The decomposition of algae has a greater impact on heavy metal transformation in freshwater lake sediments than that of macrophytes.

Heavy metal (HM) pollution is a major concern in freshwater ecosystem management. The different types of endogenous organic matter and the way their decomposition affects HM transformation in freshwater lakes is not well understood. An ex situ mesocosm study was conducted to compare HM transformation in sediments during anaerobic decomposition of cyanobacterial bloom biomass (CBB) and submerged cyanobacterial vegetation in Lake Taihu, known as Potamogeton malaianus (PM).

Enhanced photocatalytic degradation performance of InO/g-CN composites by coupling with HO.

Environmental pollution by organic pollutants poses a great threat to the ecosystem and human development. Solar-powered catalytic oxidation technology can solve the existing energy and pollution crisis. Hence, in this work, cubic nano-InO modified g-CN composite was synthesized by in situ calcination, then it was coupled with hydrogen peroxide for the degradation of antibiotic under visible light.

The clinical effect of WeChat-based MUST education model on patients with chronic heart failure.

Objective: To explore the effect of WeChat-based MUST nursing intervention on self-care ability and quality of life in patients with chronic heart failure.

Method: Convenient sampling was used to select CHF patients who received treatment in XX Hospital from January 1, 2020, to December 30, 2020, as the study subjects and was divided into the experimental group (n = 60) and the control group (n = 60) according to the random number table. The experimental group used the WeChat-based MUST nursing intervention, and the control group used the routine education and follow-up model.

Effect of high ammonia on granular stability and phosphorus recovery of algal-bacterial granules in treatment of synthetic biogas slurry.

The aim of the study was to investigate the application of algal-bacterial granules in treatment of high ammonia wastewater. Two identical cylindrical reactors, i.e.

Improved performance of Zn-doped SnO modified g-CN for visible light-driven photocatalysis.

The low-cost composite of g-CN modified by Zn-doped SnO nanoparticles was prepared for the first time in this work. The characterization results of XRD and SEM demonstrated that Zn was successfully doped into SnO. The formed Sn-O-Zn bonds and interaction between the Zn-doped SnO sample and g-CN in the composite were explored by FT-IR and XPS technologies.

Gibberellic acid application on biomass, oxidative stress response, and photosynthesis in spinach (Spinacia oleracea L.) seedlings under copper stress.

The mechanism of Cu tolerance in plants and its control measures are of considerable significance for the remediation of Cu-contaminated soils. Gibberellic acid (GA) is involved in plant growth and development and in the response to heavy metal stress. In the present study, changes in the biomass, oxidative stress response responses, and photosynthesis of spinach seedlings were examined under Cu stress with exogenous GA applied at concentrations of 0, 3, 5, 10, 20, 40, 60, or 80 mg L.

Efficient photocatalytic degradation of doxycycline by coupling α-BiO/g-CN composite and HO under visible light.

Antibiotic pollutants have posed a huge threat to the ecological environment and human health. In this work, α-BiO/g-CN composite was prepared and coupled with HO for the rapid and efficient degradation of doxycycline (DOX) in water under visible light irradiation. The composite exhibited enhanced photocatalytic activity and 80.

Exogenous of Indole-3-Acetic Acid Application Alleviates Copper Toxicity in Spinach Seedlings by Enhancing Antioxidant Systems and Nitrogen Metabolism.

Indole-3-acetic acid (IAA) is a potential mediator in the protection of plants from copper (Cu) toxicity and the enhancement of Cu tolerance. In this paper, spinach ( L.) seedlings were cultivated in soil containing 700 mg kg Cu and the leaves of seedlings were sprayed with different concentrations of IAA.

Effects of copper treatment on mineral nutrient absorption and cell ultrastructure of spinach seedlings.

The accumulation of heavy metals in soil has serious influence on plant growth and ecosystem balance. It is of great importance to explore the mechanism of plant tolerance to heavy me-tals. Although spinach is supposed to have strong Cu tolerance, the effects of Cu on mineral element absorption and cell ultrastructure are still unclear.

Effects of copper on the growth, antioxidant enzymes and photosynthesis of spinach seedlings.

Examination of plants with strong Cu tolerance and an understanding of their Cu-tolerance mechanisms are of considerable significance for the remediation of Cu-contaminated soil. Although spinach may be a plant with strong Cu tolerance, the threshold of Cu tolerance in this plant and its physiological response mechanisms to Cu are still unclear. In this study, we examined that the effects of different Cu concentrations on the growth parameters, antioxidant enzyme activities, and photosynthesis of spinach seedlings.

Studies on the Ecological Adaptability of Growing Rice with Floating Bed on the Dilute Biogas Slurry.

This study aimed to explore the ecological adaptability and the possibility of growing rice with floating bed on the dilute biogas slurry. The results of the experiments show that the growth stage, rice plant height, and rice yield and quality were significantly affected by multiple dilutions; rice plants cultivated with 45 multiple dilutions had better ecological adaptability than others. In the 45 multiple dilutions' group, the yield of rice was 13.
