Review on microplastic studies in Brazilian aquatic ecosystems

Microplastics in Brazilian aquatic ecosystems and seafood: An updated review

AI summary · Read the abstract

This review pulls together 100 studies to show that Brazil's rivers, bays, and coastal waters are widely contaminated with tiny plastic particles called microplastics, mostly from clothing fibers and packaging. Seafood like fish, shellfish, and crustaceans are absorbing these particles, sometimes in huge amounts, which raises real concerns for anyone eating fish from these waters. The bigger picture: plastic pollution levels swing a lot depending on rainfall and tourist seasons, and scientists still need better, more consistent testing methods to fully understand how much risk this poses to human health.

Microplastics in Aquatic Environment

Environmental perspectives of microplastic pollution in the aquatic environment: a review

AI summary · Read the abstract

Researchers reviewed how microplastics spread through freshwater and marine environments worldwide, finding they accumulate in sediments, absorb toxic chemicals, and create surfaces where antibiotic-resistant and potentially pathogenic bacteria can thrive. This pollution threat reaches even Antarctica and the deep sea, posing risks throughout aquatic food webs.

Microplastics in Aquatic Systems: Sources, Accumulation, Environmental Impact and Mitigation Strategies

AI summary · Read the abstract

This review synthesizes how microplastics enter aquatic ecosystems, where they accumulate, and what harm they cause to wildlife and water quality — while also evaluating mitigation strategies, highlighting that both primary sources like microbeads and secondary sources like degrading plastic waste need to be addressed.
