The heavy metals concentrations including Zinc, Copper, Lead and Cadmium (Zn, Cu, Pb and Cd) in water and sediments in Gorgan Bay and their accumulation in Rutilus frisii kutum, Acipenser persicus, Rutilus rutilus caspicus and Cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. There was substantial increase in concentration of heavy m...

treatment of soils contaminated with heavy metals using plant species is a method which has been widely used in thepast. this method, which is known as phytoremediation, has been applied for pollution treatment using different plantspecies worldwide. the method has been used for remediation of various types of pollutants in laboratory, pilot andindustrial scales. the aim of this study was to co...

aim: this study was conducted to investigate the accumulation of three heavy metals including lead, tin and zinc in the liver and muscle tissues of 60 silver carp (hypophthalmichthys molitrix) collected from different stations of the anzali wetland (located at the west south of caspian sea): pirbazar, anzali, khazarvila, beshman, sangachin and abkenar, in april 2011. materials and methods: samp...

the main source of heavy metals in soil is the use of urban and industrial waste water, synthetic phosphate fertilizers, sludge from sewage treatment plants. most heavy metals accumulate in the top soil and in the long term, their increased concentration in the soil and accumulation in the plants. the quantity or level of absorption in plants, depends not only on the concentration levels of the...

Heavy metals are regarded as toxic trace elements in the environment. Heavy metal pollution in soil or rice grains is of increasing concern. In this study, 101 pairs of soil and rice samples were collected from the major rice-producing areas along the Yangtze River in China. The soil properties and heavy metal (i.e., Cd, Hg, Pb and Cr) concentrations in the soil and rice grains were analyzed to...

Background & Aims of the Study: The main objectives of the current research were (1) to study the extent of soil pollution by heavy metals (Ag, Cd, Cr, Cu, Mn, Ni, Pb, Zn, Ba and Li) in sampling locations (2) to investigate the extent of heavy metal pollution and soil to plant transfer of these elements in wheat and barley (3) to study the health risk of heavy metals via consum...
