The parameter total suspended solids (TSS) is often used to evaluate the need for stormwater treatment or assess effectiveness of measures. purpose this study analyze value and limitations approach using metals as an example. They are major concern due their accumulating effects in environment. Data a monitoring campaign at facility evaluated. TSS, organic matter associated (Cr, Cu, Zn, Cd, Pb)...
Short-term effects of air pollution (consisting primarily of sulphur dioxide and particulate matter but with low acidity) on respiratory morbidity were studied in asthmatic children from Sokolov, Czech Republic. Eighty nine children with asthma, who recorded daily peak expiratory flow measurements, symptoms and medication use in a diary, were analysed for 7 months during the winter of 1991-1992...
Prediction of the apparent viscosity of a slurry suspended fine particles is important for developing slurrytreating processes. After Einstein’s formulation for the apparent viscosity of a dilute, completely dispersed slurry, several viscosity equations were proposed. However, viscosity depends not only on the volume fraction of solid particles but also on many factors such as particle shape, p...
One of the main causes of air pollution in the arid areas of world, especially in Iran, is the increase of the PM10 concentration. The main objective of this research is to identify the most important climatic factors affecting the change of PM10 concentration near Yazd-Ardakan plain and its relation with wind erosion occurrence during the period from 2012 to 2017. For this purpose, the monthly...
The hydrological conditions, suspended matter concentrations and vertical particulate matter flux were measured as the River Vistula flood wave (maximum discharge) was flowing into the southern part of the Gulf of Gdańsk on 26 May 2010. Extending offshore for several tens of kilometres, the river plume was well stratified, with the upper layer flowing away from the shore and the near-bottom wat...
The problem of two-phase MHD boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. The effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. The governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
In this work, Mn ferrite nanopowders were prepared by co-precipitation method and were characterized. Phase identification of the nanopowders was performed by X-ray diffraction method and the mean particle size of the nanopowders was calculated by Scherrer's formula, using necessary corrections. Magnetic parameters of the prepared nanopowders were measured by a vibrating sample magnetome...
Introduction: Environmental pollution also increased by the advancement of technology and the application of industries in human life. Air pollution is one of the major contaminations in the human environment which causes many acute and chronic diseases. This study was conducted to investigate the contamination of PM2.5 and PM10 particles in Khash Cement Company in Sistan and Baluchestan provin...
An 11 hours survey was performed on the 17th of September 2014 in Rhine Region Of Freshwater Influence (Rhine-ROFI) about 10 km downstream mouth Rotterdam Waterway during calm weather conditions. Suspended Particle Matter (SPM) measurements were a full tidal cycle, near seabed, at neap tide, and samples taken 0.6 meter above bed for on-board analysis. The with (a) LISST 100X, submersible partic...
