Smog is a serious problem in many cities and continues to harm human health. [30] [31] Ground-level ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma. [14]
Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
Carbon monoxide also binds to the hemeprotein myoglobin. It has a high affinity for myoglobin, about 60 times greater than that of oxygen. [21] Carbon monoxide bound to myoglobin may impair its ability to utilize oxygen. [49] This causes reduced cardiac output and hypotension, which may result in brain ischemia. [21]
These life-saving devices are designed to alert you in case of fires or carbon monoxide poisoning when you are not around. They are easy to install and maintain. Take your time with safety. Double ...
Many homes around the world used solid fuels for cooking. These fuels release large amounts of carbon monoxide and fine particulate matter. [46] These chemical irritants when inhaled may cause different pulmonary conditions ranging from pulmonary epithelial cancer or acute pulmonary tract infection. [47]
The average fuel economy for new light-duty vehicles sold in the US of the 2017 model year was about 24.9 MPG giving around 0.36 kg (0.79 lb) of CO 2 per mile. [25] The Department of Transportation's MOBILE 6.2 model, used by regional governments to model air quality, uses a fleet average (all cars, old and new) of 20.3 mpg giving around 0.44 ...
Carbon monoxide detectors should be installed between knee to head height on every level of the home, especially those floors with fuel burning appliances and outside of sleeping areas.
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
