Study of Contamination of Some Plants With Some Heavy Metals and Study The Presence of Cyanide in Plants in The City of Mosul

Abstract

Abstract The research included a study on the presence of some heavy metals, including copper, iron and zinc in some medicinal plants circulating in the city of Mosul, as well as the study of the presence of cyanide in some other plants, when measuring the concentration of iron in saffron was less concentrated among plants of 0.797 mg/kg, followed by anise 7.3417 mg/kg, followed by mint 10.87 mg/kg. Kg and high concentrations appeared in the coriander plant, where the iron concentration was 486.6 mg/kg, ginger bread 396.49 mg/kg and corn 200.1 mg/kg and Marjoram 154.2 mg/kg, either Measuring the concentration of potters in medicinal plants in saffron plant was the lowest concentration of all plants used in the study and was 0.304 mg/kg followed by anise 7.8 mg/kg, followed by oranges 17.58 mg/kg, and high concentrations of coriander 179.2 mg/kg, ginger 111.3 mg/kg, while measuring of the concentration of copper in the medicinal plants used in the study the ratio of copper in saffron was low and amounted to 0.377 mg/kg (Dry weight), the highest concentration of copper was in the coriander plant, which was 120.922 mg/kg, ginger copper concentration was 50.78 mg/kg, and for the rest of the plants the concentration of copper ranged from (2.93 to 36.1) 22 mg/kg), while when measuring the iron ratio in the medicinal plants used in the study, and in a study The concentration of cyanide in plants (diphtheloide, apple seeds, perfalathseeds, henna seeds, castor seeds) by Spectrophotometer has been obtained different cyanide concentrations in these plants in the diphtherty the highest ratio of cyanide is 71.4 micrograms/30g (dry weight) followed by castor seeds 64.05 micrograms/30g, followed by henna seeds 31.36 mcg/30g, while in apple seeds the concentration of cyanide was 29.6 μg/30g and orange seeds 10.95 mcg/30g.
