Found 10 records similar to Enhanced Deposition, Polycyclic Aromatic Compounds (Active), Oil Sands Region
Environment and Climate Change Canada has been monitoring ambient air in the oil sands region for polycyclic aromatic compounds (PACs) using passive air samplers since November 2010. Ambient air samples collected using the established protocols of the Global Atmospheric Passive Sampling (GAPS) Network are termed passive PAC samples. Passive samplers are deployed for two-month periods across a network of 17 sites that are maintained by the Wood Buffalo Environmental Association. Average PAC levels across the passive sampling sites in the oil sands region are comparable to urban/sub-urban levels across Canada and are elevated compared with background rural sites in Canada.
Air emissions from oil sands development can come from a number of sources including industrial smokestacks, tailings ponds, transportation, and dust from mining operations. Air quality monitoring under the Joint Canada-Alberta Implementation Plan for the Oil Sands is designed to determine the contribution of emissions from oil sands activities to local and regional air quality and atmospheric deposition both now and in the future. Deposition data include:
Passive Sampling of PACs deployed for two month periods across a network of 17 sites
Active sampling of PACs at three sites to inform the amount of dry deposition
Particulate metals (24 hour integrated samples following the one in six day National Air Pollution Surveillance (NAPS) cycle)
Environment and Climate Change Canada (ECCC) has been monitoring trace metals in fine particulate matter (PM2.5) in the oil sands region since December 2010. Active PM2.5 sampling is collected at the Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations: Mannix (AMS5), Lower Camp (AMS11) and Fort McKay South (AMS13; until March 2015), using the established protocols and schedule of the National Air Pollution Surveillance (NAPS) Program. In 2015, sampling began for PM2.5 and PM10-2.5 (coarse fraction) at the Fort McKay (AMS1), Wapasu (AMS17) and Stony Mountain (AMS18) sites. The data from the measurements conducted so far show that concentrations of metals decrease with distance from the main surface mining and upgrading activities, and that the crustal elements iron, silicon, aluminum, and calcium are present in greater abundance than other metals detected.
Assess the importance of atmospheric deposition of contaminants as a contributor to ecological impacts of oil sands development and identify sources.
• Use snowpack measurements sampled across a gridwork to develop maps of winter-time atmospheric contaminant loadings for the region ~100 km from the major upgrading facilities
• Assess long-term trends in winter-time atmospheric deposition
• Determine the potential impact of wintertime snowpack mercury loads on tributary river water mercury concentrations (Spring Freshet) using Geographic Information System and hydrological modelling approaches
• Compare snowpack loadings to those obtained from precipitation monitoring and compare spatial patterns to PAC air measurements obtained from passive sampling network
Atmospheric concentrations and deposition rates of particulate elements are important indicators for determining the potential impacts of the oil sands industries on the local environment. The datasets consist of measured ambient air concentrations (in PM2.5 and PM2.5-10) and estimated deposition rates (based on PM10) of nearly 50 trace and major elements in the Athabasca oil sands region, Alberta, Canada. Data correspond to the years 2016 and 2017 for the following air monitoring stations: Fort McKay (AMS1), Buffalo Viewpoint (AMS4), Wapasu Creek (AMS17), and Stoney Mountain (AMS18), which are part of a larger network, monitoring various types of pollutants such as particulate matter, polycyclic aromatic compounds, etc. The samplers were operated once every three (AMS1, AMS4, and AMS18) or six days (AMS17) with a 24-hour sampling time (midnight-midnight) following the National Air Pollution Surveillance (NAPS) program protocol, set by the Environment and Climate Change Canada.
Verified and validated SPMD data are available on experimental research data to ascertain whether low concentrations of PACs can be more accurately detected using semi-permeable membrane devices than with water grab samples. Data are available from spring 2012 through winter 2014/15 from sites in the Athabasca, Peace, and Slave rivers, and within the Peace Athabasca Delta. Data are provisional and subject to change pending peer-review of the methods used as this is a relatively new technology and standard methods are not available. The calculated time-integrated dissolved concentrations generated from the SPMD samples are used to assess detection rates (percent of samples with concentration greater than the analytical level of quantification) for the same compounds measured in the water quality grab samples.
Total gaseous mercury (TGM) data are collected by Environment and Climate Change Canada at two Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations (AMS). The instrument at WBEA AMS 11 was relocated to WBEA AMS 13 in Spring 2014. TGM data from the oil sands region are available for: WBEA AMS 6 - Patricia McInnes, located in Fort McMurray, Alberta, starting in October 2010; WBEA AMS 11 – Lower Camp, located approximately 30km north of Fort McMurray, for the period December 2012 to March 2014; WBEA AMS 13 – Fort McKay South, located near Fort McKay, starting in June 2014. The TGM concentrations reported are comparable to those measured at sites across Canada (Cole et al., Atmosphere 2014, 5(3), 635-668).
The Pacific 2001 Air Quality Study (PAC2001) was conducted from 1 August to 31 September, 2001 in the Lower Fraser Valley (LFV), British Columbia, Canada. The study consisted of a number of research projects organized to address several issues related to ambient particulate matter and ozone. A special issue of Atmospheric Environment [Vol. 38(34), Nov 2004] describes the study objectives (Li, 2004) and the study results.
From August 10 to September 10, 2013, ground-based monitoring was significantly augmented at the Fort McKay South site (AMS13) to measure additional air pollutants and meteorological properties beyond what was available from the established long-term air quality monitoring in the area. This air monitoring study, undertaken in parallel with measurements from an aircraft flying over and downwind of the oil sands, was designed to gain a clearer picture of the mixture of air pollutants produced from different oil sands related activities and how they react and are transported in the atmosphere. These data are used to improve the capability of air quality models to determine current and future air pollutant levels and amounts of atmospheric deposition of pollutants over and downwind of the oil sands region. Periods of elevated pollutant concentrations were observed; however, none of these surpassed the current short duration (hourly, 8 hour or 24 hour) federal and provincial standards.
Total gaseous mercury (TGM) data are currently collected by Environment and Climate Change Canada at two Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations (AMS). Preliminary, hourly averaged TGM data from the oil sands region are available for: WBEA AMS 6 - Patricia McInnes, located in Fort McMurray, Alberta, and 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 TGM. The monitoring follows the established Canadian Air and Precipitation Monitoring Network (CAPMoN) standard operating procedures.
