What samples are collected and how preserved?

The forensic toxicology (the LAW5510-U7's clinical twin): the poisons' medical science — the diagnosis, the treatment, the detection, the medico-legal interpretation. The classification(the exam's faces):1. By the origin: the corrosives (the acids-alkalis); the irritants (the metals — the arsenic, mercury; the plants — the castor, croton); the neurotoxins (the opioids, the sedatives, the alcohols); the asphyxiants (the gases of U4.1).2. By the use-and-case: the homicidal poisons (the odourless-and-tasteless preference — the arsenic's historic infamy); the suicidal (the accessible — the pesticides: the South Asian epidemic of the organophosphates); the accidental (the household's-and-occupational); the stupefying (the robbery-facilitation: the datura's lore — the "road of roses" cases).3. By the action's speed (the acute-vs-chronic of the LAW5505-U7's toxicologycompanion).
