Aug 22, 2012 Purpose To assess how the rates of humus formation and humification are affected by land use and age of ecosystems, this study investigated soil development in two post-mining chronosequences spoil heaps formed from open-cast coal mining near Sokolov, Czech Republic. The following characteristics were measured content, composition, and properties of humic acids organic carbon C and total ...
by using gamma-spectrometric methods in accordance with Czech National Standard ISO 10703 75 7630 7. Samples of suspended matter were measured for the ac- tivities of 137Cs, 226Ra and 228Ra. The amount of dry sam- ple was about 0.5 kg sediments and 1 - 25 g suspended matter respectively. The results were expressed in Bqkg dry sample.
In the Comparative method, one uses a reference standard, a sample with known emission and absorbance properties close to that of the sample of interest, and has a known PLQY value. The absorbance and fluorescence of the reference standard are measured and then the same is measured for the sample under
Convenience sampling also known as availability sampling is a specific type of non-probability sampling method that relies on data collection from population members who are conveniently available to participate in study. Facebook polls or questions can be mentioned as a popular example for convenience sampling.

Dec 21, 2015 The most common types of mining equipment vary depending whether the work is being carried out above or below ground or mining for gold, metals, coal or crude oil. From drilling machines to excavators, crushing and grinding equipment the mining industry comes complete with all the right tools.
Apr 30, 2012 This method is based on the assumption that a change in response for the sample and the sample with an addition of standard corresponds only to the change of the concentration. For solid samples two techniques can be used the addition of an aqueous standard or the addition of reference material to the solid sample.
total coal consumption. Other major coal-using sectors include the iron and steel sector, independent coke producers, steam raisingfor industry, district heating plants, and direct use of coal and coal products for residential heating. The Czech Republic has experienced some severe environmental problems related to the production and use of coal.
Jul 01, 2003 Exposure to dust and particle-associated 1-nitropyrene 1-NP was studied in 20 miners of black coal by the long wall method Czech Republic and in 20 workers in oil shale mining by the room and pillar method Estonia. The study in the oil shale mine was extended to include 100 workers in a second phase main study.
solid sampling electrothermal atomic absorption spectro-metry SS-ETAAS has been used. The solid samples are weighed on a graphite platform, which is inserted into a graphite tube. The advantages of this method are the use of a very small amount of sample and little sample

Ultra-clean coal UCC from new processing technologies which reduce ash below 0.25 and sulfur to very low levels mean that pulverised coal might be used as fuel for very large marine engines, in place of heavy fuel oil. There are at least two UCC technologies under development. Wastes from UCC are likely to be a problem.
Based on an analysis of related core papers and reports, this review presents a historical perspective on ambient air pollution and ambient air quality development in the modern-day Czech Republic CR over the past seven decades, i.e., from the 1950s to the present. It offers insights into major air pollution problems, reveals the main hot spots and problematic regions and indicates the ...

This study investigated polycyclic aromatic hydrocarbons PAH pollution of selected rivers in the Czech Republic. Integrated evaluation was carried out using combination of chemical and biological monitoring, in which we measured content of 1-hydroxypyrene 1-OHP in chub bile and priority PAH in water samples obtained by exposing the semipermeable membrane devices at each location.
Traditional sampling methods, like cone and quartering, can be time-consuming and involve significant clean-up and still provide you with inferior split. With the Essa RSD Series Bucket Type Rotary Sample Dividers, the whole sample is split and retained, giving you reliable results with a minimum of fuss.
