Background Particulate matter (PM) is not a single pollutant, but a mixture of particles of different sizes, compositions, and origins. The size of these particles determines how long they remain suspended in the air and how deeply they penetrate the human respiratory...
Urban traffic emissions monitoring makes it possible to measure pollutants such as NO2, PM2.5, CO, and O3 in real time in order to assess the impact of transportation on air quality. These sensor networks support the management of low-emission zones, the detection of...
LDAR (Leak Detection and Repair) systems are advanced technical programs designed to detect industrial fugitive emissions. Their purpose is to identify and repair invisible losses of gases or vapours in critical industries such as the chemical, petrochemical and...
Ultrafine particles (UFPs) are atmospheric pollutants that expose the challenge of measuring the infinitely small. With a diameter smaller than 100 nanometres (PM0.1), their danger does not stem from their weight (almost negligible) but from their numerical...
The countryside has always been the economic and social heart of rural areas, but it also hides a less visible reality: an atmosphere that changes in rhythm with tractors, barns, and fertilisers. For years, agriculture and livestock farming have quietly sustained...
Wastewater treatment plants (WWTPs) are essential infrastructures as they play a crucial role in completing the urban water cycle. By ensuring proper treatment and water reuse, they are key to protecting water resources while also directly influencing air quality....
Despite their reputation for pristine environments, islands around the world — from Hawai‘i and the Caribbean to those in the South Pacific and the Mediterranean — face growing challenges concerning air quality. A global study by IQAir highlights that only a handful...
Addressing a natural process such as environmental corrosion or material degradation, in which materials in contact with the environment undergo a progressive deterioration over time, means facing a public safety issue. This natural situation worsens when atmospheric...
Considering that a significant share of industrial and domestic organic waste can be used as feedstock for the production of biogas and biomethane opens the door to one of the most promising and necessary energy revolutions of the 21st century. In 2025, Europe is...
