Detailed explanation-1: -Longer exposures to elevated concentrations of NO2 may contribute to the development of asthma and potentially increase susceptibility to respiratory infections. People with asthma, as well as children and the elderly are generally at greater risk for the health effects of NO2.
Detailed explanation-2: -Elevated levels of nitrogen dioxide can cause damage to the human respiratory tract and increase a person’s vulnerability to, and the severity of, respiratory infections and asthma. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease.
Detailed explanation-3: -nitrogen dioxide(NO2), a byproduct of oxidation and combustion, is a primary outdoor and indoor air pollutant (14). Because of its oxidative potential and limited solubility, NO2 is a deep lung irritant, and accidental exposures to high concentrations can cause acute lung injury and death (13, 49).
