A Statistical Synopsis of COVID-19 Components and Descriptive Analysis of Their Socio-Economic and Healthcare Aspects in Bangladesh Perspective.

The aim of the work is to analyze the socio-economic and healthcare aspects that arise in the contemporary COVID-19 situation from Bangladesh perspective. We elaborately discuss the successive COVID-19 occurrences in Bangladesh with consequential information. The components associated with the COVID-19 commencement and treatment policy with corresponding features and their consequences are patently delineated.

Surface and groundwater quality assessment and identification of hydrochemical characteristics of a south-western coastal area of Bangladesh.

In coastal areas of Bangladesh, the problem of getting fresh drinking water is acute since the surface and groundwater of this area are affected by both seawater intrusion and anthropogenic activities. This study aims at assessing the hydrochemistry and quality of surface and groundwater of a south-western coastal area Rupsha Upazila of Bangladesh using geographical information system (GIS) technique. The hydrochemical facies revealed that the surface waters are mainly characterized by Na-Ca-HCO-Cl and the groundwaters are characterized by Na-Cl-HCO, indicating mixing composition of the natural water, while the Gibbs diagram indicates mixing processes of both the rock-water and evaporation-crystallization interactions of the surface and groundwater.
