Quintana Roo faces record sargassum levels and health risks

Quintana Roo has reached a historic milestone in sargassum accumulation, with officials reporting that more than 105,000 tons have been removed so far this year, surpassing the previous 2025 record. Projections suggest the year-end total could reach at least 130,000 tons.

The massive influx of macroalgae is causing significant economic and health concerns. In the Riviera Maya, businesses in Tulum and Playa del Carmen have reported substantial revenue losses, and the state is implementing a multi-billion peso strategy to combat the issue. Despite these environmental challenges, tourism from Europe remains resilient, with high flight occupancy rates to Cancún.

Health risks are also mounting. Researchers from UNAM are studying the impact of hydrogen sulfide gas released during the decomposition of the algae. Workers collecting the sargassum are being exposed to levels significantly higher than safety standards, leading to skin irritation, respiratory issues, and neurological symptoms. Scientists are now expanding their studies to determine the long-term effects on local residents living near the coast. Meanwhile, some experts are exploring ways to repurpose the sargassum into biofuels and other sustainable materials.
