520 |a"In 1988 the Canadian Council of Ministers of the Environment identified increases in the concentration of ground-level ozone in populated areas as the primary air quality problem in Canada (CCME Report, 1990). The Lower Fraser Valley of BC which includes portions of Greater Vancouver was singled out as one of three non-attainment areas in Canada where ozone concentrations exceed the maximum acceptable air quality objective of 82 ppb during summer months. It has been shown that levels in excess of this threshold adversely affect human health and reduce the yield and vitality of crops and forest ecosystems. For these reasons the Government of Canada included in its Green Plan a proposal to provide air quality advisories which would give 24 hour notice of the expected occurrence of high concentrations of ground-level ozone in excess of the maximum acceptable threshold to citizens living in non-attainment are"--Introduction, page [1].
