[PMID]: 29431327 [Au] Autor: Donerian LG; Vodianova MA; Tarasova ZE [Ti] Título: [Microscopic soil fungi - bioindicators organisms contaminated soil]. [So] Source: Gig Sanit;95(9):891-4, 2016. [Is] ISSN: 0016-9900 [Cp] País de publicação: Russia (Federation) [La] Idioma: rus [Ab] Resumo: In the paper there are considered methodological issues for the evaluation of soil biota in terms of oil pollution. Experimental studies have shown that under the exposure of a various levels of oil pollution meeting certain gradations of the state and optimal alteration in microbocenosis in sod-podzolic soils, there is occurred a transformation of structure of the complex of micromycetes and the accumulation of toxic species, hardly typical for podzolic soils - primarily represantatives of the genus Aspergillus (A.niger and A. versicolor), Paecilomyces (P.variotii Bainer), Trichoderma (T.hamatum), the genus of phytopathogens Fusarium (F.oxysporum), dermatophytes of genus Sporothrix (S. schenckii) and dark-colored melanin containing fungi of Dematiaceae family. Besides that there are presented data on the study of microbiocenosis of the urban soil, the urban soil differed from the zone soil, but shaped in similar landscape and climatic conditions, and therefore having a tendency to a similar response from the side of microorganisms inhabiting the soil. Isolated complex of soil microscopic fungi is described by many authors as a complex, characteristic for soils of megalopolises. This allowed authors of this work to suggest that in urban soils the gain in the occurrence of pathogenic species micromycetes also increases against a background of chronic, continuously renewed inflow of petroleum hydrocarbons from various sources of pollution. Because changes in the species composition of micromycetes occurred in accordance with the increasing load of oil, so far as microscopic soil fungi can be recommended as a bioindicator organisms for oil. In the article there is also provided information about the distinctive features of modern DNA identification method of soil microscopic fungi and accepted in our country methodology of isolation of micromycetes with the use of a nutrient Czapek medium.

[Ti] Título: Chitinophaga humicola sp. nov., isolated from oil-contaminated soil. [So] Source: Int J Syst Evol Microbiol;68(3):751-757, 2018 Mar. [Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: A yellow-coloured, Gram-stain-negative, non-motile, aerobic and rod-shaped bacterium, designated strain Ktm-2 , was isolated from oil-contaminated soil. Strain Ktm-2 was able to grow at 15 to 40 °C, pH 4.5-10.0 and 0-2 % (w/v) NaCl concentration. This strain was taxonomically characterized by a polyphasic approach. Based on the 16S rRNA gene sequence analysis, strain Ktm-2 represented a member of the genus Chitinophaga and shared highest sequence similarity with Chitinophaga barathri YLT18 (98.1 %), Chitinophaga cymbidii R156-2 (96.4 %) and Chitinophaga niabensis JS13-10 (96.3 %). The only respiratory quinone was menaqunone-7, the major polar lipid was phosphatidylethanolamine and the predominant fatty acids were iso-C15 : 0, C16 : 1ω5c and iso-C17 : 0 3-OH. The DNA G+C content was 52.1 mol%. The DNA-DNA relatedness between strain Ktm-2 and C. barathri YLT18 was 22.0 %, which falls below the threshold value of 70 % for the strain to be considered a novel species. The morphological, physiological, chemotaxonomic and phylogenetic analyses clearly distinguished this strain from its closest phylogenetic neighbours. Thus, strain Ktm-2 represents a novel species of the genus Chitinophaga, for which the name Chitinophagahumicola sp. nov. is proposed. The type strain is Ktm-2 (=KEMB 9005-693 =KACC 19388 =JCM 32158 ).

[Ti] Título: Tritonibacter horizontis gen. nov., sp. nov., a member of the Rhodobacteraceae, isolated from the Deepwater Horizon oil spill. [So] Source: Int J Syst Evol Microbiol;68(3):736-744, 2018 Mar. [Is] ISSN: 1466-5034 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: A heterotrophic, Gram-stain-negative, aerobic, sodium-requiring and motile bacterium was isolated from oil-contaminated surface water of the Gulf of Mexico during the Deepwater Horizon oil spill. Strain O3.65 showed highest 16S rRNA gene sequence similarity to Phaeobacter gallaeciensis BS107 and Phaeobacter inhibens T5 , both with 98.3 %, respectively. Based on complete genome analysis, highest similarity was observed to species of the genus Ruegeria. Strain O3.65 exhibited a broad salinity, temperature and pH range of 0.5-10 % NaCl, 4-45 °C and 5.5-9.0, respectively. The DNA G+C content of strain O3.65 was 61.5 mol%. The major respiratory lipoquinone was ubiquinone-10 (Q-10), the most dominant fatty acids (>1 %) comprised 18 : 1ω7c and 18 : 1ω7c 11-methyl, 10 : 0 3OH, 12 : 1 3OH, 14 : 1 3OH/3-oxo-14 : 0, 16 : 0, 16 : 0 2OH, 18 : 1 2OH and 12 : 1. The polar lipid pattern indicated presence of phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid, two unidentified phospholipids and seven unidentified lipids. On Difco marine broth agar, strain O3.65 formed smooth, shiny white to beige and convex colonies with regular edges. Phylogenetic, phylogenomic and phenotypic differences revealed that strain O3.65 represents a new species of a novel genus within the family Rhodobacteraceae, for which we propose the name Tritonibacter horizontis gen. nov., sp. nov. The type strain of the type species is O3.65 (=DSM 101689 =LMG 29740 ).

[Ti] Título: In situ sodium persulfate/calcium peroxide oxidation in remediation of TPH-contaminated soil in 3D-sand box. [So] Source: Environ Technol;39(1):91-101, 2018 Jan. [Is] ISSN: 0959-3330 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The aim of this article was to obtain the application parameters and conditions of in situ sodium persulfate/calcium peroxide oxidation. For the purposes of remediation, soil from a total petroleum hydrocarbons (TPH)-contaminated site was collected and prepared to reflect the actual stratum condition in a newly developed soil remediation modeling apparatus. Application methods of soil mixture, natural infiltration, direct injection and groundwater circulation were used to simulate in situ sodium persulfate oxidation in TPH-contaminated soil. Results showed that the transfer capability of Na S O in simulated soil was strong Na S O migrated to the saturated layer after 3 days of in situ injection, which then continued both horizontal and vertical migration. After 7 days the oxidant was widespread in the saturated layer with a radius of influence of 0.4 m. It was found that mixing CaO /Fe /CA with soil and spraying Na S O can effectively repair the surface-contaminated soil, and the longitudinal migration of Na S O in the reaction process can further strengthen the remediation of the upper layer soil. Due to the buffering effect of the soil, the effect of oxidation on the pH and temperature of different soil layers was small, but detectable in comparison to natural environmental factors.

[Ti] Título: Toxicological and thermoregulatory effects of feather contamination with artificially weathered MC 252 oil in western sandpipers (Calidris mauri). [So] Source: Ecotoxicol Environ Saf;146:118-128, 2017 Dec. [Is] ISSN: 1090-2414 [Cp] País de publicação: Netherlands [La] Idioma: eng [Ab] Resumo: The external contamination of bird feathers with crude oil might have effects on feather structure and thus on thermoregulation. We tested the thermoregulatory ability of western sandpipers (Calidris mauri) in a respirometry chamber with oil applied either immediately prior, or three days before the experiment. The birds were then exposed to a sliding cold temperature challenge between 27°C and -3°C to calculate thermal conductance. After the experiment, a large blood sample was taken and the liver extracted to measure a range of parameters linked to toxicology and oxidative stress. No differences in thermal conductance were observed among groups, but birds exposed to oil for three days had reduced body temperatures and lost more body mass during that period. At necropsy, oiled birds showed a decrease in plasma albumin and sodium, and an increase in urea. This is reflective of dysfunction in the kidney at the loop of Henle. Birds, especially when exposed to the oil for three days, showed signs of oxidative stress and oxidative damage. These results show that the ingestion of externally applied oil through preening or drinking can cause toxic effects even in low doses, while we did not detect a direct effect of the external oil on thermoregulation over the temperature range tested.

[So] Source: J Environ Sci (China);64:197-206, 2018 Feb. [Is] ISSN: 1001-0742 [Cp] País de publicação: Netherlands [La] Idioma: eng [Ab] Resumo: Soil contamination by diesel has been often reported as a result of accidental spillage, leakage and inappropriate use. Surfactant-enhanced soil flushing is a common remediation technique for soils contaminated by hydrophobic organic chemicals. In this study, soil flushing with linear alkylbenzene sulfonates (LAS, an anionic surfactant) was conducted for intact columns (15cm in diameter and 12cm in length) of diesel-contaminated farmland purple soil aged for one year in the field. Dynamics of colloid concentration in column outflow during flushing, diesel removal rate and resulting soil macroporosity change by flushing were analyzed. Removal rate of n-alkanes (representing the diesel) varied with the depth of the topsoil in the range of 14%-96% while the n-alkanes present at low concentrations in the subsoil were completely removed by LAS-enhanced flushing. Much higher colloid concentrations and larger colloid sizes were observed during LAS flushing in column outflow compared to water flushing. The X-ray micro-computed tomography analysis of flushed and unflushed soil cores showed that the proportion of fine macropores (30-250µm in diameter) was reduced significantly by LAS flushing treatment. This phenomenon can be attributed to enhanced clogging of fine macropores by colloids which exhibited higher concentration due to better dispersion by LAS. It can be inferred from this study that the application of LAS-enhanced flushing technique in the purple soil region should be cautious regarding the possibility of rapid colloid-associated contaminant transport via preferential pathways in the subsurface and the clogging of water-conducting soil pores.

[Ti] Título: Exertional heat illness and acute injury related to ambient wet bulb globe temperature. [So] Source: Am J Ind Med;59(12):1169-1176, 2016 Dec. [Is] ISSN: 1097-0274 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: BACKGROUND: The Deepwater Horizon disaster cleanup effort provided an opportunity to examine the effects of ambient thermal conditions on exertional heat illness (EHI) and acute injury (AI). METHODS: The outcomes were daily person-based frequencies of EHI and AI. Exposures were maximum estimated WBGT (WBGTmax) and severity. Previous day's cumulative effect was assessed by introducing previous day's WBGTmax into the model. RESULTS: EHI and AI were higher in workers exposed above a WBGTmax of 20°C (RR 1.40 and RR 1.06/°C, respectively). Exposures above 28°C-WBGTmax on the day of the EHI and/or the day before were associated with higher risk of EHI due to an interaction between previous day's environmental conditions and the current day (RRs from 1.0-10.4). CONCLUSIONS: The risk for EHI and AI were higher with increasing WBGTmax. There was evidence of a cumulative effect from the prior day's WBGTmax for EHI. Am. J. Ind.

[Ti] Título: Application of solidifiers for oil spill containment: A review. [So] Source: Chemosphere;194:837-846, 2018 Mar. [Is] ISSN: 1879-1298 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The need for new and/or improvement of existing oil spill remediation measures has increased substantially amidst growing public concern with the increased transportation of unconventional crudes, such as diluted bitumen products. Solidifiers may be a very good spill response measure to contain and mitigate the effects of oil discharge incidents, as these interact with the oil to limit hydrocarbon release into air and water, prevent it from adhering onto sediment and debris, and could allow for oil recovery and reuse. Solidifiers change the physical state of the spilled oil from liquid to a coherent mass by chemical interactions between the spilled oil and the solidifier. Currently, the use of solidifiers is limited to small spills near shorelines. To extend their use to large-scale spill containment operations, it is necessary to understand the mechanism of solidifier action and to establish consistent criteria for evaluation of their effectiveness. The research effort to date has been focused mainly on gelators and cross-linking agents, with particularly impressive advancements in the areas of phase-selective polymeric and small-molecule gelators. Substantial research efforts are needed to improve solidifier performance and integrate solidifiers as part of spill response procedures, particularly for acute oil spills involving unconventional petroleum products.

Electronic address: konstantinos.kotzakoulakis@gmail.com. [Ti] Título: Predicting the weathering of fuel and oil spills: A diffusion-limited evaporation model. [So] Source: Chemosphere;190:442-453, 2018 Jan. [Is] ISSN: 1879-1298 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The majority of the evaporation models currently available in the literature for the prediction of oil spill weathering do not take into account diffusion-limited mass transport and the formation of a concentration gradient in the oil phase. The altered surface concentration of the spill caused by diffusion-limited transport leads to a slower evaporation rate compared to the predictions of diffusion-agnostic evaporation models. The model presented in this study incorporates a diffusive layer in the oil phase and predicts the diffusion-limited evaporation rate. The information required is the composition of the fluid from gas chromatography or alternatively the distillation data. If the density or a single viscosity measurement is available the accuracy of the predictions is higher. Environmental conditions such as water temperature, air pressure and wind velocity are taken into account. The model was tested with synthetic mixtures, petroleum fuels and crude oils with initial viscosities ranging from 2 to 13,000 cSt. The tested temperatures varied from 0 °C to 23.4 °C and wind velocities from 0.3 to 3.8 m/s. The average absolute deviation (AAD) of the diffusion-limited model ranged between 1.62% and 24.87%. In comparison, the AAD of a diffusion-agnostic model ranged between 2.34% and 136.62% against the same tested fluids.

[Ti] Título: Development of a field testing protocol for identifying Deepwater Horizon oil spill residues trapped near Gulf of Mexico beaches. [So] Source: PLoS One;13(1):e0190508, 2018. [Is] ISSN: 1932-6203 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: The Deepwater Horizon (DWH) accident, one of the largest oil spills in U.S. history, contaminated several beaches located along the Gulf of Mexico (GOM) shoreline. The residues from the spill still continue to be deposited on some of these beaches. Methods to track and monitor the fate of these residues require approaches that can differentiate the DWH residues from other types of petroleum residues. This is because, historically, the crude oil released from sources such as natural seeps and anthropogenic discharges have also deposited other types of petroleum residues on GOM beaches. Therefore, identifying the origin of these residues is critical for developing effective management strategies for monitoring the long-term environmental impacts of the DWH oil spill. Advanced fingerprinting methods that are currently used for identifying the source of oil spill residues require detailed laboratory studies, which can be cost-prohibitive. Also, most agencies typically use untrained workers or volunteers to conduct shoreline monitoring surveys and these worker will not have access to advanced laboratory facilities. Furthermore, it is impractical to routinely fingerprint large volumes of samples that are collected after a major oil spill event, such as the DWH spill. In this study, we propose a simple field testing protocol that can identify DWH oil spill residues based on their unique physical characteristics. The robustness of the method is demonstrated by testing a variety of oil spill samples, and the results are verified by characterizing the samples using advanced chemical fingerprinting methods. The verification data show that the method yields results that are consistent with the results derived from advanced fingerprinting methods. The proposed protocol is a reliable, cost-effective, practical field approach for differentiating DWH residues from other types of petroleum residues.
