Microplastic (MP) pollution, an emerging global change factor, disturbs the ecosystem functioning. Inland wetlands, providing important services, might be sink for MPs. Understanding distribution, source, and fate of MPs in inland wetland ecosystems is a prerequisite developing effective management strategy. Here, different types including river wetland, constructed lake were selected to explore pollution patterns therein. Results showed that abundance soil ranges from 532 4309 items/kg. Transparent, fibers, polyethylene terephthalate most common color, shape, polymer type MPs, respectively. The this study did not significantly remove was one main sinks had accumulated large amounts In addition, MP characteristics cluster analyses aquaculture, agricultural cultivation, domestic waste sources area. occluded particulate organic carbon content related abundance. conclusion, reveals special river-constructed-lake which would help better understand distribution source wetlands have implications subsequent control ecological restoration wetlands.

Eutrophication and its resultant cyanobacterial blooms are a severe environmental issue in global water bodies, phosphate is regarded as one of the primary triggers. In this study, situ-synthesized heated kaolinite lanthanum hydroxide composite (HKL-LH) was used to treat through removal. A typical cyanobacteria species—Microcystis aeruginosa—was selected target organism. HKL-LH efficiently removed solution with inoculation M. aeruginosa over course day. good performance on control initial cell densities ranging from 104 cells mL−1 105 observed. Although genetic expression relating photosynthesis division upregulated under stress phosphorus deficiency, growth significantly inhibited, i.e., inhibition rate up 98% achieved by 0.1g L−1 HKL-LH. addition growth, photosynthetic activity viability were decreased Furthermore, production associated toxins (microcystins) algal organic matters effectively which can reduce ecological risk challenges that follow treatment. it shown has excellent application potential mitigation eutrophic water.

River ecosystem health assessment (REHA) is crucial for sustainable river management and water security. However, existing REHA methodologies still fail to consider the multiple effects of input uncertainty, environmental stochasticity, decision-maker’s bounded rationality. Moreover, studies primarily focused on plain areas, leaving Qinghai–Tibet Plateau (QTP) understudied despite its ecosystems’ heightened fragility complexity. To address these gaps, this study combined Pythagorean fuzzy sets with cloud modeling proposed (PFC) approach. Accordingly, a novel robust model (PFC-TODIM) was created by expanding conventional TODIM method PFC algorithm. We provided an indicator system tailored distinctive characteristics in QTP, leveraging multisource data. health, driving mechanisms, potential threats were investigated Lhasa (LR) using PFC-TODIM model. Results showed that effectively took uncertainties into consideration, thereby improving accuracy robustness. In LR, conditions demonstrated substantial spatial disparities. Sampling sites 28%, 48%, 24% subhealthy, healthy, excellent, respectively. Findings anthropogenic factors, such as dams, urban development, fish release adversely affect should be properly managed.
