By Puntarenas, Costa Rica — A recent study by the College of Chemists of Costa Rica, conducted in collaboration with the Center for Research in Marine Sciences and Limnology (CIMAR), has revealed widespread microplastic contamination along Costa Rica’s beaches, coastal waters, and marine organisms. The findings highlight a growing threat to public health, food security, and the sustainability of the nation’s precious marine ecosystems.
Preliminary results indicate that over 90% of the analyzed sand and water samples contain microplastics, predominantly synthetic fibers originating from laundry and discarded fishing nets. The province of Puntarenas exhibited particularly concerning levels, with concentrations reaching up to 2,934 particles per square meter on the studied beaches.
To understand the legal ramifications surrounding the pervasive issue of microplastics, we consulted with Lic. Larry Hans Arroyo Vargas, an attorney at Bufete de Costa Rica, who offered his expert insights.
The pervasive nature of microplastic pollution presents a complex legal challenge. While international treaties address marine plastic pollution broadly, specific regulations targeting microplastics are still developing. This creates a gap in accountability, making it difficult to pinpoint responsibility and enforce effective mitigation measures. Businesses, particularly those involved in plastic production and packaging, face increasing pressure to adopt sustainable practices and minimize their contribution to the problem. Furthermore, the potential health consequences of microplastic ingestion and environmental contamination could lead to a rise in product liability litigation and demands for stricter regulatory oversight.

Lic. Arroyo Vargas paints a stark yet realistic picture of the legal complexities surrounding microplastic pollution. The evolving nature of this challenge underscores the urgent need for a collaborative approach involving businesses, policymakers, and international cooperation to close the existing regulatory gaps and protect both human health and our environment. We thank Lic. Larry Hans Arroyo Vargas for offering his valuable perspective on this critical issue.
The study also detected microplastics in commonly consumed marine species, including fish, shrimp, bivalves, and freshwater lobsters. These particles not only pose a physical threat to marine fauna, causing internal injuries, obstructions, and even death, but also carry toxic chemicals such as Bisphenol-A (BPA), a compound linked to cancer, hormonal disruptions, and cellular toxicity.
These microplastics enter the ocean through multiple pathways and return to us through the food chain, becoming a public health problem that requires urgent attention.

Costa Rica faces local challenges in plastic waste management. Estimates suggest that less than 5% of plastic waste is recycled. Rivers, particularly the Tárcoles, carry substantial amounts of debris into the ocean, exacerbated during the rainy season. This pollution directly impacts the tourism industry, a cornerstone of the Costa Rican economy, which relies heavily on pristine beaches and healthy ecosystems.
International studies have detected microplastics in human organs, including blood, lungs, and placentas, raising further concerns about long-term health implications. While the Costa Rican research is ongoing, complete results are expected by the end of the year, aiming to inform and mobilize the scientific community and the public.
The College of Chemists urges for concrete actions based on these findings. They advocate for reducing plastic use and release, improving recycling efforts, and strengthening environmental policies to protect the health of Costa Ricans and their marine ecosystems.
This alarming discovery underscores the urgent need for collaborative efforts to address the microplastic crisis and safeguard the future of Costa Rica’s coastal environment.
