Study Notes
Chloroform (CHCl3)
- Composed of 1 Carbon, 1 Hydrogen, and 3 Chlorine atoms.
- Characterized by a sweet smell.
- Physiological effects include unconsciousness and potential death.
- Detection involves chemical extraction from body samples followed by chemical testing to reveal its distinct smell.
Methanol (CH3OH)
- Consists of 1 Carbon, 4 Hydrogen, and 1 Oxygen atom.
- Causes blindness and death, with effects resembling ethyl alcohol intoxication.
- Metabolized in the liver into formaldehyde and formic acid, which damage cells and attack the optic nerve, leading to blindness.
- Ultimately fatal due to lung tissue damage.
- Detection requires distillation to isolate from other substances, followed by chemical testing for formaldehyde and formic acid.
- Notable for being invisible in daylight when burned.
Cyanide (NaCN)
- Contains 1 Sodium, 1 Carbon, and 1 Nitrogen atom.
- Known for a bitter almond smell, not detectable by everyone.
- Causes convulsions and death by preventing oxygen transport in the body.
- Detection is done through the Prussian blue test, where chemical reactions produce a characteristic blue color.
Arsenic (As)
- Commonly found as arsenic trioxide (As₂O₃), also known as white arsenic.
- Symptoms include abdominal pain, seizures, and organ failure, leading to death.
- Interferes with cellular metabolism and slows decomposition of bodies.
- Detection uses the Marsh test, which involves treating a sample with acid and zinc; presence of arsenic results in a metallic stain.
Mercury (Hg)
- Includes two forms: Bichloride of mercury (HgCl₂) and mercurous chloride (Hg₂Cl₂).
- Appearance resembles shiny silver water but disintegrates upon contact.
- Causes a range of symptoms including irritability, memory issues, and mercurial tumors, potentially leading to death.
- Detection achieved through chemical precipitation to isolate mercury from the body sample.
- Historically linked to "mad hatter's disease," affecting hatmakers who used mercury in their work.
Carbon Monoxide (CO)
- Notable for being odorless, tasteless, and invisible; can lead to distinctive pink skin coloration.
- Has toxic effects such as drowsiness, headaches, confusion, and severe coordination loss.
- Blood appears bright red as a result of carbon monoxide binding with hemoglobin, impairing oxygen transport.
