The production of certified reference materials in Brazil, and the consequent availability to national end users, is an important task for the enhancement of Metrology in Chemistry status in the country, as these materials are used for method validation, equipment calibration and for establishing metrological traceability links. In this study, Instrumental Neutron Activation Analysis (INAA) was...

Illegal trafficking of pharmaceutical products by criminal organisations is a global threat for public health. Drugs erectile dysfunction such as phosphodiesterase type 5 inhibitors are the most commonly counterfeited medicines in Europe. The search possible toxic chemical substances seized needed to provide early warning Furthermore, elemental profile can be useful investigations. For first ti...

Conventionally used spectrometric techniques of inductively coupled plasma optical emission spectrometry (ICP-OES) and (ICP-MS) usually involve time-consuming sample preparation procedure a dissolution which requires the usage aggressive toxic chemicals. The need for suitable sustainable analytical methods direct multi-elemental analysis plant samples has been increased in recent years. Spectro...

The present paper sheds new light on the alteration of archaeological ceramics buried in marine environments by analysing detail a large dataset Hellenistic and Late Roman Republican transport amphorae from 15 sites along well-known ancient maritime trade route off Dalmatian coast southern Croatia. These include shipwrecks, kiln settlements. Ceramic petrography instrumental neutron activation a...

The heritability of chronic hepatitis in the Labrador Retriever is studied with the aim of identifying the related gene mutation. Identification of cases and controls is largely based on instrumental neutron activation analysis (INAA) Cu determination in liver biopsies. The burden for these companion animals may be reduced if nail clippings and hair (fur) could serve as a noninvasive indicator ...

Inorganic Cr(III) and Cr(VI) have contrasting biological, geochemical and toxicology effects. Cr(III) is considered as an essential species for the proper functioning of living organisms but Cr(VI) is toxic for the biological systems. An off-line speciation method using Chelex-100 has been practiced for speciation to Cr(III) and Cr(VI) from surface waters of rivers. The underlying principal of ...

Beach rock has only rarely been observed in the coasts. It is a hard costal sedimentary formations consisting of various beach sediments, lithified through the precipitation of carbonate cements. One such formation is noted on the South East Coast of Tamilnadu, India. The objective of this contribution is to collect and review information on reported occurrences, characteristics and formation m...

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...

The level of the heavy metal in green tiger shrimp (Penaeus semisulcatus) and crab (Portunus pelagicus) caught off the Persian Gulf near Bushehr province were investigated. This study was performed to evaluate instrumental neutron activation analysis (INAA) to analyze heavy metal concentration in crab and shrimp whole body tissue. The order of the swimmer crab and shrimp heavy metal concentrati...
