Types of poison That may help to account for the wide range of toxic effects of arsenic. The most obvious and immediate cases of arsenic poisoning have occurred when a large dose of arsenic is taken (or given!) in a short period of time. This kind of exposure is called acute arsenic poisoning, and some of the symptoms are: 1  Vomiting. 2  Throat and stomach pain. 3  Bloody diarrhea. 4  Eventually it may lead to shock, seizure, coma and death.

Arsenic Studies in laboratory animals indicate that administration of trivalent inorganic arsenic such as As2O3 and arsenite initially results in higher levels in most tissues than does the administration of pentavalent arsenic. However, the trivalent form is more extensively methylated, leading to similar long-term excretion.

What's your poison? Easy to buy, almost tasteless and lethal in tiny doses, arsenic was once regarded as the perfect murder weapon â especially in the hands of women In fact, the element called arsenic passes quite safely through the human body provided it remains in that elemental state. Arsenic trioxide, or white arsenic (which most people mean when they refer simply to arsenic), is a very different proposition. A harmless-looking powder, resembling flour or sugar at a quick glance, white arsenic is tasteless, easily dispersed in hot food and drink, and fatal in tiny doses.

Because resistance varies from one individual to another, the lethal dose represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die.The lethal concentration is a lethal dose measurement used for gases or particulates.he lowest lethal dose (LD Lo) is the least amount of drug that can produce death in a given animal species under controlled conditions. The dosage is given per unit of bodyweight (typically stated in milligrams per kilogram) of a substance known to have resulted in fatality in a particular species.
