To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.
To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.
Air quality monitoring for regulatory purposes requires instrumentation, systems and procedures that meet international standards such as those described by the USEPA, MCERTS or the European Union. Ecotech offers solutions that meet this criteria.
Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide (CO2), carbon monoxide (CO) and volatile organic compounds to particulates, humidity and bacteria such as legionella. CO2 is one of the greatest variables affecting indoor environmental quality since it is produced by people occupying...
Ambient air quality monitoring is the systematic, long-term assessment of pollutant levels by measuring the concentration and types of certain pollutants in the surrounding, outdoor air. Some of these pollutants (commonly called ‘Criteria Pollutants’) are considered hazardous to human health and their levels are regulated by government agencies around the world, including the US EPA. Teledyne API provides a complete line of ambient air quality monitoring instruments, including those for both gas and...
The sustainability and environmental impact of a new build house is typically assessed using BREEAM. Part of the BREEAM assessment method is determining the air quality inside the house.
Gradko can supply a range of products for qualified BREEAM assessors. We try to work with qualified BREEAM assessors to determine and meet their requirements.
The products we normally supply are used for monitoring formaldehye and VOC levels in new build properties.
To protect humans and the environment from damage by air pollution, it is of the utmost importance to measure the levels of pollutants in the air. Real time monitoring of dangerous gases is particularly interesting in hazardous areas, as the conditions can change dramatically very quickly, with serious consequences. ADVANTICSYS employs its knowledge in wireless sensor networks to develop customized solutions for our customers.
Motor vehicle emissions are a major source of air pollution in urban areas and impact the lives of billions of people every day around the world. Motor vehicle exhaust contains toxic chemicals that are harmful to people’s health when exposed at certain levels. These toxic fumes cause smog in the atmosphere, which can affect very broad regional air sheds and contribute to the formation of cancer. Teledyne API has several products specifically designed to meet the challenging demands of near-roadside air...
Continuous Emissions Monitoring Systems (CEMS) are used to measure flue gases from stationary sources at a wide variety of regulated industrial facilities, including power plants, petroleum refineries, petrochemical plants, waste incinerators, pulp and paper producers, and many others. The types of air pollution measured from these sources vary widely based on the industry and process, and many are regulated by government agencies around the world.
Ambient air monitoring involves the measurement of `representative` air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring.
Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring.
Production of semiconductor materials require extremely clean air supply that help ensure the quality of the materials being manufactured as well as specialized gases to enable production to occur smoothly and efficiently. Teledyne API carries a complete line of Industrial gas process instruments including those that both produce and measure gases in these unique applications. Teledyne API also provides specialty gas instruments designed to help reduce or eliminate Airborne Molecular Contamination (AMC) in the...
Mobile monitoring (on foot) around an urban route to understand personal exposure
Monitoring pollution at different levels up an urban high rise building to understand exposure with windows open
Assessing employee pollutant exposure with indoor/outdoor air quality monitoring
based in Stratford-upon-Avon, UNITED KINGDOM.
Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.
OPSIS provides real-time, flexible monitoring of particulate matter in the ambient air. Particulate matter monitoring with OPSIS, is a cost-effective solution, is ideally suited for use in modern monitoring stations. It can be remote controlled and includes automatic calibration, features that frees time. The SM200 meets the new regulation for automatic monitoring of PM10 and PM2.5. It also meets the new regulation for particulate matter sampling on filter membranes for further analysis of cadmium, nickel, PAH...
