Although Brassica juncea (Indian mustard) is reported to be a good accumulator of metals, little is known of the selected varieties of B. juncea (cvs. Rai and BARI-11). This paper investigates the phytoaccumulation of arsenic, cadmium and lead by B. juncea (cvs. Rai and BARI-11) parents and F1 hybrids. The experiment was conducted in the hydroponic media in the greenhouse of University of Southampton under a Randomised Block Design. Sodium arsenite, cadmium sulphate and lead nitrate with 0 ppm, 0.5 ppm and 1 ppm were used. The cadmium treated plants were analysed by Varian Atomic absorption spectrophotometer-200. The samples of arsenic and lead were analysed by Inductively Coupled Plasma Atomic Emission Spectrophotometer. The results suggest that arsenic was detected only in the root systems while cadmium and lead were detected both in the root and shoot systems. Significant differences in the uptake were observed for different concentrations. Accumulation of arsenic was detected only in the root systems of B. juncea (cvs. Rai and BARI-11) at lower concentrations. Hence, this can be used as an agriculturally viable and efficient phytoaccumulator in the arsenic affected areas where contamination level is low and the contamination occurs at the rooting level.

“…Pb concentration in root was higher than upper side of the plant tissue (shoot and leaf) for all treatments. This trend was also found on the several studies of Pb phytoremediation by Potamogeton natans (Fritioff and Greger, 2006), Siam weed Chromolaena odorata (L.) King & Robinson (Tanhan et al, 2007), Phragmites australis (Baldantoni et al, 2009), Brassica juncea (Liu et al, 2000;Meyers et al, 2008). For treatment 30 and 50 mg/L, Pb concentrations in roots were found to reach level indicative hyperaccumulation, which the concentration are >1000 mg/kg for Pb, compared to a study done by Haque, et al, (2008).…”

A pilot reed bed study was conducted with the aid of aeration to remove lead (Pb) contaminated water using Scirpus grossus L. f. The plants were grown in sand medium in pilot-scale reed beds, and exposed to water containing Pb in a various concentration (10, 30 and 50 mg/L) with aeration rate of 2 L/min. The samples were taken on day-1, day-14, day-28, day-42, day-70 and day-98. The results showed that Pb concentration in water decreased 74% on day-7, 80% on day-14, 99% on day-28 and reach 100% on day-48 for treatment 10 mg/L. Pb concentration decreased 91% on day-7, 93% on day-14 and then on the day-28 the reduction reached 99% for treatment of 30 mg/L. For Pb treatment of 50 mg/L, the reduction reached 92% on day-7, 96% on day-14, and 99% on day-28. The sand adsorbed Pb up to 7.91×10 -4 mg/kg for 10 mg/L, 1.07×10 -3 mg/kg for 30 mg/L and 2.41×10 -3 mg/kg for 50 mg/L. Pb uptake by plant was 2286 mg/kg on day-98, 4174 mg/L on day-28

“…Apparently, radish is more tolerant to Pb on an equimolar basis compared to Brassica. juncea (Liu et al, 2000) and Allium cepa (Liu et al, 1994). Gopal and Rizvi (2008) were showed that excess Pb reduce the fresh and dry weight in leaves of radish at 30 day (0.5 mM).…”

Oxidative Stress Induction by Lead in Leaves of Radish (Raphanus sativus) Seedlings

et al. 2011

Oxidative stress was induced by lead acetate (Pb) in Raphanus sativus seedlings grown in a hydroponic system using sand as substrate. Thirty day old acclimated seeds were treated for 7 days with five Pb levels (0 as control, 100, 200, 500 and 1000 mg l -1 ). Parameters such as growth, oxidative damage markers (lipid peroxidation, protein oxidation and hydrogen peroxide contents) and enzymatic activities of catalase (CAT) and peroxidase (POD) were investigated. Lead concentration in plant tissues increased with increasing of Pb levels. Shoot fresh weight, chlorophyll and carotenoid concentration were significantly decreased at 100 mg l -1 Pb. Lipid peroxidation, protein oxidation and H 2 O 2 levels were increased at 500 and 1000 mg l -1 Pb compared to control treatment, in shoots. Peroxidase activity showed a straight correlation with H 2 O 2 concentration, whereas CAT activity decreased only in shoots. These changes in enzymatic and non-enzymatic antioxidants showed that the Pb exposition had a significant disturbance on Raphanus sativus plantlets and affect the biochemical and physiological processes.
