No study have existed on heavy metals present in the river of Iloilo Batiano, Philippines. Thus, this study was conducted to determine the presence and quantities of heavy metals specifically cadmium, chromium and lead in the sediments of Iloilo Batiano River. Furthermore, water physicochemical parameters were determined such as pH and temperature, in situ. Three sampling stations were identified adjacent to (1) Batiano Bridge of Oton, Iloilo; (2) Sto. Niño Bridge of Villa, Iloilo City and (3)

Three (two sides and at the center perpendicular to the river) 500 g surface sediments were collected in each of the sampling station for a total of nine sediment samples stored in a sterile ziplock and were immediately transported at the CAS-ASL of UPV, Miag-ao, Iloilo for the quantification of metals through flame atomic absorption spectrophotometry (FAAS). Available cadmium was below detection limit and it appeared that available Pb > Cr in the three points of the river in the three sampling stations. Available chromium and lead have high accumulation in station three (Calumpang Bridge). This study provides information on the heavy metal status of the river, awareness to the public and for further conservation of the river.
