How do filters remove particles from the air and reduce exposure - especially the small ones? As this Risk Bites primer shows as it dives into the science of aerosol particle capture, it may not be how you think! Air filters are an important tool for protecting health, improving air quality, and
Air pollution has many causes. The biggest polluter is energy production, with two-thirds of particulate emissions coming from coal-fired power plants. Road traffic and factory farming in agriculture also contribute to this. Author: 3sat/nano/Labo M/Johan von Mirbach/Chris Caliman/Christoph Valenti
There is lots of traffic in our cities. The private car remains a popular means of transport. Our explanatory video shows the problems that urban traffic leads to and possible solutions. Translation and dubbing: alugha
There are various methods for measuring radioactivity in the air. With the help of trace analysis, even very low concentrations of radioactivity in the air can be detected. In the video, Jacqueline Bieringer explains how to detect radioactive substances in the air. Original: "Federal Office for Rad
A global effort to monitor air quality is in the works as the US, Korea, and the European Union prepare to launch geostationary satellites capable of monitoring pollutants and other aerosols. Visit http://science.nasa.gov/ for more. Click here to see more videos: https://alugha.com/NASA
Be it road traffic, neighbors or air traffic: three out of four people in Germany are bothered or annoyed by noise. Our video explains the causes of noise, the effects of noise and how we can reduce it. You can find more information about noise on the UBA website www.umweltbundesamt.de at https://ww
Droughts claim more victims each year than any other natural disaster. Depending on where it occurs and how long it persists, the cost of a drought can run into the billions of dollars. Droughts cause more than economic hardship, however. As this video segment adapted from NASA's Goddard Space Fligh
Adverse weather conditions seriously disturb air traffic. Thunderstorms in particular often cause delays – pilots consider these storms among the most hazardous phenomena in air traffic. Up until now, however, air and ground personnel have lacked the appropriate technical systems to provide them wit
When air is in motion, wind is created. Temperature differences are responsible for this. When air warms up, it rises and colder air flows in. This is the cool wind that we feel. There is almost always wind on the coasts. Author: ZDF/Pur+/Autorenkombinat/Tobias Schönke/Carina Schulz/Jochen Schmidt
When warm, humid air rises and cools down at the equator, the moisture condenses into clouds and it starts to rain. When it sinks again, the air warms up and causes extreme dryness, forming tropical deserts. Author: ZDF/Terra X/I.Zink/Wendevarga/Jochen Schmidt Translation and dubbing: alugha Cli
All over the world, we humans are responsible for blowing very many gases and substances into the air that are harmful to the climate. The most harmful to the climate is energy consumption. It's followed by agriculture, forestry and industry. Author: ZDF/logo/Romy Geiger Translation and dubbing: a
Sailing uses two propulsion effects: Drag and lift in combination. Wind pressure and air flow are responsible for the movement. Author: ZDF/Pur+/Autorenkombinat/Tobias Schönke/Rita Gerhardus-Faust/Jochen Schmidt Translation and dubbing: alugha Click here to watch more videos: https://alugha.com/T
