    A residue layer in the lungs is typically due to exposure of airborn substances that are too large molecularly to be absorbed into the bloodstream. Examples are tar from tobacco smoke, silicate dust from working in mines, and asbestos fibres, from working with asbestos over prolonged periods.

    Depending on the adhesive quality of the inhaled substance, it can be difficult to impossible to expel substances from the lungs.

    Substances adhering to the inside of the lungs block absorption of oxygen, and reduce the efficacy of the lungs, making breathing more labored and difficult.
