Identification of organic pollutants in city atmospheres

open access: yesClean Air Journal, 1973
A suitable gas chromatophic analytical technique is described for the characterization of organic components in air samples from traffic dense areas. The method employs a chromosorb 102 cold trap to collect and concetrate samples and a 30 metre SCOT DC ...

Air Pollution and the Risk and Progression of Multiple Sclerosis: A Systematic Review and Meta‐Analysis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose Air pollution has been linked to several neurological conditions, including stroke and neurodegenerative diseases. Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. Methods PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Biochemical Changes among Medical Laboratories Staff Occupationally Exposed to Formaldehyde Vapors

open access: yesJournal 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.

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

open access: yesAdvanced Engineering Materials, EarlyView.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

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

open access: yesAerosol 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 ...

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

open access: yesAdvanced Engineering Materials, EarlyView.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...

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

open access: yesCHIMIA
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.

Potential role of polycyclic aromatic hydrocarbons in air pollution-induced non-malignant respiratory diseases

open access: yesRespiratory Research, 2020
Epidemiological studies have found strong associations between air pollution and respiratory effects including development and/or exacerbation of asthma and chronic obstructive pulmonary disease (COPD) as well as increased occurrence of respiratory ...
