The Facts on Arsenic | Dartmouth Toxic Metals

The effects of arsenic poisoning differ depending upon whether the exposure is acute – a large dose in a short period of time – or chronic – lower doses over an extended period of time. At a very high, single dose arsenic can cause severe shock, general paralysis, delirium and then death within a few hours.
