The objective of this research is to evaluate the contamination level of copper (Cu), lead (Pb) and zinc (Zn) in the sediments collected from Bang Yai Canal, Phuket province. Surface sediment samples were collected with Petersen Grab from 14 sampling points, prepared by geochemical methods, and then measured by using inductively coupled plasma optical emission spectrometer (ICP-OES). The results showed that Cu and Zn were exceeded the sediment quality standards (SQGs), especially from the sampling points in the middle and the end of Bang Yai Canal. The degree of pollution level in sediments assessed by Geo-accumulation index (Igeo) indicated either not contaminated Cu or moderately contaminated with Pb and Zn at some point in the middle to the end of the Bang Yai canal. This is consistent with the development of the tin mining industry of Phuket in the past and from human activities along Bang Yai Canal. However, the contamination level is still acceptable.
