The present study was carried out to determine the level of bioaccumulation some heavy metals in a freshwater fish Ayre (Sperata aor Hamilton, 1822) collected from Rajfulbaria (23°48?56.36? N and 90°14?54.04? E) Dhaleshwari river. Four metals, namely chromium (Cr), copper (Cu), lead (Pb), cadmium (Cd) were selected for this study. Metal concentrations determined by Flame Atomic Absorption Spectrophotometer after nitric acid digestion samples. accumulated also compared with sediments waters...
Rooftop cultivation of vegetables is considered as a potential food source for urban population. However, rooftop products in the area can be contaminated by different types pollutants like toxic metals and polycyclic aromatic hydrocarbons (PAHs). The present study first that investigated concentrations PAHs soils grown peri-urban areas Bangladesh. Red amaranth Spinach were selected cultivation, both soil vegetable samples collected analyzed determining cadmium (Cd), copper (Cu), lead (Pb),...
Persuaded by the necessity of finding new sources antibiotics, Ag NPs were synthesized adopting a newly developed green synthesis technique and subsequently, their antibacterial activity against different pathogenic bacteria was evaluated.
The enormous numbers of applications TiO2 nanoparticles (NPs) cause concern about their risk to the environment and human health. Consequently, motivated by necessity searching for new sources NPs low cytotoxicity with antibacterial activity, we synthesized a green route using solution titanium(iv) isopropoxide as precursor an aqueous extract Artocarpus heterophyllus leaf reducing surface modifying agent. We investigated structure, shape, size, magnetic properties, evaluated antibiotic...
Abstract Spinel magnetite (Fe 3 O 4 ) nanoparticles (MNPs) were successfully synthesized from the reduction of stoichiometric ratio aqueous solutions Fe 2+ and 3+ with NaOH solution. Then naturally available Ipomoea aquatica leaf extract ( IA extract) was used for surface modification MNPs where biomolecules acted as stabilizer. Gas chromatography‐mass spectrometry (GC‐MS), Fourier transform infrared (FT‐IR), energy dispersive X‐ray (EDX) analyses evidence proper incorporation in MNPs....
This study investigated the human health risk assessment of polycyclic aromatic hydrocarbons (PAHs) (naphthalene, fluorene, phenanthrene, anthracene, pyrene, benzo(a)anthracene, chrycene, and benzo(a)pyrene) from consumption smoked fish (Coral, Telapia, Shrimp, Rupchanda) meat (Beef Shikh Kabab, Mutton Kashmiri Chicken Grill) highly consumed by Bangladeshi people quantified gas chromatography-mass spectrometry (GC-MS) technique. The samples were hydrolyzed in methanolic potassium hydroxide...
Background: Syzygium cumini is one of the evidence-based traditional medicinal plant used in treatment various ailments. Objectives: Herein, antioxidant property and anticancer against Ehrlich Ascites Carcinoma (EAC) cells were examined to find effective chemotherapeutics. Methods: In vitro assays, phytochemical chromatographic analyses determine properties chemical constituents cummini Bark Methanolic Extract (SCBME). Functional assays measure activity SCBME. Fluorescence microscopy RT-PCR...
In the search for a diluted magnetic semiconductor (DMS) spintronics devices, Zn1-xCoxO (x = 0, 0.0203, 0.0353, 0.0503, and 0.0652) nanomaterials (NMs) were synthesized using simple cost-effective co-precipitation technique. To demonstrate advantages of Co-doping, morphological, microstructure, optical, properties Co-doped ZnO NMs extensively investigated XRD, TEM, EDX, SAED, Raman spectroscopy, UV-visible vibrating sample magnetometer (VSM). The exhibited hexagonal wurtzite structure. Their...
