Nanomaterials and Environment

The subject is focused on the complex issue of nanomaterials presence in the environment due to intentional applications or as by-products of various anthropogenic activities. Further, the issue of release, transformation and potential impact of occurence of nanomaterials in single environmental compartments is presented. Key parameters of nanomaterials having decisive impact on potential adverse effects related to occurence of nanomaterials in the environment also with respect to exposure of living organisms to these materials are emphasized. Moreover, nanomaterials as contaminants of single environmental compartments (i.e. air, water and soil) and resulting potential adverse effects are discussed together with the issue of the end phase of nanomaterials life-cycle when there are becoming wastes. Due to the exposure of living systems to nanomaterials present in the environment also the topic of nanomaterials efects on molecular, celullar and organ levels for organisms from single trophic levels is discussed. The topic of ethical aspects and legiclative framework are also included with respect to the nanomaterials assessment and applications.
