Nowadays, discharge of toxic heavy metals into the environment is anincreasing global concern. In light of this and that the per capita consumption of mushrooms has increased in Iran, the current study was carried out to investigate the levels and health-risk assessment of elements arsenic (As) and zinc (Zn) through consumption of button mushrooms marketed in Kermanshah city in 2016.In this des...

Increasing consumption of chicken products in Iran makes it very important to analyze their residual heavy metal contents; therefore, the present study has been conducted to determine Pb, Cd, Cr, and Cu in commercial hen eggs, marketed in the city of Hamedan in 2016. In this descriptive study, a sum of 27 samples of hen eggs has been collected from the Hamedan City's market. After preparation a...

IVANOVA, E., T. STAYKOVA and I. VELCHEVA, 2008. Cytotoxicity and genotoxicity of heavy metal and cyanide-contaminated waters in some regions for production and processing of ore in Bulgaria. Bulg. J. Agric. Sci., 14: 262-268 This study generalizes the data of investigations on cytotoxic and genotoxic effect of heavy metaland cyanide-contaminated waters in 2001, 2003 and 2005. The water samples ...

In this study, heavy metals (Hg,Cd,Pb,Cu,Zn) and metallothionein (MT) biosynthesis were measured in blood of green sea turtles (Chelonia mydas) nesting on the northern coast of the Sea of Oman. Heavy metals concentrations in the sea water, the sediments, the blood samples ranged between 0.02-8.43 μg/l, 0.06-10.32 μg/l, and 0.16-36.78μg/g (ww), respectively.The highest concentration...

Airborne particulate matter (PM10 ) was collected from the atmosphere of the city of Isfahan. The concentration of heavy metals and anions associated with airborne particulate matter were determined using atomic absorption spectrometric and ion chromatographic techniques. A comparison was made between the variation in the concentration of PM10 and that for heavy metals and...

Thermal cracking of heavy oil residues has gained the attention refineries due to increasing need for light fractions, as well its lower value compared fractions. In this paper, thermal process residual crude that product from atmospheric distillation towers in Samawah Refinery was studied order convert into a lighter oil. API gravity and conversion ratio result been adopted indicators accuracy...

background: given the importance of vegetables in the food pyramid, their safety is very important from view point of public health. vegetable contamination by heavy metals can lead to bioaccumulation of these toxic and disease-causing elements in the body of consumers. therefore, in this study, the concentration of some heavy metals, including lead (pb), cadmium (cd), zinc (zn) and copper (cu)...

The new Kennecott Utah Copper smelter, started in 1995, was designed to be the cleanest smelter environmentally in the world. The plant is operating at production rates above the original design capacity. Copper concentrate is smelted in an Outokumpu flash smelting furnace. Matte is granulated and processed using Kennecott-Outokumpu flash converting. Copper anodes are processed in a modernized ...

abstract         heavy metals have raised one of the most important problems in ecology and organisms life especially human being and animals. a variety of indicators including tissues of fish, birds and sediment have been used recently to measure the aquatic pollution with heavy metals. the aim of this study was to search the published articles in iran and the world on the role of helminthic p...

background foods are enriched with variety of chemical elements. some of these elements are necessary for human health. these elements enter in liquid, the cells and other organs, certain amount of these elements are essential for body organs to work properly. objectives this research was conducted to compare the level of lead and cadmium contamination in garlic species planted in ramhormoz and...
