Workplace Measurements of Ultrafine Particles—A Literature Review
TLDR
Measurements of the UFP in work environments are, to date, too limited and reported too heterogeneous to allow us to draw general conclusions about workers' exposure, and showed that workers' Exposure to UFP may be significantly higher than their non-occupational exposure to background concentration alone.Abstract:
Workers are exposed to ultrafine particles (UFP) in a number of occupations. In order to summarize the current knowledge regarding occupational exposure to UFP (excluding engineered nanoparticles), we gathered information on UFP concentrations from published research articles. The aim of our study was to create a basis for future epidemiological studies that treat UFP as an exposure factor. The literature search found 72 publications regarding UFP measurements in work environments. These articles covered 314 measurement results and tabled concentrations. Mean concentrations were compared to typical urban UFP concentration level, which was considered non-occupational background concentration. Mean concentrations higher than the typical urban UFP concentration were reported in 240 workplace measurements. The results showed that workers' exposure to UFP may be significantly higher than their non-occupational exposure to background concentration alone. Mean concentrations of over 100 times the typical urban UFP concentration were reported in welding and metal industry. However, according to the results of the review, measurements of the UFP in work environments are, to date, too limited and reported too heterogeneous to allow us to draw general conclusions about workers' exposure. Harmonization of measurement strategies is essential if we are to generate more reliable and comparable data in the future.read more

The health effects of ultrafine particles
TL;DR: How ultrafine particles measuring less than 100 nanometres in diameter elicit greater inflammatory responses and stay in the lungs longer than larger particles is described, which can trigger heart disease, diabetes, cancer, neurological disorders and respiratory ailments, especially among children and people with long-term occupational exposure.

TL;DR: It is established that office workers are constantly exposed to nonprinter derived particle concentrations, with up to an order of magnitude difference in such exposure among offices, and it is proposed that such exposure be controlled along with exposure to printer derived particles.

TL;DR: A general exposure assessment model can be applicable for private, public, and occupational indoor exposure assessment, making it a valuable tool for public health professionals, product safety designers, industrial hygienists, building scientists, and environmental consultants working in the field of IAQ and health.
A review of commuter exposure to ultrafine particles and its health effects
TL;DR: In this paper, the authors identified 47 exposure studies performed across 6 transport modes: automobile, bicycle, bus, automobile, rail, walking and ferry, respectively, encompassing approximately 3000 individual trips where UFP concentrations were measured.

TL;DR: Nanoscale TiO2 (nTiO2) is manufactured in high volumes and is of potential concern in occupational health and here, workers exposure levels were measured while ceramic honeycombs were dip coated with liquid photoactive nanoparticle suspension and dried with an air blade to assess process specific emission rates.

Engines and nanoparticles: a review
TL;DR: In this article, a new HEI study showed that some low-emission diesel engines emit much higher concentrations of nanoparticles than older designs and other low-EMission designs, which has raised questions about whether nanoparticle (number based) emission standards should be imposed.

Pulmonary effects of inhaled ultrafine particles.
TL;DR: The hypothesis that ultrafine particles are causally involved in adverse responses seen in sensitive humans is based on several studies summarized in this brief review, and the studies performed so far support the ultrafine particle hypothesis.
