Comprising 12 chapters, this book focuses on volatile methylsiloxanes (VMSs), the shorter-chained organosiloxanes, and reviews the main areas and environmental compartments where they have been found and studied. It opens with a detailed description of the structural and functional properties, toxic risks and possible transformations of VMSs in the environment and their main uses in various activities and products, as well as the identification of the main sources of emission. Further chapters examine the analytical strategies and protocols that have been used to address the quantification of VMSs, including the issue of possible cross-contaminations. The book also discusses the presence of VMSs in wastewater treatment plants (WWTPs) and in water bodies, their atmospheric fate and levels in biota, as well as occurrences of VMSs in remote areas of the world. It closes with a comprehensive conclusion and discussion on future directions for upcoming studies. This book is not intended as a finishing line, but rather as an important step towards improving our understanding of VMSs, to fuel new collaborations between research groups and/or with industry and lastly to convince more researchers to explore the mysteries of these ubiquitous, yet understudied, chemicals.

This book presents developments of novel techniques and applies them in order to understand the interactions between thermally driven mesoscale flows (sea and mountain breezes) and the turbulent exchange within the atmospheric boundary layer. These interactions are not accurately reproduced in the meteorological models currently employed for weather forecasting. Consequently, important variables such as air temperature and wind speed are misrepresented. Also, the concentrations of relevant greenhouse gases such as CO2 are considerably affected by these interactions. By applying a systematic algorithm based on objective criteria (presented here), the thesis explores complete observational databases spanning up to 10 years. Further, it presents statistically significant and robust results on the topic, which has only been studied in a handful of cases in the extant literature. Lastly, by applying the algorithm directly to the outputs of the meteorological model, the thesis helps readers understand the processes discussed and reveals the biases in such models.
