Abstract Microplastics (MPs) have become an emerging global pollutant due to their widespread dispersion and potential threats marine ecosystems. However, studies on MPs in estuarine coastal ecosystems of Bangladesh are very limited. Here, we conducted the first study abundance, distribution, characteristics, risk assessment microplastics sediment Karnaphuli River estuary, Bangladesh. Microplastic particles were extracted from sediments 30 stations along estuary by density separation then...
This research work was focused to evaluate the concentration of heavy metals (i.e., Cr, Pb, Mn, Cu and Fe) in sediment samples collected from Dhaleshwari River near area a newly established tannery industrial estate, Savar, Bangladesh. The were ascertained by atomic absorption spectrophotometer (AAS). study revealed that metal for chromium (Cr), lead (Pb), manganese (Mn), copper (Cu) iron (Fe) found be 14.8–748 (186 ± 241) mg/kg, 2.38–21.1 (8.78 6.15) 1.59–6.29 (3.12 1.38) 0.36–4.75 (1.76...
Accumulation of metals (Cr, Zn, Ni, Cd, and Cu) in leafy vegetables cultivated on tannery effluent contaminated soil agricultural land were determined with an Atomic Absorption Spectrophotometer (AAS). The values risk factors for the human population studied, where transferred from to plants via finally, transmitted body through consumption these metal accumulated vegetables. Leafy vegetables, namely Stem amaranths (Amaranthus lividus), Spinach (Spinacia oleracea), Red gangeticus), Jute...
This study demonstrates the level of heavy metal pollution in Halda River, only natural breeding source carps Bangladesh. Water was collected from 12 different sampling points along River. at various locations found satisfactory terms assessed physicochemical parameters (pH, electrical conductivity, and total dissolved solids). The presence cations anions also studied using ion chromatography. Atomic absorption spectroscopy used to identify quantify metals water samples. Among metals, Cd,...
A significant progress has been made to increase electricity generation capacity in the country over last decade. The supply for growing demand is foremost challenge of government, as move towards vision middle-income status by 2021 and high-income 2041. energy security concern due running out gas soon. Despite on recent years, goal access all would not be attainable without implementation a consistent national policy. Well-coordinated policy required achieve sustainable development goals...
Kuakata beach, known as Daughter of Sea in Bangladesh, has drawn a growing number tourists from all over the world, leading to higher use single plastic products. This study was first attempt describe occurrence, spatial distribution, and ecological risk microplastics (MPs) beach sediments. A total 24 surface sediment samples were collected intertidal zone MPs extracted using density separation method stereomicroscope. Fourier transform infrared (FTIR) spectroscopy used for qualitative...
Shrimp is one of the major export products in South Asian countries and also an eminent source nutrition for humans. Hence, any negative effect this industry may affect not only country’s economy but human health. Therefore, study, we aimed to assess heavy metal contamination associated health risks cultured shrimp (Penaeus monodon) aquaculture sludge collected from three farms Cox’s Bazar district, Bangladesh. The results showed that among eight metals studied, Pb (17.75 ± 1.5 mg/kg) Cu...
This groundbreaking study conducted a meticulous examination of heavy metal concentrations, including Pb, Cd, Cr, Cu, Co, Ni, Zn, and As, in water samples from five distinct coastal areas Bangladesh. Employing advanced techniques such as flame atomic absorption spectrometry (FAAS) hydride generation AAS, the researchers provided detailed analysis distribution pollution levels. The quantification results illuminated Pb with highest average concentration, followed by As samples. Halda River...
Environmental sustainability has gained acceptance to achieving the goal of a secure ecosystem with reliable management system. Heavy metal remediation aqueous streams is special concern due intractability and persistence in environment. Adsorption potential alternative existing inefficient conventional technologies for removal recovery ions from solutions becomes vital align Sustainable Development Goals (SDGs) mitigate adverse environmental social impacts. Calcium Alginate-Graphene oxide...
In recent decades, water quality is a great concern for the human being as it most important natural resource but polluted by increasing population activities. this study, surface samples were collected in wet and dry season from Halda River, Bangladesh, 12 physicochemical properties 10 traces elements (Cd, Cr, Mn, Fe, Co, Cu, Zn, As, Pb, Hg) analyzed to assess metal toxicity, identify possible sources, determine carcinogenic noncarcinogenic risk adults child residents. During season, mean...
Globally, both natural water bodies and aquaculture systems are being severely contaminated by heavy metals due to rising anthropogenic activities. Fish living in aquatic environments can easily accumulate their bodies, which then be transferred consumers put them at risk. In this study, metal concentrations (Pb, Cd, Cr, As, Mn, Cu, Zn) different organs (gill, liver, muscle) of farmed wild Barramundi (Lates calcarifer) fish from the northern Bay Bengal were evaluated quantify compare...
Arbuscular mycorrhizal fungi (AMF) are symbiotically associated with crops. They increase biomass production, nutritional elements, and antioxidant activities in food vegetable crops grown soil under stress conditions. The present study focused on the effects of AMF (Acaulospora morrowiae, Paraglomus occultum, Funneliformis mosseae, Rhizophagus clarus, intraradices) growth yield, contents chlorophyll carotenoids, catalase (CAT) ascorbate peroxidase (APX), hydrogen peroxide (H2O2),...
In the recent years, air pollution has become an alarming issue for human health in many rapidly growing megacities including Dhaka and Narayanganj. Herein, status risk have been assessed by road dusts collected from landfills Narayanganj through determination of heavy metals Pb, Cd, Cr, As, Cu, Ni, Zn Mn using atomic absorption spectroscopy. The dust samples grouped into three sizes, example, <300−>150, <150−>75 < 75 μm, to assess degree metal accumulation particles. particles were...
