Proficiency tests (PT) define the ability of the laboratory and/or analyst to carry out the procedures of the method with acceptable precision and accuracy. Participation in a...

This Standard Operating Procedure provides instructions for management of 3 L and 6 L ambient air samples which are taken on a routine, scheduled basis.

All glassware used in the analysis of toxic organic compounds at the trace and ultra-trace level must be scrupulously cleaned as soon as possible after use to ensure the removal...

The analysis of environmental samples for organic contaminants requires the use of a variety of organic solvents. These solvents vary greatly in flammability, volatility and...

The maintenance of a clean, safe workplace requires the participation of everyone working within the laboratory. The following procedures must be followed to ensure effective...

High pressure gas cylinders are used daily in the Analysis and Air Quality Section as carrier gas for gas chromatographs, reaction gas and makeup gas for instrumental detectors,...

Laboratory reagents are used in all procedural steps during the course of sample preparation. To ensure that reagents are of known quality and purity and free of contaminants...

This SOP describes procedures used to extract inorganic ions, organic acids, carbohydrates and water soluble metals from particulate matter collected on filters in support of...

We report a historical record of atmospheric deposition in dated sediment cores from Hasse Lake, ideally located near both currently and previously operational coal-fired power...

Erosion is important in the transport of heavy metals from terrestrial to fluvial environments. In this study, we investigated riverine heavy metal (Cd, Cu, Hg and Pb) dynamics...

The accurate determination of water quality criteria exceedance frequencies, distribution statistics (e.g., mean, median and percentile concentrations) and temporal trends in...

During May 2016 a very large boreal wildfire burned throughout the Athabasca Oil Sands Region (AOSR) in central Canada, and in close proximity to an extensive air quality...

Oil and gas exploration has disturbed extensive areas of grassland in North America. Reclamation of this human footprint is only a first step towards ecological recovery. A...

Rapid population growth and land-use intensification over the last century have resulted in a substantial increase in nutrient loads degrading marine and freshwater ecosystems...

In May 2016, the Horse River wildfire led to the evacuation of ∼ 88 000 people from Fort McMurray and surrounding areas and consumed ∼ 590 000 ha of land in Northern Alberta and...

The prevalence and seasonal variation of 7 viruses in 6 major rivers in Alberta were assessed using a combination of qPCR, cell culture and integrated cell culture with qPCR...

Over the last five decades, the Athabasca River Basin in Alberta, Canada, has been subjected to a wide range of environmental stressors from diverse human developments. This has...

Study region Surveys of stable isotopes of water in 50 boreal lakes were conducted during 2002–2017 as a component of Alberta’s Oil Sands acid sensitivity program in...

The Athabasca Arctic (AA) Watershed uses a data-management system called ACBIS (Aquatic Chemistry and Biology Information System) to store, track, verify, and distribute data to...

A reliable climate dataset is the backbone for modelling the essential processes of the water cycle and predicting future conditions. Although a number of gridded climate...
