Mechanism of elevated radioactivity in Teesta river basin from Bangladesh: Radiochemical characterization, provenance and associated hazards

Urban river pollution in Bangladesh during last 40 years: potential public health and ecological risk, present policy, and future prospects toward smart water management

“…The water quality and sediment quality data showed that Teesta River was affected by receiving heavy load of pollutants. Some researchers found radioactive and heavy elements in Teesta River water which poses higher cancer risk in that area [ 192 ].…”

Preliminary assessment of heavy metals in surface water and sediment in Nakuvadra-Rakiraki River, Fiji using indexical and chemometric approaches

“…Rivers serve a set of human and ecological functions such as water transportation, ecotourism, aquaculture, habitat facility, and defending impacts (Zhuang et al, 2018;Khan et al, 2020Khan et al, , 2021Hasan et al, 2021). River water and sediments are the fundamental and essential constituents of fluvial environment, not only delivering nutrients for benthic life but also performing as potential sinks and resultant sources of pollutants including heavy metals (HMs) (Jiang et al, 2013;Islam et al, 2015a;Pejman et al, 2015;Ali et al, 2018).…”

Primordial radionuclides in the dust samples from the educational institutions of central Bangladesh: radiological risk assessment

“…Hence, geo-environmental ruling factors can be the sources of relatively lower mean-Th/U ratio in dusts. On contrary, non-responsive and immobile characteristics of Th towards the redox-condition in the environment ( Khan et al., 2021a , 2021b ) are preventing the fractionation process of Th from the surface soil in rainy season. Moreover, insoluble precipitates (Th 4+ ) and adsorption in organics and/or clays can also be inhibited the mobility of Th ( Barnett et al., 2000 ).…”
