A major new study across Dublin has found high levels of a harmful air pollutant in the city centre and along some of the capital's major roads.
A thousand citizens measuring nitrogen dioxide from traffic over four weeks found the levels are within EU limits but some were just below the threshold.
Among the areas with the highest levels were along the quays, near Trinity College, in Phibsboro and by the M50 in Blanchardstown.
Anne Bedows collected data for the study in Phibsboro;
"It shows that overall Phibsboro is particularly badly affected by air pollution so we have levels that are three times over the limit that are recommended by the WHO and that stretches all the way to Mountjoy Square."
