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:...

Long-term freshwater quality data from federal and federal-provincial sampling sites throughout Canada's aquatic ecosystems are included in this dataset. Measurements regularly include physical-chemical parameters such as temperature, pH, alkalinity, major ions, nutrients and metals. Collection...
