Physical processes are keys for the status of a lake. In this Special Issue, the emphasis is on dissolved oxygen and on exchange of gases, energy and momentum between atmosphere and further mixing and consumption within the water. The studies presented relate to ice-free as well as ice-covered lakes. Field measurements are combined with theoretical approaches.

This Special Issue consists of fourteen original scientific articles concerning different problems associated with the water quality of freshwater ecosystems in a temperate climate. Most of the articles deal with the relationship between water quality and the structure of ecosystem biocenoses. The conclusion of these articles confirms the fact that the deterioration of water quality has a direct impact on the quantitative and qualitative structure of biocenoses. This is accompanied by a decline in biodiversity and the disappearance of rare plant and animal species. They also draw attention to the particular importance of internal physical and chemical differentiation within the aquatic ecosystem, both in horizontal and vertical dimensions. The problem of ensuring proper ecological conditions and good quality of water in freshwater aquatic ecosystems is also raised, and various methods for the restoration of water bodies are presented. This Special Issue contributes to a better understanding of the causes of water quality deterioration, the mechanisms responsible for the functioning of ecosystems, including the decrease of biodiversity and the possibilities of improving their condition. Thus, it can be helpful for regaining the good ecological status of water bodies required by the Water Framework Directive.

Geophysical, environmental, and urban fluid flows (i.e., flows developing in oceans, seas, estuaries, rivers, aquifers, reservoirs, etc.) exhibit a wide range of reactive and transport processes. Therefore, identifying key phenomena, understanding their relative importance, and establishing causal relationships between them is no trivial task. Analysis of primitive variables (e.g., velocity components, pressure, temperature, concentration) is not always conducive to the most fruitful interpretations. Examining auxiliary variables introduced for diagnostic purposes is an option worth considering. In this respect, tracer and timescale methods are proving to be very effective. Such methods can help address questions such as, "where does a fluid-born dissolved or particulate substance come from and where will it go?" or, "how fast are the transport and reaction phenomena controlling the appearance and disappearance such substances?" These issues have been dealt with since the 19th century, essentially by means of ad hoc approaches. However, over the past three decades, methods resting on solid theoretical foundations have been developed, which permit the evaluation of tracer concentrations and diagnostic timescales (age, residence/exposure time, etc.) across space and time and using numerical models and field data. This book comprises research and review articles, introducing state-of-the-art diagnostic theories and their applications to domains ranging from shallow human-made reservoirs to lakes, river networks, marine domains, and subsurface flows

In recent decades, the environmental impact of organic pollutants, especially persistent and emerging organic pollutants, has attracted widespread attention, and related research has been rapidly developed. Organic pollutants represent a popular topic of research in the environmental field. Large amounts of organic pollutants, which are widely distributed in air, water, sediment, soil, and other environmental media, are created via industrial production and other human activities. A series of research projects have been carried out regarding the development of analytical methods for organic pollutants, the distribution of environmental media, environmental concentration, environmental fate, the exploration of new pollutants, and the non-target analysis of organic pollutants.
