Detecting zinc absorption in contaminated soils with tree species

Phytoremediation is the technology of using plants for decontamination of heavy metals and their accumulation in the different tissues and organs of plants. The contamination resulting from heavy metals is of great significance due to its sustainability in the environment. The absorption of zinc in contaminated soils was studied using one-year Arizona cypress seedlings, which were placed in vases. After the passage of each 55-day time period from the growth of the seedlings, the shoots (leaves and stem), roots and soil of the seedlings were sampled. Results were studied using an analysis of variance (ANOVA) test and Duncan's test. The highest mg/l concentration rate of zinc in Arizona cypress organs in the first time period in the shoots, roots and soil was 61.67 mg/kg, 60.1 mg/kg and 12.45 mg/kg, respectively and in the second time period in the shoots, roots and soil was 142.86 mg/kg, 85.94 mg/kg and 12 mg/kg, respectively. Based on the research, Arizona cypress is appropriate for refining zinc metal polluted soils.
