Assessing Fe and Zn content in Egeria densa: Sample treatment influences significantly the quantification of metals in Egeria densa

Abstract Wetlands are fragile ecosystems that support diverse habitats and are under constant environmental pressure. The "Carlos Anwandter" Ramsar Site located in Valdivia, Chile, is home to many waterfowl species, and it is the main reproductive site for black-necked swan in the world. The main food source for these
