Water quality and ecosystem health data collected using a risk-based monitoring approach to support the Great Lakes Water Quality Agreement are included in this dataset. By conducting regular, systematic measurements of the physical, chemical and biological conditions of the Great Lakes...

As part of the research activities of the St. Lawrence Action Plan (SLAP) and in collaboration with Parks Canada, a 5-year monitoring program was initiated to assess the effect of metal and element contamination to clams in the Tadoussac area. The sites of concern included marinas near...

The Fish Contaminants Monitoring Program (FCMP) was initiated in 1976. The objective is to collect a variety of biological samples in freshwater environments for the purpose of determining ecosystem contaminant levels. Environment and Climate Change Canada (ECCC) collects biological samples from...

This study is focused on measuring lead in environmental matrices (surface water, sediment and tissues of recreational fish species) at locations known for high levels of recreational fishing activities (i.e. locations with high uses of lead in fishing sinkers and jigs) to determine the fate and...

The toxic effects of a representative mixture (mining activities) of rare earth elements are studied in the hydra, an organism particularly sensitive to these elements. All data are a part subject of a publication containing method details, full QA/QC, interpretation and conclusions. Citation:...

The objectives of the present long‐term study, spanning a 45 year period, were to 1) investigate the temporal trends of total mercury (THg; muscle and liver) and selenium (Se; liver) in ringed seals (Pusa hispida) from different regions of the Canadian Arctic; and 2) examine possible...

Communities in east Hudson Bay and James Bay are concerned about ecosystem changes observed in recent decades, particularly related to sea-ice conditions, and also about potential impacts of contaminants from long-range atmospheric transport and regional human activities. The Arctic Eider...

Monitoring is conducted by Environment and Climate Change Canada (ECCC)...

Long-term freshwater quality monitoring data for sites in the Maritime Coastal basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) and...

Long-term freshwater quality monitoring data for sites in Newfoundland and Labrador (NL) for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Parks Canada. Environment and Climate Change...

Long-term freshwater quality monitoring data for over 12 sites in the Saint John and St. Croix River basins for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate...

Water quality and ecosystem health surveillance and monitoring data collected to complete assessments of beneficial use impairments of Areas of Concern (AOCs) and to track the effectiveness of remedial measures and confirm restoration of beneficial uses are included in this dataset. AOCs are...

Water quality and suspended sediment monitoring and surveillance data collected from the connecting channels of the Great Lakes to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment...

Sediment quality data from the Great Lakes collected to determine baseline status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment quality objectives and identify emerging issues are included in this dataset.

Water quality and ecosystem health data collected in the Great Lakes and priority tributaries to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with water quality objectives and identify emerging...

Water quality and ecosystem health data are collected in the nearshore zone of the Great Lakes to address the problem of nuisance benthic algae. Monitoring data include physical and chemical water quality data as well as biological data, primarily from Cladophora and dreissenid mussels on the...

Particle data from Canadian and U.S. ground-based monitoring networks from 1982 forward include the following: Aerosol Optical Depth (AOD); Aerosol Size Distribution; Aerosol Number; Aerosol Chemical Composition; Particulate Matter Mass; Particulate Matter <= 2.5 microns (PM2.5);...
