Distribution of Nitrogen and Phosphorus in Pore Water Profiles and Estimation of Their Diffusive Fluxes and Annual Loads in Guanting Reservoir (GTR), Northern China.

Bull Environ Contam Toxicol 2020 May 30. Epub 2020 May 30.

State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China.

Improvement of water quality has frequently been delayed due to high recycling rates of nutrients across the sediment-water interface in a reservoir. Diffusive fluxes and annual loads of ammonia nitrogen (NH-N) and phosphate (PO-P) in sediments from Guanting Reservoir (GTR) were estimated according to their vertical distribution. The average contents of NH-N and PO-P in surface pore water were higher by factors of 6. Read More

Response Patterns of Biomarkers as Tools to Identify Toxic Effects of Cadmium and Lead on Bufo gargarizans Embryo.

Bull Environ Contam Toxicol 2020 May 30. Epub 2020 May 30.

College of Life Science, Shaanxi Normal University, Xi'an, 710119, China.

Molecular biomarkers play an increasing crucial role in evaluating and predicting toxicity of metals. Expressions patterns of genes related to oxidative stress, apoptosis, immune and inflammation response in the Bufo gargarizans embryo exhibited a development dependent manner. The genes related to oxidative stress (HSP, GPx and SOD) are the first response in the development of embryo, followed by the apoptosis (Bax, BCLAF1 and TRAIL) and inflammation and immune response (SOCS3, IL-27 and IL-17D), respectively.

Effect of Graphene Oxide on Growth of Wheat Seedlings: Insights from Oxidative Stress and Physiological Flux.

Bull Environ Contam Toxicol 2020 May 26. Epub 2020 May 26.

Key Laboratory of Soil Environment and Pollution Remediation, Institute of Soil Science, Chinese Academy of Sciences, Nanjing, 210008, China.

In this study, the responses of wheat seedlings to graphene oxide (GO) were investigated at a wide concentration range of 0-1000 mg L, including oxidative stress, real-time membrane potential as well as proton and calcium ion fluxes. The results show that GO induced a hormesis effect on root growth (low concentration (100 mg L) promotion and high concentration (1000 mg L) inhibition. Oxidative stress was responsible for the growth inhibition at GO concentration of 1000 mg L, as suggested from great stimulation in the activities of antioxidant enzymes and MDA content in roots or leaves.

The Role of Phytohormones in Enhancing Metal Remediation Capacity of Algae.

Bull Environ Contam Toxicol 2020 May 20. Epub 2020 May 20.

Department of Biology, Trent University, 1600 West Bank Drive, Peterborough, ON, K9L 0G2, Canada.

Heavy metal (HM) contamination of the environment is a major issue worldwide, creating an ever-increasing demand for remediation techniques. Remediation with algae offers an ecologically safe, cost-effective, and efficient option for HM removal. Similar to plants, growth and development of algae are controlled by the hormonal system, where phytohormones are involved in HM tolerance and thus can regulate remediation ability; however, the underlying mechanisms of phytohormone function remain elusive.

The Effect of Gypsum on the Fixation of Selenium in the Iron/Calcium-Selenium Coprecipitation Process.

Bull Environ Contam Toxicol 2020 May 19. Epub 2020 May 19.

Liaoning Engineering Research Center for Treatment and Recycling of Industrially Discharged Heavy Metals, Shenyang University of Chemical Technology, Shenyang, 110142, Liaoning, People's Republic of China.

The coprecipitation of selenium (Se) with iron (Fe) is a widely practiced method for the removal of Se from mineral processing effluents, but the effect of gypsum as a major secondary mineral on the iron-selenium coprecipitation process is still of concern. In our work we first investigated the effects of pH, Fe/Se molar ratio and the neutralizing agent on the removal efficiency of Se by iron-selenium coprecipitation method. The developed two-step Fe-Se coprecipitation method (Fe/Se molar ratio of 4) was superior to the one-step Fe-Se coprecipitation method at pH 4 using CaO as base in terms of the stability of the generated Fe-Se coprecipitates.

College of Life Sciences, Henan Normal University, No. 46, Jianshe East Road, Xinxiang, 453007, China.

As the worldwide top-selling herbicide, glyphosate is ubiquitously distributed in the natural environment, and its influence on the ecological safety and human health has being increasingly concerned. In this study, mRNA expressions of GPX and three heat shock protein genes in freshwater planarian Dugesia japonica in response to glyphosate were determined, and two oxidative stress parameters were measured. The results suggested that GPX activity can be used as a more sensitive biomarker in contrast with GPX gene expression, and mRNA expressions of Hsp70, Hsp90 genes are more sensitive than Hsp40 for planarians in response to glyphosate stress.

Spectroscopy, Thermodynamics and Molecular Docking of Fraxinellone with DNA.

Bull Environ Contam Toxicol 2020 Jun 28;104(6):864-870. Epub 2020 Apr 28.

College of Chemistry and Chemical Engineering, Baoji University of Arts and Sciences, Baoji, 721013, Shaanxi, China.

Fraxinellone is an important botanical lactone compound and has been demonstrated to have insecticidal activity. To provide theoretical support to the assessment on the safety of utilizing fraxinellone as a natural insecticidal agent, the interactions between fraxinellone and armyworm DNA, salmon sperm DNA and calf thymus DNA were investigated using UV-Vis absorption spectroscopy, isothermal titration calorimetry, and molecular docking. Results showed that there were two types of combinations between fraxinellone and three kinds of DNA. Read More

Department of Fisheries, Faculty of Natural Resources and Environment, Malayer University, Malayer, Iran.

Waterbirds are considered the effective sentinels of aquatic ecosystems contamination and their feathers are widely used as non-destructive biological tools for contaminant biomonitoring. In this work, we measure and evaluate the concentrations of lead, copper and zinc in the breast feathers of three species namely Fulica atra, Anas crecca and Anas platyrhynchos in the wetland National Park Boujagh. Levels of lead (Pb), copper (Cu) and zinc (Zn) were below the threshold that causes sub-lethal and reproductive effects. Read More
