The pollution (Pollution is defined as what makes the environment unhealthy. The definition varies depending on…) By means of plastic affects all walks of life. Microplastics enter the marine food chains in particular, and then ascend to the largest animals andman (The man is an adult male of the type called modern man (Homo…). interactions with Plankton (Homer called the animals that wander on the surface of the waves plankton, from the Greek…) They seem particularly important, but they are still not well understood. Microalgae that make up most of the plankton and the first Link (Link in nautical language is the length of the chain (the anchor line) that measures 15…) subordinate food chain (A food chain is a chain of organisms in which everyone who eats them eats…) aquatic, may congregate under certain conditions. However, microplastics cause the formation of these aggregates, where they mix and thus transfer to animals or spread to the depths oceans (Oceans stylized Ωceans is a French documentary film directed by…). In fact, heavier aggregates sink rather than float.
Researchers from the Toulouse Institute of Biotechnology, Bio-Chemical Engineering (TBI, CNRS / INSA Toulouse / INRAE), Laboratory of Analysis andArchitectural Engineering (Architecture can be defined as the art of building construction.) Systems (LAAS-CNRS), Molecular Interactions and Laboratory for Chemical and Photoreaction (IMRCP, CNRS/University of Toulouse/Paul Sabatier) have shown that microplastics promote, in two different ways, the formation of planktonic pools to which they then bind. mix up.

Microalgae emit extracellular polymeric substances (EPS), a together (In set theory, a set intuitively identifies a set…) From the carbohydrates, proteins, and nucleic acids you use to colonize hard surfaces and cause their buildup. Co-authors and co-authors confirmed that the presence of plastic particles enhanced EPS production. This has already been observed, but the team also showed that even by completely removing the EPS, the microalgae still collected more in the presence of the microplastics. This time it is this phenomenon that is caused by direct contacts, by hydrophobic interactions between the microplastics and the cell wall. Part of the team is now studying whether micro and nanoplastics, once ingested by animals or humans, can be absorbed by the body and what consequences this can have for the body. health (Health is a state of complete physical, mental and social well-being, and is not…).
