Abstract
The concentrations of B, Ca, Co, Cu, Fe, K, Mg, Mn, Na, P, Zn and agar were determined in samples of the red alga,Pterocladia capillacea, collected during one year in three distinct locations having different hydrologic characteristics, close to the city of Arraial do Cabo, Rio de Janeiro, Brazil. Pattern recognition methods showed that, although these concentrations are subject to temporal variations, they are more dependent on the location from which the samples were collected. Algae from locations with high human activity were richer in P, B, Co, Zn and agar than those from other locations.
