Assessment of Heavy Metal Contamination and Health Risk Associated with Cultivated Vegetables along Dhaka-Mymensingh Highway, Bangladesh.

The purpose of this research work is to evaluate the degree of eight heavy metals (Fe, Mn, Cu, Zn, Cd, Pb, Cr, and Ni) contamination and health risks of three regularly consumed vegetables (papaya, bottle gourd, and esculent) near one of Bangladesh's busiest roadways, the Dhaka-Mymensingh highway. The heavy metal concentrations in 45 vegetable samples were analyzed using an atomic absorption spectrometer (AAS). These samples were collected from five different sampling sites based on various land use patterns adjacent to the highway.

Identification and evaluation of antimicrobial and anti-arthritis activities of hydroethanolic extract of Rubus ellipticus leaves.

is a native plant to India's tropical and subtropical regions and has been used as a traditional medicinal. The aim of study was to identify and evaluate the antimicrobial and anti-arthritis activities of hydroethanolic extract of leaves (HEERE). The leaves were collected from the Narkanda Valley, India and were shade-dried and finely ground to produce the powder.

Encapsulation of halocadmate anion via hydrogen bonding: synthesis and characterization of bis(diethylenetriamine)cobalt(III) complex containing hexabromocadmate anion.

In this work, the encapsulation of [CdBr] by six cations, [Co(dien)] has been described with the help of single crystal X-ray structural study in the complex, -[Co(dien)][CdBr]Br. The complex anion, [CdBr] has been obtained through solution method while attempting to synthesize complex dianion, [CdBr]. This newly synthesized complex has been initially characterized by elemental analyses and spectroscopic studies (IR, NMR and UV-Visible).

Binding of permanganate anion to pentaammineazidocobalt(III) cation in solution and solid phases: synthesis, characterization, X-ray structure, and genotoxic effects of [Co(NH)N](MnO)⋅HO.

A pentaammineazidocobalt(III) complex, [Co(NH)N](MnO)XHO has been synthesized by an one-pot synthesis method. It was characterized by studies such as infrared (IR) and UV-visible spectroscopy. The single crystal X-ray structure analysis revealed that the title complex crystallizes in space group Cc.

Green Synthesis, Characterization and Antimicrobial Activities of Copper Nanoparticles from the Rhizomes Extract of .

Background: Green synthesized nanoparticles from the solvent extract of various plant parts show better biological activities as compared to parent solvent plant extract. Traditionally rhizomes of Picrorhiza kurroa are used to cure various diseases like diarrhea, fever, jaundice, eye infection, skin problems, asthma, arthritis, cancer, diabetes, gastrointestinal problems.

Objective: The present study describes the synthesis of copper nanoparticles from a hydroethanolic extract of P.

Sonochemical synthesis, characterization, thermal and semiconducting behavior of nano-sized azidopentaamminecobalt(III) complexes containing anion, CrO or CrO.

New nano-sized cobalt(III) coordination complexes, [Co(NH)N]CrO (1N) and [Co(NH)N]CrO (2N) were synthesized using an innovative sonochemical methodology based on reaction between [Co(NH)N]Cl and potassium salt of CrO or CrO in aqueous medium. These complexes were also compared with their respective bulks which were synthesized under identical conditions in the absence of sonicaion. All the complexes were characterized by elemental analysis and spectroscopic techniques (UV-visible and IR).

Sonochemical synthesis, characterization, antimicrobial activity and textile dyeing behavior of nano-sized cobalt(III) complexes.

Using ultrasonic irradiations, nano-sized cobalt(III) coordination complexes, [Co(NH)]Cl·2HO (A), [Co(en)]Cl·3HO (B) (en-ethylenediamine) and [Co(dien)]Cl·3.5HO (C) (dien-diethylenetriamine) were synthesized. These complexes were characterized by spectroscopic studies like IR, UV/Visible and NMR.

Effect of combustion variables on PAHs emission from incineration of cellulose waste filters from acrylic industry.

Incineration of cellulose waste filter from acrylic industry showed the presence of 13-16 polycyclic aromatic hydrocarbons (PAHs) from the list of 16 priority pollutants with an airflow rate of 1, 2, 3, and 4 L min(-1) in laboratory scale quartz tube vertical incinerator at 700-1,000 degrees C at an interval of 100 degrees C. The amount of total 16 PAHs increases with the increase in temperature with airflow rate of 1 L min(-1) and was found to be 9.4 times at 1,000 degrees C than at 700 degrees C.

Toxic environmental releases from medical waste incineration: a review.

Toxic releases from medical waste incineration comprising organic emissions such as polychlorinated dibenzo-dioxin/furan (PCDD/Fs) and polycyclic aromatic hydrocarbons (PAHs), inorganic emissions and ashes containing toxic metals have been reviewed. Attempts made by various investigators to reduce/eliminate emissions have also been included. Legislations concerning emission standards for medical waste incinerators have been discussed.

The effect of temperature on PAHs emission from incineration of acrylic waste.

Incineration of acrylic waste solution in a lab scale quartz tube vertical incinerator showed the presence of 12-15 polycyclic aromatic hydrocarbons (PAHs) from a list of 16 priority pollutants at 700-1100 degrees C after an interval of 50 degrees C. The amount of total 16 PAHs at 900 and 1100 degrees C was about 8.5 and 1.
