Mercury (Hg), Lead (Pb), Iron (Fe), Copper (Cu), and Arsenic (As) were measured in Puerto Mosquito (Vieques) and La Parguera (Lajas) bays. These are the two most well-known bioluminescence bays of Puerto Rico. The samplings were carried out by Yadira Soto and William Hernandez as part of the research activities in a project sponsored by Sea Grant. This was also the undergraduate research project of Yadira, whom presented it at the end of the semester to the faculty of the Geology Department as part of her requirements in that curse.
