Remediation of diesel-contaminated soil enhanced with firefighting foam application

Abstract

During rescue operations related to the elimination of the effects of industrial accidents or natural disasters, extinguishing agents are used that affect the migration and transformation of contamination in the environment. Firefighting foam sprayed onto an oil spill slowly drains to an aqueous solution and penetrates the soil. The role of surfactants in the removal of petroleum derivatives is well known, but such extinguishing agents also contain solvents, preservatives, corrosion inhibitors and other ingredients that can reduce the beneficial effect of surfactants on soil remediation. The article presents the results of research on the remediation of soil contaminated with diesel fuel and enhanced with firefighting agents used to extinguish fires or remove oil spills on the road. The obtained results of biodegradation and leaching studies indicate differences in the efficiency of diesel fuel removal from soils. It was also found that Wet 1% reduces the amount of polycyclic aromatic hydrocarbons (PAHs) in the soil compared to oily samples not wetted with extinguishing solutions. Chromatographic analyses have shown both the hydrocarbons degradation and the possibility of their transformation into more hazardous compounds. The effectiveness of soil remediation depends on the chemical composition of the extinguishing agent used on the contaminated soil.

Reducing the intensity of thermal radiation at the sublayer extinguishing of alcohols by ecologically acceptable aerosols

“…Thus, works [12,13] show that many manufacturers of foaming agents indicate that their products are environmentally friendly and quickly decompose in the environment. However, despite such claims, the authors of the cited work indicate that almost all products cause irreparable harm to the environment.…”

Applicability of Ash Wastes for Reducing Trace Element Content in Zea mays L. Grown in Eco-Diesel Contaminated Soil

“…Among the large group of xenobiotics released into the environment, petroleum derivatives are particularly dangerous, especially given continuing industrial development and the rising demand for fuel [ 1 , 2 ]. Diesel oil is a highly problematic pollutant, as it contains multiple toxic carcinogens and teratogens, which differ in their chemical structure and biodegradability.…”

“…Diesel oil also has a high potential for migration and uncontrolled spread in the environment [ 3 , 4 ]. Compared to other petroleum derivatives, diesel oil is slower to evaporate and decompose [ 2 ], posing a challenge for environmental engineering.…”

Biodiversidad bacteriana presente en suelos contaminados con hidrocarburos para realizar biorremediación

“…Así, una herramienta muy útil para solucionar este problema es la biorremediación, la cual permite restaurar suelos o aguas contaminadas, siendo esta técnica una alternativa biotecnológica muy interesante. Dicha técnica utiliza microorganismos con capacidad de biodegradar hidrocarburos como fuente de energía para su crecimiento y desarrollo (Rakowska, 2020).…”
