why do carbon monoxide released from vehicles does not cause death?
Answers
Answer:
Carbon monoxide (CO) is a toxic air pollutant produced largely from vehicle emissions. Breathing CO at high concentrations leads to reduced oxygen transport by hemoglobin, which has health effects that include impaired reaction timing, headaches, lightheadedness, nausea, vomiting, weakness, clouding of consciousness, coma, and, at high enough concentrations and long enough exposure, death. In recognition of those health effects, the U.S. Environmental Protection Agency (EPA), as directed by the Clean Air Act, established the health-based National Ambient Air Quality Standards (NAAQS) for CO in 1971.
Most areas that were previously designated as "nonattainment" areas have come into compliance with the NAAQS for CO, but some locations still have difficulty in attaining the CO standards. Those locations tend to have topographical or meteorological characteristics that exacerbate pollution. In view of the challenges posed for some areas to attain compliance with the NAAQS for CO, congress asked the National Research Council to investigate the problem of CO in areas with meteorological and topographical problems. This interim report deals specifically with Fairbanks, Alaska. Fairbanks was chosen as a case study because its meteorological and topographical characteristics make it susceptible to severe winter inversions that trap CO and other pollutants
Answer:
In a typical year, nearly 400 Americans die from carbon monoxide poisoning, usually in their own home or car. Many of those deaths happen during the winter months, when people are heating their homes and reducing the amount of outside ventilation.
Explanation:
Carbon monoxide is produced by devices that burn fuels.
Unlike natural gas or LP gas, which have a characteristic odor added to them to alert you, carbon monoxide has no fumes and no color.
Most people with a mild exposure to carbon monoxide experience headaches, fatigue, and nausea. Unfortunately, the symptoms are easily overlooked because they are often flu-like.
Always back your car out of the garage to let it warm up. Never leave it running in the confined space of a garage, particularly if the garage is attached to the home.
Never dismiss a fender bender as something you’ll get checked later. Even minor collisions can cause breaks in your car’s exhaust system, allowing CO to enter into your passenger area
Never use a cooking device—an oven, grill, or camp stove—to heat your home.
The treatment for carbon monoxide poisoning is high-dose oxygen. Using higher atmospheric pressure around the body can speed up the effectiveness of the high-dose oxygen treatment.
