Накратко на български
Изкуствените наноматериали се променят физически и химически, докато преминават през пречиствателни станции за отпадни води. Разбирането на тези процеси помага да се оцени как частиците влияят върху околната среда и токсичността им.

Effect of water and wastewater treatment on the properties of engineered nanomaterials (ENMs) in context of their fate, toxicity and interaction with other contaminants
Behavior of engineered nanomaterials (ENMs) in the environment differs from the pathways observed for larger particles. Due to the special properties of ENMs and a wide range of their applications, attempts are made to estimate the fate of ENMs in the environment and transformations during their use and storage . The release of ENMs may occur during the use of materials containing nanoparticles, their processing or disposal and storage. It is assumed that the major part of ENMs gets into the environment with wastewater. During their transport and release into the environment, ENMs may undergo different transformations. As released ENMs will firstly get into wastewaters, one can expect that they will be subject to various processes of transformation there. Transformations of the material (coated and nanohybrids) can therefore affect the core material, the capping agent, or both. We currently lack sufficient knowledge of the types, rates, and extent of transformations expected for ENMs during water and wastewater treatment. The proposed study is the first which investigates how various water and wastewater treatment methods will influence the physicochemical and ecotoxicological properties of ENMs (Fig. 1). Recognition of this problem has an extremely important aspect of cognition in a situation of increasing ENMs production. Acquired new knowledge on this topic lead to a better understanding of the mechanisms and processes in the environment. The research will contribute to a broad base of knowledge that will be the basis for solving of known or expected future problems related to the use of ENMs. Innovative aspects of the work were: (1) Investigation of the effects of different water and wastewater treatment process on ENMs properties (WP1); (2) Determination of ENMs changes during water/wastewater treatment and how these changes affect ENMs fate (aggregation, mobility, bioaccumulation) in the environment (WP2); (3) Determination of how change in ENMs properties may result in a change in the strength of interactions with other contaminants, thus affecting their bioavailability and toxicity (WP3); (4) Evaluation of ENMs toxicity to different organisms in connection of changes ENMs properties (WP4).

Цел на проекта
The primary goal of this study is to use the state-of-the-art methods to study the changes of engineered nanomaterials (ENMs) during water and wastewater treatment and to evaluate how these changes will affect ENMs fate, toxicity and interaction with other contaminants. It is assumed that the major part of ENMs gets into the environment with wastewater. It is interesting though to study how different conditions of water and wastewater treatment will affect ENMs properties. It is very important because of the changes in the physicochemical properties of ENMs caused by these processes may affect the mobility, toxicity and bioaccumulation of ENMs. Moreover, interaction between ENMs and other contaminants may affect their fate in the environment. These results may completely change our approach related to environmental risks associated with ENMs. In addition, the results may open a new area of research focused on realistic scenario. The achievement of these goals requires an inter- and multidisciplinary approach including environmental nanotechnology and chemistry, ecotoxicology, physics, material chemistry and engineering. These goals will be achieved through the implementation of research in one of the most advanced environmental nanotechnology lab in the world. During the outgoing phase I will be trained in new and powerful research techniques from laboratory experiments, physical and chemical analysis and field mesocosm experiment. During the return phase both groups will establish a collaboration, share theoretical and experimental expertise, and possibly initiate a long-term student exchange program. Beside of resolving very important environmental scientific issue, this fellowship will give me the opportunity to work with experts, will create a network of international collaborators, and will co-lead a 3-year long project with increased responsibilities in its conception, design, implementation, administration, and dissemination.
