In the natural environment, the interactions of different types of nanoparticles (NPs) may alter their toxicity, thus masking their true environmental effects. This study investigated the toxicity of silver NPs (AgNPs) combined with hematite (HemNPs) or polystyrene (PsNPs) NPs toward the freshwater algae Chlamydomonas reinhardtii and …
Effects of hematite on the ARGs propagation. In this study, a series of experiments were performed to explore effects of hematite with different sizes (77 ± 8 and 803 ± 300 nm) and concentrations (0, 1, 5, 25, 50 and 100 mg/L) on the multi-resistant RP4 plasmid conjugation between P. putida KT2440 and E. coli O157: H7.
Augmented escape of nanostructures to the ecosystem has necessitated the comprehensive study of their impact, especially on plants. In the current study, hematite nanoparticles were prepared by employing garlic extract and checked for their cytogenetic effect on onion roots and germination characteristics of five agricultural crops (Vigna …
Effect of incorporating hematite on the properties of ultra-high performance concrete including nuclear radiation resistance. Author links open overlay panel Yajun Lv ... the energy produced by nuclear power plants mainly comes from nuclear fission [3]. Although nuclear power plants have the highest level of protective measures [4 ...
In this review, a framework is presented for predicting the effects of USSE development on plants and wildlife by linking disturbance types associated with USSE construction and operation to the traits and response strategies of species and guilds. Case studies from representative Desert Southwest species and guilds of conservation …
It was found that the amount of arsenic uptake into the roots and leaves of the corn plants was significantly reduced when the soil had been treated with hematite(19). Hematite was found to be 'immobilising' the arsenic, preventing uptake. ... An unrelated study looked into the effect of hematite presence on the rate of bacteria catalysed ...
Download scientific diagram | Effect of the hematite NP fertilizer delivered via a modified seed presoak method on the growth of different legumes. (a) Images of plants taken on day 30 of growth ...
In an oxidizing atmosphere, the thermal decomposition of pyrite proceeds through several stages: it typically begins with the formation of pyrrhotite (Fe 1−x S, x=0-2), followed by the production of magnetite (Fe 3 O 4) and hematite (Fe 2 O 3), with SO 2 being the primary gaseous product (Hu et al., 2006).In contrast, under weakly oxidizing …
Plants are an important component of ecosystems and can be used for the evaluation of overall fate, transport and exposure pathways of IO-NPs in the environment. In this …
Additionally, we identify substantial bias in simulating hematite abundance in dust aerosols with current soil mineralogy descriptions, underscoring the necessity for improved data sources. Encouragingly, the next-generation imaging spectroscopy remote sensing data hold promise for capturing the spatial variability of hematite.
To evaluate the effects of hematite (HMT) on the stabilization of PTEs, 1–5% (by weight) of HMT was added into a contaminated red soil amended with hydroxyapatite (HAP) to simulate naturally occurring Fe oxides. ... the reducible and oxidizable fractions are potentially bioavailable to plants, and the residual fraction is …
