Air pollution in London during the 19th century and early 20th century commonly caused the bricks to receive a sooty deposition over time, turning the bricks greyish or even black, but the removal of contaminants from the air following the passing of the Clean Air Act in 1956, has enabled older buildings to be cleaned and new buildings to retain their natural colour.

Asepsis, a state of being free from biological contaminants
The cytoplasm in the thin portion contains pinocytotic vesicles, which may play a role in the turnover of surfactant and the removal of small particulate contaminants from the outer surface.
