With the rapid economic development in recent years, China is facing a great challenge due to heavy metal pollution. The heavy metals may enter the human body through ingestion of aqua products to cause great health risks. In the present study, the inhibitory effects of luteolin on the combined toxicity of multi-heavy metals (including zinc, manganese, lead, copper, cadmium, mercury, chromium a...

In the present study, the water quality of Silakhor River, located in Rahim Abad hydrometric station, was analyzed based on Boron, Iron, Nickel, Fluorine, Manganese, Chromium, Cadmium, Aluminum, Copper, Zinc and Lead pollution. The samples were collected from Silakhor River in Rahim Abad hydrometric station during a one-year period, from December 2012 to November 2013. In addition, metal index ...

The theory of relativity cannot be neglected if structures and properties of compounds containing heavy elements are discussed. The assumption of a constant speed of light implicates an increase of the mass and thus of the momentum of the electrons, especially close to the nucleus, amounting to more than 20% for the heavy elements belonging to the groups 13 – 18. One of the consequences is a re...

batch adsorption experiments were performed to study adsorption potential of agricultural residues viz. rice straw, wheat straw and salvinia plant biomass for removal of heavy metals such as cr, ni, and cd. plant materials were used in different combinations. heavy metal removal efficiency was more at low metal concentration (35 mg/l). salvinia biomass possessed higher efficiency for removing h...

Halomonas zincidurans strain B6 was isolated from a deep-sea heavy metal rich sediment from the South Atlantic Mid-Ocean Ridge. The strain showed significant resistance to heavy metals, especially to zinc. Here we describe the genome sequence and annotation, as well as the features, of the organism. The genome contains 3,325 protein-coding genes (2,848 with predicted functions), 61 tRNA genes a...

To detect heavy metal contents in fruits rapidly, the Citrus Nanfeng tangerines pericarp and flesh have been analyzed by laser induced breakdown spectroscopy. Line emissions from five heavy metal elements, Pb, Cd, Hg,Cr and As, have been clearly extracted. Their intensities correspond to relative concentrations of these elements contained in the analyzed samples. The results demonstrated that t...

Rare-earth (R) transition-metal (T) compounds of the R(T,M)12-type with R = Y or one of the heavy-rare-earth elements, T = Fe or Co and M = Ti, V, Mo or Si, have been studied at 4.2 K in the Amsterdam High-Field Installation in magnetic fields up to 38 T and at temperatures between 4.2 and 1000 K in other magnetometers. The 4f -3d interaction is derived from magnetization measurements on single...
