Introduction: Today, have been approved scientifically relationship between presence of asbestos fibers in the human respiratory area and malignant diseases such as lung advanced fibrosis (Asbestosis), gastrointestinal, lung and Laryngeal cancers. The aim of this study was the determination of asbestos fibers concentration in Yazd city’s air in the summer of 2015. Materials and Methods: ...

[ 3 ] - تحلیل فضایی آلاینده‌های شاخص هوا و مرگ و میر منتسب در شهر اصفهان ‌

Introduction and purpose: Long term exposure to air pollutants can result in the development and acceleration of various conditions, such as cardiac and respiratory problems, reduced lung function, chronic bronchitis, asthma, pulmonary cancer, and even death. Regarding this, the aim of the present study was to perform a spatial analysis of air pollution and mortality in Isfahan,...

[ 4 ] - Optimization and Modeling of Microcystin-LR Degradation by TiO2 Photocatalyst Using Response Surface Methodology

Introduction: Microcystin-leucine arginine (MC-LR) is a toxin with harmful effects on the liver, kidney, heart, and gastrointestinal tract. So, effective removal of MC-LR from water resources is of great importance. The aim of this study was to remove microcystin-LR (MC-LR) from aqueous solution by Titanium Dioxide (TiO2). Materials and Methods: In the present study, TiO2, as a semiconductor, ...

[ 5 ] - A Protocol for Pollution Index, Source Identification, and Spatial Analysis of Heavy Metals in Top Soil

Introduction: This study aimed to assess a good protocol for the contamination indexes, concentration, spatial analysis, and source identification of toxic metals in top soils. Materials and Methods: In the first step, samples were taken from top soil (30 cm) and the metals were extracted and detected with ICP-AES. In the second step, Enrichment Factor, Geoaccumulation Index, and Contamination...
