Microplastic pollution and its impacts on marine life and human health: a literature review
Summary
This literature review summarized how microplastics are generated from larger plastic debris and the physical and toxic harms they cause to marine organisms and humans. In humans, particles smaller than 20 micrometers can penetrate cell membranes and potentially reach internal organs.
Microplastics are fragments up to 5mm in size that are polluting the oceans due to anthropic action, impacting the lives of marines and humans.The aim of this article is to inform how microplastics are generated and what are the impacts they cause to organisms.A review was carried out through works available in the databases available on the Internet.Microplastics cause negative physical effects, preventing the absorption of nutrients, due to the accumulation of these particles in the organs of the digestive system of marine organisms.In humans, particles smaller than 20μm are likely to penetrate the organs.Even smaller particles are able to move through cell membranes, blood brain barriers and placenta.Therefore, the awareness of the population through environmental education is still the main alternative for habits to be modified, and thus improve the quality of survival of planet Earth.

Impacts of Microplastics on Marine Organisms and in Human Health
This review examines the impacts of microplastics on marine ecosystems and human health, covering ingestion by marine organisms across all trophic levels, from plankton to large mammals. The authors also review the human health risks associated with microplastics detected in food, water, and air. The review calls for urgent global action to reduce plastic production and improve waste management before contamination becomes irreversible.
Impacts of microplastics on marine organisms: Present perspectives and the way forward
Researchers reviewed how microplastics — small plastic particles less than 5 mm — affect marine life from microscopic phytoplankton all the way up to marine mammals and humans, finding documented harms across nearly every level of ocean life. The review calls for urgent research into environmentally realistic exposure levels and stronger policies to reduce single-use plastic production.
Nano-Scale Plastic Pollution in the Marine Species: A Review
This review summarizes research on nano-scale plastic pollution in marine species, covering how nanoplastics are produced from larger plastics, how they enter organisms, and the toxic effects they cause in marine life. Because of their tiny size, nanoplastics can penetrate cells and tissues that larger microplastics cannot reach.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
Research progress on occurrence characteristic and toxicity of microplastics in marine organisms
This review summarizes how microplastics are ingested, distributed, and cause harm in a wide range of marine organisms, including fish, invertebrates, and seabirds. The accumulation of microplastics in marine food webs is directly relevant to human health, as these particles can reach humans through seafood consumption.
