Служба национальных парков планирует рекордный салют к 250-й годовщине, вызывая опасения по поводу качества воздуха
Служба национальных парков планирует запустить более 850 000 фейерверков над Вашингтоном, округ Колумбия, к 250-й годовщине страны, что заставило чиновников здравоохранения предупредить о потенциально опасном загрязнении воздуха и рекомендовать защитные меры.
The National Park Service intends to fire more than 850,000 fireworks over Washington, DC, as part of celebrations for the United States’ 250th anniversary, a scale roughly 100 times larger than the previous year’s display. Internal agency documents indicate the show could elevate particulate pollution on and around the National Mall to levels deemed hazardous.
A draft air-quality analysis obtained by Politico recommends that people avoid prolonged exposure and consider wearing N95 respirators when outdoors, although no federal agency has announced an official masking recommendation. The Environmental Protection Agency stated that monitoring the fireworks’ impact is not within its responsibilities.
Researchers cite a 2023 New York study showing that July 4 fireworks can raise fine-particle concentrations from typical levels below 15 micrograms per cubic meter to over 1,000, and in some cases as high as 3,000, far exceeding federal standards. While pollution usually dissipates within a day, ongoing heat and drought conditions may slow dispersion and allow contaminants such as perchlorates and heavy metals to persist in the Potomac River, potentially affecting fish, amphibians and nesting ospreys.
Health organizations advise vulnerable individuals to watch the display from a distance, remain indoors with windows closed and air filters operating, or use N95 masks. > "With more fireworks comes more health risks," said Laura Kate Bender of the American Lung Association.
