Abstract :
In this study, concentrations of heavy metals arsenic, cobalt, nickel and lead in samples of sediment in the river dohezar tonekabonhas been paid. concentration changes as follows: Arsenic: 4 / 10_66 / 70, Cobalt: 5 / 40_29 / 80, nickel: 12_80 and lead: 9 / 10_66 / 40 (ppm). The distribution of these four elements other than arsenic that the significant increase in surface sediments show a similar distribution to the rest of the elements.GIS software interpolation to estimate the male and Pollution discussed.
