Abstract:
... Toxic heavy metal ions, valuable noble metal ions and organic dyes are significant concerns in wastewater treatment. In this work, MoO₃ nanobelts (MoO₃ NBs) prepared by solvothermal method and MoS₂ nanoarrays (MoS₂ NAs) constructed using MoO₃ NBs precursor were proposed to effectively remove heavy/noble metal ions and organic dyes, such as Pb⁽ᴵᴵ⁾, Au⁽ᴵᴵᴵ⁾ and Methylene Blue (MB). The two adsorbent ...

Abstract:
... Organic electroactive compounds can be applied as alternative cathodes in rechargeable zinc ion batteries (ZIBs) instead of using inorganic cathode materials with low stability or high toxicity. However, many reported organic ZIB cathodes have some limitations, which are their tedious synthesis processes and low yields. In this work, perylene diimide-ethylenediamine/carbon black (PDI-EDA/CB) compo ...

Abstract:
... Microplastics (MPs) have been identified as a threat to global ecosystems. Current projections indicate that the negative impacts of MPs will increase in the environment. Traditional toxicity testing does not account for the diversity of MP particles, the inherent diversity in potential exposure routes, and complex impacts in exposed organisms. Here we present and discuss factors influencing organ ...

Abstract:
... The method of quenching was adopted to reduce the emission of PCDD/Fs from a pilot scrap preheated EAF. Because quenching can effectively inhibit the de novo synthesis of dioxins. Meanwhile the temperatures at the inlet and outlet of the quenching part of EAF off-gas were measured to investigate the quenching effect. The results show that the temperatures of the off-gas are quenched from about 130 ...

Abstract:
... Infectious and parasitic agents have been frequently associated with debilitating and wasting conditions in sheep. The prevalence of these agents has probably undermined the role of toxic causes as contributors to such disorders. In addition, many of these intoxications frequently produce acute clinical disease with specific and characteristic lesions, thus a causal relationship with the toxic sub ...

Although amitraz is one of the acaricides most commonly applied within beehives, to date, its time-dependent oral toxicity in honeybees has not been investigated, due to amitraz’s instability in aqueous media. In aqueous media such as honey, amitraz rapidly forms a continuously changing tertiary mixture with two of its major hydrolysis products, DMF and DMPF. The contribution of each hydrolysis pr ...

Abstract:
... Abiotic oxidation of toxic As(III) to As(V) is being deemed as a necessary step for the overall arsenic decontamination in both natural and engineered systems. Direct oxidation of As(III) by chemical oxidants, such as ozone, permanganate, ferrate, chlorine and chloramine, or naturally occurring minerals like Mn, Fe oxides, seems straightforward. Both O₂ and H₂O₂ are ineffective for arsenite oxidat ...
