Carbon monoxide is the most abundant of the criteria pollutants. High concentration of Carbon monoxide generally occurs in areas with heavy traffic congestion. There are adverse effects on Human health due to the high concentration of CO in the atmosphere. The metropolitan cities are facing such type of problems a lot. In a given signal (data of average CO per day, observed by DPCC Anand Vihar,...

Two rare copper complexes, a tri-alkene adduct [Cu(ttt-cdt)(FSbF(5))] and a non-classical carbon monoxide complex [Cu(ttt-cdt)(CO)][SbF(6)] with a high CO stretching frequency ([small nu, Greek, macron](CO) = 2160 cm(-1)), have been isolated using trans,trans,trans-1,5,9-cyclododecatriene (ttt-cdt) ligand.

A survey based citizen Science research of Carbon monoxide levels was conducted in Navi Mumbai, particularly at various Toll Plazas and Traffic signals. Carbon Monooxide levels were assessed in roadside built houses. Carbon monoxide is a product of incomplete combustion of organic matter due to insufficient oxygen supply to enable complete oxidation to carbon dioxide (CO2). It was found out tha...

OBJECTIVES This study was designed to compare the effects of inhaled carbon monoxide (CO), administered to achieve concentrations similar to those found in cigarette smoking, with the effects of cigarette smoking and air inhalation on heart rate and blood pressure, catecholamine release, platelet activation and C-reactive protein (CRP), a marker of inflammation. BACKGROUND Carbon monoxide may...

Adsorption and coadsorption of carbon monoxide and oxygen on different types of Au clusters on R(15 × 3)C/W(110) and R(15 × 12)C/W(110), respectively, are studied with respect to the catalytic behavior for oxidation of CO as well as of surface carbon. Carburization of the W(110) surface results in a weakening of the adsorption bond for molecularly adsorbed CO. Dissociation of carbon monoxide, w...

Carbon monoxide (CO) poisoning is common in modern society, resulting in significant morbidity and mortality in the United States annually. Over the past two decades, sufficient information has been published about carbon monoxide poisoning in the medical literature to draw firm conclusions about many aspects of the pathophysiology, diagnosis, and clinical management of the syndrome, along with...

Carbon monoxide is widely distributed in the environment, and acute or chronic toxic effects may be of considerable public health significance. A review of the basis for current ambient standards is given. Mortality and morbidity studies have been negative or equivocal in relating carbon monoxide levels to health effects, but studies in human subjects with compromised coronary or peripheral cir...

This review discusses the overlooked problem of carbon monoxide (CO) poisoning within small tents. It summarizes previous case reports, reviews the toxicity of CO, and attempts to draw conclusions from experimental work. Finally, practical recommendations are developed on avoiding CO poisoning within tents. The term carbon monoxide was used in a search of the Medline database covering the years...

Background: Poisoning with carbon monoxide occurs occasionally worldwide, and the gold diagnostic standard is to measure carboxyhemoglobin level in the blood. This study investigated the correlation between carboxyhemoglobin and the end-tidal carbon dioxide levels in 50 patients with carbon monoxide poisoning. Methods: We recruited 50 volunteer patients who had been admitted to the Emergency S...
