According to the literature, there are increasingly more scientific data regarding the environmental pollution of selenium(Se) and the boron(B). The purpose of this review is to give an overview of environmental pollutants for Se andB and the use of plants to alleviate worldwide problems associated with Se and B toxicity. Selenium is an essential element for many species, plant, as well as humans, but it is toxic at higher levels. Boron is relatively soluble in water and commonly causes environmental problems, especially for surface waters where most of the discarded B will end up. Using phytoremediation plants can address this problem. To prevent Se and B toxicity due to excess environmental Se or B, plants may be used to phytoremediate to take up Se and B from soil or water. Research in the past decades had provided a riches ofknowledge regarding the mechanisms by which plants uptake, metabolize, and accumulate Se or B.  Moreover, environment studies have revealed the important effects for plantsuptake of Se or B and interactions with herbivores, pollinators, neighbouring vegetation.

The article presents a comprehensive assessment of the geoecological risk of the Belaya River floodplain (Republic of Bashkortostan, Russia). The risk assessment of the floodplain-channel complex includes the risk of depletion by the plant species composition and the risk of depletion of the ecological and hydrological states. Geographic information maps of the floodplain were compiled for vegetation and floodplain forests and wetlands. The extent of forest cover was chosen as an indicator of the floodplain’s resilience to the risk of depletion and decline. The calculation of the risk of depletion of floodplains based on the ecological and hydrological state was carried out taking into account the changes in floodplain areas over the past 10 years, data on the catchment of ground and surface waters, “sealed” areas and the annual average discharge. The assessment and zoning of the river floodplain territory was carried out according to the proposed method.

While geologists are still considering whether the Anthropocene should be accepted as a formal geological epoch, it is up to us humanists to search for ways making this human era a good one. In this article, I will examine how we can use historical research to provide such tracks based on past regularities or similarities. Positive success stories from the past can at least provide faith that we can do something about our current environmental problems. This investigation is based on two case studies: the Tesla Model S electric car, and the Swedish pulp and paper industry's transition to chlorine-free bleaching. It argues that the sustainability revolution doesn't just share similarities with the quality movement of the 1970s and 1980s, but is essentially a continuation of it. In concordance with previous megatrends, the major benefit of the sustainability revolution will be reaped by countries and companies running ahead of the curve. A new term, 'trail-blazer dependency' is introduced; by setting an example, the first-movers are opening a trail for late-comers to follow.

The outbreak of the SARS-CoV-2-induced Coronavirus Disease 2019 (COVID-19) pandemic started in December 2019 in Wuhan, China, continued to spread across the globe and spanned 188 countries. Under the new circumstances treatment approach for T2 allergic diseases such as asthma, chronic hives, atopic dermatitis, and sinusitis with polyps has been changed. In the past years, new biological therapies monoclonal antibodies for these diseases have been developed targeting different aspects of the type 2 immune response. New knowledge on the COVID-19 disease course raises many issues around the safety of biologicals in patients with active infection, as well as their interactions with antiviral medications. In Russia new biological therapies entered clinical practice but its effectiveness and safety still are not known. This newsletter is based on Considerations on Biologicals for Patients with allergic disease in times of the COVID-19 pandemic: an EAACI Statement and the latest scientific data.

Abstract A large-ensemble climate simulation database, which is known as the database for policy decision-making for future climate changes (d4PDF), was designed for climate change risk assessments. Since the completion of the first set of climate simulations in 2015, the database has been growing continuously. It contains the results of ensemble simulations conducted over a total of thousands years respectively for past and future climates using high-resolution global (60 km horizontal mesh) and regional (20 km mesh) atmospheric models. Several sets of future climate simulations are available, in which global mean surface air temperatures are forced to be higher by 4 K, 2 K, and 1.5 K relative to preindustrial levels. Nonwarming past climate simulations are incorporated in d4PDF along with the past climate simulations. The total data volume is approximately 2 petabytes. The atmospheric models satisfactorily simulate the past climate in terms of climatology, natural variations, and extreme events such as heavy precipitation and tropical cyclones. In addition, data users can obtain statistically significant changes in mean states or weather and climate extremes of interest between the past and future climates via a simple arithmetic computation without any statistical assumptions. The database is helpful in understanding future changes in climate states and in attributing past climate events to global warming. Impact assessment studies for climate changes have concurrently been performed in various research areas such as natural hazard, hydrology, civil engineering, agriculture, health, and insurance. The database has now become essential for promoting climate and risk assessment studies and for devising climate adaptation policies. Moreover, it has helped in establishing an interdisciplinary research community on global warming across Japan.

In recent decades, environmental pollution has become a significant international public problem in developing and developed nations. Various regions of the USA are experiencing illnesses related to environmental pollution. This study aims to investigate the association of four environmental pollutants, including particulate matter (PM2.5), carbon monoxide (CO), Nitrogen dioxide (NO2), and Ozone (O3), with daily cases and deaths resulting from SARS-CoV-2 infection in five regions of the USA, Los Angeles, New Mexico, New York, Ohio, and Florida. The daily basis concentrations of PM2.5, CO, NO2, and O3 were documented from two metrological websites. Data were obtained from the date of the appearance of the first case of (SARS-CoV-2) in the five regions of the USA from 13 March to 31 December 2020. Regionally (Los Angeles, New Mexico, New York, Ohio, and Florida), the number of cases and deaths increased significantly along with increasing levels of PM2.5, CO, NO2 and O3 (p < 0.05), respectively. The Poisson regression results further depicted that, for each 1 unit increase in PM2.5, CO, NO2 and O3 levels, the number of SARS-CoV-2 infections significantly increased by 0.1%, 14.8%, 1.1%, and 0.1%, respectively; for each 1 unit increase in CO, NO2, and O3 levels, the number of deaths significantly increased by 4.2%, 3.4%, and 1.5%, respectively. These empirical estimates demonstrate an association between the environmental pollutants PM2.5, CO, NO2, and O3 and SARS-CoV-2 infections, showing that they contribute to the incidence of daily cases and daily deaths in the five different regions of the USA. These findings can inform health policy decisions about combatting the COVID-19 pandemic outbreak in these USA regions and internationally by supporting a reduction in environmental pollution.

Human-induced biodiversity decline has been on the rise for the past 250 years, due to various causes. What is equally troubling, is that we are unaware which plants are threatened and where they occur. Thus, we are far from reaching Aichi Biodiversity Target 2, i.e., assessing the extinction risk of most species. To that end, based on an extensive occurrence dataset, we performed an extinction risk assessment according to the IUCN Criteria A and B for all the endemic plant taxa occurring in Greece, one of the most biodiverse countries in Europe, in a phylogenetically-informed framework and identified the areas needing conservation prioritization. Several of the Greek endemics are threatened with extinction and fourteen endemics need to be prioritized, as they are evolutionary distinct and globally endangered. Mt. Gramos is identified as the most important conservation hotspot in Greece. However, a significant portion of the identified conservation hotspots is not included in any designated Greek protected area, meaning that the Greek protected areas network might need to be at least partially redesigned. In the Anthropocene era, where climate and land-use change are projected to alter biodiversity patterns and may force many species to extinction, our assessment provides the baseline for future conservation research, ecosystem services maintenance, and might prove crucial for the timely, systematic and effective aversion of plant extinctions in Greece.

Concerns have been raised to navigational safety worldwide because of the increasing throughput and the passing ships during the past decades while maritime accidents such as collisions, groundings, overturns, oil-spills and fires have occurred, causing serious consequences. Formal Safety Assessment (FSA) has been acknowledged to be a framework widely used in maritime risk assessment. Under this framework, this paper discusses certain existing challenges when an effective safety assessment is carried out under a variety of uncertainties. Some theories and methodologies are proposed to overcome the present challenges, e.g., Fault/Event Tree Analysis (FTA/ETA), Evidential Reasoning (ER), Bayesian Belief Network (BBN) and Belief Rule Base (BRB). Subsequently, three typical case studies that have been carried out in the Yangtze River are introduced to illustrate the general application of those approaches. These examples aim to demonstrate how advanced methodologies can facilitate navigational risk assessment under high uncertainties.
