Gravimetric Air Sampling
Air quality assessments help to quantitatively evaluate the fraction of harmful material in the air. In many industries, this may be a legal requirement to ensure standards are being met or to determine the effectiveness of control strategies.That’s why Air Quality Sensors / Air Quality Monitors are used Protect the environment Employers must take all […]
Farming and Pollution
The rise of large-scale factory farms in recent years has raised questions about their impact on surrounding areas. What pollutants are they putting into the air? Researchers from the Earth Institute at Columbia University found that where farm emissions combine with industrial waste and vehicle pollution this leads to the creation of harmful aerosols. Particulate […]
NO₂ in London
London has some of the highest levels of street pollution in the world. Oxford Street, a busy shopping zone, is one of London’s worst affected areas, with high concentrations of nitrogen dioxide (NO2) recorded. This pollutant is produced when fossil fuels are burned. Oxford Street is particularly badly affected owing to the volume of traffic on […]
Introduction to Air Sampling
Air Sampling involves drawing a known volume of air through a filter, trapping the contaminants and measuring the amount of contaminant captured. Introduction to Air Sampling The results are usually expressed as a concentration, calculated by dividing the volume of air by the amount of contaminant captured. To calculate the volume of air, you multiply the […]
Whose pollution anyway?
The weather impacts air quality. It comes as no surprise, then, that many of the world’s most polluted cities are awkwardly situated from climatic perspective. In Santiago, Chile, where air pollution regularly exceeds critical levels, scanty rain and low wind speeds prevent atmospheric mixing from taking place, causing a build-up of smog. The city’s striking […]
Low Emission Zones
Poor air quality is known to be the most significant environmental cause of premature death in the EU. This disturbing fact also extends to many other countries around the world. Initiatives to combat this issue are therefore a priority for many governments. The implementation of a Low Emission Zone (LEZ) is one such initiative. LEZs aim to improve […]
Energy Security
No longer are renewables the sole preserve of the environmentally minded. Technological advances have improved efficiency and reduced costs, helping to restore faith in the clean energy market. For many, investment in this sector has proved extremely profitable. Countries and corporations are seeking new ways to innovate and rationalize without having to mine, frack or […]
Corporate Citizenship
Good businesses ensure that workers are happy and healthy – productivity depends on it. Low satisfaction, medical complaints and absenteeism affect employee performance and reduce output. Where legislation exists protecting workers’ health and well-being (as it does in much of the world), it should be viewed not as a minimum legal requirement but as a […]
Embassy Monitoring
For a little under a week Chai Jing’s Under the Dome eluded censors. The controversial documentary, which explores China’s air pollution crisis, amassed hundreds of millions of views across the country. Speaking directly to a Chinese audience, Chai Jing confronts some uncomfortable truths. She combines shocking imagery, statistical data and the touching story of her own daughter […]
Indoor Air Quality
Air quality is a significant concern for homes and businesses alike. The technological and material demands of modern life mean that more and more pollutants are being released into the atmosphere. Unknowingly we breathe in a host of noxious particulates and trace gases, many of which can adversely affect our health. Though shielded from vehicular […]
