Microplastic Pollution in Marine Environment: Occurrence, Fate, and Effects (With a Specific Focus on Biogeochemical Carbon and Nitrogen Cycles)
AI summary Read the abstract
Marine sediments have emerged as major sinks for microplastic particles, where they disrupt biogeochemical carbon and nitrogen cycling in ways that could alter the ocean's capacity to regulate climate. The interference with nutrient cycles adds a systemic ecological dimension to microplastic pollution beyond the direct toxicity effects on individual organisms.
The pollution of microplastics is becoming increasingly serious, and rising evidence shows that the marine environment, especially sediments are major sinks of these plastics. So far, microplastic particles have been reported as widespread in large quantities in...

Microplastics in the Marine Environment: Sources, Distribution, Biological Effects and Socio-Economic Impacts
AI summary Read the abstract
Researchers reviewed the sources, distribution, biological effects, and socioeconomic impacts of microplastic pollution in marine environments, finding that rivers and estuaries are the primary land-to-ocean transport pathways. The review emphasizes that microplastics transfer adsorbed pollutants and additives through food webs to top predators, and that reducing plastic production and improving waste management are essential long-term solutions.
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.
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.
Marine Microplastics: Abundance, Ecotoxic Consequences of Associated Anthropogenic Contaminants and Interactions with Microorganisms
AI summary Read the abstract
Researchers reviewed the rapid growth of microplastic pollution in the ocean, highlighting how these particles accumulate toxic chemicals and interact with microorganisms in ways that amplify their ecological harm. As plastic production continues to rise, the marine food web faces increasing exposure to contaminated microplastics that can ultimately reach humans through seafood.
Occurrence, Fate, and Biodegradation of Microplastics in Marine Environments
AI summary Read the abstract
Researchers reviewed how microplastics — synthetic polymer fragments smaller than 5mm — spread through marine environments, persist over long periods, and undergo partial biodegradation. The widespread distribution of these particles in oceans raises ongoing concerns about their effects on marine life and the humans who eat seafood.
