Hydrochemical Characterization and Quality Assessment of Groundwater in Hatiya Island, Southeastern Coastal Region of Bangladesh

Water, Journal Year: 2023, Volume and Issue: 15(5), P. 905 - 905

Published: Feb. 26, 2023

Groundwater is a vital source of fresh water for drinking and agricultural purposes in the region Hatiya Island, Bangladesh, yet it subject to contamination by natural anthropogenic activities. Over time, has resulted variety negative effects on human health. This research aims examine groundwater hydrogeochemical characterization suitability irrigation different indices utilizing combined geochemical method, multivariate statistical approaches, geospatial analysis. Results analyses 15 samples from intermediate aquifer (60–90 m depth) represent order cations, anions, metal concentrations as Na+ > Mg2+ Ca2+ K+, Cl− SO42− HCO3− NO3−, Fe I Br Mn As, respectively. Saltwater intrusion been determined be most important process influencing chemistry groundwater. Principal component analysis, Pearson’s correlation matrix, hierarchical cluster analysis indicate that quality highly governed geogenic influences. information evaluated using index map, which found six (40%) are suitable consumption, whereas other nine (60%) unfit drinking. The parameters revealed eight (54%) excellent or good condition uses; however, seven (46%) unsuitable.

Is the groundwater of Dhaka city, Bangladesh contaminated with naturally occurring potential toxic elements?

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 12

Published: Jan. 6, 2025

This study investigates the contamination of groundwater in Dhaka City, Bangladesh, focusing on six potentially toxic elements, including As, Cu, Mn, Cr, Al, and B, due to their implications for public health as serves primary source drinking water region. 15 samples were taken into consideration was analyzed elements (As, B) using an Atomic Absorption Spectrophotometer (AAS). Arsenic (As) chromium (Cr) undetectable all samples. The average concentrations Copper (Cu), Aluminum (Al), Boron (B), Manganese (Mn) measured at 0.075 mg/L, 0.087 1.14 0.48 respectively. Among these, only one sample (S-05) exceeded WHO (2022) limits Boron, 10 surpassed Manganese. Pollution indices like MEI, NI, Cd used evaluate levels, revealing significant pollution multiple Metal evaluation index (MEI) values found between 0.39 17.97 with 6.71. Nemerow (NI) degree (C d ) sequentially be 4.35 5.71. In both cases, eight highly contaminated. observed hazard (HI) adults varied from 0.20 2.47, whereas children it ranged 0.32 3.93. All indicate exceed HI which indicates that are more susceptible than through oral exposure water. elevated manganese cause higher Cd, highlights a critical concern advocates need mitigation efforts ensure safe access. underscores urgent implementing stricter management policies interventions mitigate risks.

Nutrient and heavy metal dynamics in the coastal waters of St. Martin’s island in the Bay of Bengal

Heliyon, Journal Year: 2023, Volume and Issue: 9(10), P. e20458 - e20458

Published: Sept. 27, 2023

Seasonal variation observations were conducted in the coastal waters of St. Martin's Island Bay Bengal to examine influence physical processes and distribution pattern nutrients ocean water. Pollution evaluation indices, health index statistical techniques incorporated assess heavy metal contamination. Two seasons, cool dry winter pre-monsoon hot, considered for sampling from 12 stations around island. The Cool season has higher nutrient concentrations than Pre-monsoon Hot season. concentration appeared as follows: Silicate > Nitrate Ammonia Phosphate Nitrite. PCA Pearson's Correlation showed that fresh water nearby rivers, deep upwelling, and, some situations, modest anthropogenic sources are crucial. Hence, low DO phosphate levels during hot indicate there is a planktonic process like photosynthesis prevailing. island's north-western south-eastern regions have concentrations, which may be seasonal due wind action. Pb, Cu, As, Cr, Cd, Zn also comprehend geo-chemical perspectives ecological human risks. Heavy Metal Index (HPI) Evaluation (HEI) demonstrated places much threshold limit, even though no significantly value was detected Nemerow Index, Total Ecological Risk (TERI), indicated contamination severe moderate moderate. Finally, correlation association between chemical characteristics, similar metals. Thus, this research help shed light on state seas Island. This study provide explicit insights authority take necessary measures preserve marine ecology associated terrestrial ecosystem.

This study assessed the extent of potential toxic element (PTE) contamination and its associated health risks in groundwater from Tista Floodplain, Rangpur, northern Bangladesh. A total 130 samples (65 wet season 65 dry season) were analyzed for six PTEs: As, Al, Cu, Mn, Cr, B using Atomic Absorption Spectrophotometry (AAS) VIS Spectrophotometry. The mean concentrations PTEs followed a decreasing order > Mn Cu Al As Cr season. Metal evaluation index degree indicated minor contamination, while Nemerow pollution showed moderate to severe especially Nilphamari district. Contamination levels higher compared No individual posed non-carcinogenic risks, but combined presented threats, particularly infants, with severity during dermal identified. Despite relatively low levels, monitoring policies new existing tubewells should be implemented ensure sustainable management long-term water quality.
