Levels of the airborne pollutant PM10 (micometre-scale particulates) found at the Hope Street monitoring station have increased to 35 micrograms per cubic metre of air in the last year (A rise of 7 so I think that's a 25% increase).
PM10's cause coughing, wheezing and shortness of breath and probably worse if you have asthma, bronchitis or other lung diseases.
A council spokesperson blames the high result on the proximity of the monitoring station to the taxi rank and annual variations in the weather and says it's ok because most people would have "limited exposure" to the toxic soup.
The Scottish Executive has placed a blanket ban on any G8-related material being released under the Freedom of Information Act. The presumption against release (the opposite of what it's supposed to be, and ineligible for appeal to the FOI commissioner) covers any documents the Executive currently has but also those that it will have in the future. The order is to last indefinetly.
