GFAAS determination of mercury in muscle samples of fish from Amazon, Brazil.

بررسی غلظت جیوه در آب و ماهی های سواحل جنوبی دریای خزر، ایران

Background and Objective: Mercury (Hg) contamination in marine ecosystems is a major threat to human health in the developing countries like Iran. The main route of mercury exposure is from consumption of fish and seafood. Upon entering mercury in human bodies, Hg is converted into methyl mercury, which may lead to serious implications including neurological disorders, reproductive abnormalitie...

Determining Mercury Contamination in Indian Spiny Turbot, Psettodes erumei, from Jask Port Coastal Waters, Iran

In this research we assessed the concentration of total mercury in the muscle, liver and gill tissues of Indian spiny turbot, Psettodes erumei caught from Jask coastal waters in Hormozgan province. Fifteen fish specimen were caught using trawl in spring season 2008. After biometrical measurements and sex determination, muscle, liver and gill tissues were collected mercury was extracted from the...

Short communication: Determination of total mercury in common carp, Cyprinus carpio, large scaled barb, Barbus grypus, tiger tooth croaker, Otolithes ruber and from surface waters in Khuzestan, Iran

Determining Total Mercury in Samples from the Persian Gulf and theCaspian Sea: Comparison of Dry Ash and Wet Extraction Mothods

Monitoring of mercury in environmental samples, with its proven toxicity on the food chain, requires sensitive and accurate analytical techniques. In this study, two methods for identification and quantification of total mercury in biological and sediment samples are compared: i) dry ash preparation and subsequent established procedures for Combustion Atomic Absorption Spectrometry, (AMA 254) ...

Mercury Biomagnification between Two Trophic Levels of a Grazing Food Chain (Plankton and Planktivorous Fish) in a Fresh Water Ecosystem

Background: The Present study was carried out to track and calculate Biomagnification Factor (BMF) of total mercury (T-Hg) between two different trophic levels (i.e., plankton and a planktivorous fish) in a fresh water grazing food chain. Methods: Experimental organisms were planktonic biomass and silver carp (Hypophthalmichthys molitrix) as a planktivorous fish. Silver carp samples were obt...
