Abstract
Background and Purpose: Distribution of heavy metals in all types of sediments is one of the important and new topics in environmental sedimentology. This study was conducted with the aim of investigating the amount of factor pollution, concentration of cadmium and lead metals, geochemical accumulation index and ecological risk category in the soil downstream of Taibad Landfill.

materials and methods: 15 stations were selected at a distance of 100 meters from each other and along the waterway exiting the site from a distance of 100 to 1500 meters. After sampling 5 samples and repeating 3 times from each station, the samples were taken to the laboratory for analysis.

Results: In stations 2 and 6, because the pollution factors (CF) are between 1 and 3, the level of pollution in these stations is average, in station 10 it is very high, and for the rest of the stations, because the pollution factors are between 3 and 6, the level of pollution is high. For cadmium metal, the pollution factor (CF) in all stations is between 3 and 6 and the pollution is high. Based on the results, the amount of lead and cadmium metals in the risk category They are ecologically average.

Conclusion: The amount of lead metal pollution in station 2 and 6 is moderate, station 3 is very high and in other stations it is high. Cadmium metal contamination was reported in all stations. Both metals are in the medium category in terms of ecological risk.

The concentration mentioned metals in the soil downstream of the landfill is significantly higher than the global soil average and the earth's crust. It seems that this pollution is caused by the landfill, which was spread to the downstream lands by seasonal runoff
