Assessment of Microplastics in the Gastrointestinal Tract of the Indian Major Carps from Periyakulam, Kurichi and Singanallur Lakes of Coimbatore, Tamil Nadu, India
Summary
This study examined microplastic contamination in the digestive tracts of three commercially important carp species from three lakes in Coimbatore, India. The presence of microplastics in food fish from these lakes — likely from nearby waste dumping — raises concerns about ecosystem health and food safety.
The investigation of microplastics has been carried out among Indian Major Carps from three lakes of Coimbatore, India. The gastrointestinal tract of fishes were isolated and examined to detect the presence of microplastics. The fishes of Indian major carps viz., Catla catla, Labeo rohita and Cirrhinus mrigala were used in this study. Three lakes were selected namely Periyakulam Lake, Kurichi Lake and Singanallur Lake in Coimbatore district, India. The microplastics samples were confirmed with Bruker – Alpha FTIR ATR spectrophotometer in order to confirm plastics functional groups. The presence of microplastics in the fish from the sampling locations may be due to unmonitored dumping of wastes in the water. The presence of microplastics may affect the growth of fish which leads to poor commercial value. The future research should be aimed to evaluate the impact and the risk of microplastics to the fishes, environment as well as to human beings.
