Thesis Title: Association Between Somatotypes, Blood Pressure and Lipid Profile of Selected Healthy Adults in Noakhali, Bangladesh.
Overview: Enter Project/Thesis OverviewHypertension is a leading global health concern and a major risk factor for cardiovascular disease, especially in low- and middle-income countries. While several anthropometric indices have been studied in relation to blood pressure (BP), limited research exists on the role of somatotypes-endomorphy (fatness), mesomorphy (muscularity), and ectomorphy (linearity)- as predictive indicators of BP in South Asian populations.In males, endomorphy and mesomorphy showed significant positive correlations with systolic and diastolic BP (p < 0.01), while ectomorphy was negatively associated (p < 0.01). In females, mesomorphy was positively associated with BP (p < 0.05), whereas endomorphy had a negative association (p = 0.029), and ectomorphy was not statistically significant. Smoking and high salt intake were independently associated with elevated BP in males (p < 0.01), while triglyceride levels showed a significant positive association with BP in females (p = 0.006). Somatotype components are significantly associated with blood pressure, with distinct gender-specific patterns. These findings suggest that somatotyping may serve as a useful, low-cost anthropometric tool for identifying individuals at risk for hypertension, particularly in resource-constrained settings. Public health strategies should consider integrating somatotype assessment alongside lifestyle and biochemical factors to enhance hypertension screening and prevention efforts.
Thesis Title: Relation of heavy metals concentration in poultry and poultry feeds collected from integrated farm in Noakhali district of Bangladesh: A chain of transformation and associated human health risk assessments.
Overview: Enter Project/Thesis This study investigates the concentrations of heavy metals and macro-elements in poultry species (duck, domestic hen, Sonali cock, broiler, layer), eggs, droppings, and feed collected from integrated farms in the Noakhali district of Bangladesh and assesses the associated human health risks. A total of 101 samples—including muscle, liver, bone, brain, skin, eggs, droppings, and three types of poultry feed—were analyzed using Atomic Absorption Spectroscopy (AAS) to detect metals like lead (Pb), cadmium (Cd), arsenic (As), copper (Cu), nickel (Ni), manganese (Mn), and iron (Fe), as well as macro-elements such as calcium (Ca), sodium (Na), and phosphorus (P). The results showed elevated levels of toxic metals, especially Pb, As, Cu, and Fe; far exceeding safe limits. The findings revealed that several poultry parts, particularly liver, bone and brain tissues, contained heavy metal concentrations exceeding maximum permissible limits (MPLs) set by FAO/WHO, indicating potential health hazards. Highest metal accumulation in poultry parts was for Fe (185.54 mg/kg) followed by Cu (17 mg/kg) and Mn (8.20 mg/kg). Egg samples, particularly from layer hens, exhibited alarming levels of Pb (up to 1.967 mg/kg) and Cu (up to 59.004 mg/kg). Poultry feed was contaminated beyond FAO/WHO permissible limits, especially for Pb (5.348 mg/kg) and As (4.348 mg/kg). Droppings, often used as fertilizer, contained substantial levels of Fe (237.72 mg/kg), Mn (15.13 mg/kg), and Cu (9.378 mg/kg), posing environmental risks. Descending order of heavy metals (Mean Concentrations mg/kg): Poultry Parts: Fe > Cu > Mn > Pb > As > Ni > Cd; Eggs: Fe > Cu > Mn > Pb > As > Ni > Cd, Feed: Fe > Mn > Cu > Pb > As > Ni > Cd, Droppings: Fe > Mn > Cu > Pb > Ni > Cd > As. The bioaccumulation factor (BAF) was highest for Fe and Cu, indicating significant transfer from feed to poultry tissues. Health risk assessments, including Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), Hazard Index (HI), and Target Cancer Risk (TCR), were conducted using USEPA guidelines. Several TTHQ and HI values exceeded the safety threshold of 1, indicating potential non-carcinogenic risks. Carcinogenic risk values (TCR) for As, Cd, and Pb also approached or exceeded acceptable limits (10−6 to 10−4). Cluster analysis (CA) and principal component analysis (PCA) revealed grouping of metals based on likely environmental or dietary origins. This research highlights the urgent need for regulatory oversight, improved farming practices, and continuous monitoring to ensure food safety and safeguard public health.
Thesis Title: Assessment of Physico-Chemical and Microbiological Quality of Drinking Water in Differet Upazilas of Noakhali District in Bangladesh
Overview: Enter Project/Thesis OverviewThe name of water is called life. Providing safe drinking water is one of the momentous public health precedencies and the drinking water quality is closely associated with human health. The most important human well-being is af fordable, abundant, and clean drinking water. This study has been conducted for assessing the drinking water quality of various locations in Noakhali. To tal of nine water samples have been collected from three different locations (Sadar, Begumgonj, and Hatiya). Each sampling location consists of three separate sampling points. The samples have been analysed for their physi cal-chemical and microbiological quality in order to observe health impact. Physicochemical parameters of the collected samples like Temperature, pH, Electric Conductivity (EC), Total dissolved solid (TDS), and Salinity have measured by Multiparameter meter and Microbial parameters like Total Via ble Bacterial Count (TVBC), Total Coliform (TC) and the presence of E. coli have also examined. All the parameters have analysed and compared with WHO drinking water quality standards to understand the overall water quality status of the study area. The study has shown that the water samples in almost all the locations have been contaminated by microbial contamination and the range of the physicochemical parameters was not suitable for consumption. Preliminary treatment is needed prior to using the water for drinking purposes and necessary steps should be taken for alternative safe sources of drinking water.
Thesis Title: Assessment of Physico-Chemical and Microbiological Quality of Drinking Water in Three Upazilas of Noakhali District in Bangladesh
Overview: Enter Project/Thesis OThis study was driven for analyzing the drinking water quality of three upa zillas at Noakhali district in Bangladesh. Nine different areas drinking water samples were collected from three upazilas (sadar-upazila, kabirhat upazila, Chatkhil upazila). Physical & chemical parameters of the collected samples like pH, electrical conductivity, salt, TDS, chloride-ion, iron content were measured and microbial parameters like Total Viable Bacterial Count (TVBC), Most Probable Number (MPN) of coliforms, E. coli, Pseudomonas, Klebsiella, Enterobacter aerogenes were also detected. All the parameters were compared with WHO drinking water quality standard ranges to under stand the condition of drinking water in these areas. This study showed the pH of Chatkhil upazila was comparatively lower (6.18) than other upazilas. Electrical conductivity was also lower (252.1 µS/cm) in Chatkhil than other upazilas. Salt volume was comparatively higher (554.33 ppm) in sadar upazila sample than in others. TDS of all upazila samples were in an acceptable range. Chloride-ion was very much higher (7326.33 mg/L) in upazila-sadar. Iron content was mostly (3 mg/L) in Chatkhil upazila. Total bacterial load was comparatively higher (7.13 × 106 CFU/mL) in Kabirhat upazila. Most Proba ble Number (MPN) of Coliforms were comparatively higher (24.67 number of coliforms/100mL) in upazila-sadar than others. This study also showed the water samples that were collected almost all were contaminated by E. coli bacteria without supply water in upazila-sadar. As a result, water was not suitable for drinking. Water purification is very urgently needed for saving people from water-borne diseases. So necessary steps should immediately be taken for purifying the sources of drinking water.
