Short summary
Short summary
Ethyl butyrate and its methylated derivatives are volatile and commonly used aroma compounds, yet their gas-phase chemistry and air quality impact remain poorly characterised. In this work, we investigated the reactivity of these compounds experimentally. We determined temperature-dependent rate coefficients for their reaction with the main atmospheric oxidant, OH, and found that this was the dominant tropospheric loss process. In contrast, direct photolysis is negligible under most conditions.

Short summary
Exposure to air pollution is one of the greatest risks to human health, and it is indoors, where we spend upwards of 90 % of our time, that our exposure is greatest. The INdoor CHEMical model in Python (INCHEM-Py) is a new, community-led box model that tracks the evolution and fate of atmospheric chemical pollutants indoors. We have shown the processes simulated by INCHEM-Py, its ability to model experimental data and how it may be used to develop further understanding of indoor air chemistry.
Exposure to air pollution is one of the greatest risks to human health, and it is indoors, where...
