This study was conducted to determine the concentration of five heavy metals, including lead, cadmium, mercury, arsenic, and chromium in muscle, liver and gills of the gray mullet, Liza aurata in southern part of the Caspian Sea. The samples were collected during sexual maturity (in the fall) and sexual rest (in the spring). The mean concentration of lead, cadmium, mercury, arsenic, and chromiu...

the aim of this study was measuring the amount of heavy metals (nickel, cobalt, cadmium, chromium and zinc) in different tissues of black fish (capoeta fusca). for this reason, in july 2010, 24 black fish was caught at the central part qanats of birjand. the results showed that between the whole length and the weight of fish and concentration of heavy metals in different observed tissues there ...

normal 0 false false false en-us x-none ar-sa background: cadmium and lead compounds are classified as human carcinogens by several regulatory agencies. twenty five percent of all cancer-related deaths are attributed to gastrointestinal cancers (gi ca). we investigated the levels of 2 different heavy metals (cd and pb) in the soils of the lenjanat region, isfahan province, central iran where in...

alfalfa and maize are important agricultural plants for animal consumption. in this survey, accumulation quantity of heavy metals (fe,zn,mn,cd,pb,ni,cr) in plants irrigated by sewage and well water were compared statistically together and with normal or standard(permeable) limits in plants or foraging, during 2005. the results were as following 1-maize: the value of accumulation in maize irriga...

Phytoremediation is a biological method to improve soils contaminated with heavy metals. The objective of the present research was to study the capability of Vetiver grass and Tall Fescue in refining and reducing pollution of Cd, Cu and Zn from contaminated soils. The research was implemented in greenhouse during two separate tests (Vetiver grass and Tall Fescue) in a completely randomized desi...

Rapid industrialization along with advanced agricultural activities led to the contamination in aquatic environment with heavy metals. Heavy metals ultimately pass into human body through having aquatic animals like fish, prawn and crab. In this study, accumulation of heavy metals (zinc, copper, iron, cadmium and lead) in various organs of four commonly consumed fish (Euthynnus affinis...

 The accumulation of heavy metals Pb and Cd in the mangrove, Avicennia marina, was studied on the southern coast of Iran, particularly on and near Qeshm Island in the Persian Gulf. The samples were collected from 7 stations which they were analyzed by flame Atomic absorption spectrophotometer after chemical digestion. Maximum Pb and Cd in leaves are (34.50, 3.52 ppm) and minimum of th...
