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 South...

In this work, we present the synthesis and characterization of CdS nanoparticles suitable for semiconductor applications using a simple and manufacturable process. The solution based process was synthetized at room temperature using cadmium nitrate tetrahydrate (Cd (NO3)2 .4 H2O 0.1 M) and a Thioacetamide (C2H5NS (TA) 0.5 M) as source of cadmium and sulfur, respectively. The effect of the conce...

Lead and cadmium accumulation examined in shoot and leaf tissues of seedlings of mustard (Brassica juncea cv RH-30), at 7th day, treated with either putrescine (1 mM), or ammonium nitrate (10 mM) or IAA (10 microM). These were included in the nutrient medium, containing Pb or Cd (0.1 mM and 2 mM). Metal accumulation was more in shoot than in leaf tissues, which was increased manifold under sali...

Self-assembly of proteins and inorganic nanoparticles into terminal assemblies makes possible a large family of uniformly sized hybrid colloids. These particles can be compared in terms of utility, versatility and multifunctionality to other known types of terminal assemblies. They are simple to make and offer theoretical tools for designing their structure and function. To demonstrate such ass...

The Schiff base 6-meth-oxy-2-[(4-methyl-phen-yl)imino-meth-yl]-phenol (HL) forms a neutral complex with cadmium(II) nitrate, [Cd(NO(3))(2)(C(15)H(15)NO(2))(2)], in which the four O atoms of the two independent ligands are coordinated to the metal center and the protonated imine N atoms are involved in a hydrogen bond with the phenoxide group. Intra-molecular N-H⋯O hydrogen-bonding inter-actions...

Current studies elucidate the metal stress attenuation potential of melatonin in Cucumis sativus seedlings growing in cadmium contaminated conditions. Melatonin is an indoleamine molecule, capable of ameliorating environmental stresses and regulate plant growth. Seeds of C. sativus were immersed in different levels of melatonin and grown under cadmium stress for 15 days. Cadmi...

The hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengthsof sodium perchlorate in a wide pH range, 1-12, and at 25 C. Least squares calculations areconsistent with the formation of M(OH)+, M(OH)2, M(OH)3- and M(OH)42- species, which M isCd2+. The dependency on ionic strength in the background electrolyte solutions was taken intoaccount by using a Debye-Hu...

environmental pollution by heavy metals is a growing global concern. most heavy metals accumulate in the top soil and in the long term, increased concentrations in the soil results in increased absorption and accumulation in plants. the usual concentration of cadmium in the soil is 0.001-2.4 mg/kg of dry soil. the level of absorption and accumulation in plants depends on the type of plant, tiss...
