Fractionated Analysis of Petroleum Hydrocarbons: Planning of Bioremediation for Oil Contaminated Sites and Monitoring using Fractionated Analysis
Abstract
Mineral oil and mineral oil products are complex mixtures of thousands of single substances with significant differences with respect to their toxicity. Similar Total Petroleum Hydrocarbon concentrations may not be similar in terms of the risk they pose to a receptor. Thus, the determination of TPH concentration does not necessarily deliver concise information on risks to humans and the environment. Alternative methods separate petroleum hydrocarbons in fractions (e.g. aliphatic and aromatic fractions) which represent groups of substances with comparable structures and physico-chemical properties (e. g. solubility, boiling point, carbon range). Based on that information, fraction specific effects and toxicity predictions can be made. According to variable amounts of diverse fractions in mineral oils and mineral oil products, different toxicity of hydrocarbon mixtures can be expected at the same total hydrocarbon concentration. Furthermore, appropriate bioremediation actions can be taken. The aim of the project is the analysis of petroleum hydrocarbon contaminated sites by means of the fractionated analysis of petroleum hydrocarbons. In order to refine the evaluation of polluted sites, bioremediation of polluted sites will be accompanied by analytical and toxicological monitoring.
