Camphene and 3-carene are key atmospheric monoterpenes used in cosmetics, fragrances, and food flavouring. In order to assess their impacts on human health and the environment it is essential to have a thorough understanding of the degradation mechanisms involved in their reactivity. The present study aimed to investigate the OH radicals initiated atmospheric degradation of camphene and 3-carene under simulated NOx-free conditions. The experiments were conducted using facilities provided by the 760 L Environmental...

Given the ubiquity of limonene in cleaning and cosmetic products, investigating its gasphase oxidation products from reactions with OH radicals and ozone has become important for human health. The present study investigates limonene gas-phase reaction with OH radicals under controlled NOx or NOx-free conditions using facilities from the 760 L Environmental Simulation Chamber made of Quartz (ESC-Q-UAIC) together with state-of-the-art instruments such as proton-transfer-reaction time-of-flight mass spectrometer (PTR...

Solid-state dissolution by sintering in the presence of Na2O2, a strong oxidizing agent, isreported in the present study as a preparatory procedure prior analysis by ICP-MS. Theadequacy of the combined procedure for the purpose of identification of potentialsecondary sources for REEs from difficult matrixes like, for example, mining wasteswas investigated. The method was applied to Certified Reference Materials (CRMs)with silicate-rich complex matrices, namely rhyolite, and granite. From each materialtwo sample we...
