In a major breakthrough, American researchers have found a method to be able to trace the origin and the destination of forever chemicals.
Why in the news?
Researchers used a technique which involves magnetic fields and radio waves to track the spread of forever chemicals in the ecosystems across the globe.
The technique involves passing samples through a strong magnetic field then reading the burst of radio waves their atoms emit.
This reveals the composition of carbon isotopes in the molecule and gives the chemical its fingerprint.
About Forever chemicals:
Forever chemicals are scientifically known as per-and polyfluoroalkyl substances (PFAS).
These chemicals are generally useful in applications such as water-proofing, heat resistance, detergents, food packaging and non-stick technologies.
They are known to stay in the environment virtually forever and contribute to environmental degradation which adversely impacts the health of all organisms including human beings.
