Observing fireworks is dangerous not only for burns, but also for respiratory diseases - this is the conclusion made by researchers from the US National Oceanic and Atmospheric Administration.
On Independence Day, July 4, the largest and most massive fireworks are launched in the United States. According to scientists, they are not only pleasing to the eye, but also pose a danger to the respiratory tract.
Diane Seidel, an employee of the National Oceanic and Atmospheric Administration of the United States, together with trainee Abigail Birnbaum, conducted a study, during which it turned out that during the fireworks, the atmosphere is filled with fine particulate matter PM 2.5. By measuring the air quality every July 4 from 1999 to 2013, the researchers were able to calculate even the average size of such particles: they reach 2.5 microns in diameter. Directly on the day of the mass launch of fireworks, according to measurements, the amount of fine particles in the air increases by 42%.
Microscopic particles enter the lungs through the respiratory tract and can cause coughing, shortness of breath, asthma attacks, heart attacks, strokes and even death of people with diseases of the lungs and liver, scientists stated.
