It's interesting to know that atmospheric pollution is now being researched and taken seriously. Unlike in the 1950s, when pollution from domestic coal-burning brought about the Clean Air Act, I think pollution from cars and aircraft (though, I suspect, every bit as toxic) has been ignored simply because it's not clearly visible at street level. We're still building ever more roads, motorways and airport runways. When are the powers-that-be going to face reality?

Incidentally, the link you've posted isn't working for me. Is the article behind a paywall?

Please try the link now - I think it was borked by some unnecessary smart quotes. Sorry!

Oh, I somehow manage to do that all the time when posting links, too. It's usually because I've typed '2' instead of a quotation mark before the URL. Anyway, it's working now. Some of those pollution-levels are absolutely appalling, aren't they? I'd be interested to know what the count is in my street as, during the day, it's filled from end to end with traffic in both directions, and the high tenements on each side produce a canyon effect. I might discover another reason to move elsewhere as quickly as possible!

That's fascinating.

Wow, that is really cool! Thank you for sharing.

We're working on a kit with the University of Sheffield, so this is mega relevant to our interests and great work :-)

That's very interesting ... and scary!
