Air monitoring.

AmC carries out Air Quality Measurements for environmental and occupational health monitoring. The laboratory specializes in all sorts of pollution of the working environment, indoor air, emissions, outdoor air and soil gas. Most of our air pollution analyses are accredited by the Danish accreditation body DANAK.

Ambient Air Monitoring

Air quality samples are generally collected for one or more of the following purposes:

  • To judge compliance with and/or progress made towards meeting ambient air quality standards.
  • To activate emergency control procedures that prevents or alleviates air pollution episodes.
  • To observe pollution trends throughout the region, including non-urban areas.
  • To provide a data base for research evaluation of effects: urban, land-use, and transportation planning; development and evaluation of abatement strategies; and development and validation of diffusion models.

With the end use of the air quality samples as a prime consideration, the network should be designed to meet one of four basic monitoring objectives listed below:

  1. To determine highest concentrations expected to occur in the area covered by the network;
  2. to determine representative concentrations in areas of high population density;
  3. to determine the impact on ambient pollution levels of significant sources or source categories; and
  4. to determine general background concentration levels.

These four objectives indicate the nature of the samples that the monitoring network will collect which must be representative of the spatial area being studied. Ambient air analyses are primarily related to determination of inorganic and few organic gases and vapors for which national or EU authorities have set limits. Sulphur dioxide, nitrous gasses, carbon oxide, and benzene are examples hereof. W use passive and active samplers and automatic analyzers for air quality measurements.

Occupational Health

AmC perform most analyses relevant for characterizing indoor air. These parameters typically require considerably lower detection limits than those required for occupational health analyses. An identification of the components is usually necessary in these cases, as it is not always the component with the largest content that causes problems. Our services include analysis of solvents, organic gasses and vapors as well as particles. Other analyses include heavy metal contents and other inorganic components, fibers and micro organisms.

In connection with all testing, we offer advice on the correct choice of sampling method, and we can also supply you with the necessary sampling equipment, pumps, etc. Most of our occupational health testing is performed as accredited testing. We are extremely flexible with regard to delivery times, and in cases of urgency we are always ready to perform rush analyses.

Soil gaseous

We perform soil gaseous measurements in the unsaturated zone of soil – i.e. the air between the surface and the groundwater. Soil gas investigations are primarily used as a fast and simple way of tracing and identifying volatile organic pollutants. The investigations are also aimed at measuring the contents of volatile micro pollutants in soil gas, allowing their influence on the indoor climate to be evaluated.

AmC offer accredited sampling and analyses of all relevant components such as chlorinated solvents and decomposition products hereof as well as of aromatic hydrocarbons – e.g. benzene, toluene, ethylene, and xylenes.

Meteorological data measurements

Understanding atmospheric processes and the phenomena that contribute to them requires detailed meteorological measurements, accurate data, and comprehensive analyses. AmC have staff and experience to help the clients in installation of the weather stations with different parameters to meet their meteorological measurements,, data, and analysis need. Our meteorological measurements and services include the following:

Field Measurements
AmC staff perform surface and upper-air measurements, data processing, and quality control services for use in routine monitoring and research studies.

Data Management
Experienced data analysts process and quality control data and develop databases for meteorological and air quality analyses.

Real Time Data Acquisition
AmC perform regularly collecting data from instrument networks and create web-based displays that allow clients and meteorologists to check instrument performance, forecast, and initiate enhanced sampling.

Data Analysis
AmC staff use surface and upper-air wind and temperature data to characterize atmospheric boundary layer meteorology and its influence on air pollution, dispersion, formation and transport. We use this information to develop conceptual and physical models of the processes that control air quality and to create air quality forecasting tools.

Quality Assurance
AmC meteorologists conduct system and performance audits of meteorological instruments that adhere to accepted assurance guidelines.
