Restrictions in the utilization of polybrominated diphenyl ether (PBDE) mixtures have led to the increased usage of alternative flame retardant additives in a wide range of commercial applications. The present study examined the occurrence of established and emerging flame retardants (EFRs) in fish from a densely-populated urbanized sector of the St. Lawrence River (Montreal, Quebec, Canada). Thirty-eight PBDE congeners and sixteen EFRs were determined in fish belonging to three predatory species (yellow perch, northern pike, and muskellunge). The bioavailability of these EFRs in human-impacted aquatic ecosystems warrants further environmental assessment and toxicity testing.

Two vertical seismic profile (VSP) surveys were acquired in the vicinity of a 1-km deep VMS deposit in the Abitibi Sub-province of northwestern Quebec. One VSP survey intersected massive sulfides and recorded P-waves and converted S-waves from the deposit.

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM) are currently collected by Environment and Climate Change Canada at a Wood Buffalo Environmental Association (WBEA) Air Monitoring Station (AMS). Preliminary, three-hour averaged speciated mercury data from the oil sands region are available for WBEA AMS 13 – Fort McKay South, located near Fort McKay, Alberta. There are no Environment and Climate Change Canada or Canadian Council of Ministers of the Environment (CCME) air quality guidelines, nor Alberta Ambient Air Quality Objectives for speciated Hg measurements. The monitoring follows the established Canadian Air and Precipitation Monitoring Network (CAPMoN) standard operating procedures.
