Summary
The course is comprehensively focused on the use of nanomaterials for environmental protection, but also on the presence of nanomaterials as undesirable components in the environment. Attention is paid to selected applications of nanomaterials for environmental analysis, methods of air, water and soil purification using nanomaterials. Following this, the issue of release, transformation and possible impacts of the presence of nanomaterials in individual components of the environment is discussed. Special attention is paid to the key parameters of nanomaterials, which are crucial for the possible negative effects of their presence in the environment, also in relation to the exposure of living organisms to these materials. The issue of contamination of individual components of the environment with nanomaterials and possible impacts resulting from it, including the final phase of the life cycle of nanomaterials, when they become waste materials, are also discussed. Due to the exposure of living organisms to these materials in the environment, attention is paid to the possible effects of nanomaterials on living organisms at the molecular, cellular and organ levels for organisms of different trophic levels. With regard to the issue of testing nanomaterials, the content of the course also includes the issue of ethical aspects and, in the final stage, the legislative framework for the use of nanomaterials.
