Change in the air
Figures show Royal Burgh now worse off
The state of air quality in Rutherglen and Cambuslang has been reversed.
Earlier this year Friends of the Earth Scotland released figures showing that Cambuslang Main Street had recorded 45 microgrammes per cubic metre of nitrogen dioxide in 2016, well above the European Ambient Air Quality Directive of 40.
However revised figures taken from the Scottish Air Quality website have shown the figures have come in at 39.3, just below the quality directive.
And the new numbers push Rutherglen above the threshold, going from 33.6 to 41.1.
Some of the revised numbers feature large swings, and were raised at a recent meeting of Cambuslang Community Council.
January, February and March 2016 remain the same in Cambuslang, however the nitrogen dioxide levels from April onwards change significantly. April has gone from 44 to 32. Nearly every month from then onwards shows a drop from the original numbers.
Particularly large drops were noticed in May, with a drop of 45 to 26 and June from 40 to 28.
The exception to the rule was November, which increased from 61 to 66.
The total numbers mean that the overall figure sneaks below the air quality directive’s acceptable range.
Rutherglen, however, is worse off than originally thought.
Several months have leapt up, with August going from 20 to 32, October from 25 to 42 and November from 30 to 54.
A Scottish Air Quality spokesperson said: “The automatic monitoring data within Scottish Air Quality Database go through a quality assurance/quality control process which involves ISO17025 accredited audits of the sites and then pulling together all the calibrations and site records, selecting the final scaling for the data and rejecting any unreliable data.
“During this process the data will be labelled as ‘provisional’ and the statistics quoted on the website may change depending on the processing we need to apply.
“The 2016 data for all sites on the website are currently going through the final stages of ratification and it is anticipated that they will be finalised by the middle of April.
“At this stage the data will be locked and labelled as ‘ratified’ and are unlikely to change from that point forward.”
Air pollution has been a growing concern in Rutherglen and Cambuslang over the past several years.
