Non-Methane Volatile Organic Compounds (NMVOCs) from domestic aerosol sprays are emerging pollutants and have substantial negative effects on human health and the environment. This study, for the first time, carried out quantification of the NMVOC emissions from off-the-shelf domestic aerosol sprays, at “source” in the UK. These aerosol sprays contain harmful organic compounds as propellants and products. The results showed that the cosmetic category (i.e. body sprays) have higher concentrations of NMVOCs with 93.7 wt% per can compared to households (i.e. air fresheners) with 62 wt%. Also, water-based products showed less NMVOCs in all analyses compared to solvent-based formulations. Direct replacement of Liquefied Petroleum Gas (LPG) propellants from conventional products with ‘clean air’ (i.e. nitrogen) showed the potential emission reduction of 50%. Hair spray products, however, have the highest ozone forming potential with about 105.1 g of Ozone per litre of the product compared to other domestic aerosol sprays. The level of global warming contribution of the selected aerosol sprays in the UK was measured to be 129.8 ktCO2e in 2018 and globally, this can be projected to be 3154.6 ktCO2e in 2020. Furthermore, NMVOC emissions contribution from the domestic aerosol sprays in the UK was measured as 61.2 kt in 2018 based on annual consumption of 520 million cans. Globally this can equate to 1437.6 kt based on the projected usage of 17.5 billion cans. Therefore, it is vital to expedite replacing LPG propellant with nitrogen in a drive for a ‘near-zero’ emission in aerosol industry. The results presented in this study can also be used to steer policy makers to the potentially brewing danger from an otherwise passive emission source.

在“来源”处测量和分析家用主要气雾剂产生的非甲烷VOC(NMVOC)排放量
来自家用气雾剂的非甲烷挥发性有机化合物(NMVOCs)是新兴的污染物,对人类健康和环境具有重大的负面影响。这项研究首次在英国“源头”对来自现成的家用气雾剂的NMVOC排放进行了量化。这些喷雾剂含有有害的有机化合物作为推进剂和产品。结果表明,与具有62 wt%的家庭(即空气清新剂)相比,化妆品类别(即身体喷雾剂)的NMVOC浓度更高,每罐为93.7 wt%。此外,与溶剂型配方相比,水基产品在所有分析中均显示出较少的NMVOC。用“清洁空气”直接将常规产品中的液化石油气(LPG)推进剂替代(即 氮)的排放量降低了50%。但是,与其他家用喷雾剂相比,发胶产品具有最高的臭氧形成潜能,每升产品中的臭氧含量约为105.1克。在英国,选定的气溶胶喷雾剂对全球变暖的贡献水平经测量为129.8 ktCO2和在2018年和全球E,这是可以预计为3154.6 ktCO 2 E在2020年。此外,在英国国内喷雾剂NMVOC排放贡献是基于520万罐年消费量测量61.2克拉在2018年。在全球范围内,根据预计的175亿罐使用量,这相当于1437.6 kt。因此,至关重要的是尽快用氮气替代LPG推进剂,以推动气雾剂行业的“近零排放”。这项研究中提出的结果还可以用于引导决策者防范其他被动排放源带来的潜在危险。
