OBJECTIVE To determine the metal contents of date palm (Pheonix dactylifera) samples in dry season from Denizli-Turkey for investigation of heavy metal-polluted traffic. METHOD The levels of iron, copper, zinc, lead, cadmium, nickel, chromium, and manganese ions in the leaves of thirty five date palm (Pheonix dactylifera) samples collected from various levels of traffic in the streets of Deni...

the removal of copper (ii), zinc (ii), and chromium (iii) from wastewater by carrot residues(cr) was investigated to evaluate cation exchange capacity. the effects of solution ph and co- ions werestudied in batch experiments. adsorption equilibria were initially rapidly established, and then decreasedmarkedly after 10 min. column experiments were carried out in a glass column filled with cr toe...

Aquatic agriculture in heavy-metal-polluted coastal areas faces major problems due to heavy metal transfer into aquatic organisms, leading to various unexpected changes in nutrition and primary and/or secondary metabolism. In the present study, the dual role of heavy metal copper (Cu) played in the metabolism of photosynthetic organism, the edible seaweed Sargassum fusiforme, was evaluated by c...

Present review paper deals with extensive literature survey in exploring the potential of microbial biomass for the sequestering of toxic heavy metals from aquatic streams. Presently more than half billion people are underprivileged and deprived of fresh water, clean air, soil and pure food. Contamination of aquatic streams due to release of toxic metal ions is a stern issue demanding global co...

Fish serum may reflect status of many biochemical processes in the metabolism. Heavy metals may alter serum biochemical parameters in fishes. In this study, the effect of Cr(VI) and Al(III) in fresh water fish I.Punctatus and neutralize these metals by using dead fungal biomass. Activity of serum enzymes AST, ALT, ALP, CPK, LDH and α – amylase in aluminium and chromium exposed fish. The above s...

The present study was conducted to assess the risk to human health by microbial load and heavy metals (Cr, Cu, Ni, Zn, Cd and Pb) through the intake of locally grown vegetables irrigated by metal contaminated water and waste water in Delhi and NCR region. Twenty-two varieties of vegetables grown in the agricultural land were collected for analysis. The results revealed that concentrations of co...

A biofilm of Arthrobacter viscosus supported on granular activated carbon was used to remove chromium and organic compounds (chlorophenol, phenol and o-cresol) from aqueous solutions. The compounds were studied as single solutes and in different combinations between them and Cr(VI). Optimum Cr(VI) adsorption was observed at a phenol concentration of 100 mg/l and at an initial concentration of t...

phenotypic and genotypic diversity as well as symbiotic effectiveness of twenty one symbionts isolated from nodules of four acacia species (acacia melanoxylon, a. mearnsii, a. saligna and acacia tortillis) grown in morocco were evaluated. growth in various media (yma, yma-bbt, yma-rc), colony morphology, tolerance to stress factors (temperature, ph, salt concentrations, various heavy metals) an...
