Currently, the water pollution is an important issue in Bangladesh as well as in the world. The Sylhet city in Bangladesh is suffering from lack of structured sewerage and drainage systems with somehow improper management of solid wastes. Consequently, such wastes are discharged into the nearby Surm...

Environmental measures have drawn more attention recently as a means of identifying cost-effective, safe, and green approaches in analytical methods. As a result, white and green analytical chemistry was developed. Greenness, whiteness, and chemical risks are all measured under the general expressio...
