The textile industry in Bangladesh has been a great engine for boosting economic growth in the country. However, with great success came environmental deterioration. Untreated effluents containing heavy metals are being released into rivers from nearby factories, affecting the health of people who live along the polluted rivers. The existing law in Bangladesh, requiring such factories to install an effluent treatment plant (ETP), has not been effective in reducing environmental noncompliance. This paper aims to investigate the reality of the situation that the textile industry faces regarding environmental compliance. It is based on primary data collected from textile factories in Dhaka through a questionnaire survey with complementary interviews. This study especially highlights the barriers and difficulties faced by factories in the installation and operation of ETPs. The results confirm previous findings: Low willingness of companies to meet environmental compliance requirements and inadequate monitoring and enforcement by government authorities. In addition, we reveal that the dominant barriers to ETP installation are at the purchase stage, rather than the construction stage: ETPs are unavailable in local markets and the import tax is high. Institutional arrangements are required to improve this situation; this could include establishing a subsidy scheme that would encourage voluntary construction of central ETPs. We suggest that external pressure is essential for Bangladesh to change and the external bodies exerting such pressure should have objective measures by which to judge compliance; the quality of river water might be the only reliable measure of environmental compliance in this situation.

Bangladesh is one of the high-risk countries of the COVID-19 pandemic and its consequent losses due to social and economic conditions. There is a significant possibility that economic stagnation would push a large population back into poverty. In the present study, we have reviewed the chronology and epidemiology of COVID-19 in Bangladesh and investigated the country’s vulnerabilities concerning COVID-19 impacts. We focused primarily on four areas of vulnerabilities in Bangladesh: The garment industry, urban slums, social exclusion, and pre-existing health conditions. The result implicated that the country would take time to recover its economy due to the vulnerabilities mentioned above, and many people in Bangladesh would not be able to tolerate the current situation because they do not have enough reserves to do so. We concluded that if at least some Sustainable Development Goals (SDGs) had been at least partly attained, the situation would not be as dire as it is now. Based on this conclusion, we suggested a tolerance capacity to indicate how long people can survive without outside support. It is a holistic assessment rather than the indicators presently defined in each SDG, but it should be attained through a harmonized approach to SDGs.

In recent times Gallbladder cancer (GBC) incidences increased many folds in India and are being reported from arsenic hotspots identified in Bihar. The study aims to establish association between arsenic exposure and gallbladder carcinogenesis. In the present study, n = 200 were control volunteers and n = 152 confirmed gallbladder cancer cases. The studied GBC patient’s biological samples-gallbladder tissue, gallbladder stone, bile, blood and hair samples were collected for arsenic estimation. Moreover, n = 512 gallbladder cancer patients blood samples were also evaluated for the presence of arsenic to understand exposure level in the population. A significantly high arsenic concentration (p < 0.05) was detected in the blood samples with maximum concentration 389 µg/L in GBC cases in comparison to control. Similarly, in the gallbladder cancer patients, there was significantly high arsenic concentration observed in gallbladder tissue with highest concentration of 2166 µg/kg, in gallbladder stones 635 µg/kg, in bile samples 483 µg/L and in hair samples 6980 µg/kg respectively. Moreover, the n = 512 gallbladder cancer patient’s blood samples study revealed very significant arsenic concentration in the population of Bihar with maximum arsenic concentration as 746 µg/L. The raised arsenic concentration in the gallbladder cancer patients’ biological samples—gallbladder tissue, gallbladder stone, bile, blood, and hair samples was significantly very high in the arsenic exposed area. The study denotes that the gallbladder disease burden is very high in the arsenic exposed area of Bihar. The findings do provide a strong link between arsenic contamination and increased gallbladder carcinogenesis.
