Air Advisory

September 17, 2012--
The Sydney Tar Ponds Agency is reporting an air exceedance of Benzo(a)pyrene at its Victoria Road air monitoring station. The sample, taken over a 24-hour period on Friday, August 31st, 2012 showed a concentration of 1.11 nanograms per cubic metre (ng/m3). The Minister of the Environment 24-guideline adopted for the cleanup work it 1.1 ng/m3.

There was site activity on the day the sample was taken.  The air monitoring station was not downwind of project activities when the sample was recorded.

Benz(o)pyrene is an odourless, polycyclic aromatic hydrocarbon (PAH) typically distributed during the incomplete combustion of fossil fuels. It is present in automobile and diesel exhaust, and can be produced by various activities such as backyard fires, coal burning, and cigarette smoke.

Ambient air monitoring has been conducted around the sites since 1989 using fixed air monitoring stations strategically placed in nearby locations. They operate every six days and measure air quality for a 24-hour period, corresponding with the six-day National Air Pollution Surveillance (NAPS) schedule. All historical data is available on the Agency’s website, www.tarpondscleanup.ca
