Nanosilver – Occupational exposure limits

Medycyna Pracy, 2015
Historically, nanosilver has been known as colloidal silver composed of particles with a size below 100 nm. Silver nanoparticles are used in many technologies, creating a wide range of products. Due to antibacterial properties nanosilver is used, among others, in medical devices (wound dressings), textiles (sport clothes, socks), plastics and building ...

A Human-Relevant 3D In Vitro Platform for an Effective and Rapid Simulation of Workplace Exposure to Nanoparticles: Silica Nanoparticles as Case Study

Nanomaterials, 2020
In this contribution, we show the suitability of a 3D airway model, when coupled with a nebulizer system, for simulating workplace exposure to nanoparticles. As a proof of concept, workplace exposure to silica nanoparticles was experimentally measured in

Simple fabrication of an electrospun polystyrene microfiber filter that meets N95 filtering facepiece respirator filtration and breathability standards

Journal of Applied Polymer Science, Volume 140, Issue 5, February 5, 2023., 2023
The COVID‐19 pandemic led to a backlog of filtration material for N95 Filtering Facepiece Respirators (FFRs). An alternative face mask filter material is presented, consisting of an unsupported, nonwoven layer of uncharged polystyrene microfibers. This microfiber material meets NIOSH N95 FFR filtration and breathability requirements, demonstrates ...

Environmental Contamination and Occupational Exposure of Algerian Hospital Workers

Frontiers in Public Health, 2020
Guidelines are in place to assure limited occupational exposure to cytostatic drugs. Even though this has led to a reduction in exposure, several studies reported quantifiable concentrations of these compounds in healthcare workers.

AI exposure predicts unemployment risk [PDF]

arXiv, 2023
Is artificial intelligence (AI) disrupting jobs and creating unemployment? Despite many attempts to quantify occupations' exposure to AI, inconsistent validation obfuscates the relative benefits of each approach. A lack of disaggregated labor outcome data, including unemployment data, further exacerbates the issue.

Residual cognitive deficits 50 years after lead poisoning during childhood [PDF]

, 1993
The long term neurobehavioural consequences of childhood lead poisoning are not known. In this study adult subjects with a documented history of lead poisoning before age 4 and matched controls were examined with an abbreviated battery of ...

Wage arbitrage through skilled emigration: Evidence from the Pacific Islands

Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 430-446, September 2022., 2022
Abstract Skilled workers in poor countries earn wages a fraction of that of their counterparts in rich nations. Here, we estimate the opportunities for wage arbitrage from emigration of workers from the Pacific Islands into Australia and New Zealand. Our calculations, based on wages earned by graduate accountants, computer science graduates and cooks ...

Harnessing the potential of online marketplaces in the Philippines: Insights from the National Information and Communications Technology Household Survey

Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 288-316, September 2022., 2022
Abstract Using the Philippinesʼ first nationally representative survey designed to characterise digital commercial and non‐commercial engagements, including the use of information and communications technology (ICT), the digital economy, and technology‐enabled activities, we investigate the presence of gendered disparities in online marketplaces.
