Abstract The heavily industrialised Kanpur region is the most polluted stretch of Ganga river because excessive pollutant discharge from industries. Agricultural runoff along with climate change further adds to pollution risk in this Ganga. In paper, we analyse potential impacts and land use on water quality under hypothetical scenarios using model, QUAL2K. Water indicators Dissolved Oxygen (DO), Biochemical Demand, ammonia, nitrate, total nitrogen, organic-, inorganic- phosphorous faecal coliform are assessed for eight six cover scenarios. Eutrophic conditions observed all scenarios, implying severe aquatic life. DO identified as sensitive indicator considered, while nutrients more Increase agricultural area leads larger nutrient concentration increase built-up causes an concentration. Results study could provide valuable guidance improving Ganges future

Metal contamination in surface water urban cities has become a common scenario underdeveloped and developing countries. Nowadays, the extent of this is suspected to be traced remote islands due transportation metals with downward flow. Unfortunately, we found dearth research on our island, where thousands people live use for their daily needs. The current study aims investigate status heavy from Hatiya Coast, determine existence risks human health. Ten samples were collected, concentrations measured using AAS. Later, various pollution indices analyzed understand level. mean metal ranked descending order Mg (65.44 mg.L−1)> Fe (0.375 Zn (0.139 mg.L−1)>Mn (0.016 Cu was below detection limit (BDL). According different indexes, coast low moderately polluted. standard HEI value 1.58, range 1.29-2.25, indicating that all sampling stations had level contamination. HPI values at 44.58 34.33-69.33, respectively. All indicated levels except station 6. NPI revealed moderate 2, 3, 7. hazard quotient (HQ) index (HI) adults children, have no carcinogenic children through dermal exposure. Along coming upstream, several local sources identified during fieldwork, including metallurgical businesses, oil spills ship, some trawlers associated fishing activities. Overall, these findings would valuable aquaculture sectors future researchers compare, correlate, island serve as foundation conducting further investigations similar environments, both locally globally.

Groundwater meets the majority portion of drinking water needs, particularly in rural area Bangladesh.Groundwater has been continuously contaminated by potentially harmful metals as a result natural processes well some anthropogenic activities, creating variety health impacts.The current research aimed to evaluate naturally occurring level metal contamination and human risk associated with deep groundwater Hatiya Island.Because arsenic, iron, salinity problem shallow groundwater, inhabitants Island use groundwater.During field investigation, no tubewells were observed; therefore, only samples collected.The total sample size collected throughout island was 17.Five (Zn, Fe, Mg, Mn, Cu) analyzed using an Atomic Absorption Spectrophotometer (AAS).The concentrations studied potential risky ranked follows: Mg > Zn Fe >Mn> Cu.The detected values all except found within limits WHO (2017), BIS (2012), BDWS (1997), where 29.41% exceeded standard limits.According evaluation index (MEI) degree (C d ), study is free from but pollution (MPI) nemerow (NI) exhibited little mid-western part area.The hazard quotient (HQ) revealed oral dermal for individual (Cu, Zn, Mn).On other hand, (HI) combined none safety limit value 1.According HQ HI results, on non-carcinogenic risk-free children adults.However, more susceptible risks than adults.In contrast, adults vulnerable children.
