Special Issue Information
Dear colleagues,
The influence of ultrafine particulate on human health has recently raised concerns, as airborne nanoparticles resulting both from nanotechnology processes and, also, from macroscopic industrial processes is increasing. In fact, nanotoxicological research is still in its infancy, and the issuing and implementation of standards for appropriate safety control systems may still take several years. Nonetheless, the advanced understanding of toxicological phenomena at the nanometer scale is largely dependent on technological innovations and scientific results stemming from enhanced R&D. The adverse health effects of inhaling fine aerosols have been recognized and various attempts have been made to minimize exposure, such as the issuing of specific regulations on emissions and objectives for air quality. While toxicological testing of nanoparticles entering through the skin or gastrointestinal tract is now starting to be tried, inhalation technology has been concerned with both naturally occurring and engineered nanometer sized materials. Some studies, however, had contradictory and controversial conclusions, and little or no standardization of experimental parameters. In particular, standard toxicology tests have been found to be unsuitable to explain toxicity of nanometer-sized particles, leading nanotoxicology laboratories to recommend the adoption of another type of metric that takes into account the materials’ active surface area and structure. Therefore, recent nanotoxicology studies are trying to reach reproducible results by determining the surface effects and other physical parameters of materials.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxics is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
