, that help to create their vibrant colors but are hazardous to breathe when they enter the air….

    People with #respiratory conditions can stay inside during the #fireworks display & wait for the wind to blow away the smoke, he said.

    #NPS, in a separate document, similarly said that people should “wear an n95 mask when outdoors” & “remain indoors as much as possible during & after the show.”
    
Another internal document designed to take demographics in the area into account advises NPS staff to “not treat race, ethnicity, income, disability, age, or language as risks by themselves.”

    The #fireworks are planned to be set off at sites along the #PotomacRiver & the #NationalMall, not far from areas such as Southeast Washington that are predominantly #Black & #LowIncome.

    Thurston said there is a greater prevalence of #respiratory & #cardiovascular problems, including #asthma, in lower-income & minority populations.
    
“I definitely think that should not be ignored,” he said.

    @LockEx

    Gross. I don’t understand fireworks. They scare the hell out of all the animals & make us sick. I like the floating lanterns. And now you can use drones for a light display.

    @Nonilex I was trying to understand how this relates to AQI for some personal experience context. Using the AirNow.gov AQI calculator, a worst case scenario of 2,000 micrograms per cubic meter for 6 hours (and assuming an average of 10 micrograms for an urban area during the rest of the 24 hour period required for the calculation) could equal 1859 on the index which is (being over 300), of course, hazardous.

    I honestly had no clue fireworks could be as noxious as some of the worst wildfire impacts.

    Disclaimer: I’m not a climate scientist nor a mathematician but I did my best to understand the relationship between these two measurements. I welcome any corrections to my math.

    @Nonilex "a roughly 40-min show….Trump will speak as part of the event"

    So what you're saying is this will be a 4-hour pollution event?
