Carbon monoxide levels in the breath of smokers and nonsmokers: effect of domestic heating systems. J Epidemiol Community Health. 1985 Mar; 39 (1):75–78.Cox BD,.Whichelow MJ. Carbon monoxide levels in the breath of smokers and nonsmokers: effect of domestic heating systems. J.Epidemiol....
Carbon monoxideis produced during theincomplete combustionof carbon-containing fuels, such as natural gas, kerosene, and wood. Its production rate by gas ranges is actually greater than that fornitrogen dioxide, and indoor levels can be several times greater than those found outdoors. Concentrations ...
? Carbon monoxide (CAS NO.630-08-0), its Synonyms are Carbon oxide (CO) ; Carbone (oxyde de) ; Carbonic oxide ; Carbonio (ossido di) ; Kohlenmonoxid ; Kohlenoxyd ; Oxyde de carbone . It is a colorless cryogenic liquid. 4.15 Toxicity LC50 inhal (rat) 1807 ppm (2065 mg/m3; 4 ...
There were related studies about carbon monoxide (CO) exposure on commuter and driver in the past. Flachsbart et al. (1987) stated that traffic density, vehicle mix, roadway settings, meteorology, ambient CO level and period of the day are the important factors influencing in-vehicle CO level...
INTRODUCTION: Carbon monoxide (CO) is a toxic gas with potential for detriment to spaceflight operations. An analytical model was developed to investigate if a maximum CO contamination of 1 ppm in the oxygen (O2) supply reached dangerous levels during extravehicular activity (EVA). Occupational mon...
Two designs were evaluated: a processor optimized to improve the thermal efficiency of the methanol reforming reactor from 9 to above 20%, and a system tailored to decrease the carbon monoxide levels to below 500 ppm, preferably lower than 100 ppm. Each design was operated over a range of ...
Carbon Oxide refers to a group of compounds that include carbon monoxide (CO) and carbon dioxide (CO2). Carbon monoxide is harmful when exposed above 25 ppm, while carbon dioxide is less toxic. Tin dioxide nanowires have been used to sense carbon monoxide in the presence of reducing gases li...
Carbon Monoxide--CO Proper Shipping Name: Carbon Monoxide, Compressed UN NO.: UN 1016 Hazard labels: 2.3-Toxic Gas--Flammable gas We deliver CO in high-pressure steel and aluminum cylinders that range from 25 to 10,000 liters with pressures up to 200 bar Product Parameters...
Carbon monoxide (CO) levels were measured in the cabs of 17 aircraft fuelling vehicles on which the exhaust system was vented under the front bumper to minimise contact between the hot exhaust gases and the jet fuel. The cabs were examined with windows closed and heaters on in different posit...
