Bioremediation holds promise among various approaches to tackle oil spills in soils and sediments. In particular, using oil-degrading bacteria is an efficient and self-regulating way to remove oil spills. Using animals for oil spills remediation is in its infancy, mostly due to the lack of efficient oil-degrading capabilities in eukaryotes. Here we show that Caenorhabditis elegans nematodes survive for extended periods (up to 22 days) on pure crude oil diet. Moreover, we report for the first time the use of Alcanivorax borkumensis hydrocarbonoclastic bacteria for colonisation of C. elegans intestines, which allows for effective digestion of crude oil by the nematodes. The worms fed and colonised by A. borkumensis demonstrated the similar or even better longevity, resistance against oxidative and thermal stress and reproductivity as those animals fed with Escherichia coli bacteria (normal food). Importantly, A. borkumensis-carrying nematodes werThere has been a rapid increase in abandoned mines across China, Consequently, external-soil spray seeding technologies have emerged as a common method for their remediation. However, slope soils are typically unstable and easily collapsed and the nutrients absorbed by plants are insufficient, which complicate ecological restoration. For this study, we added mineral-solubilizing microbes and a water retaining agent to an external-soil spray seeding substrate in Lespedeza bicolor pots. We investigated the soil nutrients, soil enzyme activities, root growth parameters, root tensile properties, and root-reinforced soil shear strengths. The results revealed that the addition of microbes enhanced soil nutrients, soil enzyme activities, and the content of lignin and hemicellulose, which promoted root growth. Further, the addition of a water retaining agent promoted Lespedeza bicolor root growth but decreased the root tensile strength and force. Shear stress under the microbe treatment was more robust than without iBiogenic organic aerosols are important components of atmospheric organic aerosols and play vital roles in atmospheric chemistry, global climate, and biogeochemical cycles of carbon. However, studies on biogenic organic aerosols in the vast regions of the Southern Ocean and over the coastal waters of the Antarctic, especially Antarctic Peninsula, are still extremely limited. To understand the concentrations, molecular composition and seasonality of biogenic organic aerosols in Antarctica, atmospheric aerosols were collected at the Palmer Station on the west Antarctic Peninsula experiencing dramatic climate warming. Molecular marker compounds of fungal spores and secondary organic aerosols formed from the photooxidation of isoprene and monoterpene were analyzed using gas chromatography/mass spectrometry. Concentrations of sugar alcohols and biogenic SOA tracers both presented seasonal patterns with higher average concentrations in summer (90.7 and 122 pg m-3) than in winter (8.88 and 57.2 pg m-3). Sugar alcohoThe pollution of karst aquifers by acid mine drainage (AMD) waters is increasing. Major and minor ions (Ca2+, Mg2+, HCO3-, SO42-, F-, and Fe), stable sulfur and oxygen isotopes of dissolved sulfates (δ34SSO4 and δ18OSO4) and oxygen isotope of water (δ18OH2O), were analyzed in rainwater, surface water, groundwater, and AMD water sampled from the Babu subterranean stream watershed, in Southwest China. The principal aim of this study was to explore the impact of AMD waters on the evolution of karst aquifers. Based on hydrogeochemistry and stable isotopes (δ18OH2O, δ18OSO4 and δ34SSO4) (1) the chemistry of AMD waters was primarily controlled by pyrite oxidation, karst conduit water by AMD waters and mixing with calcite and dolomite dissolution, and spring water by atmospheric precipitation and carbonate dissolution; (2) contamination of the karst conduit water was mainly attributed to the input of AMD waters, resulting in a shift of δ34SSO4 towards more negative values (from 3.4‰ to -13.2‰); (3) the quality of kaAmbient fine particulate matter (PM2.5) data of similar continuously monitored species at two air monitoring sites with different characteristics within the City of Toronto were used to gauge the intra-city variations in the PM composition over a largely concurrent period spanning two years. One location was less then 8 m from the side of a major highway while the other was an urban background location. For the first time, multi-time resolution factor analysis was applied to dispersion-normalized concentrations to identify and quantify source contributions while reducing the influence of local meteorology. These factors were particulate sulphate (pSO4), particulate nitrate (pNO3), secondary organic aerosols (SOA), crustal matter (CrM) that were common to both sites, a hydrocarbon-like organic matter (HOM) exclusive to the urban background site, three black carbon related factors (BC, BC-HOM at the highway site, and a brown carbon rich factor (BC-BrC) at the urban background site), biomass burning organic matTo alleviate inhibition of anaerobic digestion caused by capsaicin, which is easily soluble in the lipid components of food waste (FW), an advanced oxidation process with sodium percarbonate/ultraviolet (SPC/UV) was used to generate free radicals for degrading capsaicin and recovering methane production. Free radical sweeping showed that the free radicals OH, O2- and CO3- worked together to degrade capsaicin. Gas chromatography-mass spectrometry showed that capsaicin likely had four degradation pathways via conversion into benzoquinone, and finally into carbon dioxide and water. The degradation rate of capsaicin in lipids increased from 62.2% to 96.0% when the SPC concentration increased from 2 mmol/L to 32 mmol/L (UV intensity = 20.66 mW/cm2). The degradation rate increased from 70.9% to 94.6% when the UV intensity increased from 20.66 mW/cm2 to 46.86 mW/cm2 (SPC concentration = 4 mmol/L). The subsequent products after capsaicin degradation were subjected to anaerobic digestion either directly or by adding FOrganisms in the marine environment are being exposed to an increasing variety of chemicals. This research presents an effect-based monitoring method for the derivation of a margin of safety for environmentally realistic chemical mixtures. The method is based on a combination of passive sampling and ecotoxicity testing. First, passive sampling was performed using H2O-philic divinylbenzene Speedisks during 3 sampling campaigns between 2016 and 2018 at 4 sampling locations in the Belgian part of the North Sea. Next, we exposed the marine diatom Phaeodactylum tricornutum to Speedisk extracts that were reconstituted in HPLC-grade water and defined the MoS of each sample as the highest no-observed effect concentration, expressed as relative enrichment factor (REF). A REF was defined by comparing the concentrations of 89 personal care products, pesticides and pharmaceuticals in the biotest medium with those measured in water grab samples to relate exposure concentrations in the tests to environmental concentrationsChanges in rhizodeposits of crops under elevated CO2 (eCO2) and elevated temperature (eT) may substantially impact on soil microbial community, which in turn affects soil carbon and nutrient cycling. However, the responses of soil bacterial community to long-term eCO2 and eT are not fully understood. A seven-year field experiment using open-top chambers was carried out with soybean (Glycine max L. Merr.) and maize (Zea mays L.) grown in a Mollisol soil under ambient CO2 (380 ppm), eT (2.1 °C increase in air temperature) and eTeCO2 (elevated temperature plus elevated CO2, 2.1 °C increase in air temperature and 700 ppm CO2). Soil DNA was extracted for Illumina MiSeq sequencing. The principal coordinate analysis showed that changes of bacterial community structure due to eT and eTeCO2 were greater in soybean- than maize-grown soils. The eT increased the relative abundances of Gaiella and Bacillus in Actinobacteria and Firmicutes, but decreased those of Nocardioides and H16 in Actinobacteria and Proteobacteria, rSoil has been identified as an important source of exposure to a variety of chemical and biological contaminants. Toxoplasma gondii is one of those potential biological contaminants associated with serious health effects in pregnant women and immunocompromised patients. Gardening or consumption of homegrown vegetables may present an important route of T. gondii infection via accidental ingestion of soil. In the Netherlands, there is quantitative information on the risk of T. gondii infection via meat products, but not on the risk of infection through soil. The objective of this study was to develop a quantitative microbial risk assessment (QMRA) model for estimating the risk associated with T. gondii exposure via accidental soil ingestion in the Netherlands. In order to obtain the needed information, a magnetic capture method for detection of T. gondii oocysts in soil samples was developed, and T. gondii DNA was detected using qPCR targeting the 529 bp repeat element. The method was shown to provide 95% probaThe anaerobic treatment of food wastes (FW) for resource recovery has been extensively studied. However, the information on the traits of functional genes and enzymes for substrates metabolisms and their associations with microbial community are little. In this study, the influences of eggshells conditioning on the substrates metabolism for volatile fatty acids production (VFAs) in the process of FW fermentation were investigated at genetic levels by using the metatranscriptomic approach. The obtained results suggested that the critical genes involved in the carbohydrate and protein metabolisms (i.e. pgmB, GPI, glsA, pyrB and etc.) were up-regulated in the eggshell-conditioned reactor, which were beneficial to the bioconversion of macromolecule organics during FW fermentation. Moreover, the functional genes related with the intermediate products metabolism (i.e. pyruvate acid, butanoate) also exhibited differential genetic expression levels, which resulted in the alteration of microbial metabolic pathways andUsing manure compost (MC) as a substitute for chemical fertilizer (CF) has been regarded as an effective strategy to promote sustainable crop production. The application of biochar in compost production could significantly mitigate the emission of gaseous pollutants and improve compost quality. However, comprehensive investigations of the environmental performance of crop production using CF, MC, and biochar-amended MC strategies are scarce. Therefore, in this study, wheat production using four fertilizer strategies, including CF, MC, and biochar-amended MC with biochar addition rates of 5% (MCB5) and 10% (MCB10), was comparatively assessed in terms of their environmental performance using the life cycle assessment (LCA) method. Compared to the CF strategy, the majority of midpoint impact categories and all assessed damage categories (except for human health and resources in MCB10) were mitigated using the compost strategies. Furthermore, as the biochar application rate increased, the biochar-amended MC stratFor the last forty-five years (from 1974 to present) ferroalloy production in Bagnolo Mella, Northern Italy, has generated particulate emissions enriched in potentially toxic metals and metalloids including arsenic (As), lead (Pb) and manganese (Mn). Of these, Mn is unique in that it has a significant background concentration and is seldom studied as a contaminant but is potentially a significant toxin derived from dusts regionally. Here we examine the distribution, redistribution, speciation and bioavailability of the Mn-contaminated top soils affected by atmospheric emissions adjacent to the ferroalloy plant. Four sites, variably located in the study area in terms of both distance and direction from the plant, were considered as representative of increasing levels of industrial influence. Soil profiles showed that metal concentrations (measured by X-ray fluorescence) varied considerably by location, i.e. higher in the sites closer to the plant and also at the surface level, although distributed throughout tWe are in unprecedented times with the ongoing COVID-19 pandemic. The pandemic has impacted public health, the economy and our society on a global scale. In addition, the impacts of COVID-19 permeate into our environment and wildlife as well. Here, we discuss the essential role of wastewater treatment and management during these times. A consequence of poor wastewater management is the discharge of untreated wastewater carrying infectious SARS-CoV-2 into natural water systems that are home to marine mammals. Here, we predict the susceptibility of marine mammal species using a modelling approach. We identified that many species of whale, dolphin and seal, as well as otters, are predicted to be highly susceptible to infection by the SARS-CoV-2 virus. In addition, geo-mapping highlights how current wastewater management in Alaska may lead to susceptible marine mammal populations being exposed to the virus. Localities such as Cold Bay, Naknek, Dillingham and Palmer may require additional treatment of their wastewCoastal cities face increasing natural disaster risks. Developing a green infrastructure network can reduce coastal vulnerability by connecting green spaces. Only a few researchers have examined practical guidelines for a green infrastructure network in coastal cities. Therefore, the purpose of this study is to build a green infrastructure network by integrating potential evacuation routes and green spaces in a coastal city. The Haeundae District in South Korea was chosen as the study site. We constructed a green infrastructure network using space syntax and GIS network analysis. The results of this study showed that first, we created an integrated green infrastructure network by building evacuation route networks and urban ecological networks. Second, we evaluated the evacuation function and flood risk. Finally, we proposed green infrastructure network planning for coastal disasters, including hub and corridor design. This study can contribute to establishing strategies to reduce vulnerability in coastal cities.
