Biogeochemical Cycling of Metals in Freshwater Algae from Manaus and Carajas, Brazil
Fyfe WS and Konhauser KO. 1993. Biogeochemical Cycling of Metals in Freshwater Algae from Manaus and Carajas, Brazil. Energy Sources. 15:595-608
Freshwater algac were analyzed in different riverine environments in Manaus and Carajas, Brazil. Filamcntous algae from both locations were characterized by enhanced levels of a wide array of heavy metals. A comparison of the two main rivers in the Manaus area indicated that the algal samples from thc solute-rich waters of the Rio Solimoes consistently contained higher metal concentrations than in the solute-deficient waters of the Rio Negro. A similar relationship also existed between algal samples collected from forested regions relatice to adjacent deforested regions in the Carajas area.
