Our mine polluted our plants, our animals and our lives. The people of Mahd Althahaah are deeply concerned about the dangerous consequences of mine activities in the area. The researchers examined 4 soil samples from the area they selected and 7 samples for both Rabalah and Huwaymdah. Three samples of each plant were washed with pure water. This process is intended to find out the effect of the dust from the mine. The samples were then crushed and digested in a 3051 microware. After adding some acids to the samples, they were treated by ICP to get the results.
The results show that the two plants examined are polluted with the following heavy metals ( cd,cu, pb, and zn). The concentrations of cd and pb in the unwashed Rablah samples were 2g/kg and 17g/kg respectively in contrast with 1.1g/kg and 8g/kg in the washed ones. In Huwaymdah, the concentrations were 0.7g/kg and 6g/kg on cd and pb respectively for both the washed and unwashed samples. This negatively affects the shape of the plants and its ability to receive dust. The results of the experiment show that the two plants are polluted with heavy metals. In light of this, the researchers recommend stopping any mine facilities that produce heavy metals, avoiding grazing in the areas neighboring the mine, and examining the livestock in the area to find and how they are affected by this pollution.
