Abstract
Twelve air samples were collected from four sampling locations namely Transcorp Power Station, Warri Refinery and Petrochemical Company, Amukpe Flow Station and Platform Petroleum Company and were analyzed for the presence of volatile organic compounds (VOCs). Triplicate samplings were carried out within three months for fourteen days using the passive method. After collection, digestion and extraction, VOCs concentrations in each sample were determined with Gas Chromatography equipped with Mass Spectrophotometer (GC/MS). Mean results of analysis showed VOCs in the range of 1.21 - 60.30, 9.12 – 30.80, 5.38 – 66.94 and 7.22 – 101.30µg/m<sup>3</sup> for Transcorp Power Station, Warri Refinery and Petrochemical Company, Amukpe Flow Station and Platform Petroleum Company respectively. Results obtained found all the study location to be contaminated with VOCs when compared with critical values for air quality guidelines. It was therefore recommended that as individuals, we should consider the consequences of our actions and work to improve the quality of air for future generation.
Highlights
Pure air comprise of Oxygen (21%) and Nitrogen (78%) and a number of rare gases, of which Argon is the most plentiful
The objective of this study is to quantitatively analyse Volatile Organic Compounds (VOCs) associated with the atmosphere at some selected flow station in Delta State, Nigeria using Gas Chromatography equipped with Mass Spectrophotometer (GC/MS) techniques; determine the level of significant difference across the studied locations; and determine the VOCs effects in the studied locations by comparing quantitative value with guideline provided by Occupation Safety for Health and Administration
Volatile Organic Compounds (VOCs) components were collected by the use of glass tubes opened at one end
Summary
Pure air comprise of Oxygen (21%) and Nitrogen (78%) and a number of rare gases, of which Argon is the most plentiful. The Atmosphere contain number of gases which at higher than usual concentration are harmful to human. This include Volatile Organic Compounds (VOCs) which are carcinogenic such as benzene and 1, 3 – butadiene. They are potentially toxic and are referred to as air pollutants [1]. These pollutants are in the ambient air in gas phase and are sorbed to aerosols. The fate, transport and removal of organic compounds from the atmosphere by dry and wet deposition processes are strongly influenced by their gases – particle partitioning [2]
