Dundee is in the top six most polluted streets for nitrogen dioxide in Scotland, breaking the legal limit.

A new study by Friends of the Earth Scotland ranked Dundee's Seagate fourth, with 43 microgrammes per cubic metre, followed by Lochee Road, with 42 microgrammes per cubic metre.

The legal limit for nitrogen dioxide was set by the European Ambient Air Quality Directive at 40 microgrammes per cubic metre.

The environmental group analysed official 2017 air pollution data and Glasgow's Hope Street was again ranked Scotland's dirtiest street.

Air pollution campaigner for Friends of the Earth Scotland, Emilia Hanna, said: "The situation across Scotland is potentially showing some slow signs of improvements but filthy streets continue to poison our lungs nearly a decade after a legal deadline.

"Air pollution from traffic fumes has a devastating impact on health, especially on children and people with existing health problems.

"It is responsible for over 2500 early deaths every year in Scotland and costs the Scottish economy over £1.1bn annually."

In 2016, the Scottish Government announced a Low Emission Zone will be launched in Glasgow by the end of this year, followed by three more in Dundee, Edinburgh, and Aberdeen by 2020.

Buses, vans, lorries, cars and taxis will have restricted access in theses zones aiming to lower the pollution levels.

Ms Hanna continued: "Low Emission Zones will make a real difference and will improve the health of children growing up in polluted areas.

"These Zones must be ambitious in their design, apply to the right vehicles and be supported by measures to make public transport, walking and cycling the smarter choice for everyone."
