Abstract
There have been many reports on the adverse impacts of exposures to particulate matter in the air but relatively few of these have been related to exposures to ultrafine particles (UFP) in the indoor environment. To investigate exposures to (UFP) in domestic environments, and the association with childhood respiratory symptoms in Zongshan, China a modified Thoracic Society questionnaire was completed by 359 households with children. Air quality monitoring took place in 37 households using a P-Trak instrument to determine concentration of UFPs in rooms. The mean number of UFP was 4.1 × 10(4) cm(-3). A range of factors was found to be associated with UFP concentration and self-reported childhood respiratory symptoms. In conclusion, the evidence suggests that behavioural and environmental factors contribute to increased UFP concentrations indoors although there was no statistically signification correlation between indoor ultrafine particle concentration and any reported repeated episodes of respiratory symptoms.
国内環境とZongshanの小児期呼吸器症状との関連で暴露量を調査する（UFP）、改訂胸部の協会アンケートがそうであった中国は、小児と359の家庭によって完了した。
空気質監視は、部屋でUFPsの濃度を測定するためにP-Trak器具を使用している37の家庭で起こった。
UFPの平均個数は、4.1×10(4)cm（-3）であった。
因子の範囲が、UFP濃度と自己申告性小児期呼吸器症状と関係しているとわかった。
結論として、証拠は、屋内の超微細の粒子濃度と少しの既報告の反復呼吸器症状症状の発現間の意義相関も少しも統計学的になかったにもかかわらず、その行動に関するおよび環境要因が屋内の増加したUFP濃度に関与することを示唆する。
