Abstract The groundwater quality of the Gopalganj district in Bangladesh was not well documented. Therefore, this research done to determine study area. water index and human health risk for heavy metal ingestion were used describe quality. performed through estimation turbidity, pH, electrical conductivity, total dissolved solids, concentration sodium, potassium, ammonium, nitrate, iron, manganese, zinc, copper, arsenic. mean solids two upazila within permissible limit. However,...
The study focuses on the chemistry of groundwater and if it is suitable for drinking use in agriculture using water quality indices, GIS mapping, multivariate analyses Sharsa Upazila, Jashore district, Bangladesh. In this study, concentration NH
Ziala Village of Satkhira District in Bangladesh is well known for cow dung management and biogas production. Biogas plants produce huge quantities organic residues biogas. Cow widely used the plant as a part waste The are fertilizer fuel Village. Therefore, study was conducted to observe effectiveness using produced its subsequent impacts on socio-economic profile. based face interview randomly selected dairy farmers 2014. Twelve representative samples were interviewing. Findings suggested...
The composition of groundwater governs the drinking and irrigation water suitability. A large part coastal region Bangladesh is affected responsible for changing groundwater. This research attempted to observe quality Bhola Sadar Char Fasson upazilas in Bangladesh. Twenty-eight (28) samples, 27 at depths 260–430 m (850–1400 ft) 1 from a crop field, were collected analyzed. samples was determined through evaluation odor, color, turbidity, electrical conductivity, pH, total dissolved solids,...
Monitoring of groundwater resources in coastal areas is vital for human needs, agriculture, ecosystems, securing water supply, biodiversity, and environmental sustainability. Although the utilization quality index (WQI) models has proven effective monitoring resources, it faced substantial criticism due to its inconsistent outcomes, prompting need more reliable assessment methods. Therefore, this study addresses concern by employing data-driven root mean squared (RMS) evaluate Bhola district...
During the tannery production process, huge quantities of waste especially chrome shaving are produced and being discharged directly into environment Bangladesh. To know concentration some heavy metals in shaving, samples were collected, digested, analyzed. Among determined e.g. zinc (Zn), lead (Pb), chromium (Cr), Cr was very high. The average 13,832.70 mg Kg−1 dry weight which equivalent to almost 1.383%. Chromium leather shavings poses a critical problem for disposal or management....
The groundwater (GW) of Bangladesh is predominantly contaminated with arsenic (As) and iron (Fe) which has a bad impact on human health. We tried to remove these elements easily available mahogany-fruit (Swietenia mahagoni) husk charcoal (MHC) banana (Musa acuminata) peduncle (BPC). trial was implemented 3 replications throughout the research. sampled GW contained 0.06 mg As L-1 4.83 Fe L-1. Firstly, pH 3, 5, 7, 9 250 dose. MHC removed almost 91.05% at 5.0, BPC 86.67% 9. However, in case Fe,...
Abstract This study aimed to determine the quality of drinking water supplied in different types food stalls Jashore Municipality, Bangladesh. A total 35 samples were collected from tea stalls, street side fast normal restaurants and well-furnished restaurants. The was evaluated by determining distinct physical, chemical biological parameters. results revealed that used for purpose desired terms turbidity, electrical conductivity, pH, dissolved solids, nitrate (NO 3 − ), sulfate (SO 4 2−...
Plastic wastes are growing fast and affecting the environment negatively. Thus, finding different methods of disposing is becoming a major concern. This research aimed to minimize plastic by recycling it into construction materials. For this, grinding high-density polyethylene (HDPE) was mixed with cement at percentages produce bricks. The compressive strengths, density, water absorption capacity were investigated. strength found within recommended value (2000 psi) up 35% mixture HDPE....
The hexavalent form of chromium [Cr (VI)] and divalent copper [Cu (II)] are the major pollutants found in discharge effluents tannery industries. Therefore, before discharging effluent to surrounding environment these elements need be removed. Usually, low-cost bio-adsorbent used clean up polluted effluent. Current research was conducted determine effectiveness two bio-adsorbents namely water-hyacinth (Eichhornia crassipes) shoot powder (WSP) arum (Colocasia sculenta) (ASP) removing from...

ABSTRACT This study explored the groundwater chemistry, suitability, and potential human health risks in Jhenaidah district, Bangladesh. A total of 54 samples were collected from area, a set multivariate approaches applied to achieve objectives. Study results show concentration HCO3−, Ca2+, As, Fe, Mn exceeded Bangladesh drinking quality guidelines 100, 98, 44, 28, 63% samples, respectively. The index shows only 15% are suitable for purposes, whereas various irrigation water indices like EC,...
This study evaluated heavy metal (HM) contamination in sediments from the Malbasag River Ormoc City Port, Leyte, Philippines. A total of thirty sediment samples were collected randomly ten locations along river using an Ekman grab sampler. Atomic absorption spectrophotometry revealed HM concentrations order Mn > Zn Cu Ni Pb Cd. All HMs exceeded quality guideline (SQG) thresholds except for Mn. Contamination was assessed indices such as factor (CF), pollution load index (PLI),...

Abstract A hydroponic experiment was conducted to observe the effect of arsenic (As) on a number physiological and mineralogical properties rice (Oryza sativa L. cv. Akihikari) seedlings. Seedlings were treated with 0, 6.7, 13.4 26.8 µmol L−1 As (0, 0.5, 1.0 2.0 mg L−1) for 14 days in greenhouse. Shoot dry matter yield decreased by 23, 56 64%; however, values roots 15, 35 42% treatments, respectively. height 11, 43%, while that 6, 11 33%, These results indicated shoot more sensitive than...
Salinity intrusion affects the soils and water for irrigation drinking purpose severely in coastal Khulna District. Therefore, current research was done to find out salinity gradients different sources of surface e.g.- river water, canal pond together with deep tube well Southern parts Previously, these were used purposes. Water samples collected from selected Unions Batiaghata, Dacope Koyra Upazila District, because Upzilas situated near Bay Bengal. A total 51water determine physical...
