“…Among the studied rivers, Buriganga, a major river near Dhaka, was heavily polluted with heavy metals, followed by other urban rivers (e.g., Dhaleshwari River), while tracing elements accumulated in vegetables through irrigation with contaminated river water (Ratul et al 2018;Hasan et al 2020). Similarly, the variability of the water quality of other major rivers including transboundary streams of such as the Ganges for Indian subcontinents, and Halda for Bangladesh were also dominated by the abundance of toxic heavy metals Islam et al 2020;Haque et al 2020). However, the concentration of arsenic varied depending on the sampling site.…”

“…For this reason, it is possible to obtain positive and significant correlation results between Mn and Fe in both sampling periods (Huang et al 2009). In addition, the positive correlation between Fe and Mn indicates that they are affected by similar lithogenic sources (Islam et al 2020). While a weak correlation was observed between Cr and Fe (R=0.14, p>0.05) before the COVID-19 lockdown period, a positive correlation (R=0.47 p<0.005) was observed during the COVID-19 lockdown period.…”

The first COVID-19 case in Turkey was reported on March 10, 2020, by the Ministry of Health of the Republic of Turkey. Due to the increasing number of cases, a curfew was declared on weekends as of 11-12 April 2020. Although curfews were only implemented on public holidays and weekends, there were reductions in industrial, traffic, and human activities. The restrictions and curfews implemented to prevent the spread of the COVID-19 pandemic are a unique opportunity to understand the effects of anthropogenic sources on water quality. In this study, it was aimed to determine the temporal variations of the concentration of seven heavy metals (HMs) (Fe, Mn, Cu, Al, Cr, Ni, and Zn) in surface waters before and during the COVID-19 lockdown period, and their carcinogenic and non-carcinogenic risks that may occur through digestion and dermal absorption. Surface water samples were taken from 14 different sampling points within the borders of Bursa (Turkey). HM concentrations except Ni increased at rates ranging from 7.92% to 83.33% during the COVID-19 lockdown period compared to before the COVID-19 lockdown period. The heavy metal pollution index and heavy metal evaluation index increased during the COVID-19 lockdown period compared to before the COVID-19 lockdown period. Also, according to the results regarding the carcinogenic risk that may occur via digestion and dermal absorption, serious risks were determined for adults and children in both periods. Generally, similar correlation coefficients were obtained in both sampling periods, and it was concluded that HMs were affected by similar sources.
