“…The group of species with high hydrocarbon oxidizing activity includes 18 strains of microfungi: Alternaria alternata, Fusarium oxysporum, F. solani, Penicillium canescens st. 1, st. 2, st. 3, P. commune , P. decumbens , P. implicatum , P. jensenii st. 1, P. miczynskii st. 1, P. nigricans , P. ochrochloron , P. restrictum , P. simplicissimum st. 1, st. 2, P. velutinum , and Ulocladium consortiale . Among these, in terms of species diversity, the genus Penicillium prevailed, the representatives of which are also resistant to other types of pollution [ 42 , 43 ].…”

The Effectiveness of Biostimulation, Bioaugmentation and Sorption-Biological Treatment of Soil Contaminated with Petroleum Products in the Russian Subarctic

et al. 2021

The effectiveness of different bioremediation methods (biostimulation, bioaugmentation, the sorption-biological method) for the restoration of soil contaminated with petroleum products in the Russian Subarctic has been studied. The object of the study includes soil contaminated for 20 years with petroleum products. By laboratory experiment, we established five types of microfungi that most intensively decompose petroleum hydrocarbons: Penicillium canescens st. 1, Penicillium simplicissimum st. 1, Penicillum commune, Penicillium ochrochloron, and Penicillium restrictum. One day after the start of the experiment, 6 to 18% of the hydrocarbons decomposed: at 3 days, this was 16 to 49%; at 7 days, 40 to 73%; and at 10 days, 71 to 87%. Penicillium commune exhibited the greatest degrading activity throughout the experiment. For soils of light granulometric composition with a low content of organic matter, a more effective method of bioremediation is sorption-biological treatment using peat or granulated activated carbon: the content of hydrocarbons decreased by an average of 65%, which is 2.5 times more effective than without treatment. The sorbent not only binds hydrocarbons and their toxic metabolites but is also a carrier for hydrocarbon-oxidizing microorganisms and prevents nutrient leaching from the soil. High efficiency was noted due to the biostimulation of the native hydrocarbon-oxidizing microfungi and bacteria by mineral fertilizers and liming. An increase in the number of microfungi, bacteria and dehydrogenase activity indicate the presence of a certain microbial potential of the soil and the ability of the hydrocarbons to produce biochemical oxidation. The use of the considered methods of bioremediation will improve the ecological state of the contaminated area and further the gradual restoration of biodiversity.

“…For instance, exposure to fluoride pollution, a plant toxin, is a significant concern, and has been shown to decline significantly following closure of an aluminum smelter (Brougham et al, 2013a). Studies have also indicated significant growth of pathogenic fungi (Evdokimova et al, 2013a) and changes in soil composition around aluminum smelters (Evdokimova et al, 2013b, 2013c). Studies of Beluga whales that washed up dead near an aluminum refinery in Quebec, Canada, found elevated rates of cancer (Martineau et al, 2002).…”

Green Criminology and Social Justice: A Reexamination of the Lynemouth Plant Closing and the Political Economic Causes of Environmental and Social Injustice

Pamela Ann Davies argues that the closure of the Lynemouth, UK, aluminum smelter generated adverse social justice impacts and was caused by the adoption of green state policies. She employs that argument to critique green criminology for promoting adverse social justice impacts. Here, we reanalyze the Lynemouth plant closure. First, this reanalysis illustrates the various social and environmental forms of injustice the plant generated, especially its adverse human, nonhuman and ecological health consequences. Second, the closure is reassessed from a political economic perspective that places the plant closure within the context of global capitalist plant closures in the aluminum industry. That review notes that plant closures and deindustrialization in developed economies are now a common occurrence driven by economic concerns, not environmental policies. We point out that social injustice as well as ecological destruction are often created by the normal operation of capitalism, and that those consequences should not be overlooked.

Decomposition of birch leaves in heavily polluted industrial barrens: relative importance of leaf quality and site of exposure

The decrease in litter decomposition rate in polluted habitats is well documented, but the factors that explain the observed variation in the magnitude of this pollution effect on litter decomposition remain poorly understood. We explored effects of environmental conditions and leaf quality on decomposition rate of mountain birch (Betula pubescens ssp. czerepanovii) leaves in a heavily polluted industrial barren near the nickel-copper smelter at Monchegorsk. Litter bags filled with leaves collected from two heavily polluted barren sites and from two control forest sites were buried at 2.5-cm depth and exposed for 2 and 4 years at each of these four sites. The relative mass loss of native leaves in the industrial barren during 2 years of exposure was reduced to 49% of the loss observed in the unpolluted forest. We found a similar reduction in mass loss when leaves from control sites were exposed to polluted sites and when leaves from polluted sites were exposed to control sites. We conclude that the reduction in leaf litter decomposition in an industrial barren is caused by pollution-induced changes in both environmental conditions and leaf quality. This reduction is much smaller than expected, given the four-fold decrease in soil microbial activity and nearly complete extinction of saprophagous invertebrates in the polluted soil. We suggest that a longer snowless period and higher spring and summer temperatures at the barren sites have partially counterbalanced the adverse effects caused by the toxicity of metal pollutants.
