The effects of elevated pressures (25, 50, 75, and 100 psig) on the toxicity of carbon monoxide (CO) in guinea pigs, rats, and mice were examined in a series of 4-hr exposures. The partial pressure of oxygen (pO 2) was maintained between 140 and 160 mm Hg during all exposures. ...
The Wayne County Medical Examiner's Office released the official cause of death of two children who died while sleeping in a van with family in Detroit. Officials said 2-year-old A'Millah Currie and 9-year-old Darnell Currie Jr. died from carbon monoxide toxicity...
The etiology of carbon monoxide is due to its effect on oxygen binding to the hemoglobin molecule. Carbon monoxide binds to hemoglobin, forming carboxyhemoglobin (COHb) with a 220 times greater affinity to hemoglobin than oxygen. This reduces the oxygen-carrying capacity of hemoglobin and leads to...

Carbon nanomaterials are a growing family of materials featuring unique physicochemical properties, and their widespread application is accompanied by increasing human exposure. Considerable efforts have been made to characterize the potential toxicity o
Carbon monoxide (CO) intoxication is one of the most frequent causes of accidental poisoning, mechanistically related to the inhibition of oxygen transport following blockage of the oxygen binding site of hemoglobin. However, it has become evident that CO is also a gaseous signaling molecule like ni...
First, the carbon monoxide elimination process exhibits biphasic decreases of COHb concentration compatible with a two-compartment model: an initial rapid decrease (distribution phase), followed by a slower phase (elimination phase). In other words, COHb elimination should be described by the sum of...
