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...
Accumulation of microplastic in the marine environment is great concern and has been considered to be a growing problem coastal sediments Bangladesh. This research represents large-scale abundance, characterization contamination, its type polymer beach sediment Cox’s Bazar. To understand potential impacts associated with pollution Bazar area, quantification, identification, spatial distribution types were done from collected samples regions. All analyzed through visual Scanning Electron...
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...
Despite the high potential for microplastics (MPs) pollution in Bangladesh, presence of MPs industrial region has largely been unexplored Bangladesh. So, this study was conducted to determine whether MP is prevalent soil Bangladesh and extent its toxicity. To examine MPs, a total 12 samples were collected from Narayanganj, stereoscopic microscope used visually identify MPs. Prior that technique density separation sieving applied extract those samples. Among twelve investigated samples, 151...
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,...
Pollution generated by microplastics (MPs) has become an issue of global concern because to its severe effects on the general health ecosystem, especially terrestrial environment. There is a scarcity data based MP contamination research in Bangladesh that currently available, and no work previously been done industrial region Bangladesh. As result, this was undertaken with aim determining whether or not present area Barapukuria The method sieving density separation used process extracting...
Coal mining areas in Bangladesh are exposing to extreme environmental problems due the mobilization of heavy metals surrounding region. To assess persisting risk, several soil samples were collected from nearby coal mine areas. The amount pollution metal has been calculated determine extent contamination. Soil contamination assessment was carried out using evaluation indices such as index (HPI), degree (Cd), and factor (CF). concentration S, As, Ba and, F exceeded maximum level some samples....
Despite the high potential for microplastics (MPs) pollution in Bangladesh, no study on MP has been conducted any industrial area of Bangladesh. So, this was to determine whether is prevalent sector Bangladesh and extent its toxicity. To examine MPs, a total 12 soil samples were collected from region Narayanganj, stereoscopic microscope used visually identify MPs. Prior that technique density separation sieving applied extract MPs those samples. Among twelve investigated samples, 151 (Mean:...
After the COVID-19 pandemic, worldwide reliance and shift towards video communication platforms have highlighted importance of virtual learning. One major challenge in this aspect is determining actual engagement students during sessions. To address challenge, we present a research study that focuses on developing system will help evaluate participant's attentiveness one-on-one online We propose utilize screen sharing detection, face recognition, head pose estimation, eye gaze estimation to...
