Plant and algal toxicity of persistent free radicals and reactive oxygen species generated by heating anthracene-contaminated soils from 100 to 600 °C

Abstract: Persistent free radicals (PFRs) are emerging contaminants of increasing concern, yet their formation, fate, toxicity and health risk are poorly known. Thermal treatment, a common remediation technique to clean industrial soils, induces the formation of PFRs, which could paradoxically increase soil toxicity, contrary to the original objective of remediation. Actually, there is little knowledge on the formation and toxicity of PFRs in soils contaminated by polycyclic aromatic hydrocarbons (PAHs). Here we studied… Show more

“…It is imperative to systematically study and discuss the possible adverse environmental effects of BC application concerning various media, including water and the atmosphere, by determining the corresponding occurrence, detection, assessment, and avoidance measures. Worryingly, the current knowledge concerning the possible adverse effects on the environment and biota deriving from the extensive application of PFRs originating in BC is even more limited [ 222 ]. Although they are emerging as contaminants of increasing concern, their formation, fate, toxicity, and health risks are poorly known [ 222 ].…”

“…The regulation of oxidative stress (OS) by the altered salinity is one of the environmental physiologies of major concern in animals [6,[19][20][21] (Figure 2 and Table 1). The outcome as OS is initiated by the oxidation of lipids, proteins, or nucleic acids caused by excessive production of reactive oxygen species (ROS), and studies on OS physiology play a paramount role in environmental chemistry [22][23][24][25][26][27] (Figure 2). Animals consume oxygen through internal respiration for oxidative phosphorylation to generate adenosine triphosphate (ATP).…”
