Dust is one of the environmental problems in Kerman city. Due to the major aspect of mineralogy in environmental studies, mineralogy and chemical studies of dust in different regions of the city performed by microscopic thin sections, x ray diffraction (XRD) and ICP-MS. In all areas of the city, minerals such as calcite, quartz, feldspar, pyroxene, micas, Jaffeite, gismondine and clay mineral w...
Electrochemistry combined on-line with inductively coupled plasma-atomic emission spectrometry (EC/ICP-AES) was used to study the electrode reactions of rabbit liver metallothionein (MT) adsorbates at thin mercury films (TMFs). Three major oxidation peaks, with peak potentials at −1.20, −0.75 and −0.32 V, were observed. Through the correlation of the DPV characteristics to the elution of the Zn...
The binding of Cu, Fe, Mn, and Zn to proteins in blood and in blood fractions was investigated, since their interactions in free radical metabolism in humans is of great interest. An HPLC-ICP-AES technique was developed allowing adequate separation of metalloproteins and of inorganic and organic metal species. For the separation of metalloproteins in erythrocytes and blood plasma a Merck Superf...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
The relationship between the concentration of heavy metals and physicochemical factors was studied in the fine-grained sediments of the tidal section of the Mehran delta where mangrove trees have grown. Surface sediments of the tidal zone of the Mehran delta were sampled. The grain size distribution, calcium carbonate, organic matter contents, pH/Eh, and heavy metals concentration were determin...
The Yanbu industrial city along the Red Sea coast includes industries associated with crude oil and natural gas production refining support that produce manufactured goods for domestic and/or internal consumption. This study investigates potential environmental impact possible sources of heavy metals (HMs), it evaluates quality coastal surface seawater in vicinity Yanbu, Saudi Arabia. Thirty sa...
background : heavy metals and pah s in flue gas have received considerable attention in recent years due to their mutagenic or carcinogenic properties. pah s are products of incomplete combustion of carbonaceous compounds at high temperatures. heavy metals are released into the ambient air from the same sources as those earlier mentioned for pah s . the present study was carried out to investig...
Agricultural researchers in many countries investigate radiological risks soil and crops because it concerns human health. In addition, they also study heavy metal pollution plants cultivated for ecological safety. This aims to analyze the activity concentrations of radionuclides metals corn Küçük Menderes Basin (Izmir, Turkey) – which is enriched with phosphatic fertilizers. We collected sampl...
this study aims to investigate value conflicts between mothers and their daughters among families and influential factors on this conflict in yazd city. this study adopted a survey method and a questionnaire was used that its validity through construct validity (factor analysis) and its reliability by cronbach alpha were measured. the population of this study consists of all yazdian families th...
Background: Evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. Methods: In this study, total an...
