When developing the AQHI, Health Canada's original analysis of health effects included five major air pollutants: particulates, ozone, and nitrogen dioxide (NO 2), as well as sulfur dioxide (SO 2), and carbon monoxide (CO). The latter two pollutants provided little information in predicting health effects and were removed from the AQHI formulation.
While the effects of air pollution on the respiratory diseases are well understood, air pollution also affects the cardiovascular system at the same level as or higher level than the respiratory system, [34] and the adverse cardiovascular health outcomes in both children and adults are high when exposed to air pollution. Carbon monoxide, oxides ...
Carbon monoxide (CO): The EPA set the first NAAQS for carbon monoxide in 1971. The primary standard was set at 9 ppm averaged over an 8-hour period and 35 ppm over a 1-hour period. [ 10 ] The majority of CO emitted into the ambient air is from mobile sources.
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 ...
A fan draws in polluted air and layers of filters capture and remove airborne pollutants, before expelling cleaner air. Most purifiers capture particles like dust and pollen, but the best air ...
Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. [23] Carbon monoxide is colorless, odorless and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin , which blocks the transport of oxygen.
