Bioavailability and toxicity of microplastics to zooplankton

Ecotoxicological Effects of Microplastics in Marine Zooplankton

AI summary · Read the abstract

Marine zooplankton ingest microplastics, mistaking them for food, which reduces feeding, impairs reproduction, and can transfer particles up the food chain. Because zooplankton form the base of marine food webs, their ecotoxicological responses to microplastics have cascading consequences for ocean ecosystems and human seafood consumers.

Toxicity and Possibility of Microplastic Exposure While Living

The occurrence of microplastic in aquatic environment and toxic effects for organisms

AI summary · Read the abstract

"This review synthesized global research on microplastic occurrence in aquatic environments, finding that microplastics are widespread across all water bodies and can trigger inflammation, impair reproduction, and carry co-contaminants such as heavy metals, organic pollutants, and additives into organisms via bioaccumulation. The evidence underscores the need for stricter plastic emissions standards and improved water management, as aquatic microplastic pollution directly cascades into human dietary exposure through seafood and drinking water."

Environmental Fate and Effects of Microplastics on Organisms

AI summary · Read the abstract

This review examined the environmental fate of microplastics — including fragmentation dynamics, sorption of co-contaminants, and bioaccumulation through food webs — alongside their toxic effects on organisms ranging from invertebrates to mammals. Understanding how plastics persist, concentrate toxicants, and biomagnify through trophic levels is essential for predicting long-term health consequences for wildlife and human consumers.

Ecotoxicological Consequences of Microplastics in Aquatic Life

AI summary · Read the abstract

Researchers reviewed how microplastics — tiny plastic particles under 5mm — harm aquatic ecosystems, documenting that fish, invertebrates, and other marine life can ingest them, leading to physical damage, toxic chemical exposure, and disruptions to feeding and reproduction.
