The prevalence of carbon monoxide poisoning is 鈥渧astly underestimated鈥�
because doctors fail to recognise the symptoms caused by long-term, low-level
exposure to the gas, according to the British charity Carbon Monoxide Support.
The group this week released a study of 77 people exposed to low levels of CO
over several years from sources such as poorly ventilated gas heaters. The
researchers found evidence of serious problems, such as memory loss and muscular
pain, that persisted even after the source of the poison was removed.
