“…Around 20 papers were concerned with human physical and mental health. Several studies investigated how extreme events might result in toxic levels of pollution and the possible impacts on human health (e.g., Pedersen et al, 2008;Li et al, 2010;Vanos et al, 2015). Through a combined literature review and geographic information systems (GIS) analysis, Plumlee et al (2016) evaluated the impacts that an ARKStorm-a hypothetical but realistic "megastorm" scenario for California-could have on environmental contamination.…”

Extreme events in biological, societal, and earth sciences: A systematic review of the literature

The term “extreme event” is commonly used to describe high-impact, unanticipated natural events, like floods, tsunamis, earthquakes, and volcanic eruptions. It first appeared in the scientific literature in the 1950s and has since spread to disciplines as diverse as economics, psychology, medicine, and engineering. The term is increasingly being applied to the study of historical, prehistorical, and deep-time events across a broad range of scales, and it is widely acknowledged that such events have had profound impacts on the Earth’s biodiversity and cultures. Understandably, then, how people think about, define, and study extreme events varies considerably. With extreme events expected to become more frequent, longer lasting, and more intense in the coming decades as a result of global warming, the differing extreme event definitions—both across and within disciplines—is likely to lead to confusion among researchers and pose significant challenges for predicting and preparing for extreme events and their impacts on natural and social systems. With this in mind, we conducted a systematic quantitative review of 200 randomly selected, peer-reviewed “extreme event” research papers (sourced from Web of Science, accessed January 2020) from the biological, societal, and earth sciences literature with the aim of quantifying several pertinent features of the research sample. On the one hand, our analysis found a great deal of variability among extreme event papers with respect to research interests, themes, concepts, and definitions. On the other hand, we found a number of key similarities in how researchers think about and study extreme events. One similarity we encountered was that researchers tend to view extreme events within a particular temporal context and quite often in terms of rates of change. Another similarity we encountered was that researchers often think of and study extreme events in terms of risks, vulnerabilities, and impacts. The similarities identified here may be useful in developing a common and comprehensive definition of what constitutes an extreme event, and should allow for more comparative research into extreme events at all spatio-temporal scales which, we predict, will provide important new insights into the nature of extreme events.

“…However, both aniline and TNT are characterized by high toxicity, difficult removal, environmental accumulation, bioaccumulation, and carcinogenicity [6]. Moreover, they are prone to accumulating in soil and groundwater environment [7], thereby posing threats to both the ecological environment and human health [8,9]. As a result, these issues have garnered significant attention from countries around the world [10,11].…”

The transport of mobile colloidal particles with organic pollutants in porous media has attracted considerable attention. Aniline and 2,4,6-trinitrotoluene (TNT), as aromatic compounds and key components of energetic materials, are continuously released into the environment. This study compared the co-transport of loess colloidal particles with aniline and TNT, aiming to investigate the influence of structural and physicochemical properties of the pollutants. The colloids were prepared and characterized, and static adsorption and dynamic column experiments were conducted. The results indicate that the adsorption processes of aniline and TNT both conformed to the quasi-second-order kinetic and the intra-particle diffusion models, with aniline exhibiting higher rate constants than TNT. The main adsorption mechanism involved van der Waals force, hydrogen bonding, and electrostatic interaction. Response surface experiments indicated that the adsorption capacity increased with higher initial concentration of organic compound but decreased with larger particle size and higher Na+ concentration. In column experiments, the adsorption of loess colloid particles on aniline and TNT was strongly correlated with the concentration of loess colloid particles. Loess colloid particles could be used as carriers to enhance the co-transport, with aniline exhibiting a faster transport rate due to the differences in polarity and molecular structure compared to TNT. In summary, loess colloidal particles enhanced the transport behavior of aniline and TNT in saturated loess columns. The differences in polarity and molecular structure of aniline and TNT further affect their co-transport mechanism in loess.

“…Nitroaromatic compounds (NACs) such as nitrobenzene (NB) were essential products and raw materials in industrial production. − Due to modern urban and industrial development, the concentration of NB in wastewater exceeded 35 mg/L . The persistent toxicity, carcinogenicity, and widespread distribution of NB in wastewater had led to serious environmental problems. − Therefore, it was crucial to effectively treat wastewater containing NB . It was generally recognized that the strong electron-absorbing nitro group of NB led to the poor efficiency of direct oxidative biological degradation. , However, the reduction products of NB were easily mineralized through oxidation processes. , In most biological degradation strategies, the reduction of NB was a crucial step in pollutant treatment process because its reduction products were more easily degraded by oxidation. , However, the catalytic efficiency of traditional biological methods for NB reduction was limited by the strong biological toxicity of NB and its reduction intermediates. , …”
