Abstract:
... Microplastic accumulation in the lake aquatic environment has attracted worldwide attention, but the long-term deposition characteristics and influencing factors of microplastics are not clear. Hence, we attempted to analyze the factors that influence the accumulation of microplastics during the process of natural environmental change and social development through the method of the sedimentologic ...

Abstract:
... Over the past decades, the plastic production has been dramatically increased. Indeed, a category of small plastic particles mainly with the shapes of fragments, fibers, or spheres, called microplastics (particles smaller than 5 mm) and nanoplastics (particles smaller than 1 µm) have attracted particular attention. Because of its wide distribution in the environment and potential adverse effects t ...

Abstract:
... Microplastics could accumulate and enrich antibiotics in the aquatic environment. Despite this, the joint effects of microplastics and antibiotics on aquatic organisms are not clear. Here, we investigated the changes of microbial interactions in both gill and gut of marine medaka exposed to polystyrene microbeads (PS) and/or tetracycline for 30 days by using co-occurrence network analysis based on ...

Abstract:
... Perfluoroalkyl acid (PFAA) pollution of freshwaters has attracted a great deal of attention and poses a challenge to the restoration of river ecosystems. However, detailed studies on the impact of PFAAs and their alternatives on microbial plankton communities are lacking, and few studies have examined the adaptability of those communities to PFAAs. In this study, water samples were obtained from w ...
... Psychoactive substances have been identified as a kind of emerging contaminants in aquatic environment and pose potential adverse effects on aquatic animals. Yangtze finless porpoise, a critically endangered species in China, is also facing the threat of psychoactive substances. In this study, the accumulation characteristics and risk prioritization of psychoactive substances were investigated in ...

Abstract:
... The temporal and spatial characteristics of urban river bacterial communities help us understand the feedback mechanism of bacteria to changes in the aquatic environment. The Fuhe River plays an important role in determining the water ecological environment of Baiyangdian Lake. 16S rRNA gene sequencing was used to study the microbial distribution characteristics in the Fuhe River in different seas ...
aquaticenvironment, etc ; Anthropocene epoch; nanoplastics; Show all 3 Subjects
Abstract:
... Microplastic research has become a buzz word. It is seen as one of the most pressing issues of Anthropocene contamination. There is certainly no doubt about the ubiquitous presence of microplastic (MP) in almost all environmental matrices. However, the validity of considering them as a vector for contaminants needs some reconsideration, there are other more potent pathways. Their effect on marine ...

Abstract:
... The gravity of the impending threats posed by microplastics (MPs) pollution in the environment cannot be over-emphasized. Several research studies continue to stress how important it is to curb the proliferation of these small plastic particles with different physical and chemical properties, especially in aquatic environments. While several works on how to monitor, detect and remove MPs from the ...

Abstract:
... Environmental behavior and ecotoxicity of microplastics (MPs) are significantly influenced by the omnipresent self-assembly of microbial extracellular polymeric substances (EPS) on them. However, mechanisms of EPS self-assembly onto MPs at nanoscale resolution and effects of aging are unclear. For the first time, temporospatial nano-heterogeneity of self-assembly of EPS onto fresh and one-year age ...

Abstract:
... Research has shown the effort to develop conceptual models that relate anthropic stressors to changes in aquatic environment state. Several of these models come from the structure Drivers, Pressures, State, Impact and Response (DPSIR), which has been used since the 1990s. However, there is a lack of conceptual models that consider in its structure the connection between the damages caused in the a ...

Abstract:
... The scientific understanding regarding sources, occurrence, and effects of microplastics in the aquatic environment has advanced rapidly, leaving some meaningful knowledge gaps virtually untouched. One of them is the interactions of microplastics and biofilms, microbial communities ubiquitous in aquatic ecosystems and fundamental for a range of ecosystem‐level processes. It is evident that biofilm ...

Abstract:
... Sulfonamides have attracted special attention due to their widespread use and refractory nature in the aquatic environment. Heterogeneous catalytic peroxymonosulfate (PMS) activation for sulfonamide degradation has been demonstrated to be an encouraging strategy. Herein, ultrathin nickel aluminium layered double hydroxide (U–NiAl-LDH) was employed as an efficient peroxymonosulfate activator. The a ...

Abstract:
... Microplastics, an emerging contaminant, is ubiquitous in almost every compartment of the environment. They are of great environmental concern not only due to their pervasive, persistent, and toxic nature but also due to their ability to act as carriers of toxic metals, microbes, pesticides, etc. Comprehensive knowledge of the transport and degradation pathways of microplastics through water bodies ...

Abstract:
... The occurrence of emerging contaminants (ECs), such as pharmaceuticals and personal care products (PPCPs), perfluoroalkyl and polyfluoroalkyl substances (PFASs) and endocrine-disrupting chemicals (EDCs) in aquatic environments represent a major threat to water resources due to their potential risks to the ecosystem and humans even at trace levels. Mathematical modelling can be a useful tool as a c ...

Abstract:
... Microplastics (MPs) are ubiquitous in aquatic environments, which are important carriers of emerging contaminants (ECs). Biofilms can be attached to the surface of MPs in a natural aquatic environment, which may influence chemical adsorption; however, knowledge of its impact is still limited. This study investigated the effect of biofilms on MPs on the adsorption of ECs through field-laboratory ex ...

Abstract:
... Amphiops mater Sharp, 1873, live on the water surface from the egg stage to the pupal stage. Pupae are usually attached to floating objects and normally hatch even when removed from the objects and allowed to float on the water. The pupal period lasts 2–3 days (mean 2.4 days). Interestingly, the pupae are not easily preyed upon by water striders, Gerris latiabdominis Miyamoto, 1958, and their inco ...
