Carbon Monoxide Effects

Contrary to what many publications would have you believe, there is growing evidence that lingering problems from carbon monoxide poisoning has very real and sometimes long-lasting effects on the body.  This may occur even at relatively low levels of exposure.

The following chart lists the symptoms and percentage of respondents who demonstrated those symptoms.  Unfortunately the study did not track the exact levels of exposure, other than calling them acute.
