Efecto de los microplásticos de poliestireno sobre el citoesqueleto de células humanas

Abstract

Plastic has become very popular in recent years due to its durability and properties. Despite its many advantages, humanity has developed a certain dependence on this material, which represents an increase in its use and in turn, in waste. One of the most widely used plastic polymers is the polystyrene (PS), as is used in a wide range of applications due to its low cost and easy production, although after the useful life of the plastic, it is considered as waste. When plastic is exposure to atmospheric conditions such as UV radiation, it degrades and fragments giving rise to microplastics (MPs), which are defined as small particles that do not exceed 5 mm, representing a threat to the environment because when they degrade the properties decay, a dimensional change is generated, and they can also be easily transported not only to the environment but also to organisms. This review article focuses on highlighting the main pathways that MPs follow when interacting with humans and the potential effects of PS-MPs on the cytoskeleton, as well as highlighting the need for more studies in this regard. Key words: Cells; cell-plastic contact; emerging pollutants; polymers; microplastics.
