Spectroscopy: The Next Step for Low-Cost Particulate Matter Sensors
The landscape of ambient air quality monitoring is evolving, driven by the increasing availability of low-cost sensors.While current low-cost particulate matter (PM) sensors, which rely on light scattering, provide valuable data on particle size and number, they lack the ability to determine a particle's composition. This limitation is a significant hurdle in understanding the true nature and origin of air pollution.

Elemental Carbon (EC) vs. Black Carbon (BC): A Distinction in Measurement and Terminology
The terms Elemental Carbon (EC) and Black Carbon (BC) are both used to describe the product of incomplete combustion of fossil fuels, biomass, and biofuels, which is a significant component of aerosols (airborne particulate matter). While often used interchangeably in general discussion, they represent distinct concepts primarily tied to their respective measurement methodologies. Understanding this difference is crucial in air quality monitoring, climate science, and health studies.

The EU’s New EPBD: Why Indoor Air Quality Needs a Unified Standard
The recently updated Energy Performance of Buildings Directive (EPBD) is a pivotal legislative framework aimed at improving the energy efficiency of buildings across the European Union. While its primary focus remains on energy savings and decarbonization, the revised EPBD now formally recognizes the crucial link between energy performance and Indoor Environmental Quality (IEQ). This update requires member states to address IEQ in their national legislation, ensuring that energy-efficient buildings also support the health, comfort, and well-being of their occupants.

The Unseen Air Inside Classrooms
In the modern classroom, the focus is often on technology, curriculum, and engagement. However, a critical element that directly impacts student health and learning often goes overlooked: the air they breathe. In many schools, especially older buildings, ventilation systems are inadequate or non-existent. This can lead to a buildup of pollutants and, most critically, an increased risk of airborne infections.
