<#LINE#>Electrochemical study of Aspilia africana leaf extract for combating corrosion of mild steel corrosion in acid solutions<#LINE#>Maduagwu @E.C.,Ahanotu @C.C.,Madu @K.C.,Chikwe @I.S.,Ikemezie @M.N. <#LINE#>1-7<#LINE#>1.ISCA-IRJEvS-2021-024.pdf<#LINE#>Department of Science Laboratory Technology, Imo State Polytechnic, Umuagwo, Owerri, Nigeria@Department of Science Laboratory Technology, Imo State Polytechnic, Umuagwo, Owerri, Nigeria@Department of Science Laboratory Technology, Imo State Polytechnic, Umuagwo, Owerri, Nigeria@Department of Science Laboratory Technology, Imo State Polytechnic, Umuagwo, Owerri, Nigeria@Department of Science Laboratory Technology, Imo State Polytechnic, Umuagwo, Owerri, Nigeria<#LINE#>14/9/2021<#LINE#>3/11/2022<#LINE#>The work studied the performance of Aspilia africana leaf (AAL) extract in retarding the corrosion of mild steel substrates in 0.5 MH2SO4 and 1.0 M HCl acid solutions. The inhibition performance and efficiency of the extract was studied using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) measurements. The results of the study indicated that AAL extract effectively inhibited the dissolution of mild steel in the said acid solutions. The inhibition efficiencies of the plant extract increased as the concentration of the leaf extract increased. The leaf extract exhibited the maximum inhibition efficiency η(%) of 98.30% and 60.82% at 700mg/L in 0.5 M H2SO4 and 1.0 M HCl respectively using electrochemical impedance spectroscopy, while potentiodynamic polarization measurements reveal maximum inhibition efficiency η(%) of 81.25% and 54.55% at 700 mg/L in 0.5 M H2SO4 and 1.0 M HCl acid media respectively. The Tafel plots of the PDP showed that the inhibitor functioned as a mix-type inhibitor in which a decreased corrosion current density resulted as extract concentration was increased, suggesting an inhibiting effect. The AAL extract was found to retard corrosion via adsorption of the extract organic molecules on the mild steel and the blocking of the active sites by hindering dissolution of metal at the anode and evolution of hydrogen at the cathode.<#LINE#>Lgaz, H., Chung, I., Albayati, M.R., Chaouiki, A., Salghi, R., & Mohamed, S.K.

The objective of the work is to seek a solution to this environmental problem. The work consists in studying the performance of concrete with aggregates from recycling. The experimental analyses involved two types of concrete: a concrete with ordinary gravels (BGO) and a concrete with 100% of recycled gravels (BGR) then the results are compared. The results of the particle size analysis show that the recycled gravels contain on the one hand a lot of elements lower than 5 mm (10.84%) which is the sandy part whereas the ordinary gravels contain less (1.32%). On the other hand, the recycled gravels contain a lot of coarse elements, compromising in the concrete the inter-granular compactness. The real densities are 2.39 g/cm3 and 2.53 g/cm3 respectively for Recycled Gravel (GR) and Ordinary Gravel (GO). The porosity of recycled gravel is higher than that of ordinary gravel. The density of recycled gravel concrete is lower than that of ordinary gravel concrete. The value of 40 of the Los-Angeles coefficient characterizes a poor aggregate in terms of impact resistance. As for the mechanical parameters, the compressive strength is 19 Mpa against 22 Mpa of ordinary gravel concrete. To have a better compactness of the granular mixture, the reconciliation of the biggest elements is necessary. This has been observed on the compressive strength which is 20 Mpa.<#LINE#>Debieb Farid (2007).@Performance and durability of concrete based on recycled aggregates contaminated by chlorides and sulfates.@University of Science and Technology Houari Boumediene, Faculty of Civil Engineering, specialty Materials, pp 41- 51.@No$Guerzou Tourkia (2019).@Influence of the pre-saturation of recycled aggregates on the behavior of ordinary concrete, Abdelhamid Ibn Badis University of Mostaganem.@Faculty of Science and Technology, Department of Civil Engineering, option Geo-materials and Environment, pp10-19.@No$Serifou Mamery (2013).@Concrete based on recycled material: influence of the type of recycled material and role of the formulation.@University Bordeaux 1, Specialty: Civil Engineering, option geo-material, pp 113-122.@Yes$Test (1998).@Apparent density@.

Apart from industrial effluent discharge, Churni and Jalangi rivers receive domestic sewage on a regular basis through drainage systems from Ranaghat and Krishnanagar municipalities respectively. Industrial effluent as well as domestic and urban sewage enter Churni and Jalangi rivers from industrial, domestic, and municipal sources. The wastewater effluent and domestic sewage affect the aquatic environment resulting in drastic changes in the river water quality of Churni and Jalangi rivers which are deleterious to both aquatic flora and fauna. This is how most of the river stretches of Churni and Jalangi are almost polluted. For the determination of the magnitude of pollution, the water quality index of river water is computed. The obtained result reveals that the present condition of surface water of Churni is in worse condition wherethe situation of Jalangi River at its downstream is comparatively better.<#LINE#>Anonymous (1996).@Standards for liquid effluents, gaseous emissions, automobile exhaust, noise and ambient air quality.@Central Pollution Control Board (CPCB), Ministry of Environment and Forests, Government of India, Pollution Control Law Series, PCL/4/1995-96.@No$Anonymous.

During the year 2018, sixteen ground water samples were taken at different locations in the study area, as well as ten parameters such as pH, electrical conductivity (EC), total hardness (TH), calcium (CA), magnesium (MG), sodium (NA), potassium (K), bicarbonate, chloride and fluoride. The very strong positive correlation are reflected in between total hardness and magnesium (0.852), electrical conductivity and sodium (0.821), sodium and fluoride (0.892) and bicarbonate and fluoride (0.715) whereas, the strong negative correlation are observed in between pH and calcium (CA) and potassium and fluoride. The rate of groundwater quality index (WQI) is from 14.59 to 413.01. The higher value of WQI is observed at Arla (S3) block due to higher value of pH, electrical conductivity (EC), fluoride, chloride & sodium.<#LINE#>Back, W.

As a result, trees store a considerable amount of carbon in their structures, and annual growth increases the carbon stored in the structure. This study investigates the diversity and carbon sequestration in tree that are grown in different landscapes of cities such as  residential areas, avenue trees, parks, industrial areas and around the lake in one of the wards of Bengaluru city. In the present study, 44 tree species belonging to 23 families were found. The total carbon content accumulated by the trees in the study area is 505 tons and total CO2 sequestered is 1852 tons which is equal to removal of CO2 emission from 5,60,000 bikes on average runs per day. Out of the six species studied, the highest carbon sequestration was found in Peltophorum pterocarpum and the lowest was found in Michelia champaca. This study also analysed the variation in pattern of dust accumulation and wax content on leaves of different tree species in different seasons. Dust is an air contaminant in urban areas that often exceeds limit values, creating serious problems due to its harmful effects on health. Planting trees and shrubs as air filters is one way to enhance air quality in these regions. Among plant species, the highest dust accumulation, irrespective of seasons was noticed in Tabebuia rosea and the highest wax content was seen in Peltophorum pterocarpum. Thus, maintaining trees in urban areas help in conserving biodiversity and ameliorating climate.<#LINE#>Prentice, I. C., Farquhar G, D., Fasham M. J. R., Goulden, M. L., Heimann, M., Jaramillo, V.
