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 that the combination of Eisenia fetida and rhamnolipid JBR-425 with a bacterial consortium resulted in increased degradation levels of polycyclic aromatic hydrocarbons (PAH) from oil-contaminated soil. The bacterial consortium degraded 30-89% of selected PAH after 45 days, with chrysene showing the highest degradation (89%) and benzo(a)pyrene the lowest (30%). The earthworm biomass decreased and mortality rates increased with increasing crude oil concentrations, but a 100% survival rate was observed at 1% crude oil exposure, indicating the potential for bioremediation. The combination of E. fetida with the bacterial consortium showed better degradation of PAH, while rhamnolipid JBR-425 coupled with the consortium resulted in significant degradation as well. Overall, the application of the bacterial consortium in conjunction with E. fetida has great potential for the restoration of contaminated soil and ecosystem sustainability.

Summary: Olive oil and olive pomace, as main components of the Mediterranean diet, contain phenolic compounds that contribute to various health benefits. These compounds, such as oleuropein, tyrosol, and hydroxytyrosol, are believed to prevent and control diseases like cardiovascular diseases and cancer. However, olives and their products can be contaminated by mycotoxins, pesticide residues, and polycyclic aromatic hydrocarbons. Phenolic compounds in olive oil and pomace can reduce the toxicity of these contaminants, but the pollutants may also affect the beneficial properties of these products. Further studies are needed to understand the interactions between bioactive and toxic compounds in olive oil and pomace for a better understanding of their health benefits.

Summary: The presence of PAHs in parks poses a threat to human health, especially when ingested through different pathways. The environmental quality of parks directly affects the health of both tourists and residents. This study in Urumqi, Northwest China, analyzed PAHs content in park soil and common plants in eight typical parks. Results showed that PAHs content in park soil was 5-6 times higher in the summer compared to the winter, with some samples exceeding the soil pollution risk screening value. Different seasons also affected the PAHs content in plants, with tall arbors having higher PAHs content in the winter and short herbs in the summer. The source of PAHs in plants was more complex during winter. Some parks had higher levels of contamination, and the average lifetime carcinogenic risk for both adults and children reached a low-risk level in the summer, with children having a higher risk than adults.

Summary: This study investigated the seasonal variations in microplastic distribution in marine sediments in multiple-used zones of Eastern Guangdong in the South China Sea. It was found that microplastic abundance was lowest in summer, significantly lower than other seasons. The most abundant microplastic size range was 50-200 μm, and transparent and fragmented microplastics were the most frequently observed composition. Microplastic abundance was negatively correlated with distance to the coast. Seaweed ecosystems impacted microplastic abundance by changing the microenvironment and/or direct contact and entrapment. The study also identified the most frequently detected compositions and recommended appropriate management of plastic waste to reduce microplastic pollution in the marine environment.

Summary: In this study, PFAS and fatty acids were tested in squids from the southeast coastal regions of China. Higher concentrations of PFAS were found in squids from the subtropical zone compared to the temperate zone. Cooking methods were effective in reducing PFAS in squids, but caution should be taken to minimize PFAS exposure through juice and oil. Squids can be considered a healthy food due to the health benefits associated with fatty acids.
