Cleaning floors with bleach significantly alters indoor air chemistry

“When we wash with bleach, the oxidation occurs not only on the surface we are washing but everywhere else too”. Carslaw agrees, adding that bleach washing produces a much “wider group of chemicals than previously thought”, and that “chemists need to work much more closely with toxicologists” in order to determine the health impacts of the resulting, chemically-altered air.

How dampness in homes impacts indoor air pollution

US researchers are exploring to what degree dampness in homes alters the chemistry and composition of the indoor air. The chemicals formed on wet indoor surfaces could be partially responsible for the increased respiratory symptoms seen in damp homes, an effect that has never been fully explained by mold and mildew.
