Sarnia Chemical Plant Halts Operations Amid High Benzene Emissions




A chemical plant near the Aamjiwnaang First Nation in Sarnia has temporarily ceased operations following the detection of dangerously high levels of the carcinogenic substance benzene. INEOS Styrolution, the company responsible, confirmed the halt on Saturday, citing maintenance and mechanical issues. This action comes after benzene levels were recorded at 115 micrograms per cubic meter on April 16—vastly exceeding Ontario’s annual average limit of 0.45 micrograms per cubic meter. The shutdown, which was not previously scheduled, follows reports of illness among the First Nation's residents and provincial orders demanding the plant address these emissions. The company has pledged to prioritize community and employee safety, and it is under investigation by both provincial and federal environmental authorities.
