TL;DR: The evidence is provided that effluents discharged from the tannery and auxiliary industries and urban sewage system are the main sources of heavy metal pollution in the lagoon and canal water systems in the Hazaribagh area of southwestern Dhaka.

TL;DR: The muscle and carapace/exoskeleton of shrimp, lobster and crabs were analysed and contained various concentrations of Pb, Hg, As, Cr, Cd, Fe, Cu, Zn and Mn; crabs showed higher mean heavy metal concentrations than shrimp and lobster.

TL;DR: In this paper, the authors used atomic absorption spectrometry (AAS) to evaluate the potential human health risks from the consumption of fish, and the estimated daily intake (EDI) of all the studied heavy metals calculated on the basis of mean fish consumption of 49.5 kg person−1 d−1 by Bangladeshi households indicated that no risk to people's health with respect to the EDI of investigated heavy metals through consumption of the fish samples.

TL;DR: Trace element contamination assessment, using different environmental contamination indices, reveals that As, Sb, Th and U are low to moderately contaminated while Cd is moderately to severely contaminated in the sediments of this area.

TL;DR: In this article, the suitability of groundwater use in Dhaka City dwellers, factors affecting groundwater quality, and human health risk to initiate the control measures were investigated, which revealed that, groundwater is slightly acidic to alkaline and in some samples Fe and Mn concentrations exceed the standard permissible limits.
