Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: A strategy for the synthesis of dibenz-[a,j]-anthracenes (DBAs) from cyclohexa-2,5-diene-1-carboxylic acids is presented. The method involves sequential C-H olefination, cycloaddition, and decarboxylative aromatization, leading to regioselective ring formation and functional group introduction.

Summary: This study found that the (OH)-O-center dot formation plays a crucial role in the degradation of PAHs during redox fluctuations, with the content of active Fe species being a key factor. Oxygenation induces the transformation of these active Fe species, affecting subsequent redox processes and organic contaminant degradation.

Summary: This study examines the effects of biochar derived from sewage sludge (BCSSL) or sewage sludge/biomass (BCSSLW) on the persistence and bioavailability of polycyclic aromatic hydrocarbons (PAHs) in soils with different properties. The results show that the content of organic solvent extractable PAHs decreases when biochar is applied to the soils, depending on pH and feedstock. Similarly, the content of freely dissolved PAHs also decreases. The bioavailability and persistence of PAHs in the biochar-amended soils are closely related to the chemical properties of the soils, as indicated by the significant relationships between PAH content and pH, cation exchange capacity, available nutrients, and dissolved organic carbon.

Summary: This study investigates the chemical reactivity of a fullerene fragment with alkali metals using truxene as a model. The results demonstrate the dependence of core curvature on charge and alkali metal coordination. Additionally, the deprotonation process introduces aromaticity and pi-conjugation, resulting in changes in the optical properties.

Summary: This study analyzed the impact of replacing beef tallow with various vegetable oils and milk fat on the properties of beef burgers. The partial replacement led to changes in the fatty acid profile and reduced hardness of the burgers. Canola oil and the control group had the highest PAH content. Vegetable oil substitution also affected the color and oxidation stability of the burgers. Canola oil and linseed oil were the most susceptible to oxidation. The findings suggest that replacing beef tallow with vegetable oils can be a promising approach to control the PAH content in meat products.

Summary: This study investigated the degradation of petroleum hydrocarbons in soil using FeS@BC and FeS activated persulfate (PS). The results showed that the FeS@BC/PS system had a higher removal rate for total petroleum hydrocarbons, polycyclic aromatic hydrocarbons, and n-alkanes compared to the FeS/PS system. Radical quenching experiment and Electron Paramagnetic Resonance revealed that the dominant active substance is sulfate free radical produced by PS during activation. The FeS@BC/PS system has great potential for the remediation of petroleum-contaminated soil.

Summary: The study aimed to determine the impact of Cr(VI) on the structure of bacteria and fungi in soil, the modification of this effect by humic acids, and the response of Zea mays to Cr(VI). The pot experiment revealed that Cr(VI) significantly distorted the growth and development of Zea mays, but this toxic effect was neutralized by humic acids. Cr(VI) had a negative impact on the diversity and richness of bacteria and the ecophysiological diversity of fungi, which was mitigated by Zea mays and the application of humic acids.

Summary: The study found that pyrethroids have adverse effects on soil microorganisms and enzymatic activity, but the cultivation of maize can mitigate these effects. Pyrethroids stimulate the growth of organotrophic bacteria and actinomycetes, inhibit fungal growth, and reduce soil enzymatic activity. Cultivating maize improves soil enzymatic activity and microbial community, alleviating the impact of pyrethroids on soil biota.

Summary: One of the major challenges faced by contemporary agriculture is how to achieve better yields of crops and higher biomass in unfavorable environmental conditions. This study aimed to determine the effect of Cr(VI) on the net calorific value of Zea mays, assess its impact on soil enzymatic activity, and identify the effectiveness of compost and humic acids in alleviating Cr(VI) toxicity. The results showed that Cr(VI) reduced the energy obtained from plants by decreasing maize biomass and disturbing the biochemical balance of the soil.

Summary: The present study aimed to evaluate the impact of soil contamination with Cr(III) and Cr(VI) on the biomass of Avena sativa L. and investigate the remediation capacity of Avena sativa L. as well as the effects of these chromium species on soil enzyme activity and physicochemical properties. The results showed that Cr(VI) was more toxic than Cr(III), and Avena sativa L. exhibited better tolerance towards Cr(III) contamination. However, Avena sativa L. was not effective in phytoextraction of chromium from soil. Dehydrogenases were the most sensitive enzymes to soil contamination with Cr(III) and Cr(VI), while catalase was the least sensitive. Na(2)EDTA exacerbated the negative effects of both Cr(III) and Cr(VI) on the growth and development of Avena sativa L. and soil enzyme activity.

Summary: Sorbents are increasingly used in soil reclamation due to their ability to adsorb or absorb chemical pollutants. This research aims to determine the sensitivity of soil enzymes in Zea mays soil remediated with four sorbents. The study found that both VERVA diesel oil and VERVA 98 petrol had toxic effects on Zea mays, with diesel oil being more damaging to growth and enzyme activity. The results suggest that molecular sieve sorbents may be effective in remediating diesel oil-polluted soils.

Summary: The aim of this study was to investigate the impact of copper soil contamination on the trace element content of sunflower plants. The introduction of selected neutralizing substances into the soil was also examined for its potential to reduce the effect of copper on sunflower. The results showed that copper contamination significantly increased the copper content in the aerial parts and roots of sunflower, but adding mineral substances to the soil helped reduce copper levels in the aerial parts of sunflower.

Summary: Negative public sentiment towards bisphenol A (BPA) has led to interest in finding less toxic alternatives, such as bisphenol F (BPF) and bisphenol S (BPS). However, concerns about the safety of BPF and BPS arise due to their structural similarity to BPA. This study focuses on analyzing their toxicity and impact on soil microbiomes, enzyme activity, and plant growth.
