Heavy Metals in Rivers and Sediments from Two Southwestern States of Nigeria

Anthropogenic sources of heavy metals to coastal cities and their environment are mostly through the various water bodies. This study aimed at using the Potential Ecological Risk (PER) index to characterize rivers and sediments for possible environmental impact.
