Abstract
The most common kind of marine trash in the
greater lakes and our ocean is plastic. Plastic waste comes in a variety of forms
and sizes, but the term “microplastics” refers to particles that are smaller
than five millimeters. Global interest in commercial species polluted with
microplastics (MPs) and mesoplastics is growing because of the possible effects
on food safety and human health. This study was conducted to study the
likelihood of mesoplastic contamination and MPs in Oreochromis niloticus,
a species that has significant commercial value and was collected from the lakes
of Ambattur, Korattur, and Madhavaram. Three hundred fishes were analyzed over
a period of six months, from October 2022 to March 2023. It was found that the
guts and gills of these fishes possessed more mesoplastics (74), of which 58%
were films and fragments, and more MPs (48). Higher levels of MPs pollution were
observed in korattur lake. This research has proved that the gut of fish had
the highest concentration of MPs. Further in the present study four distinct
types of polymers—polythene, polypropylene, polyester, and polyamide—were also
identified. These findings made it evident as to how contaminated fish tissues
had microplastics in each of the three lakes. In order to minimize plastic
pollution in the freshwater environment, extensive efforts are required. MPs
present in fish could have negative impacts on environment and human health.
These findings would establish a baseline of data regarding the contamination
of MPs in freshwater commercial fish species.
