  2. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    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 ...

    en.wikipedia.org/wiki/Air_pollution

    Other examples include carbon monoxide gas from motor vehicle exhausts or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. Ground level ozone is a prominent example of a secondary pollutant. Some pollutants may be both primary and ...

    Health effects of transport include noise pollution and carbon monoxide emissions. While electric cars are being built to cut down CO 2 emission at the point of use, an approach that is becoming popular among cities worldwide is to prioritize public transport, bicycles, and pedestrian movement.

    What are the symptoms of carbon monoxide poisoning? In high concentrations, it can be deadly. The acute effects arise from carboxyhemoglobin formation in the blood, which hampers oxygen absorption.

    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.

  7. Carbon monoxide poisoning - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide_poisoning

    The harmful effects of carbon monoxide are generally considered to be due to tightly binding with the prosthetic heme moiety of hemoproteins that results in interference with cellular operations, for example: carbon monoxide binds with hemoglobin to form carboxyhemoglobin which affects gas exchange and cellular respiration.

    The effects of these laws have been very positive. Between 1970 and 2006, U.S. citizens enjoyed the following reductions in annual pollution emissions: [8] carbon monoxide emissions fell from 197 million tons to 89 million tons; nitrogen oxide emissions fell from 27 million tons to 19 million tons;
