Real time monitoring of soil contamination with diesel fuel using photoionization detectors

Abstract

Soil contamination is a very relevant environmental problem, which is directly connected with both groundwater and air contamination. Petroleum products represent often a major source of soil contamination. In this sense, leakage of diesel fuel can cause important environmental problems due to the persistence of it in contaminated soils and to its toxicity at low concentrations. Photoionization detectors (PID) have the ability to evaluate the ampleness of contamination by detection and quantification in real time of diesel fuel vapours. Finally, this achievement can lead to a rapid evaluation (in minutes) of soil contamination and will facilitate the application of most suitable remediation technologies. The purpose of this study was to simulate an accidental spill of diesel on the ground, with the aim to monitor the degree of volatilization of chemical compounds during six weeks. Thus, the reasons behind the low volatility of diesel fuel in the investigated soil samples, based on the trend of volatilization and on soil characteristics as well. ARTICLE HISTORY

Hunting for Toxic Industrial Chemicals: Real-Time Detection of Carbon Disulfide Traces by Means of Ion Mobility Spectrometry

“…We demonstrated through this study that IMS instrumentation is perfectly fitted for this type of application, presenting some strategic advantages (sensitivity, sensibility, and real-time response) compared with other techniques used before. Unspecific PID (photoionization detector) instrumentation, previously used for toxic VOCs monitoring in shoe shops [ 49 ] or soil contamination control [ 50 ], is also a suitable and useful technique to be used for quantification of CS 2 . The limits of detection of both PID and IMS are lower than the limits detected by the classically used instrumentation, while sample preparation is not required.…”

Sorption behaviour of xylene isomers on biochar from a range of feedstock

“…3 (Yu et al, 2012), and rice husk activated carbon with sorption capacity of 23.15 mg/g for p-xylene (Yakout, 2014). This range of sorption capacity can be sufficient to demonstrate biochar applications to control VOC emissions from contaminated soils, for example, according to real monitoring of volatile vapours from hydrocarbon contaminated soils (Bocos-Bintintan et al, 2019). The concentrations of VOCs emitted from crude oil contaminated lands highly depend on various factors controlled by the type of host soil, crude oil composition, environmental conditions, and history of contamination (Tran et al, 2018).…”

Sensing Precursors of Illegal Drugs—Rapid Detection of Acetic Anhydride Vapors at Trace Levels Using Photoionization Detection and Ion Mobility Spectrometry

“…The built-in sampling pump has an internal flow of 400 cm 3 min −1 and the instrument may be operated between −10 and +40 • C. Data logged into the internal microprocessor can easily be transferred to the PC computer using a COM connection cable and the associated software ProRAE Suite, ver. 3.01a, 2004 [24][25][26][27].…”
