  Pages: 1 - 15
  Abstract: The assessments of the seasonal metal pollution, as well as the subsequent likely ecological and health risks, of the open waters from the lagoon area II of Ébrié system were the subject of this study. For this purpose, the seasonal mean of As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn contents of these waters determined over the period from June 2020 to May 2021 were used. The water quality guidelines SEQ-Eau (version 2) and NQE DCE-UE 2018/240 were used to assess the seasonal ecological quality of these waters. As for the seasonal biota health risks, they have been assessed with the water quality guidelines of NYSDEC, US-EPA and SAVEX. Those concerning to Human health risks, they were with WQSSW of Port Gamble S'Klallam tribe. The results showed an important ecological degradation of these waters in all seasons. This has been due to As, Cd, Hg, Ni, and Pb. The likely biota health risks are also significant in all seasons, due to As, Hg, Ni, and Pb. As for the likely Human health risks, they are also important in all seasons. They are due to As, Hg, and Ni over the study period.

Synthesis and Spectral Characterization of Chalcone dervived from
6-Acetyl-2H-1,4-benzoxazin-(4H)-3-one: Single-crystal XRD, Hirshfeld
Surface Analysis and DFT Calculations
- Authors: R. Rajalakshmi, S. Ramkumar, A. Sripriya
  Pages: 16 - 28
  Abstract: Compound (E)- 6-(3-(p-tolyl)acryloyl)- 2H-benzo[b][1,4]oxazin-3(4H)- one [6TABO] with molecular formula C18H15NO3 was synthesized utilizing Claisen-Schmidt condensation technique. FT-IR and 1H NMR spectra were recorded to recognize the different utilitarian gatherings present in the compound and affirm the synthetic construction. The UV-Visible range study uncovers that the visible is straightforward in the whole apparent locale and the retention is seen at 325.40 nm. Single-crystal XRD concentrates on show that the compound takes shape in the monoclinic framework with a space bunch P 1 21/c 1. The corresponding lattice parameters of the crystal are a = 13.0723 (7) Å, b = 7.1789 (4) Å, c = 16.1812 (9) Å, α=900, β = 109.148 (2)0, γ = 900.

Chromium (VI) Removal from Wastewater by Batch Adsorption Mode using Date
Nut Carbon
- Authors: S. Sophie Beulah, K. Muthukumaran
  Pages: 29 - 34
  Abstract: Water pollution has great impact on environmental degradation. Release of untreated wastewater containing toxic metal ions into natural waters is a threat to aquatic ecosystem and is attributed to affect the health of living things. Date nut carbon was analysed as an adsorbent for extracting Cr(VI) ions from wastewater using batch method. Investigations were done by varying the pH from 1 to 6, carbon dose from 0.1 g to 0.5 g and equilibration time from 1 to 24 hours. Cr(VI) removal of 93% occurred at an optimal pH of 2, carbon dose of 0.3 g/100mL, and equilibration time of 3 hours. The adsorption of Cr(VI) on Date nut carbon followed first order kinetics. The kinetic process of Cr(VI) adsorption onto Date nut carbon was tested by applying first order kinetics.
