Summary: A study analyzed 100 agricultural soil samples from the Yellow River Delta in China for six priority phthalate esters (PAEs) according to the US Environmental Protection Agency. The study focused on PAEs contamination characteristics and potential health risks. The study found that PAEs were detected in all samples, with concentrations ranging from 1.087 to 14.391 mg center dot kg(-1) and the most abundant PAEs being DEHP and DnBP. Higher PAEs content was observed in the western and central parts of the delta region and around Laizhou Bay. The sources of PAEs in the soil were identified as pollutant emissions from industries, plasticizers or additives, fertilizers, and pesticides. The study also highlighted the relatively low non-carcinogenic risk from PAEs exposure in agricultural soils, but higher risk in children compared to adults.

Summary: This study investigated the concentration of PAEs in sediments of the Fengshan River system in Taiwan and assessed the potential ecological risks during the dry and wet seasons. The results showed that the concentration of PAEs was higher during the wet season in the river channel stations, but higher during the dry season in the downstream and estuary stations. The PAEs in sediments of the Fengshan River may pose low to moderate potential risks to aquatic organisms.

Summary: The study investigated the microbial community and functional potential along a natural salinity gradient in wetlands of the Yellow River Delta. Different zones showed distinct microbial compositions and abundances, reflecting the adaptability and sensitivity of microorganisms to salinity levels. Salinity was identified as a key factor shaping microbial processes, with total nitrogen and total phosphorus playing important roles at the phylum and genus levels.

Summary: This study investigated the driving factors of rural domestic waste generation and potential polluting components in water in a typical town in the Yellow River Delta. The consumption of cleaning products and household food consumption were found to have significant effects on waste generation and water pollution. Pilot projects effectively reduced potential polluting components in village waste.

Summary: This study analysed the spatiotemporal pattern of urban-rural construction land transition in the Yellow River Basin of China from 2000 to 2020 and explored its determinants using the gradient boosted decision tree (GBDT) model. The results showed an increase in both urban construction land and rural residential land, with the annual growth amount of urban construction land being three times that of rural residential land. The determinants of urban construction land, rural residential land, and the proportion of urban construction land varied, with socioeconomic factors playing a dominant role in urban construction land transition and physical geographic factors influencing rural residential land transition.

Summary: This study assessed the impacts of sewage discharge and dam interception on the inputs, variations, and sources of phthalate esters (PAEs) in the Haihe River in northern China. The results showed that the yearly inputs of PAEs from the river to the nearby Bohai Sea were considerable compared to other large rivers worldwide. The concentrations of PAEs varied seasonally and were influenced by runoff, biodegradation, urbanization, and industrialization levels. The dam intercepted a significant amount of PAEs, but also accumulated a substantial quantity behind the dam. The dominant sources of PAEs were basic residential necessities and industrial production.

Summary: The problem of imbalanced urban-rural development in China is becoming serious. Urban-rural integration is an important way to narrow the gap and promote rural development. This study evaluates the level of urban-rural integration in the Yellow River Basin (YRB) and proposes development strategies for different zones. The results show that the URIL in the YRB has been increasing, with a spatial clustering pattern and a spatial disparity between economic development and the ecological environment.

Summary: This study investigated the pollution characteristics of phthalate esters (PAEs) in sediments of the Yangtze River, and found that DEHP could potentially be used as an indicator for microplastics (MPs). DEHP, DIBP, and DBP posed high risks at the monitoring sites.

Summary: Irrigation plays a crucial role in global agriculture, contributing to 36% of food production. The quality of irrigation water is important for crop growth and food safety. This study examined agricultural water resources in the Yellow River Delta and assessed their quality using six evaluation methods. The results showed that the Yellow River water is suitable for irrigation or unconventional water utilization, but high levels of Na+ and Cl- pose a primary concern. Rainfall also supplements the water resources in this region. Therefore, implementing saline water irrigation and salt-tolerant crop cultivation can help improve coastal agriculture in the Yellow River Delta.

Summary: The study found that virtual water trade in the Yellow River Delta exacerbates water scarcity issues, with exports exceeding imports, particularly in the agricultural sector. Recommendations include implementing a virtual water trade strategy, reducing water exports, and implementing an effective virtual water compensation policy.

Summary: This study investigates the spatiotemporal distributions of six phthalic acid esters (PAEs) in the surface sediments of the Songhua River. The results show that the concentration of PAEs is higher in the spring compared to summer and autumn, and the upper reaches of the river have higher PAEs concentrations than the middle and lower reaches. Dibutyl phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP) are the most abundant PAEs. Ecological risk assessment reveals that DBP and DEHP pose moderate or high risks to aquatic organisms. Agricultural sources are identified as the primary contributor to the PAEs pollution.

Summary: Nested models were used to simulate variations in hydrological processes, soil water, and salt transport in the reconstruction area of the Yellow River Delta. The results showed that gate dams near the sea area were more effective in reducing water depth variations, and scenarios with 6 m gate valves had higher water depth changes than those with 3 m sluice valves. Rapid changes in soil water and salt content occurred during non-flooding periods, and the fluctuation of soil salt content was opposite to soil water content changes in different soil layers.
