The Relationship between the Absorption of Heavy Metals of Mercury and the Amount of Chlorophyll and Sugar Production in the Plane Tree Species Seedlings
Message:
Abstract:
Background and Objective

The groups of harmful factors in the ecosystem are heavy metalsn which are particularly important due to their lack of absorption and physiological effects at low concentration on living organisms.

Method

In this research, the ability of plant tree species to absorb heavy metal mercury was investigated. Two-year-old seedlings of plane tree species were prepared from nursery. Zero and 100 mg / L concentrations of mercuric chloride solution were added to the seedlings' potting soil. After six months, the shoot and root were isolated from the growth of the seedlings, then the concentration of mercury metal was determined in samples and then the data were analyzed.

Findings

The results of data analysis showed that the highest amount of mercury accumulation in the shoot was 64.95 mg / kg at the root was117.94 mg / kg and in the soil were 21.33 mg / kg and the total chlorophyll content and sugar content were 4.66 mg / g and 0.552 mg / g, respectively.
Discussion and

Conclusion

Based on the results of this study, plane tree species is relatively suitable for purification of contaminated soils from mercury metal.
