Many volatile organic compounds (VOCs) are present in the indoor air of Canadian homes, some of which may pose a risk to human health at certain exposure concentrations. Health Canada has developed exposure limits for a small number of VOCs which were prioritized for full assessments because they are commonly found in Canadian homes and have the potential to cause adverse health effects. To assist public health professionals, including those involved in standards development processes, who may need to assess the possible risk from exposure to other VOCs potentially found in indoor air, Health Canada has developed screening values called Indoor Air Reference Levels (IARLs).
