A Study of the Environmental Characteristics of the Alhagi plant and its Ability to Withdraw Cadmium from the Soil of Baquba District - Diyala Governorate

Abstract

The current study is carried out from 01/Sep./2021 to 27/Sep./2021 in four sub-districts, which are Buhruz, Kanaan, Muhammad Sukran and Khan BaniSaad belonging to Baquba district inDiyala governorate. It is conducted by collecting three samples of Alhagi plant with its soil from agricultural and non-agricultural lands, and three compound soil samples from virgin, uncultivated lands for each site. The aim is todetect the concentration of cadmium (Cd) in both, the soil and the Alhagi plant to determine some environmental characteristics, which are the bio-concentration factor (BC), translocation factor (TF), and bioaccumulation coefficient (BAC).Where the plant plays an important role in maintaining the ecological balance by participating in the nutrient cycle, as well as providing a huge root and leaf space to repel, absorb and accumulate heavy elements. The results showed that there were significant differences between the treatments of the site, as the bioconcentration coefficient of cadmium recorded the highest average in the third site and the treatment of non-agricultural soil by 0.118 ± 0.921 and 0.084 ± 0.931, respectively. As for the transmission coefficient, the highest average was recorded in the first site and the treatment of non-agricultural soil with 0.095 ± 1.0576 and 0.067 ± 1,147, respectively. As for the bioaccumulation coefficient of cadmium, the highest average was recorded in the first site and the non-agricultural soil treatment was 0.121± 1.345 and 0.086 ± 1.030.
