Microplastics as Contaminant in Freshwater Ecosystem: A Modern Environmental Issue

2019 2 citations

AI summary Read the abstract

Microplastics have permeated freshwater ecosystems globally, degrading ecological integrity and entering food webs through ingestion by aquatic organisms at multiple trophic levels. The contamination of freshwater environments is particularly concerning because these systems serve as drinking water sources and are integral to food production for human populations.

Study Type Environmental

Plastic pollution emerged as an environmental problem during last quarter of twentieth century. This emerging pollution in aquatic ecosystems is degrading the food web and ecological integrity and posing hazardous effects on the environment. Plastic debris,...

Microplastics as Contaminant in FreshWater Ecosystem: A Modern Environmental Issue

AI summary Read the abstract

Microplastics have become a pervasive contaminant in freshwater ecosystems, disrupting food webs and threatening aquatic biodiversity through ingestion, chemical leaching, and physical harm to organisms. As freshwater systems are primary sources of drinking water and food, microplastic contamination in rivers and lakes carries direct implications for human health.

Microplastic Pollution in Freshwater Systems: A Potential Environmental Threat

AI summary Read the abstract

Microplastics smaller than 5mm are emerging as a significant contaminant of concern in freshwater systems, where they fragment further, adsorb chemical pollutants, and accumulate in organisms across multiple trophic levels. The pervasive contamination of rivers, lakes, and drinking water sources poses mounting risks to aquatic biodiversity and human health, demanding urgent regulatory attention and improved waste management.

Microplastics in freshwater ecosystem: A serious threat for freshwater environment

AI summary Read the abstract

Researchers reviewed microplastic distribution, toxicity, and transport in Indian freshwater ecosystems, finding that rivers like the Ganges are significant conduits of plastic pollution to the ocean and that microplastics can adsorb co-pollutants such as heavy metals, compounding harm to aquatic organisms.

Microplastics: A Significant Threat to Freshwater Ecosystems

AI summary Read the abstract

This review assessed the mounting threats microplastics pose to freshwater ecosystems, noting that with only 7% of global plastic recycled annually, particles accumulate in rivers, lakes, and groundwater where they impair aquatic organisms through physical blockage, chemical toxicity, and pathogen transport. Freshwater systems are both critical biodiversity habitats and the source of drinking water for billions of people, making their contamination by microplastics a direct threat to human health through water consumption and food.
