Sewage sludge (SS), a byproduct of treated wastewater by sewage treatment plants (STPs) are rich in organic C, and other macro -micro nutrients, which if properly managed can be used to improve organic fertility in intensively cropped degraded soil. A field experiment was conducted to examine the role of sewage sludge from different sewage treatment plants with various doses of phosphorus on physicochemical and macronutrient in soil depth under (Vignaradiata L.). Sandy loam soil, during Zaid seasons of 2017at the Nursery of Forestry, Department of Environmental Sciences & NRM in SHUATS, Prayagraj.Nineteen treatments were employed using three different areas STPs sewage sludge (SS) they are Naini STPs (A 1 ), Rajapur STPs (A 2 ) and Pritamnagar STPs (A 3 ) of two different doses of SS (10 t ha -1 and 15 t ha -1 ) with two-level of phosphorus (60kg ha -1 and 30kg ha -1 ) to find the effect and accumulation of macronutrient after application of SSin soil 0-15 & 15-30 cm depths. The results showed a positive effect of sewage sludge on physical and chemical parameters on treated soil. BD (g cm-3 ) and Solid space (%) was significantly decreased and highest data was recorded in particle density(g cm-3 ), pore space %, EC, OC% in both soil 0-15 & 15-30 cm depth in treatment T 3 (Naini 15 t ha -1 ) after application of sewage sludge as compared to control T 1 .pH was a basic parameter of soil it showed slightly acidic at higher concentration of SS in Treatment T 3 as compare to T 9 (Rajapur 15 tha -1 ) and T 15 (Pritamnagar 15 t ha -1 ). The study revealed that quality of Pritamnagar SS showed positive results compare to other SS of different STP because it had low pH with higher amount of NPK which enhance the soil health and the latest technology was used for treatment process of waste. Lower concentration of SS application was beneficial for soil productivity and agriculture for a short period of time.
At present, the precious water resource is of concern due to its depletion by toxic elements and organic pollutants that result in environmental hazards. The present work comprises various sponge adsorbents with unique adsorption performance in environmental remediation. Researchers explored novel chitosan and cellulose-based sponge adsorbents as green materials in the adsorption of toxins. Chitosan sponge adsorbent (MIL-101(Fe)@CS Sponge) with adsorption capacity 4518 mg/g and polyurethane sponge-based adsorbent (RCS) with adsorption capacity 1263.5 mg/g were identified as superior sponge adsorbents in dye removal.The dye adsorption on sponge adsorbents occurred predominantly through the chemical adsorption mechanism with electrostatic interaction. The adsorption capacity of sponge adsorbents in environmental remediation is in the following order (Chitosan sponge>polyurethane sponge>Cellulose sponge> Graphene sponge>luffa sponge). The current interest among researchers in using bio-materials will provide a worthy challenge and the future possibility of designing novel sponge adsorbents with unique surface properties for various applications.
Microcube structure materials (MSM) have currently gained attention due to its high surface area, high porosity and other unique surface properties that are certain requirements for materials used in energy storage devices and sensor technology. The hydrothermal/solvothermal approach proved to be effective to synthesize microcube structure materials (MSM) with good surface properties. This review discusses the various preparation methods of microcube structure materials (MSM) and its applications in energy storage devices and sensor applications.
Urban Green Spaces store higher above ground biomass (AGB) and AGB carbon (AGBC). In the present study the tree composition, diversity, dominance and carbon stocks in the AGB U.G.C. of viz., the Company Garden (C.G.), Minto Park (M.P.), Khusro Bagh (K.B.), PD Tandon Park and the Hathi Park (H.P.) of Prayagraj, India were assessed. A total of 27, 24,21,18 and 14 different tree species belong to 15,14,11,12 and 9 families were found in the C.G, M.P., K.B.,PD and H.P., respectively. In the C.G, M.P., K.B., PD and H.P the Shannon diversity index (1.22) (2.35) (2.91) (2.79) (2.50) and the Simpson index (0.050) (0.046) (0.062) (0.066) (0.094) were significant. The AGB, BGB, TGB and carbon in C.G. were (49.14) (13.27) (62.41) (31.21) respectively. However, compared to other site a higher carbon stock was found in C.G.
The rapid increase in population needs a vast amount of food and energy to survive. This review paper reveals the potential of aromatic grasses to remove nitrate loads from different sources of contaminated water. A sustainable development approach for growing food needed pure water for irrigation and drinking purposes. These days, farmers are using chemical fertilisers to increase the quantity of food energy without knowing its harmful effect: our challenge is to be aware of them with green technology and teach them how to use it sustainably. Currently, many countries are experimenting with the green approach with the help of plants; they are trying to eliminate harmful elements from contaminated water. This method of removing pollutants by plants use is known as phytoremediation. So, many countries are using it to accumulate and extract toxic substances like heavy metals and higher nutrients load from water with the help of this approach. These aromatic grasses have been identified most photo-stabiliser, hyper-accumulator, and hyper-extractor of the toxic substance and nutrient loads at contaminated sites without harming or negatively impacting these toxics to other parts of the plant. Aromatic grasses cost-effectively have higher economic value. Many studies observe that toxicity enhances the essential oil quality of these grasses and increases the value and quantity of oil. Thus, grasses are very suitable for removing nitrate from different contaminated water sites and may be they are option for ideal sustainable development approaches.
