Langmuir monolayer adsorption quantity was found to be, 50.0 mg g-1 and 62.5 mg g-1 for Gold HE-R and Green HE-4BD, respectively.  Pseudo-first-order, pseudo-second-order, intra particle diffusion and Tempkin kinetic models were used to fit the experimental data, it was well fitted into pseudo second order kinetics. Thermodynamic parameters such ∆Ho, ∆So and ∆Go were calculated, which shows the adsorption process was exothermic, decreasing randomness of solute and negative free energy reveals the feasibility of the reaction.  Energy of activation also predicted using Arrhenius equation, which was -16.569 and -20.710 kJ mol-1 for GHER and GHE4BD, respectively.  FT-IR and SEM analysis were also indicates the adsorption pattern effectively.

In this study, samples from food waste were taken from household of Biratnagar Metropolitan city and Kathmandu University Canteen, Dhulikhel. The samples were analyzed for physical and chemical properties and biogas production. The feed containing 6% TS were analyzed for the potential of biogas production from the canteen food waste (CFW) of Kathmandu University (KU) and household food waste (HFW) from Biratnagar in ambient and control temperature (35 ℃) in a batch reactor.  This was also conducted for food waste mixed with 30% cow manure in both the conditions. The average total solid and volatile solid for BFW were 17.7 and 93.2% of TS and CFW were 19.9 and 90.2% of TS, respectively. In every run of the experiment, the volume changes of gas were monitored. Both in the ambient and the controlled temperature, biogas production and yield were higher when 30% cow dung as inoculum was added in both samples. Moreover, the biogas production and yield of CFW was also higher than the BFW at different conditions. This shows that food wastes characteristics and biogas production potential varies depending on the source of the food waste, inoculum added and operating condition for the anaerobic digestion process.

Kinetics, mechanism and thermodynamic parameters were estimated. Adsorption capacity was rapid and time dependent as appreciable level of Pb (II) uptake was achieved at an optimum contact time of 50 minutes. Three kinetic models were used to fit the kinetic data; Pseudo- first order, Pseudo-second order and intraparticle diffusion. Adsorption of the metal ions follows the Pseudo-second order and intraparticle kinetics as these provide a better fit to the experimental data with high R2  values ranging from 0.9776 – 1. Thermodynamic parameters such as change in Gibbs free energy ( ∆Go ) change in enthalpy (∆Ho), and entropy change (∆So ) were calculated. The ∆Go   (-5.499kJmol-1), ∆Ho (60.36 kJmol-1) and ∆So (212.44 Jmol-1K-1) of the adsorption process of metal ions onto the modified adsorbent was found to be feasible, endothermic, spontaneous and physiosorption in nature. These results indicate that modified CPH is a promising sorbent for the removal of Pb (II) in industrial effluent and wastewaters containing same.

The only authorized waste disposal site at Rajbandh located at Khulna in Bangladesh. To this endeavors, total sixty soil samples were collected at a depth of 0-30 cm from the existing ground surface and the relevant metal elements of Al, As, Ba, Ca, Cd, Cr, Co, Cu, Fe, Hg, K, Mn, Na, Ni, Pb, Sb, Sc, Sr, Ti, V and Zn were measured through standard methods in laboratory. Desired results for normality test obtained from normal QQ plot using XLSTAT. Almost all the metal elements were normally distributed in both the seasons. Multivariate statistics such as Pearson’s correlation, principal component analysis (PCA) and agglomerative hierarchical clustering (AHC) were performed using XLSTAT to show the correlation between metal elements and their possible generation sources. Results of multivariate statistics revealed that almost all the metal elements were strongly correlated indicating same generation sources. In addition, results of PCA and AHC depicted that almost all the metal elements in soil derived from anthropogenic/human activities; least number of metal elements from natural sources as well as from both the natural and anthropogenic sources. Proper identification and control of possible generation sources of metal elements may reduce the threat of soil contamination due to metal elements in waste disposal site.

Climate tensions such as changing precipitation patterns, fluctuations in temperature, and extreme events are already affecting water resources. For instance, precipitation pattern will be changed due to more water vapor in the atmosphere. Hence, it will not be evenly distributed. Some places will see more rain, others will get less snow. However, climate changes, such as the amount, timing, and intensity of rain events, in combination with land development, can significantly affect the amount of storm water runoff that needs to be managed. Firstly, this essay will be discussed about the prediction of climate change using a fuzzy neural network (FNN) and it shows the accuracy of this method for anticipating storm water. Secondly, based on the results of the first phase, it determines the critical area for preparing storm water systems with the application of GIS tools and technology.

Roach with an average weight of 3.3 g and lengths of 4 cm were used in this work. Acclimatized fish were fed daily with a formulated feed.Caspian Roach were exposed to a low concentration of  10% LC50 and high concentration of 50% LC50 ofzinc for a period of  control (0), 24, 48 and 96h static toxicity examination, operated within the tank of 400L. In 10% LC50 concentration zinc (96h) immune parameters neutrophil, monocyte and lymphocyte are not shown significant change toward control group (P>0.05) and in 50% LC50 concentration zinc (96h), immune factors lym showed significant decrease toward control but neu factor significantly increase toward control group (P<0.05). Eosino and mono did not showed significant correlation with zinc exposure (P> 0.05). In low and high concentrations of zinc, results showed zinc can cause changes in hematological, biochemical and immunological factors in Caspian roach; therefore, assessment of these indicators, could be useful to detect pollution of aquatic ecosystems.

Dhaka's growing population, urbanization, and modernization are causing problems with wastewater discharges and water pollution in the river's water body. These rivers receive wastewater from numerous sources, which are discharged as industrial effluents, municipal sewage, household wastes, clinical wastes, and oils. The water of these rivers is being polluted to an increasing degree. This study investigated how the surface water in Dhaka's rivers varies throughout the year. The results of various water quality indices, such as DO, BOD, COD, pH, TDS, EC, SS, Turbidity, and alkalinity, were compared with the guidelines set by Bangladesh's Department of Environment (DoE) and the World Health Organization (WHO). Sample collection was done in two seasons in a year, dry season and wet season. In this study, researchers also aim to determine the effect of this wastewater on the river water and thus provide a report on the state of a numerical rating for determining the rivers' water quality.
