Concentrations of Some Trace Metals in the Tissues of Two Commercial Fishes from Tonekabon
In this study, concentrations of mercury (Hg) and 16 other elements as well as methylmercury speciation were quantified in muscle and liver of two commercial fish species. It was also our intention to evaluate potential risks to human health associated with seafood consumption. The fish species, Mullet and Kutum (Caspian White fish) fishes, were obtained from Tonekabon at the Iranian waters of ...
متن کاملTrace Metals and Major Elements in Sediments of the Northern Persian Gulf
The concentrations of sixteen elements and organic carbon were determined in 78 marine sediment samples collected from the Iranian coastal waters of the Persian Gulf. Nine transects perpendicular to the coastline were sampled. Sixteen elements, including As, Ba, Cd, Co, Cu, Mn, Ni, Pb, Zn (trace metals) and Ca, Fe, Mg, Na, P, S, Si (major metals), were determined by Inductively Coupled Plasma M...
متن کاملMicro-pixe analysis in invasive ductal carcinoma tissues after treatment of astaxanthin
Background: Trace elements play an important role in a number of biological processes. Astaxanthin (ASX), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. This work intended to understand the effect of Astaxanthin in breast cancer (invasive ductal carcinoma, IDC) by using micro-pixe method. For this aim the concentratio...
متن کاملSelected trace elements evaluation in soil from an urban farming area
BACKGROUND AND OBJECTIVES: Urban farming makes a substantial influence on the household economy of the urban poor especially in developing countries. Urban soil the hot spot of urban farming is a natural sink for contaminants especially the trace elements derived mainly from anthropogenic activities. This study’s aim was to quantify the concentrations of selected trace elements...
متن کاملDetermining 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) ...
