Emerging Threats of Microplastic Contaminant in Freshwater Environment

Environmental challenges and solutions 2021 3 citations

AI summary Read the abstract

Researchers reviewed how plastic waste breaks down into microplastics that contaminate freshwater systems, warning that rivers and lakes — sources of drinking water for billions — are increasingly polluted with persistent plastic particles that resist natural degradation.

Study Type Environmental

The development of plastic brings world-shattering changes in industrialization, commercialization, and mankind and is now the most predominant widely used essential product. The disposal and degradation of plastic leads to the generation of microplastic and is a...

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 as Contaminant in Freshwater Ecosystem: A Modern Environmental Issue

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.

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.

Microplastics in Freshwater Environments: Sources, Fates and Toxicity

AI summary Read the abstract

Researchers reviewed the sources, environmental fate, and toxicity of microplastics in freshwater ecosystems, finding that microplastics cause physical injury and histological damage to aquatic organisms and act as vectors amplifying the toxicity of co-occurring chemical pollutants.

Status of Microplastic Pollution in the Freshwater Ecosystems

AI summary Read the abstract

Researchers reviewed the status of microplastic pollution in freshwater ecosystems, noting that only 7% of all plastic produced globally is recycled, leaving vast quantities to accumulate in rivers and lakes. These microplastic particles pose significant risks to aquatic life and potentially to people who depend on freshwater sources for drinking and food.
