How important are atmospheric depressions and mobile cyclones for emitting mineral dust aerosol in North Africa?
This study presents the first quantitative estimate of the mineral dust emission associated with atmospheric depressions and migrating, long-lived cyclones in North Africa. Atmospheric depressions are automatically tracked at 925 hPa based on ERA-Interim data from the European Centre 5 for Medium-Range Weather Forecasts for 1989−2008. A set of filter criteria is applied to identify migrating, l...

Introduction: Control of fugitative dust from mining process and application of an appropriate and economical system for dust collecting is essential. The goal of this study was cost-benefit analysis of an integrated systems and compare to bag filter in a crushing plant of a mining company. Methods: A local exhaust ventilation system for capture of emitted particlees, a water spray for dus...

Background and aims: Extensive industrial and production activities are one of the major sources of dust. In many cases, cyclones are used as the control measure. The removal efficiency of dust in cyclones depends on different factors. Some of these factors are, the design parameters, e.g. cyclone diameter, particle density, operating temperature and fluid physical properties, density of gas ...

Introduction & Objective: Determination of free silica to calculate threshold limit value is necessary. The purpose of this research was study of free silica in particulate emission in ambient air of stone crushing workshops in Azandarian area. Materials & Methods: 40 samples of respirable dust from workplace air were obtained in breathing zone of workers in different job stations. Samples...
متن کاملAn Assessment of Wind Erosion Schemes in Dust Emission Simulations over the Middle East
Extended abstract 1- INTRODUCTION Atmospheric aerosols, solid and liquid particles in the atmosphere, play a crucial role in the atmospheric radiation equilibrium. These particles have an influence on the scattering and absorption of short wavelength radiation, and on the other hand, affect radiation absorption and emission in long wavelengths. Dust particles are among the importan...
