Quality of air over Ireland not affected by ash cloud
Environment chiefs monitoring pollution levels insisted today the volcanic ash had not affected air quality over Ireland.
The Environmental Protection Agency (EPA) said there were no traces of sulphur dioxide at any of its monitoring stations around the country.
"Monitoring of this information today has not shown any increase in pollution as a result of the ash cloud," an EPA spokesman said.
The agency said special air quality tests were being carried out at Ringsend, Dublin, Newbridge, Co Kildare and Ennis, Co Clare but no changes have been recorded.
The EPA spokeswoman added: "There have been no reports of any changes in our air quality since this event.
"We have not had any reports of dust to our offices (Dublin and Wexford) and the real time monitoring of sulphur dioxide levels would also pick up changes in dust levels."
The EPA said it would continue to monitor air quality closely.
High concentrations of sulphur dioxide can cause temporary breathing problems for asthmatics and is a major factor in the cause of acid rain.
