THIRD pollution spike hits Colnbrook this week as airText issues SIXTH alert for year!

If you go outside, no deep breaths today.  airText, the air pollution forecaster, issued its SIXTH alert for Slough this year yesterday evening.  The alert coincides with VERY HIGH pollution levels recorded at Colnbrook Lakeside for the third time this week.


defra’s forecast for today

AirText has issued an alert for MODERATE air pollution across Slough today.  The alert coincides with high pollution levels being recorded in parts of Greater London and in the East and new measures being talked about to protect children across London.

But locally the picture could be even worse, with extremely high levels of particulate matter currently being recorded at Colnbrook Lakeside this week.


The situation at Colnbrook Lakeside at 6am this morning (25th January)

A pollution reading of Very High (maximum 10 out of 10 rating) was registered this morning at Colnbrook Lakeside Osiris 2 for extremely high particulate levels over a 24 hour mean.  At 2,598µg/mthey are, once again, way beyond levels officers at Slough said should be impossible in 2013.  Three enormous spikes in the so far unratified figures have been recorded this week coinciding with warnings across the country.


The official reason for the pollution spike is “the continuing high pressure and associated light winds”.

Foggy conditions – responsible for the cancellation of over 100 flights at Heathrow yesterday and further disruption expected today – is also locking in particulates in the air.

And beware those striking sunsets we have seen: the high cloud mixed with particles of nitrogen dioxide is causing those.

Pollution levels are expected to be above normal until Thursday, although defra expects a vast improvement by tomorrow.

In 2016 AirText issued 18 alerts for the entire year.  Its first alert last year was not issued until March.
