Over the past decade, there has been exponential growth in low-cost air pollution sensing technology. While low-cost sensors can provide a path towards more accessible air quality measurement, there are several guidelines that should be considered prior to deploying a low-cost sensor network. In this tutorial guide, we focus on low-cost aerosol sensors (in this case, PM2.5). The tutorial reviews k...

Low-cost sensors for particulate matter mass (PM) enable spatially dense, high temporal resolution measurements of air quality that traditional reference monitoring cannot. Low-cost PM sensors are especially beneficial in low and middle-income countries where few, if any, reference grade measurements exist and in areas where the concentration fields of air pollutants have significant spatial gradi...

Technical support document on the use of reference and non-reference methods, and on the quality assurance process to meet relevant data quality objectives for regulated air pollutants : final versionThis document provides technical details and support for the implementation of air quality monitoring under the Directive (EU) 2024/2881 of the European Parliament and of the Council of 23 October 202...

This page covers criteria air pollutants included in the U.S. National Ambient Air Quality Standards and provides guidance on setting and reviewing standards for each of these pollutants:Ground-Level OzoneParticle PollutionNitrogen DioxideSulfur DioxideCarbon MonoxideLead...

Community air quality monitoring consists of local efforts to measure and understand what is in the air a community breathes in. This type of monitoring is often conducted using air sensors or other instruments by community groups or members.The Community Air Monitoring Fundamentals Webinar Series consists of five sessions that cover:Fundamental information on air quality conceptsHow air quality a...

The European Topic Centre on Air Quality (ETC-AQ), under contract to the European Environment Agency (EEA) is required as part of its work programme to develop and maintain a European Air Quality Monitoring Network and a European Air Quality Information System in close collaboration with the European countries. The purpose is to obtain adequate background information for making air quality assessm...

The revised EU air quality directive sets new air quality standards for pollutants to be reached by 2030 which are more closely aligned with the WHO air quality guidelines. Those pollutants include, among others, particulate matter PM10 and PM2.5, nitrogen dioxide and sulphur dioxide, all known to cause respiratory problems. Member states may request that the 2030 deadline be postponed if specific...

To support national and global efforts to meet the goals of the Paris Agreement and keep the 1.5°C temperature limit within reach, the Climate and Clean Air Coalition urges countries to include non-CO₂ pollutants in their Nationally Determined Contributions (NDCs).The CCAC Guidance provides practical and strategic recommendations for experts and teams involved in preparing NDC 3.0 on how to set go...

Objectives: National ambient air quality standards (NAAQS) are critical tools for controlling air pollution and protecting public health. Authors designed this study to 1) gather the NAAQS for six classical air pollutants: PM2.5, PM10, O3, NO2, SO2, and CO in the Eastern Mediterranean Region (EMR) countries, 2) compare those with the updated World Health Organizations Air Quality Guidelines (WHO A...

The ASEAN Agreement on Transboundary Haze Pollution is a legally binding environmental agreement signed in 2002 by the member states of the Association of Southeast Asian Nations to reduce haze pollution in Southeast Asia....
