Change in the air

Fig­ures show Royal Burgh now worse off

Rutherglen Reformer - - Gossip Girl - Jonathan Ged­des

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.

Air we breathe The level of pol­lu­tion on Cam­bus­lang Main Street is not as bad as first thought
