Special Report No. 18-02: Review of Ambient Air Monitoring Technology for PM2.5 and Associated Canadian Ambient Air Criteria

PDF , Source: Special Reports Published: 02/2018 View Abstract

Abstract: Most Canadian ambient air quality standards and criteria for PM2.5 were derived from epidemiological data collected during the 1980s and 1990s. Older ambient air PM2.5 monitors are known to yield biased measurements when compared to those obtained from the newer reference gravimetric-based instruments. Although it is conceivable that these biases may have affected the accuracy of the epidemiological associations reported in the literature, the available information summarized in this report suggests that other methodological and confounding factors may have more impact on health effect estimates, and thus on ambient air criteria derived from these estimates, than monitoring technology.

Special Report No. 18-01: Species at Risk Assessment in Canada: A Cross-Jurisdictional Review

PDF , Source: Special Reports Published: 02/2018 View Abstract

Abstract: In 1992, Canada signed and ratified the International Convention on Biological Diversity, the key purpose of which is the protection and conservation of the world’s flora and fauna. Conserving species at risk is a vital part of the maintenance of biodiversity. As a party to the Convention, Canada has committed to the identification and protection of species at risk, and each jurisdiction within Canada has committed to work together with the federal government to do the same within their respective regions. That said, given that natural resources and land-use decisions fall under the jurisdiction of provincial and territorial governments, the way in which species at risk are assessed, categorized, and managed may vary. The purpose of this report is to review the species at risk assessment and management mechanisms used across Canada by the federal, provincial, and territorial governments, and to examine the role science plays in helping to ensure assessments and listings are objective, transparent, and science-based. While most jurisdictions within Canada have some mechanisms for recognizing and managing species at risk, only some have dedicated legislation for that purpose, and one jurisdiction has no specific species at risk programs at all. While species at risk management varies significantly across the country, it is a complex undertaking with multiple elements to be considered. Biological and ecological science plays a key role in helping in the assessment, recovery, and ultimately the long-term conservation of species at risk.
