Carbon Monoxide (CO) monitoring

Carbon monoxide poisoning is the most common type of fatal poisoning in many industrialized countries. Carbon monoxide is a colourless, odorless and tasteless gas caused by the incomplete combustion of hydrocarbon fuels. Carbon monoxide is a toxic gas to the human body, when inhaled it binds to hemoglobin, myoglobin, and mitochondrial cytochrome oxidase reducing oxygen storage, transport and respiration in these organelles.

These can affect humans by causing low level symptoms such as headaches, nausea and dizziness leading up to vomiting and loss of mental/muscular control at high exposure and death in extreme cases.

Carbon monoxide as a pollutant is found in the ambient air as well as stack and naturally in background measurement. Carbon monoxide is a requirement for most ambient air monitoring projects including being one of the 6 criteria pollutants required for measurement by the U.S. EPA. Carbon monoxide is often measured in conjunction with Carbon Dioxide for Carbon emissions monitoring.
