“…Most of the physicochemical characteristics are below the DoE recommended standard for drinking and surface water quality. Due to lower concentration of DO and increasing BOD and COD value ( Table 1 ), the river water is becoming unsafe for human consumption and flora and fauna in Karnaphuli River [ 128 , 129 , 130 ]. In figure S9 and S10 , certain peak points might be due to some extreme pollution events occurred on that designated time.…”

River water is very much important for domestic, agriculture and industrial use in Bangladesh which is in critical condition from long time based on research data. During last 40 years, extreme pollution events occurred in peripheral rivers surrounding Dhaka city and Karnaphuli River in Chittagong city. Present data showed that other urban rivers are also in critical condition especially Korotoa, Teesta, Rupsha, Pashur and Padma. The pollutants flowing with water made a severe pollution in downstream areas of rivers. Metals concentrations in river water was found to be higher in dry season. Dissolve oxygen (DO) was nearly zero in Buriganga River and several points in Turag, Balu, Sitalakhya and Karnaphuli River. NO 3 - , NO 2 - and PO 4 3- pollution occurred in different rivers. Zn, Cu, Fe, Pb, Cd, Ni, Mn, As and Cr concentration was above drinking water standard in most of the river and some metals was even above irrigation standard in water from several rivers. Sediment data showed very much higher metal concentrations in most of the rivers especially peripheral rivers in Dhaka and Karnaphuli, Korotoa, Teesta, Rupsha and Meghna River. Metal concentrations in sediment was above US EPA threshold value in most of the rivers. Metal concentrations in fish and agricultural crops showed that bioaccumulations of metals had occurred. The concentration of metals showed the trend like: water

“…These sources are continuously inputting a huge quantity of pollutants into the river. Apart from these, salinity intrusion from the Bay of Bengal is also altering the physicochemical properties of the river ecosystem area and accelerating river water contamination [19].…”

“…The health risk assessment for two population groups (adults and children) were done base on their body weight and exposure time. Increasing developmental and industrial activities along the river were identified as the cause of this pollution which was making the water unsuitable for use [18][19][20][21]. To the best of our knowledge, there has been no study conducted yet to investigate the water physicochemical parameters and heavy metal pollution from upstream to downstream of the river.…”

Despite significant contributions to the national economy of Bangladesh, various urban developments, massive industrial and growing shipping activities are making the water of many urban rivers, including Karnaphuli River, extremely polluted. To find out the pollution sources and their possible health effects, 45 water samples were collected from 15 sampling stations. Investigation of six physicochemical parameters (pH, temperature, total dissolved solids, conductivity, salinity, and turbidity) through in-situ measurements and eight heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) status using atomic absorption spectrophotometer (AAS) was carried out in this research. Both the physicochemical parameters and heavy metals exceeded the World Health Organization (WHO)’s permeable threshold limit. The calculated hazard quotient (HQ) and hazard index (HI) ingestion values indicate non-carcinogenic risk both for adults and children, but dermal exposure was within the safety limit. Carcinogenic risk analysis revealed that Cd could cause a risk of cancer in those using the river water for a long period. Spatial analysis and metal pollution index (MPI) results exhibit that downstream of the river water is more polluted than upstream of the river. Overall, the findings of this study imply that polluted water is a threat to human health and the results will also help to undertake proper management strategies and incorporate monitoring programs that study river water for the implementation of safety measures to protect human health.

“…Recently, MCS has been successfully utilized to assess the health risk of riverine HMs. For instance, Emenike et al have found a relatively high carcinogenic/noncarcinogenic risk of Pb in the Atan district, Iran via MCS; Hasan et al and Karim et al also revealed a serious cancer risk in Bangladesh river by applying MCS. , However, this evaluation is still rarely reported in a typical urban river draining through metropolitan areas, which urgently requires a risk assessment for urban residents and pollution control strategy for reducing man-made HM contaminations. Land use changes has become more and more intense because of anthropogenic activities, which significantly influence ecosystem services .…”

The assessment of heavy metal (HM) distributions, sources, and potential risks is the first step of high-efficiency contaminant degradation and sustainable water resource utilization. In this study, the assessment of nine HMs from a typical urban river (Yongding River) in Beijing, China was implemented. Results evidence that the mean HM concentrations decreased in order: Mo > V > As > Zn > Ni > Mn > Fe > Cr > Co. The concentration of As, Zn, Mn, Fe, and Mo has a significant increase in the middle reaches, indicating agricultural and industrial pollution sources nearby. Three factors were extracted via principal component analysis, suggesting that As, Ni, Co, Mo, and V are mainly derived from anthropogenic inputs. Mn and Cr likely originated from natural sources, while Fe and Zn stemmed from mixed origins. The HM contamination levels are moderate and concentrated on As and Cr. Strong correlations among HMs and regional land use also confirmed the result. The noncarcinogenic and carcinogenic risks of HMs were evaluated based on four age groups by Monte Carlo simulation. Although the results of environmental modeling revealed a weak carcinogenic risk of As in adults (6.20 × 10–5), the risk for juveniles cannot be ignored. Target hazard quotients analysis implied relatively low noncarcinogenic risk when consuming fish tissues from rivers, and the carcinogenic risk of inorganic As in fish was acceptable. In total, this study provided powerful support for restoring HM contaminations and maintaining sustainable urban water management.
