Hamilton residents are dealing with heavy soot deposits covering homes, cars, and outdoor surfaces, with 475 complaints filed to Ontario's Ministry of the Environment over nine days. The black carbon, produced by incomplete combustion of carbon-based fuels, is suspected to come from north-end industrial facilities including steel mills and chemical plants. Residents report staying indoors, buying HEPA air purifiers, and avoiding outdoor activities due to health concerns. McMaster University researchers warn that fine soot particles can travel deep into the lungs, causing inflammation and worsening conditions like asthma. The Ministry is collecting samples but has not yet identified the source. Local MPP Robin Lennox is pushing for answers as the community demands action on industrial emissions that have become a regular nuisance in the area.
