This should have been intuitive and not surprising : any
chemical that uses its powerful biologically destructive effect,
ie. most bleaches employ strong oxidizing agents such as sodium
hypochlorite aka sodium chlorate(I) for its bleaching, cleaning,
disinfecting functions, will most certainly have similarly
destructive effects on the human biological body.
Many restaurants in Singapore use bleach to wipe tables and mop
floors even when customers (eg. myself) are present and still
eating, the bleach smell has always nauseated me and I've always
intuitively known there would be harmful damaging biological
effects, even on customers with occasional exposure, let alone
clueless, hapless and helpless employees using the bleach (similar
to some pitiful employees working under installed UV lightings at
their workplace, eg. Singapore Zoo / Night Safari, without
realizing the carcinogenic DNA damage UV light causes, which is
also why you should get your anti-cancer Vitamin D from supplements
rather than from sunlight exposure, no thanks to ozone layer
depletion).
Regularly using bleach linked to higher risk of fatal lung
diseases such as COPD
