the karoun river is major source of water for warm water fish culture industry in southwest of iran. the aim of the present study was to investigate the distribution of mercury in tissues of marketable common carp and in bottom sediments of fish farms in khouzestan province. this study was carried out on 45 fish farms that are located on the bank of the karoun river in khouzestan province, sout...

Although fish is an important source of nutrients, including some the healthiest proteins, long-chain fatty acids, and essential selenium, species at top food chain frequently contain large amounts toxic mercury (Hg). The provisional tolerable weekly intake (PTWI) Hg from consumption calculated total concentration assuming that all speciated as organic methylmercury (MeHg). Using high energy-re...

The Karoun River is major source of water for warm‌water fish culture industry in southwest of Iran. The aim of the present study was to investigate the distribution of mercury in tissues of marketable common carp and in bottom sediments of fish farms in Khouzestan province.

 The concentrations of Cd, Pb, Ni and Hg were determined in gill, liver and muscle of Barbus xanthopterus in down streams of Karoon and Dez Rivers during summer 2009. Heavy metal concentrations varied significantly, depending on the types of the tissue in fish species. The levels of heavy metals such as Cd, Pb, Ni and Hg in the Barbus xanthopterus of Karoon River were higher than in B...

Background and Objective: Hyperemesis gravidarum (HG) is defined as vomiting sufficiently severe to produce weight loss, dehydration, electrolyte abnormalities. Interleukin-6 (IL-6), a pro-inflammatory and trophoblast-derived cytokine has ability to induce trophoblasts to secrete human chorionic gonadotropin (hCG). The purpose of our study was to assay the level of IL-6 and β-hCG in serum of pr...

As the electrochemical method, the Fast Fourier Transform (FFT) Stripping Cyclic Voltammetry detection method was designed for measurement and monitoring of adsorbed mercury ions by new modified adsorbent based on mesoporous silica as a new adsorbent. In this respect, SBA-15 as mesoporous silica and 1, 3, 5 Trithiane as effective modifier ligand were chosen, and the modification process was car...

mercury is a dangerous and an extremely toxic element, which can transfer to the food chain.presence of this element in the atmosphere particularly during the rainy seasons cause soil and environmental pollution, therefore this research will evaluate the transformation of mercury vapor from the atmosphere through precipitation into the soil. in the present study, mercury concentrations were det...
