        The aim of this study was to investigate the emission of heavy metals (cadmium and lead) in the soil around Taybad landfill. For this purpose, 15 stations at a distance of 100 meters from each other to the landfill of Taybad city were selected for sampling. Sampling 5 samples and repeating 3 times from each station, the samples were transferred to the laboratory for analysis to check the level of pollution indicators. Hypotheses were analyzed using one-sample t-test and Pearson's correlation coefficient with spss 24 software. It was found that the average total concentration of lead is equal to 52.04 and the average total concentration of cadmium is equal to 1.748. The concentration of the mentioned metals is significantly higher than the average global soil and earth's crust with 95% confidence. In the case of lead and cadmium, the highest contamination was in station 10 and 4, and the lowest contamination was in station 6 and 12, respectively. It is concluded that the amount of soil contamination does not change significantly with increasing distance, because the volume and concentration of contaminant runoff from the landfill (contaminant) along the path is constant. Therefore, it is better to provide environmental training for municipal municipal personnel and citizens of the region and to invest in the restoration of the environment and its further protection.

        2 - Geochemical and environmental assessment of cadmium in rhizosphere soil and leaves of 11 grape varieties in greenhouse conditions

        Cadmium is a toxic metal that has significantly increased its entry into the soil and food chain with the rise of environmental pollution. In this study, 11 grapevine cultivars (Vitis vinifera L.) were exposed to three levels of cadmium (0, 50, and 100 milligrams per kilogram) in a factorial experimental design based on a completely randomized design in the research greenhouse of Malayer University. After applying the different cadmium treatments over a period of approximately 4 months, leaf and rhizosphere soil samples of different grapevine cultivars were collected, and the concentrations of cadmium and zinc were measured using an atomic absorption spectrometer. Significant differences were observed among grapevine cultivars in terms of cadmium and zinc content in leaves and rhizosphere soil. The cultivar "Bidaneh Sefid" had the lowest cadmium content in leaves, while the highest cadmium content in rhizosphere soil was observed in the cultivar "Rish Baba." Moreover, the cultivar "Turkmen 4" had the highest zinc content in leaves, and the cultivar "Rish Baba" had the highest zinc content in rhizosphere soil. Geochemical indices including Igeo, Ipoll, CF, and BAC were evaluated in the surface soil compared to the standard shell and earthworm. Based on the results of this study, in the examination of soil indices in different grapevine cultivars and the impact of different cultivars, according to the Ipoll and Igeo (Müller) indices in the shell, in non-stressed soil without cadmium, it was considered slightly contaminated, and according to the standard shell in the earthworm, it was considered quantitatively contaminated. According to the Igeo index in the shell, in soil under 50 milligrams per kilogram of cadmium stress, it was considered slightly contaminated, and according to the Ipoll index, it was considered slightly to moderately contaminated, and according to the standard shell in the earthworm, it was considered heavily contaminated. According to the Igeo and Ipoll indices in the shell, the results of soil under 100 milligrams per kilogram of cadmium stress, were considered heavily contaminated, and according to the standard shell in the earthworm, it was considered severely contaminated. The results of these indices indicated that zinc was in the non-contaminated category. Manuscript profile
