Abstract

In order to investigate the concentrations of Heavy Metals in Stream sediments of the Baycheh-Bagh area, northwest of Zanjan.province, 131 samples were collected from intended stations. These samples after dissolution by four acid method, were analyzed by ICP-OES. To determine the type of Spatial Distribution of data, two important spatial statistics, i. e. global Moran’ s I and Anselin local Moran’ s I were employed. The average concentrations of As, Bi, Cd, Ni, Pb, Sb and Cu in stream sediment samples were 21. 83, 0. 32, 0. 35, 35. 57, 68. 96, 37. 67, 1. 96 and 82. 71 ppm, respectively which are higher than the average of crust whereas the average concentration of Co is 20. 30 ppm. The obtained results indicate that the Heavy Metals in the study area has a spatial structure and distributed in cluster form. According to the Local Moran’ s I results, the most contaminated area in the study area was detected in western part of the Baycheh-Bagh abounded mine and located on the present polymetallic vein-veinlet mineralizations and their related alterations. Analysis of obtained data and investigation of their relationship with the geological rock units of the study area show that concentration of the studied elements have geogenic source and is related to the mineralizations and alterations.
