Microplastics are tiny plastic particles and
fragments that are less than 5 millimeters in size.
These particles can be found in various
environmental compartments. They are a growing
concern due to their potential environmental
impact and the challenges they pose for ecosystems
and human health. Microplastics can vary in shape,
composition, and size, with some being so small
that they are not visible to the naked eye (nano
dimensions). This diversity makes the detection
and analysis of microplastics a complex scientific
field.
When conducting microplastics analysis, it is
essential to choose the appropriate combination of
instruments and techniques based on the sample
type, and expected particle sizes.
Additionally, methods for the analysis of
microplastics are still being developed and have
not been brought to the level of standards. Like all
other methods of analysis, this procedure involves
the extraction of particles from the matrix [1] and ...
then an analysis that enables the confirmation of
the identity of the polymer from the point of its
particle composition. Particles that are mixed
polymers also often appear. That is why it is most
practical, and at the same time the most expensive,
to have several different techniques to determine
the type of particles. Everything gets complicated
when applied to micro and nano particle sizes.
Today, different instrumental techniques are
used for the detection of microplastics, depending
on the dimensions of the particles to be identified.
FTIR Spectrometer works by measuring the
absorption of infrared light by the sample,
providing information about the types of polymers
present. Raman Spectrometer is uses the scattering
of laser light to provide information about the
molecular structure and composition of
microplastics. SEM with Energy-Dispersive X-ray
Spectroscopy (EDS) capable to visualize the
surface morphology of particles and when coupled
with EDS, it can also provide information about the
elemental composition of the particle. Micro Raman spectrometers are specialized for
micrometar sizes particles. Pyrolysis instrument
and GC-MS system that burns microplastics and
this products are analyzed using GC-MS.
None of these techniques have been accepted as
standard so far. And this will probably be decided
for a long time, because the particle sizes are in a
very wide range and not all of these techniques are
sensitive and reliable enough for particles of micro
and nano size. The choice of technique will also be
influenced by the way the results are expressed
