Land-based sources are considered the most important source of microplastic pollution to marine environment. Stormwater runoff has been identified as one of the main pollutant contributors to water bodies. Seven sites were sampled to identify and quantify microplastics in stormwater runoff in Tijuana, Mexico.

Twenty-one sandy beach sites were sampled to investigate the occurrence and distribution of microplastics on the sandy beaches of the Baja California Peninsula, Mexico, as well as their spectroscopic characterization and morphology. Microplastics were separated using the density method and identified using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR-FTIR).

- The study details a method for creating multi-walled carbon nanotubes (MWCNTs) with hydroxymethylene groups, synthesized using spray pyrolysis with toluene and ferrocene.
- Hydroxymethylation was performed using varying amounts of benzoyl peroxide, with 300 mg found to be the most effective quantity.
- The functionalized MWCNTs were analyzed using techniques like FT-IR, Raman Spectroscopy, and TEM, confirming that the process preserved the structure of the nanotubes.
