A review on spectroscopic methods for determination of nitrite and nitrate in environmental samples.
Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2019Nitrate is an important pollutant found in environmental samples. Nitrate and nitrite pose various environmental as well as health hazards. Different methods of determining nitrate in various environmental samples developed during previous years include ...

Determination of 241Pu in the environmental samples
Applied Radiation and Isotopes, 2008More than 70 soil samples were analysed in the last several years; results are in the range 0.10-3.74 Bq/kg dry soil, with a median of 0.49 and mean of 0.59 Bq/kg dry soil. From the analysis of more than 40 moss samples, the range of activity concentration was found to be 0.002-2.80 Bq/kg fresh mass with median 1.00 and mean value 0.30 Bq/kg fresh mass.

Forensic identification with environmental samples
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012The field of forensics aims to understand the physical biomarkers that make each person unique. Recently, it has been discovered that one of the traits that makes us unique from one another are the composition of the microbial communities found throughout our bodies.

Passive sampling in environmental analysis
Journal of Chromatography A, 2008Since its invention more than three decades ago, passive sampling technology has been widely used for environmental monitoring throughout the world. In many cases, it is the only practical means of determining pollution levels caused by numerous anthropogenic chemicals.

A note on 207Bi in environmental samples
Journal of Environmental Radioactivity, 2006Traces of the radionuclide (207)Bi were identified in soil and cryoconite (glacier sediment) samples from Alpine regions of Austria. This nuclide has been produced in thermonuclear explosions mainly in the early 1960s and subsequently dispersed in the atmosphere. Activity concentrations up to 22 Bq/kg d.m. have been found.

Determination of molybdenum in environmental samples
Analytica Chimica Acta, 2007Determination of molybdenum in different kinds of environmental samples is often a challenging task for analysts. Its concentration is usually very low and the sample matrix may cause serious interferences during measurement. Therefore, preconcentration and separation methods should be used to solve these problems and render more sensitive, accurate ...

Environmental Sampling and Analysis for Zeranol
American Industrial Hygiene Association Journal, 1987Due to concern over health effects associated with the use of zeranol, a sampling and analytical method to monitor zeranol in the work environment was developed. The collection strategy included air samples on FHLP filters, area samples on gauze pads, hand/dermal samples on gauze pads and bulk samples.
