ría and coastal zone are, in particular, vulnerable to heavy metals pollution. concentrations of 10 metals in liver, muscle and kidney of the sole (solea vulgaris) from ría of vigo and its coastal zone (spain) were measured from april 2006 to february 2007 and the relationships between fish size age and metal concentrations in the tissues was investigated. concentrations of the heavy metals in...

Four heavy metals were measured in forty-nine topsoil samples collected fromagricultural areas in Siakh-Darengoun, Iran. The goals were to investigate soil spatialdistribution patterns of metals; their potential ecological risk; and sources. The Hakansonpotential ecological risk index and index of geo-accumulation (Igeo) were used forevaluating t...

the use of fertilizers npk and amendments in sugar cane crops may change the heavy metalsconcentrations in soils, making them available for plants and, consequently, they can be transferred to thehuman food chain. this study describes the redistribution of heavy metals (cd, cr, cu, ni, pb and zn) in soils with sugar cane crops due to fertilizers npk and amendments at corumbataí river basin, são...

background: persian gulf is a semi-closed environment which is affected by pollution ‎from heavy metals. entrance of heavy metals to the water column and binding to ‎sediment particles can affect the benthic organisms that can accumulate these ‎materials in their body. noticing this ability, mussels are considered as bio-monitoring ‎agents.‎ methods: the pearl oyster, pinctada radiate, and sedi...

Introduction: Road dust is a group of solid particles that are presented in the urban areas and are originated from both natural and human-induced sources. This study aims to determine concentrations of heavy metals in urban dusts in Behbahan to identify their natural or anthropogenic sources. Materials and Methods: In this study, a total of 20 samples were collected from main roads with diffe...

the objective of this study was to explore the application of hybrid artificial neural network methods to predict heavy metals in rainwater based on major elements. measurements of the heavy metals pb, cu, zn, as, ni, hg, and fe in soluble rain fractions were performed in rainwater collected at the arak plain during the rainy seasons of 2012. in the soluble fractions, the concentrations of the ...

In this study, heavy metals (Hg,Cd,Pb,Cu,Zn) and metallothionein (MT) biosynthesis were measured in blood of green sea turtles (Chelonia mydas) nesting on the northern coast of the Sea of Oman. Heavy metals concentrations in the sea water, the sediments, the blood samples ranged between 0.02-8.43 μg/l, 0.06-10.32 μg/l, and 0.16-36.78μg/g (ww), respectively.The highest concentration...
