Estimation of the Deposited Aerosol Particles in Baghdad City, using Image Processing Technique

Abstract

ABSTRACT In this study, an algorithm was developed to measure the volume and the covered area by the dust particles, and the radius of dust particle deposited for different time hours of the day. Slices transparent glass has been used to collect samples of dust particle deposited for different time of the day in Rusafa area of Baghdad city, were taken digital image of the samples through an optical microscope (EYEPIECE 10X). What have been noticeable are the difference in radii and areas of dust particles deposited as well as the difference in the density of dust particles for each slice according to time that put the slice to deposition. this paper, Keywords Dust particle, Atmospheric Aerosols. 1. INTRODUCTION Air pollution is one of the important problems in latest decades, with increasing use of fuels from oil and natural gas in various fields of life, spread in the environment many air pollutants such as gases resulting from industrial activities or different modes of transport [1].Air pollutants are classified according to the nature of its presence into two main groups: gaseous pollutants and aerosols. An example of gaseous pollutants and hydrocarbons that exist in the form of organic compounds may be gaseous, liquid or solid, such as sulfur oxides, nitrogen oxides and carbon [2]. The aerosol pollutants other are divided into solid and liquid non-permanent, such as the normal dust and pollen. Aerosol sooner or later precipitates out of the air but gases, containing space which launches it and act like the air and will not precipitate [3]. Aerosol light-absorption measurements are important for health, climate, and visibility applications [4]. Michael D. King et al. (1999) [5] Studied the advantages and disadvantages systems of Remote sensing for aerosol application, Where no one sensor system is capable of providing totally unambiguous information. Also a careful intercomparison of derived products from different sensors, to gather with comprehensive network of ground-based sun photometer and sky radiometer systems. W.Partrick Arnottet. al.(2005)[4] exploited the aerosol optics use in experiment develop a model-based calibration scheme for the 7-wavelength aethalometer, and the photo acoustic instrument operating at 532nm is used to evaluate the filter loading effect caused by aerosol light absorption and multiple scattering theory is used to analytically obtain a filter-loading correction function. G. J. Wong et al. (2007) [6] Studied the temporal development for air quality, was develop the image processing technique for enhancing the capability of an internet video surveillance (IVS) camera for real time air quality monitoring, in this technique could to detect particulate mater with diameter less than 10 micrometers(PM10).Xiaolei Yu et. al. (2011) [7] introduced a relationship between aerosol anthropogenic component and air quality in the city of Wuhan, by used satellite remote sensing. A. Bagatet. al. (2013) [8] exploit the aerosol optical depth, Angstrom exponent, single scattering albedo, and polarized phase function have been retrieved from polarized sun-photometer measurements for atmosphere. Where the Angstrom exponent has a meaningful variations respect to the changes in the complex refractive index of the aerosol, and the polarized phase function shows a moderate negative correlation respect to aerosol optical depth and single scattering albedo, so polarized phase function became regarded as a key parameter to characterize the aerosol. In measuring system will be introduced for determine radius, covered area by deposited aerosol particle and deposited aerosol particle volume as a function of day time, will be calculated by using image analysis and computer algorithms.
