Summary: This study analyzed the correlation between urinary metals, arsenic, and polycyclic aromatic hydrocarbons (PAHs) concentrations and chronic bronchitis. The results showed a positive association between seven types of PAHs and chronic bronchitis, as well as urinary cadmium and chronic bronchitis. No other metals or arsenic were correlated with chronic bronchitis.

Summary: This study analyzed the urinary metabolites of polycyclic aromatic hydrocarbons (PAH) and their association with chronic obstructive pulmonary disease (COPD). The results showed that the exposure to PAH was linked to increased COPD risk, particularly for certain metabolites such as 1-NAP and 2-NAP. This highlights the need for timely environmental regulation.

Summary: The palladium-catalyzed cyclotrimerization of ortho-silylaryl triflates is a well-established method for synthesizing polycyclic aromatic hydrocarbons with triphenylene cores. In the reaction of pyrene with o-silylaryl triflates, higher homologues with eight- and ten-membered rings were unexpectedly formed along with the trimer, and a protocol was developed to isolate all members of this series. This novel class of PAHs was thoroughly investigated using various techniques, including X-ray diffraction, UV/Vis and fluorescence spectroscopy, and theoretical calculations. A mechanistic proposal for the formation of all higher cyclooligomers was supported by density functional theory (DFT) calculations.

Summary: Polycyclic aromatic hydrocarbons (PAHs), particularly chrysene, have toxic effects on the liver by increasing relative liver weight and elevated serum ALT levels; the hepatotoxicity of chrysene is dependent on the aryl hydrocarbon receptor (AhR), while Nrf2 plays a crucial role in protecting against oxidative liver injury induced by chrysene.

Summary: Although the association between single PAHs exposure and telomere length has been studied, the relationship between mixed PAHs exposure and telomere length in the general population is still uncertain. This study analyzed 8 PAHs and their correlation with telomere length, finding that mixed PAHs exposure was negatively associated with telomere length. Specifically, 2-napthol and 2-fluorene concentrations showed a significant negative correlation with telomere length. These findings indicate that PAHs may have a negative impact on telomere length in the general population.

Summary: Coal tar pitch, a binder used in the production of anodes for aluminum electrolysis, contains PAHs. The incomplete combustion of PAHs during the baking process leads to emissions. Experimental tests were conducted to examine the effect of temperature and atmosphere on PAH emissions. The results showed that the addition of oxygen significantly reduced the emissions.

Summary: Oilfield-produced water (OPW) contains a complex mixture of toxic organic and inorganic compounds, including refractory polycyclic aromatic hydrocarbons (PAHs) and polyaromatic hydrocarbons such as BTEX, which have become a global concern. The treatment of OPW is challenging due to the presence of harmful pollutants combined with oil and the generation of recalcitrant by-products. This article critically reviews the feasibility of heterogeneous photocatalysis for OPW treatment, presents the nature and health implications of these compounds, and evaluates pilot and commercial-scale applications of photocatalysis in water treatment.

Summary: This study investigated the association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: The synergistic effects of trace sulfadiazine and cast-iron corrosion scales on the formation of disinfection by-products in drinking water distribution systems were investigated. The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway. The study highlights the importance of considering trace antibiotics pollution and corrosion scales in water sources for DBP control.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
