Europe Faces 146,500 Premature Deaths from Air Pollution as Scientists Engineer Bacteria to Clean Explosive Residues

A study by ISGlobal and the Barcelona Supercomputing Center estimates that combined atmospheric pollutants cause at least 146,500 premature deaths each year across 31 European countries. Fine particulate matter (PM₂.₅) accounts for over 79,000 deaths, while nitrogen dioxide and ozone contribute roughly 69,000 and 31,000 deaths respectively. The researchers highlight the need for better early‑warning systems and stricter air‑quality standards to protect vulnerable populations.

In a separate effort to tackle persistent environmental toxins, a Spanish research team has engineered the bacterium Pseudomonas putida to degrade 2,4‑dinitrotoluene (DNT), a stable explosive residue. By inserting degradation genes and subjecting the microbe to nearly a year of adaptive evolution, the bacteria acquired dozens of mutations that enable them to use DNT as their sole nutrient source. This bioremediation breakthrough demonstrates a potential route to clean contaminated soils at former military sites.
