Summary: Identifying and quantifying the source of heavy metal pollution is crucial for soil pollution control. The APCS-MLR, UNMIX, and PMF models were used to determine the pollution sources of Cu, Zn, Pb, Cd, Cr, and Ni in farmland soil near an abandoned iron and steel plant. The models were evaluated for their sources, contribution rates, and applicability. The results showed that the APCS-MLR and UNMIX models could accurately allocate pollution sources, while the PMF model was less accurate. The combination of multiple models improved the accuracy of pollution source analysis for soil heavy metals. These findings provide a scientific basis for further remediation of heavy metal pollution in farmland soil.

Summary: The study compared three mature receptor models to investigate the mechanisms by which parameters influence the source apportionment results. Results showed that the FA-NNC and PMF models produced similar results, while the PCA-MLR model was more stable. When the sample size was reduced, similar source profiles were extracted consistent with all samples. However, the overall contribution rates were not as stable as the source profiles. FA-NNC and PMF performed better in terms of contribution rate stability and source profile stability, respectively. Improvements in goodness of fit were associated with decreased relevance among variables, indicating decreased credibility of the results. Thus, finding an appropriate sample size is more suitable for source apportionment models than involving too many samples.

Summary: The extensive economic growth has a significant negative impact on the ecology, resulting in prominent soil pollution problems. This study focuses on an industrially developed city in eastern China to understand the current situation of soil pollution, identify pollution sources, and assess future pollution risks. The application of the PMF and Unmix models reveals various pollution sources, including industrial discharge, traffic emissions, and natural sources. The study finds that pollution of heavy metals such as Hg, Ni, and Cr is primarily caused by industrial discharge, while Cd pollution is related to traffic emissions. Cu and Zn pollution are attributed to a combination of sources such as soil parent material, traffic emissions, and industrial discharge from electronic enterprises. Pb pollution is influenced by both natural sources (e.g., soil pH) and industrial sources (e.g., industrial waste discharge). Enrichment is influenced by soil parent material and agricultural inputs. The findings suggest that soil heavy metal pollution in the study region is mainly caused by human activities, supplemented by natural factors.

Summary: Polychaete worms can eliminate polycyclic aromatic hydrocarbons (PAHs) in environments by increasing their water solubility. A novel omega GST gene identified from Perinereis aibuhitensis plays an important role in the phase II detoxification of PAHs in polychaete worms. The gene expression of omega GST is positively correlated with the concentration of benzo[alpha]pyrene exposure but negatively correlated with the exposure of PAH benzene rings.

Summary: In this study, the microbial communities in two coastal areas near the estuaries of the LH River and YLJ River in the Northwestern Pacific Ocean were investigated. Geographical segregation and significant environmental heterogeneity were observed between these two areas due to the existence of the Liaodong Peninsula and different levels of urbanization. There were significantly different regional species pools and biogeographic patterns for both bacterial and protistan communities between LH and YLJ coastal areas. The dominant drivers of differences in bacterial and protistan communities between the LH and YLJ coastal areas were variation in regional species pools and species turnover. Local community assembly mechanisms, including heterogeneous selection and dispersal limitation, played important roles in shaping the bacterial and protistan communities in a single-studied area.

Summary: The marine environment is an important sink for many land-origin pollutants, and coastal and offshore areas are used to study the transfer process and exchange mechanism of organic compounds. A year-long study in a coastal area of North China found high concentrations of chlorinated paraffins (CPs) and polycyclic aromatic hydrocarbons (PAHs) in air samples. Different gas-particle partitioning models suggest that the steady-state hypothesis provides a better explanation for land-ocean exchange. The source-sink influences of CPs and PAHs are affected by atmospheric motion, alternating between gaseous diffusion and particulate sedimentation in different seasons. Source apportionment results show different transfer characteristics contribute to the source divergence of CPs and PAHs within a 12 nautical mile radius in the same area.

Summary: Legacy and emerging PFAS have been widely detected in various environmental media, with significantly higher concentrations of legacy PFAS compared to emerging PFAS indicating the continued use of legacy PFAS products in China. The decreasing trend of legacy PFAS concentrations in mollusks after 2015 suggests a gradual withdrawal of these products from the market due to China's implementation of the Stockholm Convention. Positive matrix factorization identified six primary pollution sources, with the fluoropolymer industry being the largest contributor to environmental PFAS pollution in the region, accounting for 68% of the total pollution.

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.
