ETC staff participated extensively in the development of the Canada-Wide Standard
(CWS) for particulate matter and ozone. The choice of metrics for the CWS was based
largely on data analysis carried out by the ETC using data collected from the NAPS
network. Reports were prepared on rollback relationships for PM and ozone and on
trends in PM and ozone. Staff participated in the CWS Monitoring and Reporting
Workgroup and helped prepare documents on Achievement Determination and on a Monitoring
Protocol.
Ambient Air Measurements for PM and Ozone
ETC staff prepared a plan to enhance current monitoring activities for PM and ozone
and participated in a federal provincial working group set up to address monitoring
and reporting issues related to the CWS.
PM2.5 Filter Weighing
14.2 Benzene
ETC staff participated in the Development Committee for the Benzene Canada-Wide Standard,
attending numerous meetings and participating in conference calls and a public
consultation session. A report was prepared under contract on emission trends for benzene
and data were assembled for a socio-economic analysis of the benefits of reducing benzene
levels in ambient air.
Ambient Air Measurement for Benzene
Benzene is being measured at more than 40 sites across Canada. A report was prepared
summarizing data collected from 1989 to 1998 and trends in ambient benzene levels were
examined. This report has been posted on the website of the Canadian Council of Ministers
of the Environment (CCME).
Analysing Ambient Air for Volatile Organic Compounds (VOCs)
14.3 Polychlorinated Dibenzo Dioxins and Furans (PCDD/PCDF)
Ambient Air Measurements for PCDD/PCDF
PCDD and PCDF are being measured at 15 sites across Canada.
14.4 14.4 Petroleum Hydrocarbons in Soil
ETC staff members participated in the development of the Canada-Wide Standard for Petroleum
Hydrocarbons in soil (PHC CWS) that was 'championed' by Alberta. ETC staff co-chaired the
Development Committee, chaired the Analytical Method Technical Advisory Group (AM-TAG), and
served on the Ecological TAG. The ETC also developed and implemented the oil fractionation
protocol used to produce the feedstock material for the biological tests that were the
foundation for the ecological risk assessment component of the Standard. The ETC also
performed a single-laboratory validation of the Reference Method and coordinated a multi-
laboratory validation through the Canadian Association for Environmental Analytical Laboratories
(CAEAL). The Canadian Council of Ministers of the Environment (CCME) signed the Standard in
early 2001.
