Exposure to NO2 has been linked to a range of health issues, including increased risk of heart disease, aggravation of asthma and other respiratory conditions, and impaired cognitive function.

Major sources of NO2 emissions include motor vehicles, power plants, and industrial activities such as manufacturing and mining.

Diesel particulate filters are primarily designed to reduce emissions of particulate matter, not nitrogen dioxide.

The current NAAQS for NO2 in the United States is 53 parts per billion (ppb), averaged over a one-hour period.

All of the options listed are potential consequences of exceeding the NAAQS for NO2.

NO2 undergoes photolysis in the presence of sunlight, releasing nitrogen monoxide (NO) and atomic oxygen (O), which can then react with other compounds to form O3.

While NO2 has been linked to increased risk of cardiovascular disease and reduced lung function, there is no strong evidence suggesting a link between NO2 exposure and lung cancer.

NO2 acts as a greenhouse gas, an oxidizing agent, and an aerosol precursor in the atmosphere.

While renewable energy sources can help reduce overall air pollution, they are not specifically targeted at reducing NO2 emissions from power plants.

Nitrification is the process by which NO2 is oxidized to form nitrate (NO3-) in the atmosphere.

All of the options listed are potential environmental impacts of NO2 emissions.

NO2 emissions are regulated to protect human health, the environment, and visibility.

All of the options listed are potential strategies for reducing NO2 emissions from industrial activities.

Reduction is the process by which NO2 is converted into NO in the atmosphere.

All of the options listed are potential benefits of reducing NO2 emissions.
