Arbuscular mycorrhizal fungi (AMF) exist widely in soil polluted by heavy metals and have significant effects on plant growth cadmium (Cd) uptake. Cd contents differ among wasteland, farmland slopeland soils a lead-zinc mining area Yunnan Province, Southwest China. The of AMF maize growth, root morphology, low-molecular-weight organic acid (LMWOA) concentrations uptake were investigated via root-bag experiment. results show that increased Cd-polluted soils, resulting increases length,...

Photobiological hydrogen production is among the most promising ways toward mass of energy. The use green algal aggregates to produce photobiological has attracted much attention because it overcomes limitations sulfur deprivation and oxygen scavengers. However, current preparation that are capable time-consuming laborious, leading a difficulty in large-scale applications. Here, we demonstrated chemical flocculation algae able generate for production. We find Chlorella pyrenoidosa can...

Activated carbon is a good non-polar adsorbent. Because of its huge specific surface area and micropore, adsorption performance recycling, it can be used together with variety substances to adsorb various properties wastewater. This paper mainly introduces the structure, mechanism, modified activated carbon, microbial bound microwave future research direction carbon.

Abstract In 2016, China increased sustainability practices among companies listed on China’s stock market, making environmental regulations one of their integral policies. This states that highly polluting industries like the energy industry are required to comply with requirements set. Concerning this event, research was conducted in 2016 2017, development disclosure (ED) and impact different variables index (EDI). Focusing 150 Shanghai Shenzhen exchange, findings show if company had a...

Although the ecological risk of emerging contaminants is currently a research hotspot in China and abroad, few studies have investigated pesticide pollutants Chinese coastal sediments. In this study, nine included "List New Key Pollutants for Control (2023 Edition)" issued by government were used as objects, environmental exposure China's sediments was analyzed. The baseline sediment quality criteria deduced using balanced distribution method, multi-level assessment pesticides performed....

A pot experiment was conducted using maize (Zea mays L.) as the host plant grown in cadmium (Cd)-polluted soil and inoculated with an arbuscular mycorrhizal fungus (AMF), Funneliformis mosseae. The effects of AMF on Cd uptake by maize, water-stable aggregate proportion, concentration pore water leaching were investigated. results showed that significantly promoted biomass shoots, increased content total easily extractable glomalin-related protein 0–40 cm layers. Furthermore, proportion >0.85...

A simple but efficient fluorogenic probe is reported for accurate imaging of ulcerative colitis via hypoxia detection. The produced by can lead to the upregulation nitroreductase (NTR). NB-NO2 provides a unique response NTR, enabling Dextran sulphate sodium (DSS)-induced in vivo.

Data-driven event analysis has gradually become the backbone of modern competitive sports analysis. Increasingly, data tasks use computer vision and machine learning models for intelligent Existing visualization systems focus on player–team visualization, which is not intuitive enough team season win–loss game time–series neglects prediction all-star players. This study used an interactive system, NPIPVis designed with parallel aggregated ordered hypergraph dynamic hypergraphs, Calliope...

In all drugs contaminated with the environment, antibiotic abuse has become a global problem because of its high rate consumption in veterinary and human medicine, antibiotic-induced bacterial resistance toxicological damaged to organisms environment are increasingly being studied at home abroad. this paper, residues antibiotics soil were introduced, ecological effects reviewed, new idea was provided for future research.

Abstract Pot experiments were carried out to study the effects of intercropping by Chenopodium ambrosioides L. and maize on root exudates soluble sugar amino acids, in order understand relationship between cadmium accumulation plants. The results showed that, compared with monoculture system: (1) after maize, content C. increased 106.54%, acids 52.73%, available Cd rhizosphere soil 12.09%, 15.52%. (2) 40.41%, 70.59%, 29.35%, shoot 208.26%. (3) There significantly posotive correlations...

Conducting research on the status and response to coastal marine debris microplastic pollution is of significant scientific value importance for understanding characteristics pollution, as well addressing managing harm microplastics ecological environment. This study focused investigating at two beaches in Qingdao. explored types, sources, components, spatiotemporal distribution through field surveys, sample analysis, component identification, mathematical statistics. Based this, proposed...

In view of the colder winter conditions in north China, and taking into account high removal rate low operating cost biological wastewater treatment methods, which is leading process for organic wastewater. This paper selects technology to treat urban sewage Northeast China winter. Temperature one most important factors that affect microbial activity, therefore, application biochemical treatment, effect greatly affected by temperature. order solve problem temperature, cold-resistant bacteria...

Abstract Background Aiming at unbalanced coordination of irrigation and fertilization winter wheat in the eastern North China Plain, this study investigated effect fertigation on grain yield, quality, water use efficiency (WUE) nitrogen (NUE) seven (N) treatments. Under field conditions, traditional method (total N amount 240 kg ha −1 , application 90 sowing jointing anthesis, with topdressing 150 jointing) was used as control (CK). There were six treatments to compare CK. For treatments,...

The origin of microplastics and the effects ecotoxicological on organisms were summarized in this paper. Microplastics can directly affect environment, such as being ingested by organisms. Because are small size, they be eaten mistake, so inhibit digestive system, respiratory immune reproductive system genetic level will gradually release chemicals added production process, these have toxic effect environment. When environmental factors change, additives contained components degraded...

In the past ten years, research of Chinese scholars in process modelling activated sludge mainly focused on following aspects: Applicability diagnosis and evaluation existing models practical problems, improvement parameters models, application simulation technology modelling, development new combinatorial etc. This paper aims to grasp future trends related through a clear understanding progress.
