Rates of respiratory tract infections for children living in remote First Nations communities the Sioux Lookout Zone Northwestern Ontario are elevated and associated with poor indoor environmental quality including high exposures to endotoxin serious dampness mould damage. The studies also revealed a prevalence cigarette smoking most houses have wood stoves, variable quality. Depending on structure, polycyclic aromatic hydrocarbons (PAH) carcinogens, immunotoxins and/or inflammatory mediators that byproducts incomplete combustion organic materials. Indoor sources PAHs include tobacco smoke, cooking, burning fossil fuels house heating. Twelve were measured <300 µm fraction settled dust by GC-MS 59 houses. Nine detected all houses, median concentrations individual ranged from 66 804 ng/g. smoke dominated PAH profile. Limiting indoors upgrading low emission airtight stoves would improve air health this region Ontario.
