Air Pollution

Chronic Diseases and Injuries in Canada, 2010
Toxic air pollutants are continuously released into the air supply. Various pollutants come from chemical facilities and small businesses, such as automobile service stations and dry cleaning establishments. Others, such as nitrogen oxides, carbon monoxide and other volatile organic chemicals, arise primarily from the incomplete combustion of fossil ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Biochemical Changes among Medical Laboratories Staff Occupationally Exposed to Formaldehyde Vapors

Journal of High Institute of Public Health, 2010
Background: Increased levels of tumour markers: carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC -Ag), Alpha feto protein (AFP), and neuron-specific enolase (NSE) may indicate the onset of the carcinogenic process.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Seasonal Variations in PM2.5-induced Oxidative Stress and Up-regulation of Pro-inflammatory Mediators

Aerosol and Air Quality Research, 2020
Inhaling particulate matter with an aerodynamic diameter of ≤ 2.5 µm (PM2.5) has been demonstrated to induce season-dependent adverse health effects. As inflammation and oxidative stress play a critical role in PM2.5-induced health effects, this study ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

The Swiss National Air Pollution Monitoring Network (NABEL) – Bridging Science and Environmental Policy

CHIMIA
Awareness of atmospheric air quality in Switzerland became a concern in the 1960s, as a result of which the Swiss National Air Pollution Monitoring Network (Nationales Beobachtungsnetz für Luftfremdstoffe - NABEL) was created in the 1970s.
