“…Chemical micro-components of pollution are mainly represented by heavy metals, such as cadmium, lead, zinc, copper. These elements are indicators for changes in the ecological state of territories with contaminated soils and territories adjacent to them [14]. Photo from the website of the Ukrainian Nature Protection Group [12] Physical impact involves changing the physical parameters of the soil as a result of the use of weapons and military equipment.…”

Environmental damage to Ukraine from the full-scale aggression of the Russian Federation amounts to almost 2 trillion. hryvnias, some of the natural resources have been lost forever, the Minister of Environmental Protection and Natural Resources of Ukraine. In 2021, about 2 tons of toxic substances were released into the atmosphere. During the six months of the war in Ukraine in 2022, emissions into the atmosphere will amount to 46 million tons. The war poisoned a large part of the Ukrainian land. The damage caused by soil pollution is estimated at 18 billion dollars. According to the UN, Ukraine is one of the most mined countries in the world (almost 15% of the total area). Demining of this territory or detonation of mines will also lead to soil and groundwater contamination. During the explosion, fragments of projectiles containing impurities of cast iron, iron, carbon, sulfur and copper enter the environment and can lead to soil and underground water pollution. Mining of agricultural lands is a separate danger -soil contamination can lead to the fact that it will not be possible to grow anything in these territories for some time. And since we are an agrarian country and we are quite dependent on cultivation on our lands, this will also affect the food security of Ukraine and the world. Significant territories of Ukraine are polluted with organic substances in the composition of petroleum products, solvents, antifreeze, etc. These include paraffins, naphthenes, aromatic compounds (benzene, toluene, ethylbenzene, xylene), polycyclic hydrocarbons (naphthalene, perylene), halogenated hydrocarbons, dichloroethane, chloroform, chlorobenzene, organic solvents, surfactants, synthetic phenols, dioxins, and others. This happens during repairs, refueling of military equipment in the field, in places where fuel and lubricants are stored, during bursts of oil pipelines, hitting oil depots. Getting into the soil, these substances disrupt its structure and gas exchange processes, prevent the absorption of moisture, creating conditions unsuitable for the life of plants, animals, and microorganisms.

“…Furthermore, the intricate and systemic nature of site remediation necessitates a detailed analysis of how contaminants interact with remediation technologies, which is crucial for refining and enhancing the remediation process [18]. For instance, chemical reduction technology mainly applies to treating non-volatile organic pollutants, with their effectiveness hinging on pollutant properties and environmental conditions [7,19].…”

Screening remediation technologies through the lens of green, low-carbon, and sustainable development is crucial for contaminated land management. To better understand the applicability of remediation technologies, this paper explored their application in China based on a survey of 643 cases. By employing coupled analysis and local spatial autocorrelation methods, this study reveals the alignment between remediation technologies and pollutants, along with their spatial distribution and clustering patterns. Specifically, the four primary remediation technologies identified were cement kiln co-processing (CKCP), chemical oxidation/reduction (CO/CR), thermal desorption (TR), and solidification and stabilization (S/S), collectively accounting for over 90% of the cases. Additionally, our findings indicated significant variation in how different pollutants respond to remediation technologies, largely attributable to the characteristics of the pollutants. We observed High–High clustering patterns for CKCP, CO/CR, TR, and S/S. These were predominantly found in Jiangsu, Chongqing, Shandong, and Guizhou for CKCP and CO/CR and in Hebei, Jiangsu, Shanghai, and Chongqing for CO/CR. TR exhibited a High–High clustering in Shanghai, as did S/S. This research contributes to reducing the economic and resource costs associated with the trial-and-error of screening contaminated soil remediation technologies, offering valuable scientific and technological guidance for contaminated land regulation.

“…Areas where there is, or has been, strong industrial activity have been identified as key indicators for pollution increase and instability of ecosystems. This fact is not only related to the industrial activity they carry out but also to all the transport of raw materials and manufactured goods, like rail and port complexes associated with it, that promotes the formation of oil spill areas [2,26,27].…”

Microorganisms are ubiquitous in the biosphere, influenced by both their surrounding environment and the biotic and abiotic factors of ecosystems. Contaminated areas often harbor species adept at utilizing pollutants as nutrients, thus enhancing their resilience to environmental pressures. Identifying and characterizing these species can significantly benefit bioremediation processes. To contribute to this understanding, bioremediation experiments were conducted in Barreiro, a pivotal industrial hub in Portugal during the 20th century. Soil samples from two distinct locations were analyzed: one near Barreiro city, impacted by various anthropogenic activities leading to increased fuel pollutants and the other in a protected wooded area designated for recreational and educational purposes. All identified hydrocarbon-degrading microorganisms belonged to the Pseudomonas genus. Bioremediation assays isolated bacteria from pure colonies, compared with mixtures of all bacterial morphotypes capable of growth in the pollutant's presence. Consistently higher bioremediation rates for gasoline and toluene were observed using mixed cultures. Effective degradation-capable bacterial strains were identified in both locations, demonstrating bioremediation potential. Mixed bacterial cultures exhibited superior degradation rates, underscoring the importance of microbial diversity for bioremediation effectiveness. Also, the composition and bioremediate activity of microbial communities change in response to hydrocarbon concentration were analyzed, providing insights into the resilience of microbial communities to environmental stressors and their capacity to adapt to contaminated conditions. These findings emphasize the importance of in-depth, on-site investigations to elucidate the interplay between native microbial communities and pollutant degradation potential in soil.
