8. Environmental Chemistry: Tracking Contamination
Environmental chemists use advanced analytical tools such as Fourier-transform infrared spectroscopy and Raman spectroscopy to detect and identify microplastics in rain and snow samples.
These methods allow researchers to differentiate synthetic polymers from naturally occurring particles, providing precise data on contamination levels.
Careful analysis helps scientists trace the distribution and likely sources of microplastics, as well as assess their potential environmental impacts.
