“…Product B produced fewer particles compared to A. The variation in particle emissions among the two products may be due to differences in the spray nozzles ( Nuyttens et al, 2007 ) and the composition of the disinfectant solutions ( Kim et al, 2020 ). The observed particles are likely disinfectant droplets formed by the propellant spray process ( Bekker et al, 2014 , Hagendorfer et al, 2010 ).…”

“…In cases where the active product is in solution, the particle is formed after the solvent has evaporated. Kim et al (2020) showed that propellant-type products generated more particles than hand generated pressure. They found most of the particles were in sizes < 100 nm although some products produced an aerosol with a supermicron mode.…”

This chapter provides an overview of the section on Indoor Air Particles. This section focuses on the physical processes that affect particle concentrations and some major sources. Penetration of particles from the ambient aerosol into the indoor environment is an important source of indoor particles. The particles depending on their size can then deposit and can be resuspended. Semi-volatile species partition into particles and the gaseous phase depending on factors such as vapor pressure at typical indoor temperatures and solubility into organic phases. The dynamics of these processes are presented in separate chapters that are

Spray applications enable a uniform distribution of substances on surfaces in a highly efficient manner, and thus can be found at workplaces as well as in consumer environments. A systematic literature review on modelling exposure by spraying activities has been conducted and status and further needs have been discussed with experts at a symposium. This review summarizes the current knowledge about models and their level of conservatism and accuracy. We found that extraction of relevant information on model performance for spraying from published studies and interpretation of model accuracy proved to be challenging, as the studies often accounted for only a small part of potential spray applications. To achieve a better quality of exposure estimates in the future, more systematic evaluation of models is beneficial, taking into account a representative variety of spray equipment and application patterns. Model predictions could be improved by more accurate consideration of variation in spray equipment. Inter-model harmonization with regard to spray input parameters and appropriate grouping of spray exposure situations is recommended. From a user perspective, a platform or database with information on different spraying equipment and techniques and agreed standard parameters for specific spraying scenarios from different regulations may be useful.
