“…The research was conducted off the coast of Lima region. This city is the most populated in Peru, strongly influenced by beachgoers and solid waste marine pollution (18). It is also ground to small scale artisanal fishing activity and a wastewater treatment plant (WWTP) discharge point.…”

Microplastics (< 5 mm) are widespread within the marine environment, posing a major threat to marine biota. The aim of the present study was to investigate microplastic contamination in three widespread and highly commercial fish from the coast of Lima, Peru. Peruvian silverside (Odontesthes regia), Peruvian morwong (Cheilodactylus variegatus), and Peruvian grunt (Anisotremus scapularis) specimens were caught off the coast of Lima. Fish stomach and intestines were extracted and submerged in 10% (w/v) KOH, followed by 24 h incubation at 60 °C. The resulting supernatant solution was vacuum filtrated and filters were then observed under an optical microscope and stereomicroscope. Strict quality control and external contamination prevention measures were taken. Microplastic abundance, type and color were recorded. Quality control measures resulted in reduced external contamination. C. variegatus was the most contaminated fish (5.13 ± 0.81 MP/individual), similar to A. scapularis (5.00 ± 0.46 MP/individual), but significantly different to O. regia (0.43 ± 0.11 MP/individual). Fibers were the overall most abundant microplastic type, while blue the dominant color. Results indicated highly contaminated fish, compared to those from other parts of the SE Pacific. Microplastic ingestion by C. variegatus and A. scapularis may be subject to trophic transfer from their natural prey. Highly populated cities and poor solid waste management may contribute to worsen microplastic ingestion by native marine species. The need for further research and a marine microplastic monitoring program was discussed.

Objective: The objective of this study was to quantify the inorganic waste of the Atascoso estuary as a mitigation strategy. Theoretical Framework: This topic presents the main concepts and theories that support the research. Highlighting the diagnosis of the current situation and dynamics of inorganic waste generation, also the quantification of inorganic waste, and for the design of a comprehensive management plan for inorganic waste using mitigation strategies; providing a solid foundation for understanding the context of the research. Method: The methodology adopted for this research includes diagnosing the current situation and generation dynamics of inorganic waste, also to quantify inorganic waste, and methodology to design a comprehensive management plan for inorganic waste using mitigation strategies. Results and Discussion: The results obtained revealed the critical situation of the estuary is due to the increase in the accumulation of garbage and the lack of environmental awareness. Therefore, it is essential that the population and the authorities act immediately to promote sustainable and responsible habits in the community. In the discussion section, these results are contextualized in light of the theoretical framework, highlighting the implications and relationships identified. This section also considers possible discrepancies and limitations of the study. Originality/Value: This study contributes to the literature through specific applicability, for a given area. The relevance and value of this research is evident in the use of mitigation strategies to promote sustainable and responsible habits in the community.
