ГРАМОТИ XIV–XV СТ. ЯК МАТЕРІАЛ ДЛЯ ВИВЧЕННЯ ІСТОРІЇ СТАНОВЛЕННЯ ЧИСЛІВНИКА В КУРСІ «ІСТОРИЧНА ГРАМАТИКА УКРАЇНСЬКОЇ МОВИ»
Authors: Бичкова Тетяна
Published: May 2022

У статті йдеться про важливість залучення в курсі «Історична граматика української мови» ілюстративного матеріалу з грамот XIV – XV cт., зок-рема під час вивчення теми «Історія становлення числівника». Запропоно-вано варіанти вправ і завдань із використанням прикладів з текстів грамот. При цьому наголошено на важливості наведення не окремих словоформ, як це узвичаєно в більшості підручників та навчальних посібниках з істо-ричної граматики, а мікроконтекстів, які сприяють кращому розумінню особливостей функціонування числівників у староукраїнській мові. Багата на числівники мова українських грамот також дає змогу формулювати за-вдання, що покликані «відволікти» студентів від суто граматичного аналі-зу (наприклад, визначити, яку кількість позначають дробові утворення з полъ, з’ясувати рік написання грамоти тощо). Зроблено висновок, що за-лучення текстів грамот XIV – XV ст. як дидактичного матеріалу на занят-тях з історичної граматики української мови сприяє кращому розумінню історичних мовних процесів і свідчить про нерозривний зв’язок історії мо-ви з історією українського народу.

Озиме жито є перспективною культурою для зони Полісся України, тому пошук та розробка ефективних і безпечних підходів і засобів для стимуляції росту та розвитку цієї культури є актуальним. Матеріалом дослідження було насіння озимого жита (Secale cereale L.) сортів Синтетик 38 і Забава та композиції метаболічно активних речовин, таких як: вітамін Е (10-8 М), параоксибензойна кислота (ПОБК) (0,001 %), метіонін (0,001 %), убіхінон-10 (10-8 М) і MgSO4 (0,001 %), які використовувалися у поєднаннях: вітамін Е+ПОБК+метіонін, вітамін Е+ПОБК+метіонін+MgSO4, вітамін Е+убіхінон-10. Проводили передпосівну обробку насіння досліджуваними композиціями. Дослідження проводилися у таких фазах розвитку жита: кущіння, трубкування, колосіння, цвітіння та молочної стиглості. Досліджувані композиції метаболічно активних сполук ефективно стимулюють ріст рослин озимого жита сортів Синтетик 38 і Забава протягом фенологічних фаз розвитку. Найбільший стимулюючий ефект спостерігається у фазі кущіння. Більше спостерігається приріст маси стебла порівняно з висотою у групах рослин із передпосівною обробкою композиціями вітамін Е+ПОБК+метіонін+MgSO4 та вітамін Е+убіхінон-10. Протягом досліджуваних фенологічних фаз розвитку у групах рослин обох сортів із передпосівною обробкою досліджуваними композиціями зростає довжина, маса та кількість коренів. Найбільший стимулюючий ефект демонструє композиція вітамін Е+ПОБК+метіонін+MgSO4. Отримані результати можуть свідчити про зростання ефективності функціонування кореневої системи, що і забезпечує ріст рослини. У роботі вперше досліджено вплив композицій метаболічно активних сполук, а саме вітаміну Е, убіхінону, параоксибензойної кислоти, метіоніну та MgSO4 на процеси росту надземної та підземної частин рослин озимого жита сортів Синтетик 38 і Забава та продемонстрована найбільша ефективність композицій Е+ПОБК+метіонін+MgSO4 та вітамін Е+убіхінон-10 щодо стимуляції росту як надземної, так і підземної частин рослини обох досліджуваних сортів.
ЗАГАЛЬНИЙ І АКТИВНИЙ СИМБІОТИЧНИЙ ПОТЕНЦІАЛ ГОРОХУ ПОСІВНОГО ЗАЛЕЖНО ВІД ТЕХНОЛОГІЧНИХ ПРИЙОМІВ В УМОВАХ ЛІСОСТЕПУ ЗАХІДНОГО

Published: May 2022

У статті висвітлено результати щодо формування загального і активного симбіотичного потенціалів гороху посівного залежно від рівня удобрення різними дозами мінеральних добрив та регуляторів росту в умовах Лісостепу західного. Фактори, які вивчалися впродовж 2016–2018 років, мали позитивний вплив на розвиток і формування нодуляційного апарату в рослин гороху сучасних сортів. Мета експериментальних досліджень полягала у виявленні особливостей впливу різних доз мінеральних добрив та регуляторів росту на формування нодуляційного апарату на коренях рослин гороху посівного. Встановлено, що симбіотична система зернобобових культур залишається активною протягом усіх фаз росту та розвитку. Біологічний азот, який засвоюється коренями упродовж періоду вегетації бобових культур, зокрема й гороху посівного, екологічно безпечний та значно поліпшує родючість ґрунту. Польові досліди закладали на чорноземах типових глибоких малогумусних важкосуглинкових на лесовидних суглинках, у десятипільній сівозміні Навчально-виробничого центру «Поділля» Подільського державного аграрно-технічного університету. Упродовж років досліджень вивчали дію та взаємодію трьох факторів, як-от: А – сорт (Готівський (контроль), Фаргус та Чекбек); В – удобрення (P30K45 (контроль), N15P30K45, N30P30K45, N45P30K45); С – регулятори росту (контроль – без обробки, Плантапег – 25 г/га, Емістим С – 30 мл/га, Вимпел – 30 мл/га). Доведено, що внесення невеликих доз мінеральних азотних добрив на фоні фосфорно-калійних покращувало біологічну фіксацію азоту в рослин, які обприскували регуляторами росту. У наших дослідженнях показники загального симбіотичного потенціалу перевищували показники активного, адже загальна кількість бульбочок та їхня маса були більшими від кількості і маси активних бульбочок. Найвищими ці показники зафіксували на коренях рослин гороху сорту Чекбек, де вносили мінеральні добрива в дозах N30P30K45 у комплексі з регуляторами росту. Найвищі дози мінерального азоту N45 негативно впливали на рівень загального й активного симбіотичного потенціалів, що в кінцевому результаті призвело до зниження врожайності зерна гороху.
Tilt-Up Partially Composite Insulated Wall Panels
Authors: Maguire Marc , Al-Rubaye Salam
Published: May 2022

This research project was initiated to investigate the behavior of load-bearing concrete insulated wall (CIP) panels for use in tilt-up construction. The primary objective was to understand the inelastic behavior of these panels so that engineers could perform a proper second-order analysis for combined axial and out-of-plane loading. Toward this aim, the Tilt-up Concrete Institute (TCA) and wythe connector suppliers Innstruct, Thermomass, HK Composites, Dayton Superior, and IconX, funded this study.
Since tilt-up panel testing of similar scope had not been done since the 1980s on panels of lower height, there were several goals for this testing. This represented an opportunity to validate the current ACI code alternate slender wall analysis method and provide a set of control panels for testing solid tilt-up panel behavior. Testing solid panels and CIPs of 40 ft span, a length typical of contemporary construction, was critical so that such slenderness ratios could be observed and significant second-order panel behavior could be identified.
As part of this, the research team created a modified version of the slender wall design method to predict second-order load and deflection behavior in the post-cracking range in CIPs. For solid panels, the 1980s testing program popularized the “slender wall design method” outlined in ACI 551 and the goal of this newer methodologies is to do the
same for CIPs. Additionally, horizontal shear failure analysis methods were investigated to enable design against such failures.
Single; thus, homeless forever? Inaccessibility and precarity of housing for single Indigenous women living in the Northwest territories: a policy review of the local housing organizations (LHOs) Tenant Relations Manual - 204 - Point rating of applications
Authors: Doyle Shannen
Published: May 2022

In the Northwest Territories (NWT), a point-rate system is administered by the Northwest Territories Housing Corporation (NWTHC) to ensure that households in greatest need for public housing are given priority access. This priority is often given to families with children, persons with disabilities, or seniors. This often leaves non-prioritized populations like single individuals without children limited access to public housing units, and in a state of housing precarity. In the NWT, housing precarity is experienced inter-sectionally; as race, gender, and household composition play a large role in public housing eligibility. Among these at-risk populations, single Indigenous women (SIW) face disproportionate barriers to accessing public housing. This paper argues that barriers to housing access are in part due to colonial, patriarchal, and paternal ideologies that have historically become embedded within housing policy and contributed to the disenfranchisement of SIW in public housing. Through a policy review of the LHO Tenant Relations Manual – Point Rating of Applications, this paper will call for gender-specific and cultural-specific policies and programs in order to effectively acknowledge the lived experiences of SIW accessing public housing policy in the NWT.

Urban cycling equity : an analysis of equity based approaches in public bike sharing program development in Toronto
Authors: Mekonnen Gelila
Published: May 2022

The prominence of bike sharing programs as an alternative mode of green transportation has captured the attention and stimulated renewed enthusiasm among urban cyclists, municipalities, and urban planners alike. However, researchers and critics question the distributive effects of these services on marginalized communities. When examined closer, studies demonstrate that bike share users have on average, a high education status, work full time, and have high incomes. Moreover, older adults, women, and low-income communities remain marginally represented in bike share user demographics throughout major North American cities. In recognition of these observations, this Major Research Paper (MRP) explores how these equity considerations are relevant to Bike Share Toronto (BST), the City of Toronto’s publicly-owned bike share program. This analysis uses mixed method research including spatial analysis of the existing BST service area, an analysis of BST Equity Survey results, and expert interviews with representatives with key institutional perspectives on bike share equity. Finally, this research highlights key considerations relevant for the development of a bike share equity intervention by BST.

Preparation for nursing student placements abroad and in Canada's northern communities: a secondary analysis
Authors: Poulter Tyler
Published: May 2022

Service-learning experiences, or undergraduate nursing placements, are being pursued by students to gain a global perspective and broaden their cultural horizons in preparation for the increasingly diverse realities of the world. And yet, a paucity of literature exists in how to best prepare nursing students to practice from a position of cultural safety. The purpose of my study was to examine how structure and agency shaped nursing students’ preparation for placements abroad and in Canada’s Northern communities. A secondary analysis was employed to examine pre-existing qualitative data in the form of previously conducted interviews. Giddens’ Structuration theory was utilized to understand the (re)production of social systems based on the duality of structure and agency. Findings indicated that students’ perception and how they experienced their environment impacted their actions, thus, illustrating the need to improve predeparture training to be rooted in cultural safety. Implications for practice, education, and policy are explored.
Auto: The Ethics Of Machine Learning Algorithms & Autonomous Vehicles
Authors: Furlin Stephan
Published: May 2022

This thesis aims to address what I hold to be the most pressing ethical issues in autonomous vehicles. Chapter one focuses on the applicability of moral philosophy in guiding autonomous vehicle regulation. Chapter two highlights the need for “explainability” in machine learning algorithms in order to ensure that autonomous vehicles are fair and rights-respecting, and the need for a change in regards to distribution of liability for driving behavior. Chapter three asserts that laws regarding liability must be altered in order to keep pace with the changes in driver responsibilities which come with less direct control of the vehicle.
Assessing the Effect of the King Street Transit Pilot on Residential Traffic Noise Exposure
Authors: Connor Cody
Published: May 2022

The noise in urban environments continues to grow as more of the world's population transitions to cities. Vehicular noise is one of the main factors of noise pollution in cities. Toronto recently introduced a Transit Priority Corridor which reduced the total traffic flow along one major road. High levels of noise can have serious health impacts on city residents who work and live in dense urban cores. This study aims to model the noise on the façades of buildings in the City of Toronto. Two models were created using traffic flow data modelled from measured vehicle counts. SoundPlan a noise modelling software, was used to create façade level noise maps and to estimate the residential exposure. In the study area surrounding King Street, over 90% of the population in the study area was found to be exposed to levels described by the World Health Organization as dangerous. In the study area, 91.66% of the population based on the modelled results was exposed to levels above 45 db(A) before the pilot and 92.45% were exposed after the pilot. Noise disturbance at this level is associated with many long-term health impacts that can be mitigated by reducing source noise. Transit efficiency management systems like the King Street Pilot program can be used to reduce source noise although programs along only one stretch or road are unlikely to significantly reduce noise levels
Land-use regulation and housing affordability: characterizing the impacts of restrictive zoning on Toronto's housing market through a case study of Ward 8 neighbourhoods
Authors: Pal Nicole
Published: May 2022

Toronto’s housing affordability crisis continues to escalate. Increasing demand and land supply constraints prevent the housing and land market from reaching equilibrium, resulting in skyrocketing house prices and a disproportionately small number of additional units built. Despite efforts from City Council to increase affordable housing options, housing affordability concerns have yet to be adequately addressed. By collecting and analysing the market, zoning, and minor variance/consent data in Toronto’s Ward 8 neighbourhoods, this MRP argues that much of Toronto’s inner-suburban neighbourhoods contain overly restrictive land-use regulations that may worsen housing affordability and perpetuate suboptimal land values. The most restrictive areas and neighbourhoods appear to be experiencing the greatest effects of supply constraining regulations, as they have the highest growth in house prices, the greatest increase in housing services per unit upon rebuild, and disproportionately low per-square-foot property values in comparison to its sale price. This MRP also finds that community and institutional support for new development in Toronto’s neighbourhoods are contingent on conformity with existing physical neighbourhood character, whose definition favours the detached home. To help ease the housing affordability crisis, it is recommended that Toronto encourage a range and mix of housing typologies by removing policies and regulations that reinforce single-family only neighbourhoods
Finding the missing middle: the potential and capacity for missing middle growth in Toronto
Authors: Bailey Daniel Robert
Published: May 2022

Interest in and action to add missing middle to cities across North America has seen a recent
increase, with mixed success. Toronto City Council has recently requested a staff report on
potential ways to add different housing options to Toronto’s neighbourhood, suggesting
changes may be in progress here. Missing middle has the potential to reduce Toronto’s reliance
on mid/high-rise apartments for new housing, and create more housing supply especially for
middle-income family households. The need for and impact of regulatory changes must be
evaluated to create appropriate reforms and communicate them with stakeholders and the
public. This research paper provides initial housing type growth projections, maximum densities
for housing typologies, and upper limits on the capacity of missing middle to add housing to
Toronto’s neighbourhoods.

Published: May 2022

Introduction: Domestic violence is a serious and preventable public health issue. Student Training on Preventing Domestic Violence (STOP-DV) is an extracurricular program that educates medical students on domestic violence. This study sought to determine if STOP-DV is an effective method to increase the knowledge of domestic violence among medical students.

Methods: This study utilized a quasi-experimental research approach. Participants were recruited through a convenience sample of first- and second-year medical students from an osteopathic medical school with three campuses. The intervention group included the campus where STOP-DV was implemented and was then compared to the control group (the other two campuses) without the program. Intervention and control groups were given the same pre-survey and post-survey to assess for baseline knowledge, awareness, self-efficacy and health-seeking behaviors. Bivariate and multivariate statistical analysis of matched pre-surveys and post-surveys was completed during the 2018 and 2019 school year.

Results: Medical students in the intervention group (n=100) showed a statistically significant increase in self-efficacy and in the ability to recognize domestic violence in patients (p<0.001) and to discuss domestic violence with patients (p=0.004) compared to the control group (n=47). Based upon general linear regression analysis, survey stage significantly contributed to participants self-efficacy and domestic violence knowledge in both cohorts. Additionally, intervention group significantly contributed to participants’ medical domestic violence knowledge.

Conclusions: This study was successful in implementing a domestic violence program and increasing awareness in medical students. The ultimate goal is to encourage schools to utilize a similar program to understand how domestic violence affects patients and their communities.
Generalized eigenvectors of linear operators and biorthogonal systems
Authors: Khats' Ruslan
Published: May 2022

The notions of a set of generalized eigenvalues and a set of generalized eigenvectors of a linear operator in Euclidean space are introduced. In addition, we provide a method to find a biorthogonal system of a subsystem of eigenvectors of some linear operators in a Hilbert space whose systems of canonical eigenvectors are over-complete. Related to our problem, we will show an example of a linear differential operator that is formally adjoint to Bessel-type differential operators. We also investigate basis properties (completeness, minimality, basicity) of the systems of generalized eigenvectors of this differential operator.

Background: Radioiodine therapy is very effective and popular method of choice for the treatment of carcinoma thyroid. Dry mouth is acommon side effects after radioiodine therapy and sequel of the salivary gland dysfunction. Many of the patients are suffering from this side effect. This study was designed to evaluatethe functionof the salivary gland of the patients treated with radioiodine therapy.
Materials and methods: This cross sectional study was done in the Institute of Nuclear Medicine and Allied Sciences Mitford Dhaka for about 06 months from August 2019 to March 2020. About 51 patients were enrolled for this study having single dose of radioiodine therapy. Dynamic sialo scintigraphy with citrus stimulation was done after intravenous injection of 02 mci of Tc-99m. After 10 minutes of dynamic study lemon juice was given orally for the augmentation of the gland function. Result was interpreted as salivary gland dysfunction when a curve was uprising after lemon juice augmentation and normal functioning when fall off curve. Then data were compiled and analyzed by SPSS version 22.
Results: The mean age of the study subjects were 35.1 ± 9.8, age ranged from 14~56 years, sixwere male and 45 were female participants. The mean dose was 4.3±1.1GBq, ranges from 1.8~7.4GBq. The proportion of salivary gland dysfunction was 60.8% while 39.2% had normal salivary gland function.Right salivary gland dysfunction was found in52.9% patients while 54.9% patient showed left salivary gland dysfunction. A little above a decile (13.7%) showed right submandibular gland dysfunction while a little less than that(7.8%) showed left submandibular gland dysfunction. Salivary gland dysfunction was related to the dose of the radioiodine therapy (p<0.5). Higher dose of RAIT produced the odds of dysfunction in right parotid gland as 1.01, that of left parotid as 0.04, that of right submandibular as 0.09and that of left submandibular 0.60.
Conclusion: Higher dose of radioiodine therapy was related with salivary gland dysfunction

Intramuscular hemangiomas are rare neoplasms of blood vessel origin located inside muscles, which may not be clinically apparent at presentation. We present one such interesting case which was deceiving enough to remain unnoticed on initial short clinical examination and produced a misleading cytological diagnosis up front. High resolution ultrasound gave a clue to the diagnosis of the tumor. More specific radio-labelled RBC scan confirmed its presence, while fusion imaging pin-pointed its location.

The St. Martin’s Island, the only offshore coral island in Bangladesh depends on solely groundwater for domestic uses. This study finds that groundwater occurs between 1m and 7m depths within four different aquifer lobes distributed throughout the island. These lobes are formed by deposition of beach sands within bedrock depression and are completely isolated from the influence of sea water. The model simulated groundwater budget for one of the lobes suggests that 11% of total dynamic reserve is used for water supply to local inhabitants and seasonal tourists and the rest is lost due to evapotranspiration and seepage along the boundary of the aquifer. The chemically suitable quality of potable groundwater prevails throughout the island but presence of Escherichia coli in the groundwater samples of the island possesses a great health threat. E. coli is found in 58% and 44% of the groundwater samples during dry and wet season, respectively. The unplanned construction of resorts and their septic tanks within the aquifer are responsible for the pathogenic contamination of groundwater in the St. Martin’s Island. Although currently there is no threat of seawater intrusion, the rise of sea level over the bedrock barrier and storm surge inundation may destroy this resource in near future.

Published: May 2022

The COVID-19 pandemic has snatched away the lives and livelihoods of many people throughout the world. The number of infected and death from SARS-CoV-2 has still been increasing in Bangladesh. The fear of the unknown, uncertainty, knowledge gap and high communicability have fed into the social stigmatization of COVID-19 patients and survivors. Considering the research gap, this study looks at how stigma and prejudice caused by COVID-19 are prevailing in Bangladesh. This research was carried out on purposively chosen 200 COVID-19 positive patients who were hospitalized in a government-run COVID-19 dedicated hospital in Dhaka from the end of March 2020 to August 2020. All ethical concerns were maintained during data collection. The qualitative approach was used for in-depth interviewing through telephone. The present study finds some phenomenal examples and experiences of marginalization and stigmatization due to the highly contagious nature of the virus among the patients, relatives, neighbors, health care workers etc. COVID-19 patients or their relatives are found to pass muchstigmatized life with a feeling of hopelessness. Even though many of the COVID-19 patients died, their family members are still bearing the brunt, making them stigmatized. The discourses of self-stigmatization, social harassment, treatment, prejudice, and stigmatized funeral etc., have been discussed critically.

Structural Interpretation of 3D Seismic Data of a Passive Rift Margin: A Case Study of Bellatrix Basin
Authors: Lupin Janifar Hakim
Published: May 2022

The Bay of Biscay is considered France’s most prospective offshore region, but a complex geodynamic history has so far hindered its development. The landward side of the Parentis Basin has significant oil shows in late Barremian Limestones and early middle Jurassic dolomites. The offshore extension however has a thicker depocentre with a contrasting burial history resulting in plays more difficult to define – dampening drilling enthusiasm to date. Although the basin remains poorly understood this study has found the evidence of petroleum potential. Due to somewhat limited well control the risk remains a significant factor in further exploration. A maturity window in the Early Cretaceous has suggested targeting of more subtle structural and robust stratigraphic intervals on the footwall block could potentially be prospective. This study would recommend a rigorous 3D basin modeling project (outside the scope of this study) and acquisition of minimum 2D seismic between the existing block and onshore Parentis fields – this would allow better understanding of the transitional structure and subsequently the disparity in burial history/charge timing.

The Jamalganj coalfield with the coal deposits of the Permian Gondwana Group in the halfgraben basin was discovered in Joypurhat District, Northwestern Bangladesh, sometime in 1962. Individual coalbed thickness ranges from 0.60 m to 42 m and seams were encountered between the depth ranges of 640 m and 1158 m. Since mining has not yet begun due to the greater depth of the coal seams, several researchers have proposed a Coalbed Methane (CBM) exploration in this region. This research focuses on the permeability of the Jamalganj coal derived from the in-situ Injection Falloff Test (IFT), which is an important reservoir parameter and one of the key factors in CBM exploration and Underground Coal Gasification (UCG). In addition to that, the relationship of temperature and skin factor with permeability is one of the key findings of this research, permeability obtained from the IFT ranges from 2.57 to 121.16 mD while the skin factor ranges from - 6.11 to 50.85 and a higher temperature gradient as of about 4°C per 100 m depths was observed. The study shows that temperature has an inverse relationship with the permeability that decreases with depth and temperature increases, which is analogous with the other CBM producing reservoirs around the world. The negative skin factor denotes flow enhancement near the wellbore and a well-stimulated reservoir, and the positive skin factor indicates increased flow resistance near the wellbore, which reduces permeability. The permeability data suggest that the analyzed coal seams of the Jamalganj Coalfield are suitable for unconventional gas production by either CBM or UCG development.

The present study assesses the proximate composition of eight wild seaweed species viz. Hypnea sp., Enteromorpha sp., Sargassum sp., Hydroclathrus clathratus, Padina pavonica, Colpomenia sinuosa, Petalonia fascia and Dictyota ciliolata and one cultured species viz. Hypnea sp. collected from western coast of the St. Martin’s Island and Nunairchhara, Cox’s Bazar, respectively. Standard analytical methods were used to estimate moisture, ash, lipid, crude fiber and protein contents, while carbohydrates were measured by subtracting ash, fat, fiber and protein contents from 100 on a dry weight basis. Results showed average moisture content in different seaweed species ranged between 12.09% to 29.65% and varied from species to species. Maximum ash content was found in brown seaweed H. clathratus (61.98%), while the lowest was recorded in wild red algae Hypnea sp. (7.05%). This study showed mean lipid contents in all seaweed species were much lower than other contents of proximate composition. The highest crude fiber content was observed in P. fascia (10.08±0.07%), while the lowest was observed in Enteromorpha sp. (0.23±0.01%). The highest protein (23.64±1.44%) and carbohydrate content (46.71±0.54%) was found in Hypnea sp. This study showed that mean carbohydrate content was higher in Rhodophyta, Chlorophyta and Phaeophyta, whereas, lipid content was lower in the three groups. Proximate composition of ash, lipid, crude fiber and protein content within species varied due to habitat differences, changes of body structures or physiological alterations, changes in growth rates and photosynthetic function of seaweed species and geographical differences. The mean moisture and ash content were the highest in cultured Hypnea sp., whereas, lipid, crude fiber, protein and carbohydrate were formed to the highest in wild Hypnea sp. Results suggest wild Hypnea sp. was much nutritive because of having higher amount of protein, fiber, carbohydrate and lipid than cultured ones. The study indicates that seaweeds might be used as a potential source of protein, fiber and carbohydrate.

Published: May 2022

Rapid industrial development and negligible waste disposal management are considered the driving factors for the major environmental crisis in developing countries like Bangladesh. In the present study, the surface water of Meghna River estuary was evaluated for the concentrations of five toxic heavy metals, namely chromium (Cr), lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg). All the heavy metals in question were found to be higher than the background value of natural surface water. The toxic heavy metals were in the descending order of Pb>Cr>Hg>Cd>As in the collected water samples. Pb and Hg were found to exceed the lowest biological chronic safety concentration limits recommended by the National Oceanographic and Atmospheric Administration (NOAA), whereas Cr, Cd, and As were under the admissible limits. Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), and Pearson’s correlation analysis suggested that the sources and distribution of those toxic heavy metals are similar. Anthropogenic activities such as industrial waste, agricultural runoff, and municipal solid waste disposal may be responsible for the increased concentration of those metals. Compared to China’s secondary seawater quality standard, the concentration of heavy metals in the Meghna estuary is considerably higher, except arsenic. When compared with previous studies, the heavy metals concentration in the Meghna estuary is significantly higher, which is alarming. From this integrated study, the Meghna estuary is under threatening conditions from ecological and human health perspectives. Further studies are required for temporal monitoring and assessment of the Meghna River estuary.
