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 Sh...

In present study, effect sublethal concentrations lindane (0.025, 0.05 0.1 mg/l) different tissues C. punctatus exposed for 96h has been studied. data showed decrease (AcP) activ...
Bioaccumulation of Cu, Zn, Hg in muscles and liver tissues of stellate sturgeon (Acipenser stellatus) from the southern Caspian Sea was measured. Effects of condition factor (CF), age and hepatosomatic index (HSI) on metal accumulation were also determined. Some 40 stellate sturgeons were collected using gill nets in winter and spring 2007-2008 from the southern shores of the Caspian S...
background: considering high importance of heavy metals residue from view point of food safety, this study was conducted to determine the contents of chromium (cr), lead (pb) and cadmium (cd) in different tissues (liver, heart and muscle) of marketed chickens in mashhad, iran. methods: chicken tissues were collected from four popular brands distributed in different markets in mashhad, followed ...
The major objective of this study was to investigate heavy metal content of black pomfret (Parastromateus niger ). The concentrations of Zn, Cu, As and Cd were determined in external (gill and shell) and internal organs (muscle and liver) of black pomfret in northwest of Persian Gulf in summer 2013. A total of 60 specimens were collected from fishing bottom trawlers. Concentrations of these hea...

در این پایان نامه مباحثی در مورد نیم گروه های معکوس توپولوژیکی اولیه (مطلقا) h-بسته و فشرده (شمارایی) بدست می آوریم و ساختار نیم گروه های معکوس توپولوژی فشرده شمارایی و نیم گروه های معکوس توپولوژی همنهشت-آزاد را توصیف می کنیم و نشان می دهیم که نیم گروه دو دوری نمی تواند در نیم گروه معکوس توپولوژی فشرده شمارایی نشانده شود. we present some discussions about compact (countably) and (absolutely) h...
Background and purpose: There is an increasing interest towards consumption of aquatic products, therefore, the health of aqua ecosystems is highly important. Heavy metal pollution in fish is a global concern due to its bioaccumulation potential, toxicity and persistence in food chain. This study investigated the concentration of heavy metals (cadmium, lead, chromium, copper, and zinc) in the g...
