“…Hydrocarbon-contaminated soil containing toxic and persistent compounds pose harmful effects on the ecosystem [81,82]. Petroleum hydrocarbons are complex mixtures of diverse hydrocarbon compounds, including aliphatic saturated compounds or paraffins, such as straight and branched chain alkanes, cycloalkanes, unsaturated alkenes, and alkynes, as well as aromatic compounds such as polycyclic aromatic hydrocarbons (PAHs) and monoaromatic hydrocarbons (MAHs) such as BTEX (benzene, toluene, ethylbenzene, xylene), asphaltenes, resins, waxes and tars [48,83].…”

Soil water extracts could help to quickly assess the potential hazard of contaminants in soil, groundwater, and surrounding receiving water. In this study, the adverse effects of water extracts obtained from soils contaminated by heavy metals (sites A and B) or hydrocarbons (sites C, D and E) were evaluated using wheat, pak choi, and zebrafish. The test results obtained with freeze-dried soil samples showed a good correlation with those obtained from fresh wet soil samples. Phytotoxicity level was found to be greater in samples obtained from the metal-contaminated site B as compared to those from site A, whereas the opposite was observed for the zebrafish embryo acute toxicity. The water-soluble fractions of petroleum hydrocarbons in soils from sites C and D pose ecological risks to the environment, even though the concentrations of total petroleum hydrocarbon were below the established screening value. The results obtained with our battery of biological assays could complement the ecological risk estimation of a complex mixture of contaminants in soils. Site-specific ecological risk assessment using chemical analytical data, screening values, and ecotoxicity testing with soil water extracts could serve as a screening approach to identify the impact of contaminated soils on the freshwater environment.

“…It has evolved as a valuable strategy for optimizing all stages of site remediation, from site identification to project completion [21][22][23][24][25]. Technological screening is based on environmental and socioeconomic sustainability, and sustainable remediation projects require a thorough assessment of risk and site features [26][27][28]. In the European Union, there were around 2.8 million potentially contaminated sites in 2022 [29][30][31][32][33], highlighting the need for remediation due to its environmental, human health, and economic implications.…”

The European Union (EU) has placed a strong focus on soil contamination and remediation in its Thematic Strategy for Soil Protection, emphasizing the critical need for comprehensive soil data at the EU level. To effectively support EU soil management strategies, it is necessary to develop soil-related indicators and standardized datasets across all EU member states. However, the lack of standardized methodologies for estimating the time required for contaminated site remediation is a dilemma in Italy and throughout Europe. This study examines statistical data on the time-consuming nature of the contaminated site remediation process in Italy. In fact, early intervention not only simplifies site remediation but also reduces long-term financial obligations such as monitoring costs and potential legal implications. This study categorized data according to remedial procedures, explored different management phases, and revealed different timescales for completing the procedure. The findings show that processes completed after preliminary investigations are often shorter in time than those completed following conceptual model assessments. In contrast, processes that require corrective measures typically take a longer period of time to complete. Notably, remedial interventions tend to have a shorter duration compared to risk management interventions. Furthermore, procedures that address both soil and groundwater contamination generally require more time compared to those that focus only on soil remediation. This study provides valuable insight into the time-consuming aspects of remediation procedures, recommending potential changes to regulatory frameworks to accelerate site remediation activities.
