Both steps of each ozonolysis reaction are examined here using a high-level computational chemistry approach (DF-HF/DF-LCCSD(T)-F12a//B3LYP/aug-cc-pVTZ), and a rate constant and product branching ratio are produced for each reaction. The reactions are then categorized into broadly defined taxonomic groups on the basis of how the ozonolysis chemistry is affected by functional groups, steric bulk and the spatial arrangement of the substituent groups. The five alkene taxonomic groups used for classification are monosubstituted alkenes, trisubstituted alkenes, <em>E</em>-2-alkenes, <em>Z</em>-2-alkenes and haloalkenes. The general cycloaddition reactivity trend identified for these alkene groups is <em>k</em><small>_THEO</small> (haloalkenes) &lt; <em>k</em><small>_THEO</small> (monosubstituted alkenes) &lt; <em>k</em><small>_THEO</small> (<em>E</em>-2-alkenes) ∼ <em>k</em><small>_THEO</small> (<em>Z</em>-2-alkenes) &lt; <em>k</em><small>_THEO</small> (trisubstituted alkenes). Within these categories, one secondary trend was that if one or more substituents was small and rich in hyperconjugative α-H atoms, such as a methyl group, a higher alkene rate and a higher CI yield would be induced, compared to a bulky and α-H-poor substituent, such as a <em>tert</em>-butyl (<small>^<em>t</em></small>Bu) group. Furthermore, bulky or electronegative substituents were also shown to prompt a reduction in <em>syn</em>-CI yields. Also highlighted in the study is the theoretical mechanism of how the ozonolysis of haloalkenes generates significant yields of tropospheric CF<small>₃</small>CHO, a species which can undergo photolysis to produce the strong greenhouse gas fluoroform (CHF<small>₃</small>).</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

This study investigated the synthesis and application of a magnetic graphene oxide calcium alginate composite (MGO@CA) for rapid removal of lead (Pb<small>²⁺</small>) ions from aqueous systems, demonstrating its effectiveness through various adsorption studies and characterisation techniques. We utilised XRD, FTIR, VSM, and SEM to confirm the structural and magnetic properties of the MGO@CA composite, while BET and AFM analyses were performed to assess its surface area and roughness, which are essential for evaluating its adsorption capacity. Characterization results indicated the formation of a composite with functional groups of both graphene oxide and alginate and a rough surface, high surface area, and magnetic properties. The adsorption process was optimised by studying the effect of varying solution pH, adsorbent dosage, contact time, and initial lead concentration. The maximum adsorption capacity for Pb<small>²⁺</small> ions was determined to be 270.27 mg g<small>⁻¹</small>, as revealed using the Langmuir isotherm model, indicating the high efficiency of the composite in removing lead from water. Different adsorption isotherms and reaction kinetic models were studied for the adsorption process. The obtained adsorption data fit well with both the Langmuir and Freundlich adsorption isotherms, indicating the heterogeneous surface of the composite containing sites with different affinities for Pb<small>²⁺</small>. The adsorption process followed pseudo-second-order reaction kinetics. Furthermore, the adsorbent is regenerable and reusable, maintaining 82.28% of its initial adsorption capacity after 5 cycles.

An intriguing and promising substitute for the chemical practice of shielding plants against the growing hazards of these pathogens lies in biological plant protection. This approach focuses on using biological control agents (BCAs) using microbial-based biocontrol techniques to inhibit the growth of phytopathogens responsible for plant diseases. Microbial BCAs interact with pathogens or plant hosts to increase their resistance, which may be a useful way to control the development of agricultural diseases. However, in comparison to a single strain, microbial consortia with distinct modes of action might exhibit a multifunctional and more resilient effect as a biocontrol. The market is currently offering only a small number of microbial consortia-based biocontrol interventions as these products are still in their infancy of development and demand substantial research to avert phyto-parasitic nematodes. The employment of BCAs to combat phytopathogens will become an increasingly vital component of sustainable agriculture in the future. Thus, this article provides a thorough review of the current status of bacteria and fungi and their microbial consortia-based biocontrol for plant protection research through a biological manner considering upcoming and advanced technological developments. Commercialization of biocontrol products and associated challenges and ways to overcome these hurdles are also discussed as future perspectives. The present review also summarizes the latest research done (particularly the past five years' data) on the activity of BCAs bacteria, fungi and their consortium against various plant pathogens with their enormous benefits for upgrading plant growth and defense mechanisms.

To support the geographical diversification of REE sources, there is a need for a comprehensive documentation of REE content and, by extension, the economic potential of fly ash derived from Nigeria's vast coal fields. Eight representative coal fly ash samples generated from coals from Nigeria's major coal belts were collected. Silica and alumina, with respective ranges of 38.1–44.5% and 14–15.98%, accounted for the bulk of the major elements in the samples. Total REE contents in the samples ranged from 874 ppm to 1127 ppm, while the cerium, yttrium, neodymium and lanthanum-dominated rare oxide totals were found to be in the range of 941–2145 ppm across the samples. The outlook coefficients (extractability indices) computed for the samples ranged between 0.8 and 1.3, with 0.7 as the benchmark. The range of percentage of critical REEs in the CFA samples was 28%–36%.

Prolonged droughts lower groundwater levels and reduce soil moisture that elevates the risk of wildfires, which can contaminate water resources and damage water supply infrastructure. This case study examines the impact of wildfires on water quality in porous volcanic strata in the Arctic. The primary water extraction area for the capital region of Iceland supplies drinking water to six municipalities, representing approximately 64% of the country's population. The water source is mainly located in a postglacial porous lava field with thin volcanic strata and limited surface water. On May 4th, 2021, a large wildfire occurred in the watershed following a prolonged drought, burning 56.5 hectares of land. Three of the water intake zones for the capital region are situated 300 meters to a few kilometres from the fire-affected area. Water quality monitoring data from these zones, covering the period 2011–2023 and comprising 47 samples (28 pre-fire and 19 post-fire), were analysed. The results show the presence of polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs), as well as an increase in certain metals after the wildfire. The total concentration of the five detected PAHs ranged from 1.1 to 7.3 ng l<small>⁻¹</small>, with PAHs detected up to five months post-wildfire. These were predominantly five- or six-ring carcinogenic PAHs, though levels remained well below the parametric values set by Icelandic drinking water regulations. Some VOCs were also detected after the wildfire, albeit mostly at a later stage. Additionally, several metals were found in concentrations up to nearly six times higher than the median values recorded from 2011 to 2020. These findings suggest that groundwater quality is vulnerable to contamination following wildfires, underscoring a critical knowledge gap regarding the impacts of climate change on the water sector and the need for enhanced risk mitigation strategies.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

The nanoparticles were synthesized using an extract from <em>Acacia nilotica</em> leaves, which acted as a stabilizing and reducing agent. The characteristics of the synthesized nanoparticles were analyzed using various techniques including UV-visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray photoelectron spectroscopy. The pot experiment utilized a salinity level of 50 mM NaCl and tested five concentrations of ZnO NPs (0, 25, 50, 75 and 100 ppm). The results demonstrated that the highest concentration (100 ppm) significantly enhanced growth parameters, including the shoot length (38.6%) and root length (25.5%) compared to the control. Additionally, biochemical parameters such as chlorophyll content (23.3%) and phenolic content (12.5%) enhanced zinc accumulation by 38.7% and decreased oxidative stress malondialdehyde (MDA) by 54.4% and hydrogen peroxide (H<small>₂</small>O<small>₂</small>) by 33.1% as compared to the control.
