The new particle formation due to the use of cleaning products containing volatile organic compounds (VOCs) in indoor environments is well documented in the scientific literature. Indeed, the physical‐chemical process occurring in particle nucleation due to VOC‐ozone reactions was deepened as well as the effect of the main influencing parameters (ie, temperature, ozone). Nonetheless, proper quantification of the emission under actual meteo‐climatic conditions and ozone concentrations is not available. To this end, in the present paper the emission factors of newly generated ultrafine particles due to the use of different floor cleaning products under actual temperature and relative humidity conditions and ozone concentrations typical of the summer periods were evaluated. Tests in a chamber and in an actual indoor environment were performed measuring continuously particle number concentrations and size distributions during cleaning activities. The tests revealed that a significant particle emission in the nucleation mode was present for half of the products under investigation with emission factors up to 1.1 × 10¹¹ part./m² (8.8 × 10¹⁰ part./mL_product), then leading to an overall particle emission comparable to other well‐known indoor sources when cleaning wide surfaces.

地板清洁产品的超细颗粒排放。

由于在室内环境中使用含有挥发性有机化合物 (VOC) 的清洁产品而导致的新颗粒形成在科学文献中有详细记载。事实上，由于VOC-臭氧反应导致粒子成核的物理化学过程以及主要影响参数（即温度、臭氧）的影响都加深了。尽管如此，在实际的气象气候条件和臭氧浓度下，无法对排放进行适当的量化。为此，在本论文中，评估了在实际温度和相对湿度条件下以及夏季典型的臭氧浓度下使用不同地板清洁产品而产生的新产生的超细颗粒物的排放因子。在室内和实际室内环境中进行了测试，在清洁活动期间连续测量颗粒数量浓度和尺寸分布。测试表明，在排放因子高达 1.1 × 10¹¹ part./m ²（8.8 × 10 ¹⁰ part./mL_产品），然后在清洁宽表面时导致与其他知名室内源相当的总体颗粒排放。
