First record of microplastics in the endangered marine otter (Lontra felina)
AI summary Read the abstract
Researchers documented the first evidence of microplastic ingestion in the endangered marine otter (Lontra felina) by detecting plastic particles in fecal samples collected along the Peruvian and Chilean coasts, indicating that microplastics have entered coastal food webs reaching this apex predator.
Lontra felina inhabits the coast of Peru and Chile frequently closed to human beach resorts and shing ports which are common focus of anthropogenic pollution like solid waste and plastics are part of this as persistent material. In consequence the habitat for L. felina reduce its quality and indirect potential intake of plastic is a high risk. Here we present the rst documented evidence of the occurrence of microplastics in the scats of L. felina. This evidence gives a rst insight on the trophic transfer of microplastics in the marine web, where top predators like L. felina are also included.

Microplastics in Biota
AI summary Read the abstract
Microplastics have been detected in biota across marine, freshwater, and terrestrial ecosystems, demonstrating their ability to enter food webs at multiple trophic levels. Their omnipresence in living organisms raises concerns about bioaccumulation of both the plastic particles and the chemical additives and adsorbed pollutants they carry.
Microplastics in Biota
AI summary Read the abstract
Researchers summarized evidence that microplastics have infiltrated living organisms across marine, freshwater, and terrestrial ecosystems, posing a broad threat to biodiversity. Their persistence in biological tissues means they can accumulate up the food chain, ultimately reaching humans through diet.
The Effects of Microplastic Pollution on Marine Organisms and its Impact on Human Health: A Review
AI summary Read the abstract
Researchers reviewed how microplastics affect major marine taxa — from plankton to marine mammals — documenting impacts including reduced growth and reproduction, behavioral disruption, and inflammatory responses, while also assessing pathways through which MP-contaminated seafood and drinking water translate ocean pollution into risks for human health.
Microplastics as Pollutants in the Marine Environment
AI summary Read the abstract
Researchers reviewed the pathways and consequences of microplastic pollution in marine environments, focusing on how post-consumer plastic waste breaks down and accumulates across ocean ecosystems. The review underscores the widespread ecological risks posed by microplastics to marine life, with potential implications for human health through seafood consumption.
Microplastics in the Marine Ecosystems: Identification and Impacts
AI summary Read the abstract
Tiny plastic particles called microplastics, broken-down bits of everyday plastic waste, are showing up along India's coastlines, and this review paper rounds up what scientists have found so far. While research on their health effects is still catching up, these particles are known to persist in the environment and can enter the food chain through seafood, raising concerns about long-term exposure for coastal communities. The authors point out that India still needs a lot more research to fully understand how serious this problem is and what it means for people's health.
