MARTINEZ GONZALEZ, Valeria Susana et al. The issue of micro and nanoplastics on the American coasts of the Pacific Ocean. Mundo nano [online]. 2023, vol.16, n.30, e00067.  Epub 14-Ago-2023. ISSN 2448-5691.  https://doi.org/10.22201/ceiich.24485691e.2023.30.69783.

This work addresses the micro and nanoplastics (MP and NP, respectively) on the American coasts of the Pacific Ocean from the perspective of the Micro & Nano Allpa Pacha Network. This network is made up of scientists from Chile, Perú, Costa Rica, Colombia, Ecuador, Panama, and Mexico, who, concerned about the impact on the environment and its repercussions on health, decided to establish international scientific collaborations for the geolocation, monitoring, and characterization of MP and NP present on the coasts of the Pacific Ocean in the American continent. It is expected to provide data based on harmonized scientific evidence, which will impact the teaching and planning of control and regulation measures for these pollutants in our countries. This work includes some aspects of polymers and plastics, definitions of MP’s and NP’s and their various impacts, the problem of taking samples, adequate characterization, among others. One of the conclusions determined that are many characteristics of NP’s and MP’s without investigating, such as interaction with other chemical products, the impact of morphology on bioavailability, formation of adhesions and their release during their contact with environmental compartments, the dependence of its composition with its behavior and destiny, among others. Likewise, it was determined that any contribution to mitigating the problem of these materials must include awareness, prevention, and reduction through a comprehensive approach to education and training and considering all actors in society responsible for the problem generated under a scientific evidence approach. Finally, it was determined that the issue is still in its initial phase, and the information is repetitive and self-referenced.
