See the comparison with the EU (and World Health Organisation) pollution limit in the graphs. Basically the annual average in Bedminster is double what it should be compared with current health standards.
We all need fresh air and our politics needs a breath of fresh air. Government figures show that 30,000 people die prematurely because of air pollution, including 200 Bristolians, each and every year. Locally the main cause is our heavy road traffic. It's a major public health issue - especially for children and those with existing health problems. I have been campaigning on it for decades (see the Bristol Post news clip from 26 years ago in 1989 at the bottom of this blog entry; also see here where I co-campaigned with Deb Joffe in 2015).
