Air quality monitoring results for 2010 released29 August 2012
FREDERICTON (GNB) – Air quality continues to improve throughout New Brunswick for most pollutants, according to 2010 air quality monitoring results released today.
"I am pleased to report that the air quality health index expanded to Fredericton and Moncton from Saint John in 2010, and that the risk level remained low more than 97 per cent of the time at all three sites, and with the risk level never exceeding moderate at any of the three locations," said Environment and Local Government Minister Bruce Fitch. “This shows that continuing efforts to maintain and improve air quality are making a difference in the lives of all New Brunswickers."
The year 2010 was the achievement deadline for the Canada-wide Standard (CWS) agreement on fine particulate matter and ground level ozone. New Brunswick has achieved CWS levels at all monitored sites.
Today's report is the 14th annual and summarizes air quality monitoring data recorded at the Department of Environment and Local Government's 17 ambient air quality monitoring stations and 12 acid rain monitoring stations. It also includes data from 38 industry-operated ambient air quality monitoring stations.
● There were no exceedances of objectives for nitrogen dioxide or carbon monoxide at any of the provincial monitoring sites.
● There were no exceedances of total reduced sulphur (TRS) in Saint John in 2010, which is an improvement from the four exceedances reported in 2009.
● Volatile organic compounds (VOCs), monitored in Saint John, remained well below guideline levels.
● Acid rain concentrations declined. The year had the lowest concentrations recorded since the provincial government began the acid rain monitoring program in 1986.
● Compliance with sulphur dioxide objectives exceeded 99 per cent during the year throughout New Brunswick.
The report is intended to provide the public with a convenient summary of air quality results, with emphasis on air quality assessment in relation to standards and objectives. Long-term trend data are also presented for representative sites.
In New Brunswick, air quality objectives for carbon monoxide, sulphur dioxide, hydrogen sulphide, nitrogen dioxide and total suspended particulates are set under the Clean Air Act. Acid rain, fine particulates, ground level ozone and VOCs are also monitored.
Copies of the report are available on the Department of Environment and Local Government website.
