Special Issue Information

Dear Colleagues,

Toner is a particulate matter 5-10 μm in diameter that is used in copiers and laser printers to form images and text printed on paper. The toner itself is a micron-sized powder, not a nano-sized particle, but industrial nanomaterials are used as its constituents. Industrial nanomaterials include colorants such as carbon black (dispersed in the resin, which is the main component of toner), nano titanium dioxide, and nano amorphous silica as an external additive.

Cases of siderocylicosis due to toner exposure were first reported in 1994, and since then case reports of sarcoidosis, allergic rhinitis, asthma, etc., associated with toner exposure have been published. These reports raise concerns about the health effects associated with toner exposure and the use of copiers and printers. Recent studies show that office equipment such as printers and copiers emit particulate matter (PM) when used, which can increase indoor air pollution.. The health effects of toner exposure and the health effects of PM released from office equipment should be assessed separately.

Still, there is insufficient scientific evidence regarding the long-term health effects of toner exposure.

This Special Issue aims to gather high-quality and innovative manuscripts concerning environmental research findings, such as the content of toner particles in the air, as well as research concerning the health effects of various toner particles.

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. Atmosphere 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 2400 CHF (Swiss Francs).

A cohort study spanning ten years was conducted to assess the health effects on toner manufacturing workers. A survey consisting of questions investigating subjective respiratory symptoms, current medical history, disease occurrence, dust exposure concentrations at the workplace, respiratory function tests, biochemical and immunological items in blood and urine, and a chest radiograph or chest computed tomography survey was conducted. The results of these surveys have been published in academic journals, and none of the surveys showed any findings suggesting significant health problems in the toner-worker group compared to the non-toner-worker group. The results suggest that the health risks associated with toner handling are not high when the work environment at the toner handling site is well controlled. Full article
