Hydrogeochemical characterization and quality assessment of groundwater resource in Savar - an industrialized zone of Bangladesh.

Savar Upazila in the Dhaka District is a rapidly expanding city with a diverse range of industries and agricultural activities. This expansion poses environmental challenges including the threat to groundwater contamination. Based on these considerations, the objective of this research is to carry out a shallow groundwater hydrogeochemical characterization and an assessment of the suitablity of the groundwater for drinking and irrigational purposes using a geochemical approach, multivariate statistical techniques, and some indices of groundwater quality.

The analysis and accuracy of mortality prediction scores in burn patients admitted to the intensive care burn unit (ICBU).

Background: To date, multiple scoring systems have been utilised in predicting outcomes in burn patients. The aim of this study is to determine the accuracy of three established scoring systems used for burn patients admitted to the intensive care unit and to determine the risk factors associated with poor outcomes.

Methods: A total of 211 patients who were admitted to the ICBU in a tertiary care centre in Kuwait from January 2017 to December 2019 were analysed retrospectively.

Child lead exposure near abandoned lead acid battery recycling sites in a residential community in Bangladesh: Risk factors and the impact of soil remediation on blood lead levels.

Lead is a potent neurotoxin that is particularly detrimental to children's cognitive development. Batteries account for at least 80% of global lead use and unsafe battery recycling is a major contributor to childhood lead poisoning. Our objectives were to assess the intensity and nature of child lead exposure at abandoned, informal used lead acid battery (ULAB) recycling sites in Kathgora, Savar, Bangladesh, as well as to assess the feasibility and effectiveness of a soil remediation effort to reduce exposure.

Did Prophet Mohammad (PBUH) have epilepsy? A neurological analysis.

Introduction: The Prophet of Islam is one of the several famous religious figures who allegedly suffered from epilepsy. Early Greek chronicler Theophanes was one of the first to mention that the revelations of The Prophet were episodes of epilepsy, sparking a debate that has continued to date. This argument, for the most part, was confined to historic literary writings only until it was quoted by some eminent neurologists of recent times.

Epilepsy treatment gap and stigma reduction in Pakistan: A tested public awareness model.

High epilepsy treatment gap (ETG) and stigma remain a major issue globally. Addressing the basic problems is necessary, for advances in management to be effective. According to the 1987 population-based study, prevalence of active epilepsy in Pakistan is 0.

Anemia and iron deficiency in rural Bangladeshi pregnant women living in areas of high and low iron in groundwater.

Background: Recent studies found a low rate of iron deficiency in Bangladeshi non-pregnant and non-lactating women. This was attributed to high iron concentrations in drinking water. However, there are limited data on iron deficiency among pregnant women in Bangladesh.

Toxicity assessment of ash and dust from handmade gold jewelry manufacturing workshops in Bangladesh.

Traditionally, handmade gold jewelry played a very important role in the cultural heritage of Bangladesh. Goldsmiths still are partially using ancient manufacturing process with coal fire, candle flame blowing, and nitric and sulfuric acid treatments. Such process leads to the contamination of workplace with the dust of toxic metals, acidic vapors, and particles of different natures.

Sediment color tool for targeting arsenic-safe aquifers for the installation of shallow drinking water tubewells.

In rural Bangladesh, drinking water supply mostly comes from shallow hand tubewells installed manually by the local drillers, the main driving force in tubewell installation. This study was aimed at developing a sediment color tool on the basis of local driller's perception of sediment color, arsenic (As) concentration of tubewell waters and respective color of aquifer sediments. Laboratory analysis of 521 groundwater samples collected from 144 wells during 2009 to 2011 indicate that As concentrations in groundwater were generally higher in the black colored sediments with an average of 239 μg/L.

Seasonal variation of trihalomethane formation potential in treated water supplies of Delhi City (India).

The main goal in using chlorine as water disinfectant is to protect the water in the distribution systems against microbial contamination and to prevent and control re-growth of microorganisms in the water distribution system. Organics in water have the potential to generate harmful disinfection by-products (DBPs) such as trihalomethanes (THMs) as a result of their reaction with chlorine. DBPs are increasingly recognized as cancerous agents.

Seasonal and spatial variation of Yamuna River water quality in Delhi, India.

Yamuna river pollution has been extensively studied with regard to some selected parameters in five locations at Palla, Nizamuddin Midstream, Nizamuddin Quarter Stream, Agra Canal Midstream, and Agra Canal Quarter Stream in Delhi, India. Seasonal and location-wise variation of pollutants namely dissolve oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN), ammonia (AMM), total coliform and fecal coliform were studied for 6 years during the period of 2000-2005. The study results revealed the lowest level of pollution during monsoon.

Trihalomethane formation potential in treated water supplies in urban metro city.

Trihalomethane (THM) formation potential (TFP) is very useful test to assess the level of the formation of trihalomethanes in worst case scenario. Organics in water have the potential to generate harmful disinfection by-products (DBPs) such as THMs, as a result of their reaction with disinfectant chlorine used in drinking water. DBPs are increasingly recognized as cancerous agents.

Groundwater chemistry and arsenic mobilization in the Holocene flood plains in south-central Bangladesh.

A comparative study of arsenic enrichment in the Bengal Delta (BD) was carried out in three alluvial aquifers in south-central Bangladesh. Investigated sites included Sonargaon in Narayanganj, Chandina in Comilla and Sirajdikhan in Munshiganj districts. At all sites samples from different depths were collected, and water chemistry and redox status vs.

Geochemical characterisation of shallow aquifer sediments of Matlab Upazila, Southeastern Bangladesh - implications for targeting low-As aquifers.

High arsenic (As) concentrations in groundwater pose a serious threat to the health of millions of people in Bangladesh. Reductive dissolution of Fe(III)-oxyhydroxides and release of its adsorbed As is considered to be the principal mechanism responsible for mobilisation of As. The distribution of As is extremely heterogeneous both laterally and vertically.

Clinical and neurological study of women with precatamenial epilepsy.

Objective: To describe clinical features and seizure dispersion in precatamenial/pericatamenial epilepsy patients.

Design: Case series.

Place And Duration Of Study: Department of Neurology (formerly Neuropsychiatry), Jinnah Postgraduate Medical Centre (JPMC), Karachi, from July 1991 to November 2001.

Influence of steroid hormones in women with mild catamenial epilepsy.

Background: In view of considerable differences of opinion regarding the reproductive steroid hormonal pathogenesis in catamenial epilepsy, hormonal analysis of estrogen and progesterone in catamenial epileptics for a precise correlation is of significant importance.

Methods: Clinical, neurological and physiological assessments, and radioimmunoassay of plasma estradiol-17beta and progesterone a day prior to the onset of menstruation were carried out in noncatamenial and mild catamenial epileptics having multiple frequency tonic-clonic (primary and secondary generalized) seizures.

Results: Highly significant rise (p > 0.

Targeting low-arsenic aquifers in Matlab Upazila, Southeastern Bangladesh.

Groundwater with high concentration of geogenic arsenic (As) occurs extensively in the Holocene alluvial aquifers of Bangladesh. Local drillers in Matlab Upazilla are constructing deeper tubewells than in the recent past, primarily because of low concentrations of dissolved Fe and As. Locally a thick layer of black to grey sediments overlies an oxidised unit of yellowish-grey to reddish-brown sediments.
