Exposure to high level of nitrogen dioxide may lead to inflammation of the mucous membrane and the lower and upper respiratory tracts. [11] The symptoms of acute nitrogen dioxide poisoning is non-specific and have a semblance with ammonia gas poisoning, chlorine gas poisoning, and carbon monoxide poisoning.

[86] [87] High ozone concentrations irritate the lungs and thus affect respiratory function, especially among people with asthma. [81] People who are most at risk from breathing in ozone air pollution are those with respiratory issues, children, older adults and those who typically spend long periods of time outside such as construction workers ...
According to the American Lung Association, the Denver–Aurora area is the 14th most ozone-polluted area in the U.S. [65] The problem of high ozone levels is not new to this area. In 2004, the EPA allotted the Denver Metro /North Front Range [ b ] as non-attainment areas per 1997's 8-hour ozone standard, [ 66 ] but later deferred this status ...
The weather service and state DEM provide some tips on avoiding health problems due to heat and bad air.
Of the 35 counties in Florida with monitors for ozone or particle pollution (as chosen by the state and the EPA), nearly all of them received an A grade for high ozone days in the years 2020-2022.
The measurement is based on the observed relationship of nitrogen dioxide (NO 2), ground-level ozone (O 3) and particulates (PM 2.5) with mortality, from an analysis of several Canadian cities. Significantly, all three of these pollutants can pose health risks, even at low levels of exposure, especially among those with pre-existing health ...
Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [61]
