Arsenic Hair Body as a whole Dinitrophenols .... Exposure to a toxic agent does not necessarily result in poisoning. A definite concentration must result i n vital tissues before irreversible toxic effects occur. The most effective method of treating poisoning is to prevent its occurrence. This having failed, the sine qua non is removal of the unabsorbed portion, or alteration chemically or physically so that the absorbed portion does not remain i n contact with cells i n toxic amounts. Unfortunately, most of the antidotal treatment of poisoning from agents of economic importance is symptomatic—that is, physiologic i n nature.
