Incense / Bukhour smoke (burned)
دخان البخور (محروق)
FORMAT / emission reference · CAS: n/a (format)
The smoke is the issue - ventilate, limit, keep kids & asthmatics clear
Why this verdict
Strongest negative in the category. Smoldering incense emits very high fine particulate (reported well above cigarette PM per unit burned), plus benzene, aldehydes (formaldehyde/acrolein) and PAHs; associated with respiratory and carcinogenic risk. Heavy/regular unventilated indoor use trends toward 'avoid'.
What It Is
Burning bukhour, oud or incense releases a smoke that is itself the main exposure - far more than whatever scent is on the label.
Here's the fact the label never tells you: burning incense indoors is one of the strongest sources of fine-particle air pollution in a home - per unit burned it can exceed cigarette smoke for particulates, and it carries benzene, formaldehyde and PAHs. You don't have to give up bukhour - but open a window, keep it brief, and keep babies, pregnant women and anyone with asthma out of the smoke.
