Abstract Heavy metal contamination in river Ganga is one of the factor for deterioration its water quality, also adds to human health risks. We designed our study achieve a holistic approach by not only estimating concentration heavy metals (Lead, Manganese, Chromium and Cadmium) at different sites based on anthropogenic activities but fishes residing same that are collected consumption daily basis. found, Varanasi highly loaded with (PLI = 6.698) Mean was: Pb 1.29 mg/L, Mn 1.325 Cr 0.169 mg/L Cd 0.161mg/L, which were above permissible limits stated Environment Protection Agency (EPA) drinking water. Fishes including exotic invasive species from wild processed presence these their living tissues. Degree followed liver > gills muscles. Highest accumulation was observed Carpio ( Cyprinus carpio) (8.86 µg/g) lowest Baikari (Clupisoma garua) muscles (0.07 µg/g). Total Target Hazard Quotient (THQ) value i.e. hazard index (HI) showed values following sequence: C.carpio O. nilotus C.punctatus J.coitor M.armatus M.tengara . Maximum HI recorded , consumed fish human, hence may be harmful them.

Functioning of coastal wetland habitats is essential for the ecosystem integrity and sustainability development that enables human progress along transitional waterways. However, these are continuously being affected by a variety pollutants including metallic elements. In this study, seasonal variation, pollution status ecological risks heavy metals (Cr, Mn, Co, Ni, As, Cu, Zn Pb) in surface sediment several types wetlands (estuaries, mudflats, sandy beaches, mangroves, saltmarshes) were detected using X-ray fluorescence (EDXRF) spectrometry. The results showed mean concentration level surficial samples followed order Cu (84.06 ± 8.60 μg/g) > (51.00 8.97 Mn (38.25 11.34 Cr (3.52 0.91 Pb (0.27 0.13 Co (0.24 As (0.21 0.12 Ni (0.16 0.08 μg/g). comparison to pre-monsoon period, post-monsoon season had higher concentrations while overall accumulation exhibited pattern estuarine (28.47 31.35 mangrove (22.23 30.79 mudflat (21.79 29.71 beach (21.47 28.15 saltmarsh (21.28 30.02 Although, assessment indices e.g., contamination factor (CF), degree (CD), geoaccumulation index (Igeo) load (PLI) minimal levels studied sites, enrichment (EF) suggested greater but with lowest risk (RI < 40) both seasons.

The major issue associated with coal mine drainage is its contribution to river pollution, which occurs at the local, regional, and global levels. pollution of surface sediment by heavy metals a environmental health concern in mining downstream areas. This study explored concentrations eight metal components sediments from Shari-Goyain River Bangladesh. trend decreasing concentration was identified as Fe > Mn Ni Zn Cu Cr Pb Cd sediment. level area assessed using various indicators like geo-accumulation index (Igeo), load (PLI), contamination factor (CF), potential ecological risk factor, (RI). exhibited PLI values ranging 0.133 0.543, suggesting low evaluated (PLI < 1). mean Igeo showed that unpolluted whereas moderately polluted status. For most metals, samples recorded degree (CF 1) except Pb, Cd, moderate (1 ≤ CF 3). Through application statistical analyses, has been possible source analyzed River. However, RI suggested studied To improve conditions River, it crucial construct permanent quality monitoring stations conduct extensive investigations.

The Yihe River is the largest mountain torrent river in Shandong Province, which plays an important role flood control, irrigation and climate regulation. Due to impacts of upstream urban domestic sewage, as well industrial agricultural wastewater, Linyi City section expected have a high risk metal pollution. Sediments are main reservoir potential release source metals (metalloid) systems. Assessment sediments can identify anthropogenic In this study, 25 sediment samples were collected from its tributaries, concentration As, Cd, Cr, Cu, Ni, Pb Zn quantified by inductively coupled plasma mass spectrometry (ICP-MS), Hg was determined atomic fluorescence (AFS). pollution levels evaluated determining contamination factor, load index, geoaccumulation ecological assessment toxicity index. Correlation analysis absolute principal component-multiple linear regression (APCS-MLR) used conduct apportionment. Pb, Zn, detected all samples. Overall, stream mostly within environmental background value, overall state no slightly polluted, while tributaries polluted state. Cd two pollutants surface study area, with average content 1.65 1.11 times respectively. Most areas free pollution, low risk. risks (Suhe River, Benghe Liuqinghe River) center island (Yihe North Island) assessed presenting toxicity. Source showed that As mainly come natural sources activities, result transportation industry. results help us understand distribution sediments, also provide management support local departments relevant national departments.

The global concern over trace and heavy metal contamination in aquatic environments necessitates the development of effective remediation strategies. Using plants for removal is a relatively economical sustainable technology worldwide. This study involved collecting sediment plant samples (Acanthus ilicifolius, Typha elephantina, Cynodon dactylon) from highly urbanized estuary to analyze concentrations sediment, assess ecological risks, explore phytoremediation potential. Trace metals were detected using Energy Dispersive X-ray Fluorescence Spectroscopy (EDXRF). found decreasing order Fe, Ti, Mn, Rb, Zr, Zn, Sr, Cu, Co, As. As below certified values, whereas Rb exceeded them. Cumulatively, pollution load index (PLI) values close 1 (0.845), indicating that area likely experiencing pollution. Contamination Factor (CF) ranging 3, indicated moderate degree Rb. Enrichment (EF) similarly showed enrichment these metals, with Cu exhibiting highest enrichment. Ecological risk assessment highlighted only metal, as posing greatest among studied metals. In terms potential, bioconcentration factor (BCF) followed C. dactylon > A. ilicifolius T. elephantina most low BCF (<1) accumulator However, translocation (TF) Zn (1.464) (1.299) species greater than 1, accumulation potential but hyper-metabolizing capabilities, allowing accumulate its aerial parts, making it phytostabilization.
