Explanation: Carbon monoxide, a poisonous gas, is commonly detected in the blood of drowning victims. This is because when a person is trapped in an enclosed space, such as a car or a room, with inadequate ventilation and is unable to escape, it can lead to carbon monoxide poisoning and subsequent drowning. Carbon monoxide can bind to hemoglobin in the blood, reducing its oxygen-carrying capacity and leading to asphyxia, which can be a contributing factor in drowning cases.
