due to environmental problems caused by mining activities, it is necessary to study and investigation the concentrations of the pollutants caused by this activities such as heavy metals. the aim of this study is the determination of the concentration of heavy metals cu, pb and zn in roots of two species of artemisia including artemisia aucheri and artemisia sieberi in the surrounding natural la...

Introduction: In recent years, attraction toward drinking bottled mineral water has increased. Therefore, chemical composition and safety of these waters considering trace elements and heavy metals should confirm the national or international standard limits. The aim of this study was to evaluate and comparison of the mineral and heavy metal composition of bottled waters in Bandar Abbas with Ir...

Concentrations of essential (copper, iron, manganese, selenium, and zinc) and non-essential (arsenic, cadmium, mercury, and lead) trace elements were measured in arms of Octopus vulgaris. The cephalopods were sampled from commercial fishery landings at two sites on the Portuguese coast in spring 2002 and 2003. Mercury was determined using an Advanced Mercury Analyser Spectrophotometer (AMAS) an...

background: anthropogenic activities release high concentrations of heavy metals into the aquatic ecosystems, which can be absorbed by the aquatic organisms. in this study, the accu-mulation of cadmium (cd) and arsenic (as) was compared in liver, gill and muscle tissues of toothed carp (aphanius sophiae) in fresh and salt water. methods: a total of 175 fish samples were collected from the shoor...

This study aims to determine the toxic effects of heavy metal pollution on carp (Cyprinus carpio) in Sapanca Lake by biochemical and histological analyses. For this reason, fish water samples were taken from lake 2015. Heavy (Cu, Fe, Zn, Pb, Cd) analyzes column tissues (muscle, liver, gill) determined ICP-OES. CAT, GSH MDA levels, which are oxidative stress bioindicators tissues, measured spect...

background: soil and sediment serve as major reservoir for contaminants as they possess ability to bind various chemicals together. in this study the concentrations of heavy metals cd, cr and cu were analyzed in surface sediments of agh gel wetland in west of iran. methods: the sediment samples were taken from 10 stations. the samples were subjected to bulk digestion and chemical partitioning a...

in the industrial area of elefsis, greece, aerosol samples from the atmosphere were collected using a stacked filter unit sampler, which separates the airborne particulate matter into coarse (pm2.5-10) and fine (pm2.5) size fractions. the samples collected during the period january 2005 to march 2006, were analyzed by anodic stripping voltammetry (asv) and inductively coupled plasma atomic emis...
