Carbon dioxide and hydrogen may form from organic materials, moisture is outgassed by polymers and amine-cured epoxies outgas ammonia. Formation of cracks and intermetallic growth in die attachments may lead to the formation of voids and delamination, impairing heat transfer from the chip die to the substrate and heatsink and causing a thermal ...
These range from the toxic effects of oxygen at high partial pressure, [40] through buildup of carbon dioxide due to excessive work of breathing and increased dead space, [41] to the exacerbation of the toxic effects of contaminants in the breathing gas due to the increased concentration at high pressures, [42] and include effects on the ...
During strenuous exercise the production rate of carbon dioxide can increase more than tenfold over the production rate during rest. Carbon dioxide is dissolved in the blood and elimination is by gas exchange in the lungs during breathing. [10] Hypercapnia is generally caused by hypoventilation, lung disease, or diminished consciousness.

The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2 ) at increased partial pressures . Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs , and eyes.
The Haldane effect: most carbon dioxide is carried by the blood as bicarbonate, and deoxygenated hemoglobin promotes the production of bicarbonate. Increasing the amount of oxygen in the blood by administering supplemental oxygen reduces the amount of deoxygenated hemoglobin, and thus reduces the capacity of blood to carry carbon dioxide.
Coal is the largest contributor to the human-made increase of carbon dioxide in Earth's atmosphere. There are severe health effects caused by burning coal. [2] [3] [4] Worldwide 25 people die early for each terawatt hour of electricity generated by coal, around a thousand times more than nuclear or solar. [5]
