carbon dioxide hydrates in water to become carbonic acid and is corrosive. In petroleum production, the velocity of the carbon dioxide gas can increase the corrosion rate to very high levels,with the presence of salts becoming unimportant. Carbon dioxide is used in preparing carbonated beverages, ...

Why is Carbon Monoxide Dangerous? When carbon monoxide is inhaled, it passes from the lungs into the hemoglobin moleculesof red blood cells. Carbon monoxide binds to hemoglobin at the same site as and preferentially to oxygen, forming carboxyhemoglobin. Carboxyhemoglobin interferes with the oxygen tr...
In room air the approximate half-life is as much as 200 minutes, and during hyperbaric oxygen therapy it is as short as 12–20 minutes. TOXIC DOSE The recommended workplace limit (ACGIH TLV-TWA) for carbon monoxide is 25 ppm as an 8-hour time-weighted average. The level considered ...
OXYGEN affinity of haemoglobin inside red blood cells is decreased to a level where oxygen unloading can proceed at sufficiently high partial pressures in the tissue capillaries. This adaptation of oxygen affinity is accomplished mainly by the interaction of haemoglobin with intraerythrocytic phosphates 1...
Large quantities of carbon dioxide have been used in times of high energy costs in conjunction with enhanced oil recovery (EOR). This practice of injecting the gas at high pressure into geological formations to increase oil and natural gas yield, although highly effective, also increases the conce...

The sprinters CO2 storage capacities were 2.69 and 2.14 ml kg-1 Torr-1 at low and high work rates, respectively. The corresponding mean values for the runners were 4.56 and 3.92 ml kg-1 Torr-1, respectively. These results may be explained by the metabolic differences between the sprinters...
