Microplastics in silver catfish (Chrysichthys nigrodigitatus) from new Calabar River in Niger Delta, Nigeria

Abstract

This study investigated the ingestion of microplastics by silver catfish (Chrysichthys nigrodigitatus) from New Calabar River in Niger Delta, Nigeria. Microplastics from the guts of 45 fish were examined with microscope after dissolution with potassium hydroxide. Microplastics, mostly fragments were found in about 56% of the samples at an average of 3.87±5.97 particles per fish. This study highlights the consequences of plastic pollution in freshwater environment and the potential risk to aquatic and human life. This also shows a potential threat to public health and therefore needs attention from health and environmental policy makers.
