“…Carbon nanotubes (CNTs) consist exclusively of carbon atoms arranged in a series of condensed benzene rings rolled up into a tubular structure [139]. The toxicity of carbonbased nanomaterials depends on several properties, such as structure, length, surface area, surface charge, aggregation, oxidation, functional groups, manufacturing methods, morphology, concentration, and dosage [133,135,[147][148][149][150][151].…”

Many industrial processes, several natural processes involving non-living matter, and all the processes occurring within living organisms take place in solution. This means that the molecules playing active roles in the processes are present within another medium, called solvent. The solute molecules are surrounded by solvent molecules and interact with them. Understanding the nature and strength of these interactions, and the way in which they modify the properties of the solute molecules, is important for a better understanding of the chemical processes occurring in solution, including possible roles of the solvent in those processes. Computational studies can provide a wealth of information on solute–solvent interactions and their effects. Two major models have been developed to this purpose: a model viewing the solvent as a polarisable continuum surrounding the solute molecule, and a model considering a certain number of explicit solvent molecules around a solute molecule. Each of them has its advantages and challenges, and one selects the model that is more suitable for the type of information desired for the specific system under consideration. These studies are important in many areas of chemistry research, from the investigation of the processes occurring within a living organism to drug design and to the design of environmentally benign solvents meant to replace less benign ones in the chemical industry, as envisaged by the green chemistry principles. The paper presents a quick overview of the modelling approaches and an overview of concrete studies, with reference to selected crucial investigation themes.

“…Finally, the impact of residual transition metals that are included as catalysts in the engineered CNTs and CNFs, on the toxicological manifestations is important and should be studied [46]. Both the amount and quality of these residual impurities play a key role in the toxicity of carbon nanomaterials [78][79]. Moreover, the contaminants present in the carbonaceous nanomaterials may be also active in biological responses.…”

Nowadays, nanotechnology is applied to an increasingly number of industries due to the unique properties of nanomaterials. Carbon nanotubes and carbon nanofibers are some of the most appealing nanomaterials that are commonly employed in electronics, photovoltaic, catalysis, environmental engineering, space engineering, and last but not least in medicine and pharmacy. However, the issue of handling such materials is not yet fully investigated. Without the essential and proper legislations and regulations, widespread use of nanotechnologies in many sectors of society may well be slowed down and could even come to a complete standstill. Thus, it is necessary to develop innovative methods for risk management. The exposure assessment of carbon based nanomaterials presents several challenges. It is easily understood that nanosafety and risk assessment are upon modern research fields. Moreover, it seems critically important to take into perspective the whole life cycle for carbon nanotubes and carbon nanofibers for the risk management. The purpose of this review is to present the current state of knowledge related to the risks of carbon nanotubes and nanofibers as well as to display the current actions in European Union regarding this issue.
