However, there remains a significant gap about its effect on fish with different species, especially in highly-sediment-laden rivers. Here, through a large-scale investigation of microplastics in the Yellow River, our research highlighted effects of heavily sediments on MPs contamination in fish gut. MPs were 100 % tested in water, sediment and fish gut samples, with MPs in the lower reach 2∼3 times larger than that of the upper reach. Most of the microplastics were small (&lt;1 mm), fibrous and blue fragments, composed of polyethylene, polypropylene, and polyethylene terephthalate. Feeding habitat and environment significantly controlled MPs ingestion by fish (<em>p</em> &lt; 0.05), of which filter feeders and species with broader dietary preferences exhibited higher ingestion abundance, omnivorous fish abundance up to 24.9 items/individual. Heavily sediment load accelerated the fragmentation and deposition of MPs (<em>p</em> &lt; 0.05), leading to the generation of more and smaller MPs particles, increasing ecological risks to aquatic organisms. Downstream, smaller sediment size and higher organic matter content also facilitated microplastic accumulation. The prevalence of highly toxic polyvinyl chloride polymers was emerged as the major contributor to environmental risks. Our results suggested that the contribution and ecological risks of small microplastics are worth attention in the mid and lower reaches of the Yellow River.</div></div>","PeriodicalId":443,"journal":{"name":"Water Research","volume":"278 ","pages":"Article 123306"},"PeriodicalIF":11.4,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these ecosystems, coastal lagoons are particularly sensitive to anthropogenic disturbances. The Mar Menor is an example of such an ecosystem, with an extremely degraded status with high levels of anthropogenic eutrophication. As a consequence, reduced dissolved oxygen levels have been observed in this lagoon following episodic wind events that induce mixing and resuspension of bottom sediments, leading to catastrophic consequences for fish populations. Therefore, understanding the processes that control the oxygen depletion in lagoon waters is thus essential to appropriately manage the ecosystem. This study analyses oxygen consumption in the water column associated with sediment resuspension events induced by wind. The study was carried out in a laboratory, where mixing was induced using an oscillating grid device. The range of mixing intensities were selected to be close to the turbulence encountered in the lagoon's field conditions. The resuspended sediment used for the experiments had been taken from the bed of the Mar Menor at three sampling sites. The results of this study indicate that oxygen depletion in the water column during mixing increases with the amount of sediment resuspended, the mean diameter of the particles and the organic matter content in the sediment bed. Data on oxygen depletion in coastal lagoons, estuaries, seas, and reservoirs were then used to develop a predictive model for oxygen depletion, based on the concentration of resuspended sediment, its characteristic particle diameter, and the organic matter content of the sediment bed. Organic matter content was found to be the most significant factor contributing to oxygen depletion. The resulting model determines the oxygen depletion associated to sediment resuspension events with sediments affected by anthropogenic eutrophication.</div></div>","PeriodicalId":443,"journal":{"name":"Water Research","volume":"278 ","pages":"Article 123327"},"PeriodicalIF":11.4,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The historical trends of main pollutant indexes in WWTPs influent and the corresponding geographical distribution variations during 2007–2020 have been analyzed. Pollutant concentration and wastewater collection rate in northern and western regions were generally higher than southern and eastern regions of China. A wastewater collection rate of approximately 65 % by introducing actual pollutant collection amount has been proposed, demonstrating the practical conditions and problems of Chinese wastewater collection system nowadays. Correlation and redundancy analysis further pinpointed collection rate and rainfall as the paramount factors affecting influent concentrations and pollutant losses, contributing 66.9 % and 29.5 %, respectively. These results indicated that the deteriorated or damaged sewer pipelines, along with mixed or wrong connection of rainwater and wastewater, led to a large amount of extraneous clean water transported into and then treated unnecessarily by WWTPs. A significantly negative correlation between influent chemical oxygen demand (COD) concentration and electricity consumption in WWTPs was disclosed, further emphasizing the importance of increasing influent loading and rehabilitating sewer pipelines to enhance the overall efficiency of wastewater systems.

However, the lack of long-term successive monitoring data has hampered the knowledge of the current patterns of variation in the nitrogen content in QTP lakes, as well as their future trends. In this study, the variations in the nitrogen content in sediment records from Lake Hurleg and Lake Toson and collected datasets from other lakes on the QTP were analysed. In addition, the responses of the fates of nitrogen and organic carbon in lake sediments to climate change and human activities were also considered. The results revealed that the TN contents in Lake Hurleg and Lake Toson sediments have increased by 34 % and 23 %, respectively, since the 1960s compared with the pre-1960s. The nitrogen isotopic composition revealed that anthropogenic nitrogen inputs were the critical source of the increase in TN in the lake sediment and that climate change facilitated the assimilation process to alter the N level. The combined dataset with other QTP lakes revealed that TN (TOC) in QTP lake sediments increased at a rate of 0.026 %/decade (0.19 %/decade) from the 1890s to the 1990s, mainly from endogenous lake sources, and its contribution increased owing to anthropogenic nitrogen inputs. The nitrogen input increased the TOC content of the QTP lake sediments, resulting in lower TOC/TN ratios. Changes in nitrogen in QTP lake sediments were controlled mainly by climate change before the 1920s, by a combination of climate change and human activities during the 1920s–1960s, and mainly by human activities after the 1960s. These results highlight that anthropogenic nitrogen inputs are critical for increasing nitrogen levels in QTP lakes.</div></div>","PeriodicalId":443,"journal":{"name":"Water Research","volume":"277 ","pages":"Article 123330"},"PeriodicalIF":11.4,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a new cross-kingdom abundance quantification method was devised to obtain cell abundance of both prokaryotes and eukaryotes based on high-throughput sequencing, and employed to elucidate microbiomes of leachate samples collected from nationwide landfills in China. Results showed the clustering of landfills into two groups primarily based on microbial community compositions, being in line with the change in their landfill ages (i.e., Group-I, &lt;10 years; Group-II, ≧10 years), and 1320.9 and 88.0 times of abundance difference between prokaryotes and eukaryotes in the Group-I and –II communities, respectively. Reducing equivalent was determined as a primary factor governing the landfill microbial abundance, assembly and interactions. In contrast to Group-I characterized by the extensive organic matter fermentation and multi-pathway methanogenesis driven by fermenters and methanogenic archaea, aerobic heterotrophs played a primary role in element cycling and archaea-mediated methanogenic activities were diminished in Group-II communities, in which heterotrophic bacteria and fungi might synergistically degrade recalcitrant organic matter. Interestingly, protozoa and metazoa as bacteria/fungi predators decreased the stability of Group-II communities in a top-down manner. Based on these observations, a scenario was proposed for the energy-driven succession of landfill microbiomes and mediated biogeochemical processes.

Utilizing 30-meter spatial resolution Landsat-7/8 satellite data with the Finite Volume Community Ocean Model (FVCOM), this study estimated the monthly POC fluxes entering the PRE and the NSCS from 2001 to 2020. The results indicate that the annual mean POC flux entering the PRE is 0.13 Tg C/yr. Over the past 20 years, increased dam construction in the basin has resulted in a decline in the POC flux entering the PRE and a reduction in its annual variability. Additionally, the decrease in sediment concentration has increased the proportion of autochthonous POC, leading to a significant rise in POC (%TSM) in the Pearl River. Approximately 25 % of the POC from the river deposites in the PRE each year, while the remaining 0.098 Tg C of POC flows into the NSCS. Over the past 20 years, with a reduced POC flux entering the estuary, increased runoff, and a higher proportion of northerly winds, the POC deposition in the PRE has decreased by 47 %, and the POC flux entering the NSCS has increased by 8.7 %. Thus, despite the decrease in POC flux entering the estuary over the past 20 years, the increase in POC flux entering the sea influences seasonal hypoxia, carbon source-sink patterns and the nutrient structure in the PRE.
