Abstract

In order to evaluate the effect of agricultural crops, such as kenaf (Hibiscus Cannabinus L.), corn (Zea Mays), and barley (Hordeum vulgare), in the removal of Cr and Pb from soil irrigated with wastewater, an experimental pot was conducted at Green House of University of Technology. Three levels of water were used for irrigation included tap water (control) (T1), 50% of wastewater+50% of tap water (50%WW) (T2) and 100% wastewater (100%WW) (T3). The obtained results, indicated that kenaf, and barley have been an effective plant in removal of Cr and Pb due to its high removal efficiency. Maximum values of removal efficiency were recorded in August 2015 for the (100%WW) and found 85.59%, 82.77, 93.27% of Pb and 85.67, 93.85, 87.24% of Cr for corn, kenaf and barley, respectively. Minimum removal efficiencies recorded at (50%WW) treatment for Pb were (5.66, 4.48, 0.99% ) and at control treatment for Cr were ( 0.99, 1.51, 2.37%) for Cr in May 2015 for corn, kenaf and barley, respectively. From the results obtained, kenaf, and barley were effective in removal of Cr and Pb due to its high removal efficiencies.

Abstract

This study aimed to use callus cultures of Acacia trees as indicator for the validity of employing these trees in the phytoremediation programs that were used to manage the pollution with uranium in soil. Various concentrations of uranium (0.0, 50,100, 200, 500 and 1000mg.l-1) in the form of uranyl nitrate were added to MS medium that used for the initiation and growth of Acacia callus in the presence of 0.5 mg/l of each NAA and BA. For comparison, two species of Acacia were used in this study, A. albida and A. nilotica. Fresh and dry weight of callus was determined along three growth periods (30, 60 and 90 days). levels of uranium in callus cells were determined using TXRF analysis. The Results showed that fresh and dry weight of callus increased with the increase of uranium concentrations except that grown on MS with 1000 mg.l-1 of uranium in which inhibition in both fresh and dry weight of callus after three months of growth was recorded .Analysis of the cellular content of uranium using TXRF revealed that the maximum level obtained when callus grown on MS with 500mg.l-1 .

Abstract

An experiment was carried out to study cadmium tolerance at the tissue culture and whole plant levels of Helianthus annuus. Callus was initiated and maintained on Murashige and Skoog medium (MS) supplemented with 0.2 mg.L-1 Kinetin (KIN), 0.4 mg.L-1 Naphthalene acetic acid (NAA) and 0.5 mg.L-1 2,4- dichlorophenoxy acetic acid (2,4-D) using hypocotyls explants for callus induction. Different concentrations of cadmium were added directly to the culture medium as a contaminants. Selected tolerant cell lines were subjected to regeneration. The concentration of cadmium accumulated in callus tissues recorded 18 ppm at 2.0 mg.L-1 of Cd. The study included the effect of the cytokinin Benzyl adenine (BA) and the auxin NAA on the number of regenerated shoots percentage from tolerant callus to Cd. Results exhibited that 71% of callus tolerant to Cd, when the combination of 1.0 mg.L-1 BA and 0.5 mg.L-1 NAA was supplemented to the medium. The effect of NAA on rooting of shoots showed that the concentration 2.0 mg.L-1 of NAA gave rooting percentage mounted to 66%. The study also included measurement of plant height and fresh weight. Maximum Cd accumulation reached 12.2 ppm in the shoots. Tolerance to Cd seems to express in the plant shoots according to the current study.
