Three locations in South Essex have been named as amongst the most polluted in the UK.

Southend, Grays, and Thurrock all exceed the World Health Organisation limit of 10 micrograms per cubic metre, which is determined as the point at which air quality could induce significant health problems such as heart disease, stroke, and lung cancer.

Southend was reported by WHO to have 11 micrograms per cubic metre, Grays 12 micrograms per cubic metre, and Thurrock 14 micrograms per cubic metre.

Clean air campaigners have urged the UK to take action after the report emerged, as the tiny air particles which come from sources such as transport, industry, coal plants, and burning material were announced to be responsible for the deaths of seven million people worldwide each year.

A spokesman from the department for environment, food, and rural affairs (DEFRA) said: "While air quality in the UK has improved significantly since 2010, this report from the WHO clearly shows the impact air pollution is having on the health of men women and children in the UK and across the world.

"Tackling this important issue is a priority for this government which is why we have a £3.5 billion plan to improve air quality and reduce harmful emissions and will set out further actions through a comprehensive Clean Air Strategy later this year."
