From benzene to BaP: the toxins strewn across Grenfell

High levels of noxious substances found in soil and on balconies in west London

The conclusions are stark. The fire that began in a single flat and engulfed all 24 storeys of Grenfell tower, killing 72 in the process, spread a cocktail of contaminants that may harm the health of residents, clean-up workers and emergency services for years to come.

The blaze released a plume of noxious gases including carbon monoxide and hydrogen cyanide. In that plume were fine particulates that damage the lungs, and known cancer-causing substances and irritants from benzene to polyaromatic hydrocarbons (PAHs).
