This study was carried out between October 2009 to July 2010 and heavy metals like Ba, As, Co, Cd, Cr, Cu, Fe, Mn, Ni and Zn were determined from water and 60 fish samples (60 in total) from Antalya Bay. Physic-chemical parameter values were also measured in the seawater from catchment area. Analysis of DORM-3 and DOLT-4, reference materials showed good accuracy with the present analytic system...
background: the concentrations of heavy metals in the tissues and organs of fishes indicate the concentrations of heavy metals in water and their accumulation in food chains. in the present study, the concentrations of zn, cu, cd, ni, v and pb in three common species of fish and the potential health risks to local residents via consumption of the fishes were estimated. methods: the concentrati...
Introduction: Bioaccumulation Capacity of Heavy metals in aquatic bodies can do a serious threat to food security and public health. Therefore, in this study, the amount of lead, cadmium and copper in edible tissues of hydrothermal fish in Alborz province was determined in 2017. Materials and Methods: Twenty-one carp fish of three species were randomly selected from the Mahmoudi fishery, which ...
the proteins in fish, as well as other aquatic animals has nowadays become an important and complete protein sources in many people’s diets around the world and as a results, there has been a growing interest to protect and ensure the health of this important food source. heavy metals due to their specific physical and chemical characteristics as well as their effects on various ecosystems are ...
Heavy metals such as copper and zinc are essential for fish and human metabolism. But excessive concentrations of heavy metals impair ecosystems as some of those cause potential bioaccumulation in live beings. Fish are the major inhabitants in water bodies and can be highly affected by these toxic pollutants. The presence of these contminations in fish is known to cause various diseases in huma...
The present study was performed to measure heavy metals (Pb, Zn, Cd and Cu) in the muscle, liver, gonad, intestine and digestive parasites of Pike (Esox lucius) in Anzali wetland. For this purpose, 90 fish Pike were sampled from Anzali wetland during 2020 and in the reproductive season (winter). During the experiment, total length, fork length, standard length and total weight were measured. Th...
In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...
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 objectives: despite the increasing impact of heavy metal pollution in persian gulf due to urban growth and agricultural and petroleum activities, few studies have focused on the behavior and relationships of these pollutants in the biotic and abiotic components of aquatic environments. in this study, the amount of some metals (copper, iron, lead, cadmium, zinc and nickel) was det...
