The purpose of the Enhanced Particulate Matter Surveillance Program was to provide scientifically founded information on the chemical and physical properties of dust collected over a period of approximately 1 year in Djibouti, Afghanistan (Bagram, Khowst), Qatar, United Arab Emirates, Iraq (Balad, Baghdad, Tallil, Tikrit, Taji, Al Asad), and Kuwait (northern, central, coastal, and southern regi...
Introduction: Particulate matter (PM) increases the risk of heart disorders. Gallic acid (GA) with strong antioxidant properties has shown an effective role in reducing the complications of various diseases. The aim of this study was to evaluate the protective effect of Gallic acid in preventing cardiac arrhythmias due to exposure to particulate matter. Methods: In this study, 40 rats were pla...
Abstract Background: Urban air pollution represents a challenge in Tehran. Health care organs and physicians pay much attention because of health effect on mankind. Nowadays, a majority of air pollution related articles focus on particulate matter adverse effects on human health. Epidemiologic studies show the direct correlation between ambient particulate matter and risk of respiratory sys...
Backgrounds and Objectives: The dispersion of particulate matter has been known as the most serious environmental pollution of cement plants. In the present work, dispersion of the particulate matter from stack of Kerman Cement Plant was investigated using Computational Fluid Dynamics (CFD) modeling.Materials and Methods: In order to study the dispersion of particulate matter from the stack, a ...
under the contemporary scenario of global climate change and increasing coastal eutrophication, baseline studies of phytoplankton diversity and distribution in relation to habitat conditions constitute the first approach to evaluate potential shifts at the base of the food webs. here we present data of phytoplankton species composition and environmental variables in winter 2006 in a temperate e...
This paper presents a non-contact sensing system for nanosized suspended particulate matter (SPM) measurements using laser-induced incandescence (LII) and laser-induced breakdown spectroscopy (LIBS). The elemental composition and density of the SPMs are determined using LIBS, and particulate size measurements are accomplished using LII. Typically, temporally resolved LII enables measurement of ...
Airborne suspended particulate matter is an important marker of air quality. The term 'particulates' includes organic and inorganic matter, nitrogen compounds, sulphur compounds, polycyclic aromatic hydrocarbons (PAHs), several heavy metals, and radionuclides. The health risks from the 'classic' pollutants sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, and particulates have been comp...
