Abstract
Trace metal levels in bottom sediments of Laguna Lake (Luzon, Philippines) and of five of its tributary rivers, and in lakeshore samples were compared. Total metal analyses by flame atomic absorption spectrophotometry indicate relatively low (Cu, Zn, and Pb) to moderate (Fe, Mn, Hg, and Cd) metal contamination in the sediments.Keywords
