Background:
Microplastics are considered an emerging contaminant due to their wide distribution and production in the environment, representing constant exposure to humans. However, little is known about the effects it can trigger in the body.
Objective:
To establish a concrete relationship between microplastics and the human body, their means of production, exposure, systemic responses, and diseases caused by their presence
Methods:
In this context, a review article of foreign and national literature was developed, through the PubMed and Scielo Indexers, where studies were found that address the production of plastic, the paths that lead to the production of microplastics and the exposure and damage that it represents to human health, being possible to exclude the literary sums with a publication date before 2017
Results:
hey showed that translocation of the residues occurs to the circulatory and lymphatic system via the respiratory and gastrointestinal tracts. Once in the body, microplastic can stimulate a chronic inflammatory response that functions as a precursor to neoplasia and fibrosis, or carry toxic compounds such as heavy metals, endogenous disruptors, biofilms, and persistent organic pollutants. In addition, lung biopsies have shown plastic fibers in patients with respiratory diseases, highlighting a potentially dangerous accumulation.
Conclusion:
The present moment demonstrates that experimental research to prove the effect of microplastics is extremely necessary, since the controversy among authors and the repetition of information already described affirm that the research done so far is not sufficient.
