Short summary
Oxymethylene ethers are a class of sustainable compounds that could be used to replace harmful organic solvents in a range of applications. In this work, we use lab-based experiments to identify the main breakdown routes of these compounds in the atmosphere. We have determined that they likely contribute less to air pollution than the compounds that they replace.

Solvents represent an important source of pollution from the chemical industry. New "green" solvents aim to replace toxic solvents with new molecules made from renewable sources and designed to be less harmful. Whilst these new molecules are selected according to toxicity and other characteristics, no consideration has yet been included on air quality. Studying the solvent breakdown in air, we found that TMO has a lower impact on air quality than traditional solvents with similar properties.

Short summary
OH and HO2 are key reactive intermediates in the Earth's atmosphere. Accurate measurements in either the field or simulation chambers provide a good test for chemical mechanisms. Fluorescence techniques have the appropriate sensitivity for detection but require calibration. This paper compares different methods of calibration and specifically how calibration factors vary across a temperature range relevant to atmospheric and chamber determinations.

Short summary
This work explores the kinetics and reactivity of epoxides towards the OH radical using two different simulation chambers. Estimation of the rate coefficients has also been made using different structure–activity relationship (SAR) approaches. The results indicate a direct influence of the structural and geometric properties of the epoxides not considered in SAR estimations, influencing the reactivity of these compounds. The outcomes of this work are in very good agreement with previous studies.

Short summary
Within this work we determined the rate coefficients and products of the reaction of unsaturated ketones with OH radicals in an effort to complete the gaps in the knowledge needed for modelling chemistry in the atmosphere. Both substances are potentially emitted by biomass burning, industrial activities or formed in the troposphere by oxidation of terpenes. As products we identified aldehydes and ketones which in turn are known to be responsible for the transportation of NOx species.

Short summary
Gas-phase reaction rate coefficients of OH radicals with four nitrocatechols have been investigated for the first time by using ESC-Q-UAIC chamber facilities. The reactivity of all investigated nitrocatechols is influenced by the formation of the intramolecular H-bonds that are connected to the deactivating electromeric effect of the NO2 group. For the 3-nitrocatechol compounds, the electromeric effect of the
freeOH group is diminished by the deactivating E-effect of the NO2 group.
