weight, body surface area, inhalation rates, ingestion of dust and soil, and drinking water consumption to ensure consistency of approach. Values that are used are representative of the Canadian general population. Exposure is estimated separately for different age groups because of physiological and psychological differences that may affect exposure.

Health Canada and the University of Windsor collected 24-hour personal, indoor, and outdoor exposure samples for 188 polar and non-polar volatile organic compounds (VOCs). A total of 100 study participants in Windsor, Ontario were followed over two 1-year periods. Sampling took place in 8-week winter and summer periods of 2005 and 2006. In 2005, five consecutive 24-hour VOC sampling measurements were obtained to represent indoor, outdoor, and personal exposure levels.
