Background: In addition to gas pollutants, many chemicals and air pollutants are in the form of particulate matter. Particulate matter consists of a complex mixture of variable sized particles and physicochemical composition. These particles mainly contain minerals including Fe, Al, Ca, K, Cu, Ti, Mn, Ni, V and their size, chemical composition and concentration are important to assess ...

Introduction Archaeochemists are called on to analyze a wide variety of samples, ranging from metals, pigments, and glasses to bones, stones, and soils. In most cases these samples are solids. Although non-destructive and/or micro-sample analyses are preferable for these cultural resources, in many cases there is a large amount of material available for analysis. In those instances where non-de...

To assess the geochemical features of sedimentary material Zarafshon river, (Western Tajikistan) catchment basin, mass fractions 38 major and trace elements were determined by Instrumental Neutron Activation Analysis (INAA) in 2 × 116 paired samples sediments soils collected along River its main tributaries from sources to Tajik—Uzbek border. At each collecting location, distance between soils’...

The article presents the results of studying mineralogical and geochemical features coals clay interlayers Shubarkol deposit. There were analyzed 71 samples layers 49 coal using instrumental neutron activation analysis (INAA), powder X-ray diffractometry, scanning electron microscopy. A comprehensive characteristics their enclosing was carried out. variety criteria made it possible to establish...

Introduction: A precise knowledge of bulk chemical compositions of chondrules is not only essential for understanding the relationship between chondrules and matrix [e.g. 1], but also for constraining the chondrule forming mechanism [2]. Despite the given importance, relatively few data sets for chondrule bulk chemical compositions are available in the literature, especially for the most primit...

Trace elements play a significant role in biological processes. The aim of this study was to evaluate the trace elements of interest in kidney disease in commonly consumed greenhouse vegetables in Isfahan, Iran. Six kinds of greenhouse vegetables namely; Raphanus sativus (Radish), Cucumis sativus (Cucamber), Solanum lycopersicum (Tomato), green Capsicum annuum (Green bell pepper), yellow Capsic...

introduction there is a growing interest in determining the concentration of various elements in food spices. in the present study, the instrumental neutron activation analysis (inaa) was employed to measure the trace elements in 11 commonly food spices consumed in tehran, iran. materials and methods the levels of k, mn, na, cl, v, br, al, and as were determined and their effects on human healt...

In this paper, the contamination level of fourteen elements (Al, Ca, Mg, V, Ti, Na, Mn, As, Br, La, Sm, Sc, U, Yb) from different soil samples of the nuclear reactor surrounding areas in Savar, Bangladesh was investigated with instrumental neutron activation analysis (INAA) method. Generally, neutron activation is most reliable tool for determining the concentration of the trace elements and he...
