Searching for traces in the atmosphere

24 marzo 2015

4th generation halogenated coolants and foaming agents have only been in use for a few years. They have replaced persistent greenhouse gases such as R134a, which were used in (car) air conditioning units, refrigerators and in a variety of foams. Researchers have now published first measurements on the atmospheric distribution and abundance of these new substances. They show that the new coolants are frequently used in Europe — and that their use is increasing.
