Nanotoxicology, stemming from concerns about the toxicity of ultrafine particles in the environment, is an expanding field within toxicology. It investigates the toxicity of nanomaterials derived from various sources, including manufacturing and combustion processes, as well as natural occurrences. Certain cell subpopulations exhibit varying degrees of susceptibility to nanoparticles, often influenced by the cell cycle. Research in nanotoxicology is dedicated to understanding the potential harmful effects of nanoparticles and nanopharmaceuticals on both individuals and the environment. Efforts are underway to enhance data presentation quality, especially in test item characterization, within relevant scientific journals.
