Air Analysis – Multimedia

In this infographic, we explore different types of air pollutants, sources of air pollution and key techniques used to monitor these compounds.

Scientists report preliminary work calculating how inequities in air pollution exposure fluctuate from day to day across 11 major U.S. cities, which may be exacerbated by climate change in some places.

In this episode, Lucy Lawrence interviews Pascal Lemberge an applications specialist at Thermo Fisher Scientific.

Researchers have developed a new personal air-sampling system that can detect more than 100 different compounds in one device.

Air pollution monitoring is a very important topic to protect human health. Many standards regulate the emission of fuel powered vehicles like automotives (cars, trucks, motorcycles), boats, etc. or industrial sources of air pollution. In particular, ultra-fine particles such as soot particles can accumulate in the lung are classified as carcinogenic, but also asthma, allergies, cardiovascular and respiratory diseases are caused by fine dust. Filter weighing is a back-weighing method to determine the level of air pollution.

The compound ozone, a known respiratory irritant, exists in high concentrations at flight altitudes, making the “fresh air” sucked in by air conditioners at those heights, well, not so fresh. In fact ozone exposure may be responsible for many of the short-term discomforts we associate with air travel.

A number of pollutants found in the air we breathe are known to have harmful effects on human health and the environment. Consequently, correct monitoring of air quality is of great importance.

It might feel like they’re making us cooler, but refrigerators and air conditioning are actually making our world warmer. In this episode of Untold, we consider how we might keep ourselves and our food cool, without accidentally warming up our world.

In this episode, the team discusses the growing movement for sustainable science. Research has a yeti-sized ecological footprint, and here we follow the tracks from ozone-destroying CFCs and energy-guzzling freezers through to a new future for science that promises to make labs eco-friendly at last.

A drop in nitrogen dioxide emissions correlated to the nationwide quarantine in China in January 2020. Two months later the emissions are increasing.
