Microplastic Pollution in the Shore Sediments of Narmada River Along Jabalpur City
AI summary Read the abstract
Researchers characterized the abundance and physical properties of microplastics in shore sediments along a 50 km stretch of the Narmada River through Jabalpur City, India, collecting samples from four sites. The study provides baseline contamination data to inform pollution management and highlights implications for both aquatic organisms and potential human health effects.
Microplastics, due to their microscopic size, constitute a concern to aquatic species since they are easier to consume and the recent discovery of microplastic in human blood shows that these may also have undisclosed health effects on humans. This study provides microplastic characteristics and abundance of microplastics in the shore sediments of Narmada river flowing along Jabalpur City. The information about the presence of microplastics can be crucial in preventing further pollution and developing management interventions. Sediments samples were collected from 4 sites along a 50 km stretch of the river. Sample pretreatment was performed using ZnCl2 solution for density separation and H2O2 for oxidation of organic material. Microplastics examination was carried out using Fourier Transform Infrared Spectroscopy (FTIR). Microplastics in the 20-1000 μm size range were found to be more abundant (114-273 MP/Kg) than larger microplastics in the 1-5 mm size range (18-110 MP/Kg). This research presents the first accounts of microplastic pollution in the shore sediments of Narmada River and it emphasizes the need for more in-depth research into microplastic pollution in fresh water sources.

Distribution and characterization of microplastics in Narmada River: Insights from differently impacted anthropogenic zones of upper and middle basin in Central India
AI summary Read the abstract
Scientists found tiny plastic particles called microplastics throughout India's Narmada River, which millions of people depend on for drinking water. The plastic pollution was worst near tourist areas and semi-urban zones, with 19 different types of plastics detected, including some that are especially harmful to health. This matters because these microplastics can end up in our drinking water and food chain, potentially affecting human health.
