Final answer:
Pollutants that hang on to air particles in the troposphere include particulate matter and ground-level ozone, among others, and can cause serious health and environmental issues.
Step-by-step explanation:
The air pollutants that can be present and hang on to air particles in the troposphere include particulate matter, ground-level ozone, carbon monoxide, sulfur oxides (SOx), nitrogen oxides (NOx), and lead. These pollutants are known to cause various health and environmental issues, including property damage. Particulate matter is made up of tiny particles such as acids, organic chemicals, metals, and soil or dust particles that can be inhaled into the lungs and cause serious health effects. Ground-level ozone is not released directly into the air but is formed by reactions between NOx and VOC in the presence of sunlight, leading to health problems and damaging vegetation and ecosystems.
