A major international effort has been made to monitor sun-induced chlorophyll fluorescence (SIF) from space as a proxy for the photosynthetic activity of terrestrial vegetation. However, the effect of spatial heterogeneity on the SIF retrievals from canopy radiance derived from images with medium and low spatial resolution remains uncharacterised. In images from forest and agricultural landscapes,

Biomass pyrolysis performance is improved through co-pyrolysis with hydrogen rich plastic producing more liquid fuel products of higher quality. Furthermore, beyond the synergetic effect, in catalytic pyrolysis the presence of plastic may facilitate the contact between catalyst and biomass. In this study, the effect of pretreatment of plastic/biomass was investigated, in order to further improve the

To initiate the experimental study of natural gas diffusion in sewage pipeline and evaluate the sewage pipeline risk, a new outdoor full-scale water cycling experimental pipeline system was built. The concentration distributions and characteristic time were measured in a comprehensive monitoring system. As the rate of the gas leakage flow decreases, the alarm time increases significantly. It is found

Due to complexities and uncertainties, risk management of domino effects in chemical plants in operation is challenging. A global optimal risk management scheme can hardly be obtained, therefore, finding a targeted local optimal risk management scheme can be prudent. In the present study, a novel risk management approach is proposed to reduce fire-induced domino effect risk by leveraging loading/unloading

Antimony (Sb), a toxic metalloid, exists mainly as Sb(V) and Sb(III) in the aquatic environment. Sb(V) displays greater solubility and can be reduced to insoluble Sb(III) compounds by microbial activities under anaerobic conditions, thus affecting the environmental fate of Sb. This study was conducted to evaluate the potential of Sb(V) reduction and removal from the aqueous phase by microbial communities

Brominated flame retardants (BFRs) can enter aquatic environments where they can have adverse effects on organisms. The BFR, 1,2,5,6-Tetrabromocyclooctane (TBCO), has been introduced as a potential replacement for the major use BRF, Hexabromocyclododecane (HBCD). However, little is known about effects of TBCO on aquatic organisms. Using zebrafish (Danio rerio) as a model species, objectives of this

We investigated the associations between refugee and environmental attitudes among 36876 respondents from 20 countries included in the European Social Survey Round 8 (2016). Three preregistered hypotheses were supported: (H1) there was a positive association between these attitudes across countries (meta-analytical partial correlation = .16), (H2) anti-immigration party voters held more negative environmental

Flood disasters have appeared more frequently in recent years because of climate change and urbanization, and Integrated Flood Risk Management (IFRM) has emerged as an effective method to reduce damage from these floods. This research studies IFRM methods in three aspects: flood risk identification of high-risk areas, flood risk assessment to quantify economic losses, and flood risk management to identify

The aquatic environment is the major recipient of wastes containing nanoparticles and other contaminants. Titanium dioxide nanoparticles (NPTiO2) are one of the most produced and used nanoparticle worldwide. This study investigated the toxicity of NPTiO2, as well as the toxicity interaction between NPTiO2 and lead (Pb), in response to genetic and biochemical biomarkers using freshwater fish Rhamdia

The effects of radiofrequency exposure on the health of people living near mobile-phone base stations (MPBSs) have been the subject of several studies since the mid-2000s, with contradictory results. We aimed to investigate the association between measured exposure to radiofrequency electromagnetic fields (RF-EMF) from MPBSs and the presence of self-reported non-specific and insomnia-like symptoms

Heat waves (HWs) and urban heat islands (UHIs) can potentially interact. The mechanisms behind their synergy are not fully disclosed. Starting from the localized UHI phenomenon, this study aims i) to reveal their associated impacts on human thermal comfort through three different definitions of HW events, based on air temperature (airT), wet-bulb globe temperature (WBGT) and human-perceived temperature

The plant community is the basic landscape unit of the coastal green space. The study of the oil-contaminated coastal green space plant community has an important role in improving the landscape quality and aesthetics of the coastal green space. This article takes the oil pollution shoreline of Jiaozhou Bay as an entry point to build a plant community landscape evaluation model, analyzes and evaluates

Studies reporting on associations between short-term exposure to outdoor fine (PM2.5), and ultrafine particles (UFP) and blood pressure and lung function have been inconsistent. Few studies have characterized exposure by personal monitoring, which especially for UFP may have resulted in substantial exposure measurement error. We investigated the association between 24-hour average personal UFP, PM2

New York City (NYC) experienced a sharp decline in air pollution during the COVID-19 shutdown period (March 15, 2020 to May 15, 2020)—albeit at high social and economic costs. It provided a unique opportunity to simulate a scenario in which the city-wide air quality improvement during the shutdown was sustained over the five-year period, 2021 through 2025, allowing us to estimate the potential public

Simulating allergenic tree pollen is important to protect sensitive population and to support bioaerosols monitoring effort. Using the regional air quality model GEM-MACH, a simulation was conducted adopting two new main hypotheses: 1) the use of vertical correlation concept to force the vertical dispersion (a method normally used in tracer data assimilation) and, 2) the use of a puff instead of a

Objective Individuals with exercise-induced bronchoconstriction (EIB) use ß2-agonists to reduce respiratory symptoms during acute exercise. The resulting bronchodilation could increase the dose of inhaled pollutants and impair respiratory function when exercise is performed in air pollution. We aimed to assess respiratory responses in individuals with EIB when completing a cycling bout while being

Liming acidic soils is often found to reduce their N2O emission due to lowered N2O/(N2O + N2) product ratio of denitrification. Some field experiments have shown the opposite effect, however, and the reason for this could be that liming stimulates nitrification-driven N2O production by enhancing nitrification rates, and by favoring ammonia oxidizing bacteria (AOB) over ammonia oxidizing archaea (AOA)

Air quality policies based on scientific and technical information are effective for controlling air pollution and protecting public health. Analysis of observations from periodic intensive field studies combined with updated emission inventories, air quality monitoring and numerical modeling can be used to address the causes that trigger air pollution and catalyze the design of cost-effective emissions

The Data Assimilation Research Testbed (DART) has been extended to be able to assimilate the column-average dry-air mole fraction of CO2 (XCO2) retrievals from the Orbiting Carbon Observatory 2 (OCO-2) satellite. Atmospheric CO2 concentrations over the Midwestern United States were estimated by the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem), with and without assimilating

Via combining aerosol vertical profiles from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) and assimilated multi-layer wind profiles from the Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2), the horizontal aerosol cross-boundary transport for the Edmonton-Calgary Corridor (ECC) during 2011–2017 was characterized on the basis of

Per‐ and polyfluoroalkyl substances (PFAS) have emerged as contaminants of environmental concern following release from industrial practices and use of Aqueous Film Forming Foam (AFFF). Of the identified PFAS in surface water samples from known AFFF release sites, perfluorooctanesulfonate (PFOS) and perfluorohexanesulfonic acid (PFHxS) are frequently detected. The focus of this study was to determine

Lead poisoning, mainly through incidental ingestion of lead ammunition in carcasses, is a threat to scavenging and predatory bird species worldwide. In Australia, shooting for animal control is widespread, and a range of native scavenging species are susceptible to lead exposure. However, the prevalence of lead exposure in Australia's scavenging and predatory birds is largely unknown. We evaluated

Nimbolide is a tetranortriterpenoid derived from the leaves and flowers of Azadirachta indica (Neem). It exhibits anticancer activity against a variety of cancers by modulating various crucial features, including cell proliferation, apoptosis, and invasion and metastasis. More importantly, the cytotoxic effect of nimbolide has also been observed against T cell lymphoma, but the underlying mechanisms

Cadmium (Cd) is an environmental toxicant and a nonessential metal. Cd can attack a wide range of organs, such as the liver, kidney, lung, ovary, testis, brain, and muscle in vertebrates. Among these organs, the testis might be the most sensitive organ to Cd toxicity. Metallothionein (MT) is a cysteine-rich protein with a low molecular weight, that can bind with Cd and eliminate reactive oxygen species
