Abstract
Microplastics (MPs) and nano plastics (NPs)
are worldwide pollutants affecting the environment - marine, freshwater aquatic
or terrestrial/ aerial. The plastic generated waste has the potential to
pollute the sea, water bodies, rivers and laker and fishes. Therefore,
theseresearch aimed to analyse microplastics contamination in three species of
fresh water eatable fishes in the Andhra Pradesh and Telangana areas of paleru
lake and Krishna river coastal areas. The sampling was carried out for 4 Month
from september to december 2025 at three locations, namely paleru reservoir
(sample station-1), krishna river in Vijayawada (Sample station-2) and Costal
area of Krishna (Sample station-3). The fish sample Catla (Catla catla),
Rohu (Labeo rohita) and Hilsa (Tenualosa ilisha). The find the
result were four forms of microplastics, namely microbeads, nurdle and
microfibers with five types of colours, include block, brown, blue, yellow and
read. The dominant shape and colour were nurdle and red, respectively. In Rohu
fish, the highest and lowest number of microplastic particles were found in
sample in paleru reservoir (3.12 particles/fish) (sample station-1) and Krishna
river water (2.90 particles/fishe). Meanwhile, Catla caltla had the highest and
lowest abundance in Costal area of krishna (4.32 Particles/fish) and Krishna
River Vijayawada Krishna River water (2.80 particles/fishe), respectively. In
general, Catla fish had a higher abundance of microplastic than the other two
species, and microplastics were highest in fish from Krishna River near urban
areas station-2. According to Gas Chromatography and Mass Spectrometry (GC-MS)
test on flesh sample, namely nylon and polyproplene. In this study the flesh of
species analysed were contaminated with microplastic.
