Monitoring and Reporting VOCs in Ambient Air
Volatile organic compounds (VOCs) are part of the large hydrocarbon family, a vast array of aliphatic, aromatic hydrocarbons, their halogenated derivatives, alcohols, ketones and aldehydes. VOCs have a property of conversion into vapour or gas without any chemical change. They are highly reactive hydrocarbons and participate in atmospheric photochemical reactions. Some of them have negligible p...
متن کاملParameter Optimization for the Measurement of VOCs by Canister System
with growing concern for quality of the environment, demand for reliable and sensitive monitoring techniques for organic compounds in the atmosphere has increased recently. Canister sampling and analysis is becoming a widely accepted choice for the measurement of volatile organic compounds (VOCs). Before carrying out any measurement it is necessary to optimize parameters in order to get reprodu...
متن کاملOccurrence and Concentrations of Toxic VOCs in the Ambient Air of Gumi, an Electronics-Industrial City in Korea
This study was carried out to characterize the occurrence and concentrations of a variety of volatile organic compounds (VOCs) including aliphatic, aromatic, halogenated, nitrogenous, and carbonyl compounds, in the ambient air of Gumi City, where a large number of electronics industries are found. Two field monitoring campaigns were conducted for a one year period in 2003/2004 and 2010/2011 at ...
متن کاملMonitoring and Zoning of PM2.5, PM10 and VOCs Concentration in Air of Gorgan City in 2016
Background & Aim: Increasing of air pollution in cities seriously threatens the health of its inhabitants. PM2.5, PM10 and volatile organic compounds are amongst the air pollutants that their existence in the air in excess concentrations, leads to respiratory and cardiovascular problems, cancer and mortality. Therefore, the concentration of these pollutants in the air of Gorgan city was measur...
متن کاملA simple and safe method for preparation of Mg(OH)2 nanorods in ambient air
Magnesium hydroxide Mg(OH)2 nanorods with diameters of 90±10nm and lengths of more than 2μms were prepared by a simple route at ~75oC in ambient air. The approach is based on reaction of magnesium powder and de-ionized water without the use of any harmful, toxic or corrosive reagents. Characterization using X-ray diffraction (XRD) shows single crystalline structure of Mg(O...
