Protecting local marine protected areas (MPAs) will improve the economic benefits of the ocean and the marine economy. The policy suggests that there should be a law ensuring that marine tourism is of high quality and environment friendly. This paper provides a guideline for further research with a strong emphasis on ocean- and marine-related economic development and tourism.We studied the electrochemical reduction based on gold electrode of a diazonium salt prepared from ethylenediamine. This is the first time where the covalent functionalization on the gold electrode of an alkyldiazonium salt, 2-aminoethane-1-diazonium chloride, is demonstrated. Torin 1 ic50 This step requires the preparation beforehand by diazotization of one amine group from ethylenediamine. The resulting electrodeposited ethylamine film was confirmed by spectroscopic characterizations from gold surface modification monitored by electrochemical quartz crystal microbalance (EQCM) coupled to cyclic voltammetry (CV). The development of chemosensors based on such a covalent functionalization of a metal can reduce the chemical threats to human health along with drastically removing contaminants according to the green chemistry principles.The production of cement releases an enormous amount of CO2 into the environment. link2 Besides, industrial wastes like silica fume and fly ash need effective utilization to reduce their impacts on the environment. This research aims to explore the influence of silica fume (SF) and fly ash (FA) individually and combine them as binary cementitious material (BCM) on the hardened properties and embodied carbon of roller compacted concrete (RCC). A total of ten mixes were prepared with 124 mix ratio at the different water-cement ratios to keep the zero slump of roller compacted concrete. However, the replacement proportions for SF were 5%-15%, and FA were 5%-15% by the weight of cement individually and combine in roller compacted concrete for determining the hardened properties and embodied carbon. In this regard, several numbers of concrete specimens (cubes and cylinders) were cast and cured for 7 and 28 days correspondingly. It was observed that the compressive strength of RCC is boosted by 33.6 MPa and 30.6 MPa while using 10% of cement replaced with SF and FA individually at 28 days, respectively. Similarly, the splitting tensile strength of RCC is enhanced by 3.5 MPa at 10% cement replaced with SF and FA on 28 days, respectively. The compressive and splitting tensile strength of RCC is increased by 34.2 MPa and 3.8 MPa at SF7.5FA7.5 as BCM after 28 days consistently. In addition, the water absorption of RCC decreased while using SF and FA as cementitious material individually and together at 28 days. Besides, the embodied carbon of RCC decreased with increasing the replacement level of SF and FA by the mass of cement individually and combined.This paper investigates the characteristics of selective catalytic reduction (SCR) with a V2O5-WO3/TiO2 catalyst by studying the key parameters and determining a method for controlling ammonia injection with a sample test bench. Four parameters are defined and adopted to represent the characteristics of nitrogen oxides (NOx) and the ammonia reaction. The effects of NH3/NOx ratio (NSR), catalyst temperature, and ammonia injection period on NOx conversion efficiency and ammonia slip are investigated. The correlation between ammonia slip and ammonia saturation storage level is studied. The experimental results show that the ammonia saturation storage level has a great impact on NOx reduction and ammonia slip. The NOx conversion efficiency and ammonia slip strongly depend on the ammonia saturation storage level. Under such conditions, the NOx conversion efficiency is best when the ammonia saturation storage level is 68.2~73%, and the value reaches 75% before ammonia slip. Pulse injection improves the NOx conversion efficiency and limits ammonia slip. Comprehensive comparison shows that the injected ratio of NH3/NOx is first larger and then smaller than is beneficial for the rapid improvement of NOx conversion efficiency; the appropriate NH3/NOx ratio and continuous injection time must be controlled, or it is easy to cause ammonia slip. Therefore, a control algorithm based on ammonia storage saturation level has been proposed. According to the difference between the actual value of ammonia storage saturation and the target value, the controller corrects the injection of urea to achieve control of ammonia storage saturation level. The period of pulse injection has little influence on the mean value of NOx at the outlet; however, it affects the peak level of NOx and ammonia slip. Using varied period pulse injection further improves the NOx conversion efficiency and restrains ammonia slip. The outlet level of NOx can be reduced by adopting a suitable ammonia pulse injection interval.The industrial revolution has marked a strong impact on financial upgradation of several countries, and increase in the industrial establishment globally has direct impact on environment because of the release of unwanted product in air and inside the water bodies. The use of dyes has increased tremendously in various industries ranging from food, leather, textile, paper, cosmetic, pharmaceuticals, etc. The problem has emerged due to disposing of the dyes in the open environment, and mostly it is disposed along with the industrial wastes into the water bodies, which becomes harmful for animals, aquatic life and human health. This review highlights the role of the nanoparticles particularly biosynthesized nanoparticles for eliminating the dyes from the industrial wastewater. There are several methods for the synthesis of nanoparticle including physical, chemical and green synthesis of nanoparticles commonly known as biological method. Among all, the biological method is considered as the rapid, easy, eco-friendly and is being performed at mild conditions. The uses of nanoparticles for removal of dyes from water minimize the hazardous impact and thus considered to be the best approach as far as water quality and safety of environment is concerned.Air pollution is a serious threat to ancient sites and cultural relicts. In this study, we collected indoor and outdoor PM2.5 samples and individual particles at the Exhibition Hall of Jinsha Site Museum in June 2020, and then the chemical components, sources, morphology, and mixing state of the fine particulate matter were analyzed. Our results show that the indoor and outdoor PM2.5 concentrations at the Exhibition Hall were 33.3±6.6 and 39.4±11.4 μg m-3, respectively. Although the indoor and outdoor concentrations of OC and EC were close, the proportion of secondary organic carbon in OC outdoor (33%) was higher than that indoor (27%). The PM2.5 was alkaline both indoors and outdoors, and the outdoor alkalinity was stronger than the indoor alkalinity. SNA (SO42-, NO3-, and NH4+) was the dominant component in the water-soluble inorganic ions; Na+, Mg2+, and Ca2+ were well correlated (R2> 0.9), and Cl- and K+ were also highly correlated (R2> 0.8). Enrichment factor analysis showed that Cu (indoor) and Cd were the main anthropogenic elements and that Cd was heavily enriched. Principal components analysis showed that the main sources of PM2.5 at Jinsha Site Museum were motor vehicles, dust, secondary sources, and combustion sources. The individual particles were classified as organic matter, S-rich, soot, mineral, and fly ash/metal particles, and most of these particles were internally mixed with each other. At last, we proposed pollution control measures to improve the air quality of museums and the preservation of cultural relicts.Green growth is emerging as a dominant policy response to climate change, resource scarcity, and environmental damages. It would be crucial for all the developing countries to pursue green growth so that poverty reduction and economic growth in harmony with resource efficiency and ecological protection can be achieved. Morocco has prioritized green growth and sustainable energy practices in order to achieve a harmonic synergy between economic development and environmental protection. In this study, we developed one TOPSIS model based on the input-output framework in order to conduct a comprehensive efficiency evaluation of the national system of Morocco. Data envelopment analysis (DEA) is applied to measure green growth efficiency for the period of 2000-2018. The comprehensive evaluation index of green growth in Morocco experienced an overall increasing trend, with a green growth score of 0.26 in 2000, achieving 0.60 in 2016. The growing resource investment index (16.30 in 2000, 29.01 in 2018) and economic benefit index (10.31 in 2000, 31.28 in 2018) are accompanied by increasing environmental impacts. CO2 emission intensity reached 29.55 CO2/t in 2000 and jumped to 58.89 CO2/t in 2018, driven by the increasing electricity demand and transportation sector. Overall, Morocco experienced a steady socio-economic growth, reflecting a strong commitment of the national government in promoting green growth. However, the dependency on fossil fuels for energy demand resulted in increasing environmental costs. Such results indicate that it is urgent to make more efforts to change the current development pathway so that the whole country can move toward green growth.Plants used for phytoextraction of metals need to tolerate toxicity conditions. Potassium (K) participates in physiological and biochemical processes that can alleviate toxicity by heavy metals, including cadmium (Cd). This study aimed to evaluate the effect of K on photosynthesis and on the changes in the antioxidant system of tanzania guinea grass [Panicum maximum Jacq. cv. Tanzania (syn. Megathyrsus maximus (Jacq,) B.K. Simon & S.W.L. Jacobs)] under Cd toxicity. Plants were grown in a greenhouse, in nutrient solution, in a randomized complete block design, arranged in a 3 × 4 factorial, with three replications. Plants were supplied with three K levels (0.4 [K deficiency], 6.0, and 11.6 mmol L-1) and exposed to four Cd levels (0.0, 0.5, 1.0, and 1.5 mmol L-1). Two plant growth periods were evaluated. High Cd level (1.5 mmol L-1) led to a reduction in net photosynthesis (76%) by causing low stomatal conductance and losses in quantum efficiency of photosystem II. link3 However, high K supply (11.6 mmol L-1) increased the net photosynthesis by 15% in plants exposed to 1.0 mmol L-1 Cd, due to upregulation of proline synthesis. Cd toxicity resulted in increases in lipid peroxidation and hydrogen peroxide concentration (35 and 50%; 25 and 30%, at first and second harvest, respectively) and reduction by 80-100% in activity of the antioxidant enzymes superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxidase, and glutathione reductase in the shoots of the grass. However, the high K supply (11.6 mmol L-1) increased the activity of these enzymes (about 50-75%) and reduced lipid peroxidation (36%), restoring cellular homeostasis. Moreover, high K supply promoted a 25% increase in spermidine and spermine concentrations in the shoots. Therefore, K reduced the Cd-induced oxidative stress and increased the net photosynthesis in tanzania guinea grass by increasing the activity of antioxidant enzymes and proline and polyamines synthesis, which enhances the tolerance of this grass to Cd.
