EU cuts toxic air limits but still falls short of WHO guidelines

The European Union has agreed to set stricter limits on the toxic particles and dangerous gas that dirty its air, but will not aim for the levels that doctors and economists recommend.

The new rules slash the yearly limits for fine particulates known as PM2.5 – which wreak havoc on the whole body because they are small enough to slip into the bloodstream – from 25 µg/m³ to 10 µg/m³, and for nitrogen dioxide, a gas that hurts the lungs, from 40 µg/m³ to 20 µg/m³.
