Summary: This study analyzed human serum samples collected from the participants of the 2017 Beijing Chronic Disease and Risk Factor Surveillance and found that organochlorine pesticides and polycyclic aromatic hydrocarbons were widespread environmental contaminants. The most common contaminants were pentachlorophenol and pyrene. Suburb residents showed significantly higher levels of PAHs compared to urban residents. Exposure to certain contaminants like benzo(a)pyrene, phenanthrene, fluoranthene, Pyr, hexachlorobenzene, and pentachlorobenzene were associated with increased risk of hyperglycemia and hyperlipidemia. Some serum samples also showed elevated levels of harmful substances that were associated with health risks.

Summary: The study found a high detection rate of polycyclic aromatic hydrocarbons (PAHs) metabolites in children living in the Valencian Region of Spain, with exposure levels affected by factors such as province of residence, BMI, age, consumption of plastic-wrapped food, and dietary habits. Risk assessment showed that children's daily intake levels were within safe limits, and no potential non-cancer health risks due to PAH exposure were observed.

Summary: Using ultra-performance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS), this study identified the monohydroxyl metabolites of naphthalene, phenanthrene, pyrene, and 9-fluorenone in the urine of low-dose PAH-exposed individuals. The concentrations of these metabolites were monitored for 15 consecutive days, and the results showed that they were strongly correlated with their parent PAH exposure and may serve as potential biomarkers of PAH internal exposure at low doses. This study provides methodological and data support for further health risk studies involving internal exposure to PAHs and other organic pollutants.

Summary: This study analyzed eleven metabolites of PAHs in the urine of 110 lactating women in Spain, finding that naphthalene metabolites had the highest urinary levels. Statistical analysis showed that smoking status and ingestion of certain food groups were the main influencing factors on PAH exposure. Overall, the study did not reveal a significant health risk for Spanish women due to PAH exposure.

Summary: The study measured the levels of 16 PAHs in soft drinks and non-alcoholic beers using the MSPE/GC-MS method and assessed their health risks. The concentrations of 16 PAHs in soft drinks were 0.702 ppb (n-ary sumation 16PAH) and 0.196 ppb (n-ary sumation 8PAHs), while in non-alcoholic beers, they were 1.315 ppb (n-ary sumation 16PAH) and 0.288 ppb (n-ary sumation 8PAHs). The Monte Carlo simulation results showed that the THQ 95th percentiles for soft drinks were 9.497E-04 (adults) and 2.221E-03 (children), and for non-alcoholic beers, they were 3.341E-03 (children) and 1.430E-03 (adults).

Summary: This study measured the levels of 7 PBDE congeners and 11 PAHs in dust samples collected in kindergartens, workplaces, and cars in Zagreb, Croatia. The results showed a potential risk, especially for professional drivers, with PBDEs mass fractions ranging from 3.11-14.42. Toddlers are also more susceptible to higher risk despite spending less time in cars.

Summary: This study investigated the spatiotemporal distribution, source, and ecological risk of PAHs and SPAHs in surface sediments in Laizhou Bay. The results showed seasonal differences in concentrations of PAHs and SPAHs and a spatial distribution trend of estuary > coast > offshore. Combustion sources, including petroleum, coal, and biomass, were identified as the main contributors to PAHs and SPAHs. The risk level of PAHs was low-to-moderate, while SPAHs posed a moderate-to-high ecological risk.

Summary: The study found that the PAH4 concentrations in AGFS-smoked products were below the EU maximum limits, while those from the traditional Cabin and Chorkor kilns exceeded the limits, with Chorkor having the highest concentrations. Based on the average consumption frequency and quantities of Ghanaian adults, the potential carcinogenic risks were lowest in gas-smoked products and highest in products smoked using traditional methods.

Summary: This study determined the levels of PM2.5, PAHs, and NPAHs in Singapore from 2020 to 2021. The results showed a slightly higher concentration of PM2.5 compared to 2015, while the average PAH concentration decreased during the sampling period. NPAHs were detected for the first time in Singapore, and PAHs and NPAHs were mainly attributed to local vehicle emissions. Air masses from Indonesia and southern China were found to potentially influence the air pollution levels in Singapore.

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.
