S Collins queries the accuracy of the estimated 698 people who died due to air pollution in South Yorkshire in 2014, (Star letters, November 30).

The data is produced annually by Public Health England based on long-term exposure to particulate air pollution.

It will always be estimated data due to other variable health factors.

But it has been vital to have data for consideration in making decisions on IKEA and now Smithy Wood.

In objecting to the proposed service station at Smithy Wood, Sheffield Green Party noted the buffer that it provides for Chapeltown and Ecclesfield residents from traffic noise and fumes from the M1.
