Comorbidities are two or more diseases existing at the same time in the body. They are common for people with COPD because organ systems work differently when they do not receive enough oxygen. When a resulting condition occurs, it can be considered comorbidity.

Particulate matter can include sediment -. especially clay and silt, fine organic and. inorganic matter, soluble colored organic. compounds, algae, and other microscopic. organisms.
