What killed the rats was displacement of the oxygen in the air by the COs, some of which was exhaled by the rats. LOL First, I don't see anything to laugh about when life is taken. Second, what killed the rats was the high CO2 concentration in their blood stream. They did with maybe 15 seconds, which is far to fast for the oxygen to get depleted. CO2 is an acid. It gets converted to carbonic acid in the blood (HCO3- + H+ when the CO2 dissolves in blood). It causes the blood pH to drop to low levels. This is what killed the rats. If there were 50% O2 and 50% CO2, the results would have been the same. Jeff mike "Jeff" <news (AT) googlemail (DOT) com> wrote CO2 is also a poison. When I was doing lab research, rats were euthanized with CO2. CO2 nearly posioned the astronauts on the Apollo 13 mission (according to the book _The_Lost_Moon_ by James Lovell). If the concentration of CO2 in your body goes up by 50%, your blood pH will go down and you will start breathing real fast (this is called respiratory acidosis). Jeff You in the medical field? I retired from that field. |

True but water like CO2 is not a pollutant. What is the percentage of CO2 in the atmosphere? ![]() |

Apparently more than you. One does not see me asking for a source every time something is posted with which I may disagree. If I see something with which I may disagree I do my own search for the facts ![]() |

100% of all peer review scientific papers in respectable journals conclude that humans contribute to global warming. The others were paid for by Exxon and people like George Bush. |
