Transformation of polycyclic aromatic hydrocarbons during sampling.
Individual PAH are shown to undergo chemical transformation when exposed to gases such as NO2, O3 and SO3. The possibility of artifact formation during sampling in stacks and in ambient air is discussed. PAH on soot, formed in a smoke gas generator, and exposed to NO chi and SO chi in a thermostated oven were degraded as a result of the sampling technique. Addition of NO2 (1 ppm) or gaseous HNO...
متن کاملPassive Sampling of Aromatic Hydrocarbons Toluene, Xylene and Ethylbenzene Using Activated Carbon Fabric in Ambient Air of Tehran
Background & Objectives: Air pollution is one of the most important environmental problems in large cities. Aromatic hydrocarbons as volatile organic compounds (VOCs) have been listed in Hazardous Air Pollutants (HAPs) by Environmental Protection Agencies (EPA). The aim of this study is Passive sampling and determination of aromatic hydrocarbons (AHs) toluene, xylene and ethylbenzene using ...

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملTransport of Polycyclic Aromatic Hydrocarbons in a Calcareous Wetland Soil
Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...
