By Puntarenas, Costa Rica — Costa Rica’s pristine beaches and vibrant marine ecosystems are facing a hidden invasion: microplastics. A recent study by the College of Chemists of Costa Rica and the Center for Research in Marine Sciences and Limnology (CIMAR) has confirmed the presence of these tiny plastic particles in the country’s coastal waters, sands, and even within marine organisms consumed by humans.
The research, spearheaded by chemical laboratory technician Juan Guillermo Sagot, focused on the Gulf of Nicoya and the Gulf Dulce. In Puntarenas, concentrations reached a staggering 2,934 particles per square meter. The most common culprits? Synthetic fibers originating from laundry and discarded fishing nets.
To understand the legal implications of microplastic pollution, we spoke with Lic. Larry Hans Arroyo Vargas, an attorney at Bufete de Costa Rica.
The pervasive nature of microplastic pollution presents a complex legal challenge. While international treaties address marine plastic debris, the enforcement and regulation of microplastics specifically are still developing. Businesses face increasing pressure to demonstrate responsible sourcing and manufacturing practices to avoid potential liability for environmental harm, while consumers are left with limited recourse for exposure. This evolving area of law will require innovative solutions to protect both environmental and human health.

Lic. Arroyo Vargas aptly highlights the intricate legal web surrounding microplastic pollution. The lack of concrete regulations and the diffuse nature of the problem demand a collaborative effort from businesses, consumers, and lawmakers alike to navigate this emerging challenge. Innovative legal frameworks and technological advancements will be crucial in mitigating the risks posed by microplastics. We thank Lic. Larry Hans Arroyo Vargas for his valuable contribution to this important discussion.
Alarmingly, the study documented microplastics in commonly consumed seafood, including fish, shrimp, bivalves, and freshwater lobster. Many of these particles contain toxic chemicals like Bisphenol-a (BPA), linked to cancer, hormonal disruptions, and cellular toxicity.
These plastics reach the ocean through multiple channels, and the worrying part is that they return to us through the food chain. It’s no longer just an environmental concern; we’re talking about public health.

The ingestion of microplastics by marine life, including fish, turtles, mollusks, and birds, can lead to internal injuries, digestive blockages, starvation, and even death by asphyxiation. The implications for Costa Rica’s rich biodiversity are significant.
Synthetic fibers were found in 90% of the analyzed sand and water samples. Common plastic waste items like bottles, bags, packaging, and utensils contribute to the problem. Furthermore, less than 5% of plastic waste in Costa Rica is recycled, exacerbating the issue. Rivers, particularly the Tárcoles, act as conduits for vast amounts of solid waste, flowing directly into the ocean, especially during the rainy season.
The environmental consequences are already apparent. Sagot warns that if the progressive deterioration of beaches and coastal ecosystems continues, the tourism industry, a vital part of Costa Rica’s economy, could be severely compromised.
The findings underscore the urgent need for comprehensive solutions to address plastic pollution in Costa Rica. Improved waste management practices, increased recycling rates, and public awareness campaigns are crucial to mitigating the long-term effects of this invisible invasion.
