Presence of microplastics on six beaches in the department of La Libertad, 2022
AI summary Read the abstract
Researchers collected and analyzed microplastics on six beaches in La Libertad, Peru, finding plastic particles in both the upper beach and lower intertidal zones. The study contributes baseline data on microplastic contamination along Peru's Pacific coastline.
The presence of plastic on the beaches has generated that over time they degrade into particles of 5 to 1 mm, known as microplastics, in fact, being of micro size they can be ingested by different organisms, causing a highly worrying panorama for life. Therefore, the objective was to determine the significant difference in the presence of microplastics in quantity and weight in supralitoral and litoral zone of six beaches in La Libertad. For this, a quantitative approach was used and the type of research was descriptive, applied, cross-sectional, prospective, observational and non-experimental, the method used was inductive -deductive through ANOVA Statgraphics and Minitab, the technique was data collection and the. The instruments were the data collection sheets and the observation guides. According to the results with a significance level of 5%, the effect of the beach factor, the effect of the Zone (litoral and supralittoral) and the interaction of both effects are significant for the factorial model, since all the p-values (0.000) are less than 5. %, so it is concluded by stating that there are significant differences in the quantity and weight of microplastics found on the 6 beaches.

Researchers estimated the abundance, characteristics, and types of microplastics on three beaches along the northern tourist corridor of Piura, Peru, characterising the size, colour, and polymer types of particles found in beach sediments to assess contamination levels in this coastal region.
Small plastic debris along the coast of Peru
AI summary Read the abstract
Small plastic debris including meso- and microplastics were surveyed along Peru's coastline, finding contamination at all sampled sites with significant variability by season and location. Higher concentrations were found near urban centers and river mouths, reflecting poor solid waste management and land-based inputs. The study provides the most comprehensive baseline data yet for plastic pollution along the Peruvian coast.
