Investigation distribution of heavy metals contamination (As ,Co,Ni,Pb) in sediments in Dohezarriver(Iran- Tonekabon) and interpolation pollution using kriging model in GIS

In this study, concentrations of heavy metals arsenic, cobalt, nickel and lead in samples of sedimentin 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 surfacesediments show a similar distribution to the rest of the elements.GIS software interpolation toestimate the male and Pollution discussed
