Found 10 records similar to Anthropogenic Organic Pollutants in Precipitation
This data collection contains metals data in precipitation measured at sites in Canada.
For additional data on pollutants in precipitation, also see the data collection of Anthropogenic Organic Pollutants in Precipitation. For additional data on metals, also see the data collection of Particulate Metals.
This data collection contains air concentration data (in both gas and particle phases) of anthropogenic organic pollutants in air (AOPA). Some of the AOPAs in air reported in this data collection, are considered toxic substances (e.g. polychlorinated biphenyls, PCBs; polycyclic aromatic hydrocarbons, PAHs; some flame retardants; and some organochlorine pesticides, OCs). These data come from monitoring sites in Canada.
This data collection contains particulate metals data measured at sites in Canada.

Major ions data consist of the following key ions in precipitation: Cl-, NO3-, SO4=, NH4+, Na+, K+, Ca++, Mg++. The data sets typically also include the pH and depth of the precipitation sample. These data are collected by several provincial, national and bi-national networks. The wet-only precipitation collector samples precipitation only when it rains or snows.
Measurements of the concentrations of air pollutants (Nitric oxide + Nitrogen dioxide - NOx, Sulfur dioxide - SO2, Ozone - O3 and PM2.5) were made at Resolute (2013-2017), Cape Dorset (2013-2017) and Pond Inlet (2018-), in addition to basic meteorology (wind speed and direction, temperature, humidity). The primary objective was to investigate the impact of increasing ship traffic on the air quality in northern communities, in support of Arctic Air Quality model development as well as policy work for the International Maritime Organization. A secondary objective was to evaluate the impact of community diesel power plants on the local air quality. Data consists of quality-controlled 1-minute averages, calibrated in post-processing against traceable standards.
The Nitrogen Scoping Study consisted of 14 different field campaigns, each of 3-7 weeks duration undertaken between November 2001 and March 2005 at 8 sites of the Canadian Air and Precipitation Monitoring Network (CAPMoN). The objectives of the study were: (1) to characterize the ambient concentrations of oxidized and reduced nitrogen species at CAPMoN sites, (2) to estimate the contribution of the different nitrogen species to nitrogen wet, dry and wet+dry deposition at CAPMoN sites (with a view to understanding which nitrogen species should be added to the CAPMoN suite of measurements) and (3) to measure the size distribution of various inorganic ions in particulate matter at CAPMoN sites. The resultant data sets provide short-term characterizations of air quality at the 8 rural/remote locations in Canada and are provided in collaboration with the National Atmospheric Chemistry (NAtChem) Database and Analysis Facility of Environment and Climate Change Canada.
The Canadian Air and Precipitation Monitoring Network (CAPMoN), operated by Environment and Climate Change Canada (ECCC), is designed to study the regional patterns and trends of atmospheric pollutants such as acid rain, smog, particulate matter and mercury, in both air and precipitation. The network began operating in 1983. CAPMoN updated and replaced two older networks known as the Canadian Network for Sampling Precipitation (CANSAP) and the Air and Precipitation Network (APN). The integration of APN as part of CAPMoN extended the data record as far back as 1978.
The atmospheric monitoring subcomponent of the Northern Contaminants Program (NCP) studies long-range transport of anthropogenic organic pollutants in air (AOPA), mercury, and chemicals of emerging arctic concern from around the globe. This subcomponent includes three NCP Core Monitoring Projects, namely “Northern Contaminants Air Monitoring: Organic Pollutant Measurements”, “Mercury Measurements at Alert and Little Fox Lake”, and “Passive Air Sampling Network for Organic Pollutants and Mercury”. Long-term air measurements of contaminants are collected continuously throughout the year. In addition, there are several passive air sampling stations across the Arctic.
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.
Ground level ozone measurements, sometimes referred to as in situ measurements are those measurements that occur close to the ground, i.e. within the boundary layer which is approximately 1 kilometre in height. Ongoing network measurements from the Canadian Air and Precipitation Monitoring Network (CAPMoN) and studies such as those from Alert, NU and Mount Sutton, QC are also included within the published data sets. In CAPMoN, measurements are made every minute and averaged at five minute intervals.
