Canadians are indoor creatures who spend 90% of their time inside buildings and almost 70% of their time in their homes. Consequently, most exposure to air pollution, and associated health impacts, originates indoors. Particulate matter generally has been identified as one of the most serious indoor contaminants. Nanoparticles (broadly defined here as particles less then 50 nm in diameter) are of particular scientific and practical importance because of the relative lack of exploration of their concentrations and dynamics in indoor environments, as well as because of their serious health impacts including asthma and other respiratory diseases, cardiovascular diseases, and lung cancer. Statistically, over 95% of airborne particles are nanoparticles, but they have not commonly been studied indoors. Indoor nanoparticles are generated by a broad range of sources such as heated surfaces, cooking, combustion, chemistry, as well as emissions from manufactured nanomaterials. Therefore, identification of indoor airborne nanoparticles and control technologies is critical for the protection of Canadian public health.

加拿大人是室内生物，90%的时间在建筑物内度过，近70%的时间在家里度过。因此，大多数暴露于空气污染以及相关的健康影响都源于室内。颗粒物通常已被确定为最严重的室内污染物之一。纳米颗粒（此处广义定义为直径小于50 nm的颗粒）具有特别的科学和实践重要性，因为相对缺乏对其在室内环境中的浓度和动力学的探索，以及因为其严重的健康影响，包括哮喘和其他呼吸道疾病，心血管疾病和肺癌。据统计，超过95%的空气中的颗粒物是纳米颗粒，但它们通常没有在室内进行研究。室内纳米颗粒是由广泛的来源产生的，例如加热表面，烹饪，燃烧，化学以及人造纳米材料的排放。因此，室内空气中纳米粒子的识别和控制技术对保护加拿大公众健康至关重要。
