ScienceDirect.com | This study introduces two new CO₂-based surrogates, per-person dilution (pCO₂) and room dilution (rCO₂), to more accurately interpret airborne infection risk by accounting for both emission and removal dynamics of infectious aerosols in indoor environments.

SatNews | Europe’s new Copernicus Sentinel-4 mission has captured its first air quality images from geostationary orbit, providing hourly, high-resolution data on pollutants like nitrogen dioxide, ozone, and sulphur dioxide to enhance pollution monitoring and forecasting across the continent.

Nature | The UK’s air quality management system limits genuine public participation by involving citizens only after pollution thresholds are breached, highlighting the need for structural reform that values local knowledge and embeds community input throughout decision-making processes.

Santa Barbara County Air Pollution Control District | California has expanded the Protecting Blue Whales and Blue Skies program statewide, reducing ship speeds to prevent whale strikes and cut emissions by 27%, equivalent to removing 900,000 cars from the road annually.

ResearchGate | A nationwide French study found that prenatal exposure to fine particulate matter (PM2.5), black carbon, and nitrogen dioxide increases the risk of childhood acute leukemia, particularly acute lymphoblastic leukemia, supporting a link between early-life air pollution and cancer risk.

Human Rights Watch | Human Rights Watch reported to the UN that weak regulation and enforcement of air quality standards in countries such as the U.S., Türkiye, Bosnia and Herzegovina, and the UAE allow fossil fuel operations to emit dangerous pollution, disproportionately harming marginalized communities and violating the right to health.

ESS Open Archive | Satellite data from 2019–2024 show that 79% of 1,400 cities worldwide experienced significant declines in tropospheric NO₂, led by major reductions in China and Europe, while increases were observed in parts of the Middle East and South Asia, notably Tehran and Cairo.

WREX | In recent years, wildfire smoke from Canada’s prairies has increasingly degraded surface air quality in northern Illinois and southern Wisconsin, marking a shift from previously higher-altitude California smoke and underscoring changing environmental impacts on regional air conditions.

BBC | Delhi’s air quality plunged to its worst post-Diwali levels in four years as a mix of firecracker emissions, vehicle pollution, and renewed stubble burning across Punjab, Haryana, and Uttar Pradesh combined with stagnant winter air to trap toxic haze over the city.

Southern Environmental Law Center | A Harvard School of Public Health report commissioned by the Southern Environmental Law Center found that Santee Cooper and Dominion Energy’s proposed Canadys methane gas plant could expose over two million people to harmful PM2.5 pollution, disproportionately affecting Black and low-income communities and costing up to $36 million annually in health-related impacts by 2040.
