INCIDENCE OF MICRO-PLASTIC AND THEIR ACCUMULATION IN THE INTESTINE OF LIVING ORGANISMS

Greetings and welcome dear users of this prestigious platform, back with the scientific approach, this time we will be socializing the influence and incidence of the accumulation of microplastics in the intestine of living beings and how they move throughout the metabolic system.

In this sense, it is necessary to understand that a microplastic particle is considered as all those pieces of plastic that tend to pollute the environment and whose diameter is equal to 15 mm, these materials come from from various sources, although currently the products associated with cosmetics, clothing or fishing articles that derive from industrial processes, with the aim of improving the quality of life of the human species, have generalized the use of this type of materials, which have been able to reach from the outside to the inside of our intestine.

Therefore, we have to specify that any material associated with plastics are difficult to biodegrade and consequently only with the action of time and environmental conditions they disintegrate into much smaller particles, which They are the ones that end up traveling or being absorbed by living beings, staying throughout the body, including tissues, muscles and consequently when the accumulation is very high, an intoxication process is produced that in many cases can cause death. death.

Under this approach, the precise implications of the accumulation of these microplastics are still unknown, so that at the scientific level, research is being carried out to generate a methodological guide to detect and quantify the presence of these substances in the human body, on the analysis of biological samples which would give a broader and more precise vision of the risk that is run due to an overexposure of these substances on health.

Based on the above, a group of researchers associated with the Autonomous University of Barcelona have managed to detect, identify and quantify a methodological process that allows microplastics to be monitored, from the different environmental ecosystems to the interior of a living organism, so that the finding has been developed through an electron microscopy process, using as starting material the larvae of the Drosophila melanogaster fly, a species widely used in the study of biological phenomena and processes.

In this sense, the group of researchers have managed to describe the behavior of microplastics along the route to the intestine, using commercial polystyrene as a starting point, which has been simplified to manometric measurements, they have followed up on it. on a micro scale which has allowed them a kind of photographic report that allows detecting and identifying each of the stages and interactions that occur in the body of the species depending on the presence of micro plastics

Consequently, it has been possible to describe and identify the ability of this substance to first cross the intestinal barrier and its presence at the hemolymph level, which is equivalent to the behavior that it would be obtained in the blood of humans and in the hemocytes, which biologically are all those cells that correspond to our lymphocytes.

Thus, this study allows conceptual and methodological approximations to be made in order to accurately determine the degree of influence that the presence of microplastics has in the intestine, and for this they have been able to carry out this study. type of procedure by Drosophila melanogaster flies.
