This paper presents the findings from a collaborative interlaboratory comparison exercise designed to assess oxidative potential (OP) measurements conducted by 20 laboratories worldwide. This study represents an innovative effort as the first exercise specifically aimed at harmonising this type of OP assay, setting a new benchmark in the field. Over the last decade, there has been a noticeable inc...

Volatile and intermediate-volatility non-methane organic gases (NMOGs) released from biomass burning were measured during laboratory-simulated wildfires by protontransfer-reaction time-of-flight mass spectrometry (PTRToF). Authors identified NMOG contributors to more than 150 PTR ion masses using gas chromatography (GC) preseparation with electron ionization, H3O + chemical ionization, and NO+ che...

Over the last 2 decades, the importance of emissions source types of atmospheric pollutants in urban areas has undergone significant change. In particular, there has been a considerable reduction in emissions associated with road vehicles. Understanding the role played by different source sectors is important if effective air pollution control is to be achieved. Current atmospheric measurements ar...

Authors have developed a field-deployable gas chromatograph (GC) with thermal desorption preconcentration (TDPC), which is demonstrated here with automatic detector switching between two high-resolution time-of-flight mass spectrometers (TOF-MSs) for in situ measurements of volatile organic compounds (VOCs). This system provides many analytical advances, including acquisition of fast time–response...

This document provides guidance on the list of volatile organic compounds (VOCs) state and local monitoring agencies should attempt to measure at their Photochemical Assessment Monitoring Stations (PAMS) monitoring sites.This is an update to the list of original PAMS target compounds listed in the order they eluted on the original PAMS autoGC systems. Elution sequence may be different on current a...

Carbonaceous aerosol particles are associated with large uncertainties in their climate impacts because of incomplete knowledge of their optical properties and emission magnitudes. Biomass-burning sources significantly contribute to carbonaceous aerosol emissions in India, with crop residue burning being crucial during post-harvest months. Here, for the first time, authors study the chemical and o...

Since the end of 2019, Airparif has been monitoring the temporal variations of Ultrafine Particles (UFP) levels in central Paris (Les Halles garden) and is conducting a project to study the spatial variability of their levels across the Paris Region (Ile-de-France) in a variety of environments (urban and rural backgrounds, near road traffic and airport platforms). These solid airborne particles ha...

This service from UK Gov allows users to view and download air pollution data from monitoring networks across the UK. Users can search data by town or postcode, or create a custom dataset....

In 2016, the ‘FAIR Guiding Principles for scientific data management and stewardship’ were published in Scientific Data. The authors intended to provide guidelines to improve the Findability, Accessibility, Interoperability, and Reusability of digital assets. The principles emphasise machine actionability (i.e., the capacity of computational systems to find, access, interoperate, and reuse data wi...

This Standard Reference Material (SRM) is intended primarily for use in the evaluation and calibration of analytical methods for the determination of trace level organic constituents on atmospheric particulate matter or on materials with a similar matrix. This material is atmospheric particulate matter collected in an urban location.Certified values of selected organic constituents, polycyclic aro...
