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.
