The main objective of this study is to trace the heavy metal leached from a hybrid blocks developed in this study. The hybrid blocks produced in this study was in the form of interlocking blocks produced from high volume of palm oil waste. Palm oil clinker (POC), palm oil fuel ash (POFA), palm oil clinker powder (POC), quarry dust (QD) mixed all with cement. Leach ability of the heavy metal like Aluminum, Iron, Manganese, Zinc, Cadmium, Cobalt, Cupper, and Lead were assessed using the De-ionized water leaching procedure (DWLP) the more appropriate for in situ condition. Traces for heavy metals were analyzed using Inductively coupled plasma Optical emission spectrometer (ICP-OES). Results demonstrated that the concentrations of heavy metal leached from the blocks produced in this study were within the acceptable limits according to the Malaysian Standards. It was observed that the leaching of heavy metal was increased with the increase of palm oil clinker and decrease with the increase of quarry dust. It was concluded that the blocks developed in this study was safety for the environment and doesn’t possess any threat to the surroundings.
