Summary: The study found high concentrations of PFCs in the water of the Huangshui River basin, with 12 PFCs detected in crops, showing a significant positive correlation with adjacent rivers. The PFCs in the water mainly came from wastewater discharged from treatment plants and carpet factories, with resuspension in sediments also playing a significant role.

Summary: This study analyzes the temporal and spatial evolution of drought in the Haihe River Basin using the standardized precipitation evapotranspiration index and other methods. The results indicate an increasing frequency of drought in the basin, particularly a significant increase in severe and extreme drought since 1990. The barycenters of drought are mainly located in the central part of the basin, with a northeast to southwest migration trend.

Summary: This study explores the impact of natural, biogeochemical, and anthropogenic factors on vegetation greenness changes in the Haihe River Basin in China. The results indicate a significant increase in vegetation greenness in the majority of counties, with CO2 and human activities being the major contributing factors. Additionally, afforestation is a pronounced driving force for vegetation greenness changes, particularly in mountainous areas.

Summary: Through comprehensive bioinformatics analysis, the correlation between five perfluorinated compounds (PFCs) and prostate cancer was discovered, and the promotive role of perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) in the growth of prostate cancer cells was verified. This study provided novel insights into the role of PFCs in prostate cancer and raised attention to the environmental association with cancer risks and progression.

Summary: In recent decades, the river network patterns in China's Haihe River basin have undergone significant changes, becoming increasingly complex. This paper focuses on quantitatively studying the correlation between river network patterns and topography, and how the correlation has changed. The results show that topography explains 53.39% of the variance in river network patterns, and the topographic wetness stress index has a stronger explanatory power.

Summary: In this study, the molecular orientation of MA derivative monolayers at the air/water interface was investigated using HD-VSFG spectroscopy. The results showed that MA derivatives tend to adopt a standing orientation closer to perpendicular to the interface with longer R-f chain lengths and higher surface pressures.

Summary: This study assessed seven types of ET products in the Haihe River Basin in China using various validation methods. The results showed higher accuracy when the flux towers validation method was used, and some products were overestimated or underestimated when the water balance validation method was used. The uncertainty analysis indicated that GLEAM_ET had the lowest relative uncertainty.

Summary: This study examined the concentrations of 14 heavy metals in water, sediments, and fish samples from the Haihe River basin, determining the ambient water quality criteria (AWQC) values and conducting a comprehensive risk assessment. The health risks posed by certain heavy metals and ecological risks associated with others were highlighted, with sensitivity analysis identifying key contributing parameters for each metal. This research provides valuable information for water quality assessments and standards development.

Summary: Understanding public perceptions of urban public spaces through deep learning analysis of social media data provides new opportunities for improving urban vitality and spatial diversity. This study developed a VGG-16 image classification method and found that images of the Haihe River in Tianjin are dominated by skyscrapers, bridges, and promenades. The spatial distribution of Flickr images revealed three vitality areas in the river.

Summary: This study investigated the occurrence, distribution, and ecological risks of pharmaceuticals and personal care products (PPCPs) in sediments of the Haihe River in Northern China. The vertical distribution of PPCPs in core sediments was examined. The study found that the concentrations of PPCPs in the sediments were relatively low and had no severe adverse effects on aquatic organisms. However, attention should be paid to the environmental risks posed by highly loaded and mobile PPCPs.

Summary: This study explores the performance and adaptability of LSTM in water quality prediction in the Haihe River Basin. The findings indicate that LSTM presents better predicting on BOD, CODMn, CODCr, and TP, while the prediction performance is poorer for NH3-N, DO, and pH. Additionally, the performance of LSTM in predicting water quality is linearly related to the maximum value of temporal autocorrelation and cross-correlation coefficients of water quality indicators.

Summary: The environmental concentrations of seven ECs were studied in dated intertidal saltmarsh cores from two estuarine sites in the southern U.K., revealing the mobility of these contaminants in the marsh systems and their lack of clear association with input trends or sediment geochemistry changes.

Summary: Per- and polyfluoroalkyl substances (PFAS) have been extensively used as surfactants and repellents. This study reviewed the global contamination pattern of PFAS in marine biota, focusing on seabirds as biomonitoring tools. The study found that PFOS was the most studied PFAS in seabirds, with the highest levels observed in eggs of common guillemots from the Baltic Sea. The temporal pattern showed higher levels of PFOS in the late 1990s and early 2000s, coinciding with the phase-out of perfluorooctane sulfonyl fluoride-based products.

Summary: Water quality monitoring stations are essential for detecting excess pollutants in river sections, but identifying the causes of these exceedances can be challenging, especially in heavily polluted rivers with multiple contamination sources. In this study, we used the SWAT model to simulate pollution loads from different sources in the Haihe River Basin and analyzed the spatiotemporal distribution of pollutants. The results highlight the need for targeted prevention and control policies based on the primary sources of pollution loads in different regions.
