Background: This toxicological investigation involves a report on the death of four ‎occupants of a sport utility vehicle on one of the major busy Federal roads of Nigeria ‎where they were held for up to three hours in a traffic jam while the car was steaming.‎ Methods: Autopsy was executed using the standard procedure and toxicological ‎analysis was done using simple spectrophotometric method...

Ordered nanoporous silicas containing various binary copper-manganese oxides were prepared as catalytic systems for effective carbon monoxide elimination. The carbon monoxide elimination efficiency was demonstrated as a function of the [Mn]/[Cu] ratio and reaction time. The prepared catalysts were characterized by Brunauer-Emmett-Teller (BET) method, small- and wide-angle X-ray diffraction (XRD...

background diatomite coated by nanoparticles of copper and zinc mixed oxides were used to investigate catalytic oxidation of carbon monoxide. objectives aim of this paper was to investigatediatomite performance as a supporting host to confine the cuo and zno nanoparticles and its catalytic activity for carbon monoxide oxidation. materials and methods the prepared catalysts were characterized by...

Objective(s): Cardiotoxicity is one of the major consequences in carbon monoxide poisoning. Following our previous work, in this study we aimed to define the myocardium changes induced by carbon monoxide (CO) intoxication and evaluate erythropoietin (EPO) effect on CO cardiotoxicity in rat. Materials and Methods:  Severe carbon monoxide toxicity induced by 3000 ppm CO in Wistar rat.  EPO was ad...

Proton-decoupled natural abundance 13C NMR spectra of carbon monoxide hemoglobins were recorded at 15.18 MHz by the Fourier transform method, under conditions of spectrometer sensitivity sufficient for detection of individual carbon resonances. The aromatic region of each spectrum contains broad bands of methine carbon resonances, and some relatively narrow peaks arising from nonprotonated carb...

More than a million workers are at risk for methylene chloride exposure. Aerosol sprays and paint stripping may also cause significant nonoccupational exposures. After methylene chloride inhalation, significant amounts of carbon monoxide are formed in vivo as a metabolic by-product. Poisoning predominantly affects the central nervous system and results from both carboxyhemoglobin formation and ...

BACKGROUND AND OBJECTIVES Carbon monoxide is a toxic gas for humans and is still a silent killer in both developed and developing countries. The aim of this case series was to evaluate early radiological images as a predictor of subsequent neuropsychological sequelae, following carbon monoxide poisoning. CASE 1 After carbon monoxide exposure, early computed tomography scans and magnetic reson...

Biomass burning is a major source of emissions to the atmosphere. Some of these emissions may change global climate. This paper uses combustion eff iciency as an independent variable for predicting emission factors for, among others, carbon monoxide, carbon dioxide, methane, and particulate matter. Other gases are correlated with the release of carbon monoxide. The release of nitrogen and sulfu...

The reductive functionalization of carbon dioxide into high value organics was accomplished via the coupling with carbon monoxide and ethylene/propylene at a zerovalent nickel species bearing the 2-((di-t-butylphosphino)methyl)pyridine ligand (PN). An initial oxidative coupling between carbon dioxide, olefin, and (PN)Ni(1,5-cyclooctadiene) afforded five-membered nickelacycle lactone species, wh...
