    Abstract

    Ecological risk assessment was made along the Miri coast based on trace element concentrations (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Rb, Zn) in the seawater, sediments, and aquatic biota (fish, shrimp, crabs, and bivalves). Prevailing major geochemical processes were identified. Contamination and risk assessment indices were estimated. Sediments were contaminated by Cu and Zn, but in the marine life the remaining metals were within the permissible limits set by international and national guidelines.
