The use of insensitive munitions such as 3-nitro-1,2,4-triazol-5-one (NTO) is rapidly increasing and is expected to replace conventional munitions in the near future. Various NTO treatment technologies are being developed for the treatment of wastewater from industrial munition facilities. This is the first study to explore the potential phytoremediation of industrial NTO-wastewater using vetiver grass (Chrysopogon zizanioides L.). Here, we present evidence that vetiver can effectively remove NTO from wastewater, and also translocated NTO from root to shoot. NTO was phytotoxic and resulted in a loss of plant biomass and chlorophyll. The metabolomic analysis showed significant differences between treated and control samples, with the upregulation of specific pathways such as glycerophosphate metabolism and amino acid metabolism, providing a glimpse into the stress alleviation strategy of vetiver. One of the mechanisms of NTO stress reduction was the excretion of solid crystals. Scanning electron microscopy (SEM), electrospray ionization mass spectrometry (ESI-MS), and Fourier-transform infrared spectroscopy (FTIR) analysis confirmed the presence of NTO crystals in the plant exudates. Further characterization of the exudates is in progress to ascertain the purity of these crystals, and if vetiver could be used for phytomining NTO from industrial wastewater.
Purpose: This paper aims to depict the recent initiation to evaluate the efficiency of a nation in converting wealth to well-being in terms of Sustainable Economic Development Assessment scores (SEDA) specially analyzed for the global powerhouse countries accommodating 78% of the world’ population and 87% of countries income.Design/Methodology/Approach: SEDA (Sustainable Economic Development Assessment) measures sustainable development with three broad dimensions: economic, sustainability, and environment. The analysis is carried out by plotting a four-quadrant matrix chart to compare some macro-economic fundamentals.Countries Considered: 36 Powerhouse countries of the world (78% of the world’s population and 87% of countries’ income).Variables Considered: GDP/Capita, Wealth to well-being coefficient, SEDA score, employment (Employment has unemployment and employment to population ratio 15 plus), education (school enrollment, tertiary, years of school primary to tertiary, teacher-pupil ratio primary and an average of math and science score), equality (Gini index, inequality in education and inequality in life expectancy) and finally environment (air quality, terrestrial and marine protected areas, carbon dioxide intensity and electricity production from renewable sources).Findings: The analysis depicts how good a country is in converting their wealth to well-being. The countries that have started well do not necessarily have depicted outstanding progress in Sustainable economic development assessment. Some countries are good in growth and increasing their developmental scores (keeping in mind BCG identified parameters of sustainable development). Further comparisons express a high positive correlation between GDP/Capita with education and equality. There is a very low degree of correlation between GDP/Capita and employment and a low correlation between GDP/Capita and environment. However, there is a negative correlation between Growth and development.Practical Application: Relation between GDP/Capita of countries and some important economic, investment, and sustainability dimensions to judge where a nation stands and what should be added as a prelim agenda to countries dashboard.
The world leaders now aim at establishing an overall development scenario rather than only considering the Gross Domestic Product (GDP) a true reflection of a countries well being. This paper aims to depict the recent initiation to evaluate the efficiency of a nation in converting GDP
