Impacts

Ground-level ozone, often referred to as smog, is indeed a serious environmental issue in the United States and globally. It forms when pollutants emitted from vehicles, industrial facilities, and other sources react in the presence of sunlight.

Nitrogen dioxide (NO₂) is a harmful air pollutant primarily resulting from combustion processes, especially in vehicles and power plants. It is a significant component of nitrogen oxides (NOₓ) and contributes to various environmental and health issues

Indoor air pollutants are a major concern for lung health, as people spend a substantial amount of time indoors. These pollutants include a variety of particles, gases, and biological contaminants that can accumulate inside homes, offices, and schools, potentially leading to respiratory issues and other health problems.

Particle pollution, also known as particulate matter (PM), is a mixture of tiny solid and liquid particles suspended in the air. These particles can be made up of dust, dirt, soot, smoke, and chemical compounds. Particulate matter is indeed a significant air pollutant regulated by national air quality standards, particularly in the United States under the Clean Air Act.

Sulfur dioxide (SO₂) pollution is a major environmental and health issue primarily caused by fossil fuel combustion, industrial processes, and natural sources like volcanic eruptions. SO₂ is part of the sulfur oxide (SOₓ) group and can create both short- and long-term environmental and health hazards, affecting air quality.

Climate change has a significant impact on lung health through various pathways, including worsening air quality, increasing allergens, and contributing to extreme weather events. These effects exacerbate respiratory issues, increase disease susceptibility, and place additional strain on vulnerable populations, such as children, the elderly, and those with pre-existing respiratory conditions.
