Crude Oil Contaminated Sites: Evaluation by Using Risk Assessment Approach

Abstract

Soils contaminated with toxic and persistent pollutants pose different and serious hazards to the environment and human health. Multidisciplinary procedures that are considering models for the prediction of risk for long-term exposure are needed. The present paper illustrates the operating mode and utility of an environmental software able toe0) integrates the dose-response modeling as a major part of hazard characterization in order to assess the quantitative risk from carcinogens. In this way, risk assessment is used as a method for the investigation of contaminated sites. The method is demonstrated on a Romanian field site, contaminated with petroleum products. For the assessment of human health risks from oil-contaminated sites, the contaminants of concern are considered as polycyclic aromatic hydrocarbons (PAHs), monocyclic aromatic hydrocarbons (MAHs), and heavy metals, chemicals known as human carcinogens. Quantitative risk calculations revealed an individual risk of 1.07 × 10 −5 for children and 6.89 × 10 −6 for adults. The paper represents a utility example of an environmental software solution that could be considered by decision-making factors in approving certain projects. The software tool is helpful for protecting the environment and human health.

The Impact of Biosurfactants on Microbial Cell Properties Leading to Hydrocarbon Bioavailability Increase

“…As a consequence, the transport and processing of crude oil and its derivatives is one of the large-scale industry branches [1][2][3]. The inevitable consequence is the high risk of the natural environment contamination with petroleum compounds [4]. Pollution caused by many various hydrocarbon substances has become an urgent environmental problem.…”

Decontamination of Petroleum-Contaminated Soils Using The Electrochemical Technique: Remediation Degree and Energy Consumption

“…Clearly, the hydrocarbons that are most absorbed and adsorbed by the organic matter in the soil are the most resistant to losses or alterations by other processes. By contrast, volatile hydrocarbons (soluble) are susceptible to changes due to volatilization, filtration and biodegradation 9 .…”

Characterisation of used traction sand for utilization aspects in earth construction based on the requirements of Finnish environmental legislation

“…To determine the concentrations of benzene and the cumulative content of TEX-compounds (toluene, ethylbenzene, xylene) in the traction sand, a modified ISO 22155 standard was used (Cocârţă et al 2017). In this procedure, the sample (20 g) was extracted with methanol (10 mL; including internal standard) for 30 minutes in orbital shaker.…”
