• Description:
  Rare earth elements (REEs) are a group of chemicals widely used in emerging technologies today, and are often labeled as potential environmental contaminants. The Cayos Cochinos Archipelago is a protected area of Honduras, Central America, with intertidal and supratidal sands, making it a prime candidate for pollution research. In December 2022, sand samples from the Cayos Cochinos area was collected and analyzed by X-ray fluorescence to determine the levels of REEs and some less-studied trace elements (TEs). Based on the findings, REEs mean contents (µg g-1 d.w.) fluctuated between 2.96 for Y to 667.1 for Nd, while TEs ranged from 10.37 for Th to 3896.2 for Sr. Also, the results showed significantly higher levels of La, Pr, Y, Sr, Ba, and Th in the supratidal zone than in the intertidal zone. The data are useful as a basis for understanding the presence of chemical elements in near-shore marine areas and subsequently help identify sustainable practices that will reduce the impacts of these chemicals.
