Based on aerosol measurements carried out in a test room, particle regional respiratory doses have been estimated for both combustion and non-combustion aerosol sources currently encountered in domestic environments. The general population chronically receives doses that, pooled together, are well above those due to urban outdoor pollution. At the end of each source operation, from 75% to 99% and from 27% to 93% of these doses are due to ultrafine particle, respectively on particle number and surface area metrics. Depending on the source, the pattern of exposure may be, for very short time laps, very intense (up to 8.0 × 10⁹ particles s⁻¹) and involve a fraction of particles with mode at about 10 nm. For appliance operated by brush electric motors, this mode is the major one and is due to the generation of copper nanoparticles. The health relevance of such particles deserves particular attention due to their possible translocation to the brain and in the light of the associations between copper ions and Alzheimer's disease, proposed by several studies.

根据在测试室中进行的气溶胶测量，已估算出目前在家庭环境中遇到的燃烧和非燃烧气溶胶来源的颗粒区域呼吸剂量。普通人群长期接受的总剂量远高于城市户外污染造成的剂量。在每次离子源操作结束时，这些剂量的75％至99％和27％至93％分别归因于超细颗粒，分别基于颗粒数量和表面积指标。取决于辐射源，在很短的时间内，曝光模式可能会非常强烈（最多8.0×10 ^9个 粒子s ^-1）并包含约10 nm模式的一小部分粒子。对于由电刷电动机操作的设备，此模式是主要模式，这是由于生成了铜纳米颗粒。由于铜离子与阿尔茨海默氏病之间的关联，这种颗粒可能会转移到大脑，并且与健康相关，因此值得特别关注，这是由多项研究提出的。
