Salford named and shamed for second highest levels of air pollution in the UK
The World Health Organisation has published its findings.
Salford has been named as one of the most polluted places in the UK, second only to the steel town of Port Talbot in Wales.
Data from the World Health Organisation (WHO) shows 47 towns and cities across the country match or exceed limits of air pollution.
Researchers looked at fine particle emissions - called PM 2.5 - which travel deeply into people's respiratory systems and can lead to health problems.
Many of the country's main cities exceed the WHO limit of 10 micrograms per cubic metre, including Manchester, Liverpool, London and Nottingham.
Salford recorded the second-worst levels of pollution in the UK, with 15 micrograms per cubic metre recorded, followed by Gibraltar and Thurrock on 14.
Manchester and Swansea were on 13, and cities including Leeds, Leicester, Liverpool, Plymouth, Sheffield and York recorded 12, one above London which showed 11 micrograms per cubic metre in 2015.
Eccles, Wigan and Warrington are also named in the report.
Cities on the WHO limit of 10 include Birmingham, Brighton, Bristol, Newcastle, Portsmouth and Southampton.
The most polluted city in 2015 according to the WHO data is Muzaffarpur in India, with a figure of 197 micrograms per cubic metre, although this figure is under revision.
Below that is Pasakha in Bhutan (150), Delhi in India (123) and greater Cairo in Egypt (117)
