Abstract: The date stones were obtained from the market place and the feasibility of utilizing low-cost carbonized date stones for the removal of erythrosine dye from an aqueous media was carefully conducted under laboratory restricted conditions. Experimental parameters such as temperature, pH, dosage, and concentration were painstakingly maintained. Outcomes show the efficient removal of the contaminant by the substrate CDS (Carbonized date stones), Kinetics models “pseudo-first and pseudo second order was applied. Afterwards, the Langmuir and Freundlich adsorption isotherms were utilized to identify the adsorption mechanisms. The mechanism of this adsorption process displayed Langmuir adsorption isotherm which is a monolayer with R2 value of 0.9780 which is higher than that of Freundlich with R2 value of 0.8933. Also, the research work showed that the adhered and suitable kinetic model for the removal of erythrosine dye using carbonized date stones was pseudo second order due to the adsorption capacity of the dye at equilibrium qe was high at the value of 1.8900 to 8.3689 in pseudo second order compared to pseudo-first order with 7.4567.

Abstract: In M'pody village of Anyama district, an epidemic of diarrhoea was detected in January 2020. These cases of diarrhea would be linked, according to the population concerned, to the consumption of water from the improved village hydraulic system (IVH), which has not been maintained for nearly 3 years. The objective is spatio-temporal assessment of the quality of drinking water in M'pody. The methodology consisted in carrying out four campaigns to collect water samples from well, rivers and the single borehole. Classical physico-chemical parameters were determined by electrochemical and spectrophotometric methods. Microbiological analysis was carried out using membrane filtration technique. Results showed that the waters analyzed were weakly mineralized and all contained germs that were indicators of faecal pollution. The parameters implicated in the non-potability of the well, borehole and river water during the four seasons concerned turbidity, pH, nitrite, ammonium, total iron and the following germs: Escherichia coli, Enterococcus, Pseudomonas and sulphite-reducing anaerobes. Furthermore, Kohonen’s Self-Organizing Map (SOM) resulted in four classes. Class I is made up of 68.05% of samples in the database. Class II comprises 21.18%, Class III contains 2.77% and class IV represents 7.98% of the samples. To limit water pollution, the following measures should be recommended: isolate the deep aquifers from the superficial aquifers by resistant casing, protect roof from external contributions, install sanitation facilities downstream of wells and boreholes, move waste dumps and latrines away from wells and boreholes.

Abstract: Different settlers were producing diverse quantities of trashes which significantly shake the surroundings in direct and indirect way with their polluted nature over the soil property worsening. Consequently, this study was intended to investigate the public discarded materials impact on soil features in southeast Ethiopia. Prior to collecting soil samples, contact with the official and local communities as well as negotiations were done in instruction to obtain facts around the deteriorating scheme besides its influence. From a dry waste disposal site, a composite of soil sample would be taken from horizontal (0m or onsite, 20m or offsite), vertical (0-30cm, 30-60cm), and replication at a dry urban waste disposal sites. A silhouette depth was excavated on apiece sites plus tasters were composed of pits of 0-30cm as well as 30-60cm. Mechanical examination results has shown that all samples at different horizons entirely were nonsignificant in bulk density at the surface and subsurface of onsite and offsite and soil moisture at the offsite. Moreover, bulk density, cadmium and Nickel are excess in both onsite and offsite as well as at the surface and subsurface of onsite and offsite, respectively. As a summary, the analysis output indicated as urban removal takes a poisonousness outcome on the soil properties. Therefore, intensive caring for the polluted soils is necessary to regulator and inhibit the hazards from these soils. Also, the management was a requisite to destabilize the reason of leftover and handling the discarded using phytoremediation as well as bioremediation system.
