Description

To obtain timely data for the purpose of air quality assessment, air quality trend reporting, air quality index reporting and to meet the requirements for inclusion of the data in provincial and national air quality databases, a continuous method of analyzing Ozone concentration in ambient air samples is used. This method is capable of measurement updates at a rate of once every five minutes or faster. Readings from instruments of this method enables the calculation of hourly averaged concentration of ozone. Commercially available ozone analyzers are used in the method.

Description

For the purpose of collection of ambient air samples for determination of polyaromatic hydrocarbons (PAH), Polychlorinated biphenols (PCB’s), dioxins and furans, and pesticides a high volume sampler is used for this method with a polyurethane foam (PUF) cartridge. Typically samples are collected on the National Air Pollution Surveillance (NAPS) schedule, every six days. Results will not be immediate but rather in the form of laboratory results, days or even weeks later. PUF samplers are named as such because they use a plug of polyurethane foam to trap the target compounds that exist in the vapour phase. A particulate filter is also used to collect the sample in the particulate phase and trap dust and prevent deterioration of the foam.
