Identification, characterisation of microplastic and their effects on aquatic organisms
AI summary Read the abstract
Tiny plastic bits called microplastics are building up in rivers, lakes, and oceans, and fish are absorbing them into their bodies, with the amount varying by fish species, which body part, and what they eat. This review pulls together existing research on how scientists detect these particles and how they affect aquatic life, which matters to us because these same fish often end up on our dinner plates, potentially passing microplastics up the food chain to humans.
Due to global warming, drought, population growth and industrialisation, existing water resources are rapidly being depleted and polluted. Pollution caused by millions of plastic waste reaching water resources seriously threatens the aquatic environment. This manuscript reviews the current state of knowledge about microplastics in the aquatic ecosystem, their analysis and detection methods, and their effects on aquatic organisms. In addition to the measurement methods, alternative new methods and the relevant findings for MPs, including abundance, size, shapes, colours and polymer types are summarised considering the literature. In addition, the effects of microplastics on the aquatic ecosystem especially fish had been evaluated. In the light of the completed researches, it is understood that abundance and size of MP s are connected with fish species, tissue type and feeding regime. KOH for the digestion in tissues and fenton reagent for sediment samples were found as more suitable techniques. FTIR and Raman spectroscopy were more advantaged because they are not only fast – easy but also have repeatable specifications.

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."

AI summary Read the abstract
Researchers reviewed the growing body of evidence on how microplastics harm aquatic ecosystems, finding that long-term exposure damages organisms at multiple levels — from delivering toxic chemicals to disrupting reproduction — and calling for urgent action to reduce plastic leakage into waterways.
