Resumo
The geometric increase in the production and exploitation of plastics
worldwide has several advantages as well as disadvantages due to the mismanagement
of plastic waste. These waste products find its way into the aquatic body.
Microplastics are plastic particles with its longest diameter less than or equal to
5 mm. Their microscopic nature, irregular color and morphology have made their
extraction from the buoyant organic materials problematic. This work documents for
the first time, the sampling and sample extraction of microplastics in Nigeria. An optimized
sampling and sample extraction protocol for surfacewaterwas developed. The
extraction protocolwas developed in a laboratory study using a simulated sample that
mimics the environmental sample (microplastics+organic materials). A micronized
LDPE (<300 μm) was used for the study and yielded a percentage recovery rate
of 82%. The digested microplastics which were subjected to SEM analysis showed
a slight change in the surface morphology. Thereafter, the environmental sample
was extracted using the developed laboratory protocol and a high positive result was
achieved. This protocol improved NOAA’s method of extraction by excluding the
use of microscope for the final extraction, which, of course, will yield a biased result.
This was achieved by the addition of ethanol to the final solution.
