Inside the Particulate Monitor – the Triboelectric Method Bengt Löfstedt AQM 2024-02-23 View Count 1087 We’ve seen in previous blog posts that particulate concentrations can be measured by filter-based techniques as well as by some different optical methods. However, it doesn’t stop there. Let’s also have a look at a principle based on the electrical charges of particles – the triboelectric method. Read More »
Inside the Particulate Monitor – Optical Methods Bengt Löfstedt AQM 2024-02-09 View Count 1376 Particulate concentrations can be measured in a variety of ways. We’ve discussed filter-based methods in a preceding article and now it’s time to have a look at optical techniques. Read More »
Inside the Particulate Monitor – Filter Samplers Bengt Löfstedt AQM 2024-01-29 View Count 1319 Particulates in ambient air is one of the major types of air pollution, causing severe health problems in many locations around the world. Legislators have therefore imposed concentration limits and require the particulates to be monitored. But how does a particulate monitor work? Read More »
Air Pollution Part 4 – Reduction Methods Bengt Löfstedt General, AQM, CEM 2023-12-07 View Count 1548 Air pollution is undesirable but there are ways to fight it. We wrap up the series of articles about air pollution by taking a look at what to do about it. Read More »
Air Pollution Part 3 – Sources of Particulates Bengt Löfstedt General, AQM, CEM 2023-11-30 View Count 1742 In this article, we take a closer look at how particulate matter is generated, with emphasis on the smallest fractions which also are the ones with the worst health effects. Read More »
Air Pollution Part 1 – What’s in the Air? Bengt Löfstedt General, AQM, CEM 2023-11-16 View Count 1561 What is air pollution, where does it come from, and what can we do about it? This article is a first in a short series addressing these topics. Read More »
Clean Air Matters! Svante Wallin General 2016-02-15 View Count 5655 New research presents facts about the consequenses of polluted air, and PM2.5 in particular. Air pollution is causing 5 millions of premature deaths per year according to scientists. Read More »
