Meet Archishman Dey, 8th grader who found incense caused most pollution
Ohio eighth-grader Archishman Dey investigated how everyday household activities affect indoor PM2.5 pollution. Testing an air fryer, candle, humidifier, natural gas and incense, he found incense produced the highest average levels, followed by the air fryer. Inspired by concerns about his grandparents’ asthma, Archishman hopes his findings encourage families to improve indoor air quality.
Eight-grader Archishman Dey from Solon, Ohio, is drawing attention to a surprising source of indoor air pollution - the air inside our homes. In a science project, he examined how everyday household activities impact levels of PM2.5, fine particles smaller than 2.5 micrometres in diameter. Archishman discovered that burning incense sticks generated the highest levels of PM2.5 among five common household sources tested: an air fryer, candle, humidifier, natural gas stove, and incense.
