Mikroplasty v mořských plodech a jejich dopad na lidské zdraví
AI summary Read the abstract
This study investigated the ingestion of microplastics by commercially harvested oysters and the effect of depuration on particle clearance, finding that standard depuration protocols did not fully eliminate microplastics from oyster tissues. Particles retained in gill and mantle tissues after depuration may still be present in oysters sold for human consumption.
This bachelor thesis summarizes current knowledge regarding the accumulation of microplastic particles in the marine fauna and their impact on marine organisms. The uptake of microplastics has been demonstrated in laboratory and natural conditions in various marine organisms, including zooplankton, oysters, mussels, and shrimp. Microplastic particles are transferred from lower to higher taxonomic levels through the food chain via trophic transfer. The model transport within the food web was studied in a marine crab that was fed with mussels contaminated with microplastics. Microplastic fragments were able to penetrate from the crab's gastrointestinal tract into surrounding tissues. Microplastics are receiving a lot of attention in research as potential carriers of dangerous chemicals. The consequences of microplastic contamination on the food chain and human health are not sufficiently explored and require further study.

Microplastics in coastal and marine environments: A critical issue of plastic pollution on marine organisms, seafood contaminations, and human health implications
AI summary Read the abstract
This review highlights the serious threat microplastics pose to marine life and the millions of people who depend on seafood as a primary protein source. Marine organisms, especially filter-feeders like oysters and mussels, accumulate microplastics that can cause tissue damage, oxidative stress, immune changes, and behavioral problems. Since these shellfish are often eaten raw, any toxins they accumulate -- including microplastics -- pass directly to humans.

AI summary Read the abstract
This Czech bachelor's thesis reviewed current knowledge on microplastic sources, environmental distribution, and effects on animal organisms. Ingestion was identified as the most common interaction pathway, leading to tissue damage, reproductive problems, and particle accumulation, with the review also covering monitoring approaches and strategies to limit environmental and human health impacts.
Trophic and direct transfer of Microplastics into the common shore crab Carcinus maenas
AI summary Read the abstract
Laboratory experiments examined microplastic bioaccumulation and trophic transfer of 10 um fluorescent polystyrene microspheres using mussels (Mytilus edulis) and shore crabs (Carcinus maenas). Microplastics transferred from mussels to crabs through trophic pathways, demonstrating for the first time that microplastics can move up marine food chains.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
AI summary Read the abstract
This review examines how microplastics and the chemicals they carry transfer through marine food webs from lower to higher trophic levels, and what this means for human health given that people consume marine fish and seafood. It identifies microplastics as a vector for bioaccumulation of persistent organic pollutants in ways that ultimately reach humans.
Microplastics as contaminants in commercially important seafood species
AI summary Read the abstract
This review summarizes evidence that microplastic ingestion is widespread in commercially important seafood species including mollusks, crustaceans, and fish. Evidence indicates that microplastics can affect physiology, reproductive success, and survival in marine organisms, and may also act as vectors for chemical pollutants. The study highlights the potential for human exposure to microplastics through seafood consumption, though the full health implications remain to be determined.
