7.3 Acute and Chronic Toxicity

The acute: the single-or-short exposure (the overdose, the homicidal dose, the accidental); the symptoms' suddenness; the emergency's medicine-and-autopsy faces. The chronic: the repeated exposure (the occupational — the metals; the domestic — the chronic arsenic; the drug dependence); the accumulation's diseases; the forensic's slow-poison lore (the historic homicides' method — the modern detection's answer). The Nepal faces: the pesticide suicides' tragedy (the organophosphates' access — the public-health-and-legal questions); the chronic exposures (the water's arsenic-and-lead faces).
