Abstract: Blasting is a set of complex actions for which, in addition to proper calculations and methodology, safety is most important factor. Safety and accuracy increase can be determined from previous blasts in similar environments, but even one parameter changes, it is very important to achieve the optimal conditions thru control measurements. The seismic impact of blasting is a very important part when designing a blasting works. The basic parameter on which further activity is based during the calculation is the oscillation velocity. With the increasing expansion of cities and settlements, there is a need for increasingly demanding blasting that takes place near inhabited facilities. To accurately determine the impact and permissible charge weight per delay that will not damage surrounding structures, various control and testing methods are used. To achieve accurate results, we need as many control measurements as possible and thus show that blasting and all accompanying activities can be

Abstract: A simple and rapid method has been developed using liquid–liquid extraction coupled with gas chromatography–mass spectrometry to extract and determine the organic pollutants in industrial wastewater effluents and treated water samples. Parameters affecting the liquid – liquid extraction performance, such as solvent selection and volume of the sample and the extractive solvent, were studied. Parameters for separation and detection of contaminants were adopted. The developed method was used for the determination of the pollutants in treated industrial water samples.
