Wild Amphibian and Wetland Health and Contaminants, Oil Sands Region

Water chemistry, 26 different metals, and polycyclic aromatic compounds (PACs) were measured at 21 wetland sites where studies of amphibian health are being conducted. The water chemistry measurements (pH, conductivity, total dissolved solids, etc.) are used to further assess water quality, characterize the wetlands studied, and allow for comparisons among the different types of boreal wetlands being monitored.

The data show low concentrations of metals, with many of the individual metals at undetectable levels. Two water quality samples, one from 2011 (with an arsenic concentration of 8.27 µg/L) and one from 2012 (arsenic at 6.47 µg/L) from Galoot Lake, located in the Peace-Athabasca Delta, exceeded the guideline for arsenic established for the protection of aquatic life by the Canadian Council of Ministers of the Environment (5.0 µg/L; CCME). However, samples collected from this same location in 2013 (1.29 and 0.78 µg/L) and 2014 (2.21 µg/L) were below the CCME guideline.

Passive sampling techniques, such as the deployment of semipermeable membrane devices (SPMDs), are being used in this monitoring program to monitor PACs in boreal wetlands. The highest concentrations of PACs were detected in SPMDs deployed within a 25 km radius of surface mining activity, consistent with the pattern revealed by snow deposition studies of PACs in the region. Field investigations continue to evaluate the health of wild amphibian populations at varying distance from oil sands operations.

d4PDF-WaveHs: the first SMILE-based ensemble of global historical wave height

The d4PDF-WaveHs dataset represents the first single model initial-condition large ensemble (SMILE, 100-member) of historical significant ocean wave height (Hs) at a global scale. It was produced using an advanced statistical model with predictors derived from Japan's database for policy decision-making for future climate change (d4PDF) ensemble of historical simulations of sea level pressure. d4PDF-WaveHs provides 100 realizations of Hs for the period 1951-2010 (hence 6,000 years of data) on a 1° x 1° latitude-longitude grid. In addition, this dataset contains 14 statistics (including extreme indices) calculated on monthly, seasonal, and annual scales.

d4PDF-WaveHs provides unique data to understand better the poorly known role of internal climate variability in ocean wave climate. For example, it can better distinguish climate variability from trend signals. It also provides a better sampling of the entire probability distribution, including the tails where extreme events occur. This is crucial to properly assess wave-driven impacts, such as extreme sea levels on low-lying (and densely) populated coastal areas. This dataset may interest a variety of researchers, engineers, and stakeholders, including those in the fields of climate science, oceanography, coastal management, offshore engineering, and energy resource development.

Life-cycle exposure of Fathead minnows to environmentally relevant concentrations of the B-blocker drug Propranolol

Propranolol is a human pharmaceutical b-blocker that has been detected in municipal wastewater effluents in low concentrations. To assess the potential of this compound to affect fish, Fathead minnow (Pimephales promelas) were exposed for a life cycle in a flow-through system to nominal propranolol concentrations. During the 162-day to 165-day exposure, no significant changes in weights or lengths were seen in Fathead minnows, although the highest concentration of propranolol did cause a 15% decrease in survival of larval and juvenile stage fish compared with controls. At maturity, there were no significant changes in condition factor, liver-somatic index, or secondary sex characteristics in propranolol-exposed male or female fish. Female gonadosomatic index was significantly decreased in fish exposed to the highest concentrations of propranolol, probably because of increased egg-laying. Propranolol exposure caused no effects in Fathead minnows, except at the highest exposure concentration, where there were slight decreases in survival of juvenile minnows, and indications of increased reproduction. The present study is important because it is the first to assess the potential for effects in fish exposed to propranolol for a life cycle.

The Chemicals Management Plan (CMP) is a Government of Canada initiative aimed at reducing the risks posed by chemicals to Canadians and their environment. A key element of the Chemicals Management Plan is the monitoring and surveillance of levels of harmful chemicals in Canadians and their environment. Monitoring and surveillance are essential to identify and track exposure to hazards in the environment and associated health implications. Monitoring and surveillance programs provide the basis for making sound and effective public health and environmental health policies and interventions, as well as measuring the efficacy of control measures. 

In support of the Chemicals Management Plan, monitoring and surveillance initiatives were established to support Health Canada and Environment and Climate Change Canada scientists, in collaboration with external partners and researchers, to advance our knowledge. This initiative has allowed the Government of Canada to increase its commitment to a number of existing monitoring initiatives, as well as to support new efforts.

Stratospheric Ozone and Ultraviolet (UV) Radiation

On-going monitoring of the total column ozone and spectral ultraviolet radiation (UV) in Canada is carried out by the Canadian Brewer Spectrophotometer Network (CBSN). The data are used for periodic assessment of the state of the ozone layer, satellite data validation, and in forecasting ECCC’s UV Index. The UV Index values are derived from spectral UV measurements. All locations make total column ozone and spectral UV measurements using Brewer spectrophotometers. Vertical profiles of ozone are ozone mixing ratios as a function of height. They are measured by the Canadian Ozonesonde Network. The data are used for periodic assessments of the ozone layer, various research applications, and satellite validation. All locations measures vertical profiles by launching balloons carrying ozonesondes into the stratosphere, usually once per week. Both total column ozone, UV and ozonesonde data are available from the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) (https://www.woudc.org/), which is hosted by Environment and Climate Change Canada.

The Turkey Lakes Watershed Study

The Turkey Lakes Watershed (TLW) Study was initiated in 1980 by Environment Canada, Natural Resources Canada and Fisheries and Oceans Canada to evaluate anthropogenic perturbation of Canadian Shield ecosystems. Originally, the Study focused on the aquatic and terrestrial effects of acid rain, but now it includes research into the effects of other anthropogenic pollutants (e.g. toxic contaminants) and ecological perturbations (e.g. forest harvesting, climate change and fish habitat modification).


Supplemental Information


Intensive monitoring of meteorology, atmospheric deposition, hydrology and water chemistry within the TLW has permitted determination of water, ion, and nutrient budgets for both its terrestrial and aquatic components. The data permit detection of ecosystem trends and inference of cause. The health and status of both the terrestrial and aquatic biological communities (species distributions, production, standing stocks, etc.) have been determined also. Specific hydrological research questions such as the definition of water pathways during snowmelt have been considered. Hydrological, chemical and biological models have been developed and validated using TLW data and these have been used to simulate watershed responses at other locations. The basin has also acted as a base for related regional studies (e.g. water chemistry surveys, water bird population and distribution studies), and research is now branching to include evaluation of the effects of other airborne pollutants (e.g. metals and toxic organic contaminants), other system-level perturbations (e.g. UV-b and climate change), and specific landscape manipulations (e.g. forest harvesting and aquatic habitat alteration).

The Climate Change and Air Pollution (CCAP) program was established in 2016 to identify the severity and extent of adverse impacts of current and future air emissions on aquatic ecosystems to support regulatory actions and policy development. The program includes a number of components, including identifying, monitoring and defining air quality and greenhouse gas (GHG) concerns; improving our understanding of the short- and long-term effects of atmospheric pollutants on the environment; developing a plan to combat climate change; and monitoring and reducing both domestic and transboundary emissions of GHGs. The program is also responsible for identifying and studying emerging issues including multipollutant impacts, major urban sources, and effects of increasing heat on air pollutant formation, among others. 


On-going cooperation and support with the Provinces and Territories, international governments and organizations and academia are vital to deliver these priorities to Canadians.

Speciated Mercury Monitoring

Ambient concentrations of speciated mercury (Hg) have been measured at many locations across Canada. Mercury in the atmosphere is measured in three operationally-defined forms - gaseous elemental mercury (GEM), reactive gaseous mercury (RGM), and particulate-bound mercury (PBM). Under most conditions, GEM (or Hg0) is the predominant species in the air (~95-99%), while RGM and PBM concentrations are typically two orders of magnitude lower, i.e., lesser than 5% of the total atmospheric mercury concentration (Schroeder and Munthe, 1998). Reactive gaseous mercury is thought to consist of compounds such as HgCl2, HgBr2, Hg(OH)2 (Lin and Pehkonen, 1999), although the exact composition is unknown.

Field Exposure and Effects-Air Emissions-PAHs, Oil Sands Region

Avian Health and Contaminants

 Data on tree swallow clutch size and nestling weight, wing length, organ size, and measures of thyroid function were collected from study sites near active mine pits, tailings ponds and processing plants on oil sands leases in Alberta, and at relatively undisturbed reference sites south of Fort McMurray, Alberta. Analysis of the birds’ reproductive performance has revealed that neither hatching success nor fledging success differed between industrial and reference sites.

 PAHs, alkylated PAHs, and dibenzothiophenes were measured in tree swallow nestling tissues and fecal samples. Tree swallow nestlings on the industrial sites had higher or comparable PAH concentrations in both their muscle and fecal samples, compared to tree swallow nestlings on the reference sites.

 Ambient air quality samples collected from these same sites revealed concentrations of volatile organic compounds (VOCs) including polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, and dibenzothiophenes. Data show concentrations at the industrial sites were equal to or higher than those measured at the reference sites.

 Additionally, PAHs, alkylated PAHs, and dibenzothiophenes were measured in water samples collected from wetlands adjacent to the tree swallow study sites. Data show concentrations at the industrial sites were equal to or greater than concentrations from reference sites but did not exceed Canadian Council of Ministers of the Environment (CCME) water quality guidelines for the protection of freshwater aquatic life.
