Întrebare: Ce sunt cianurile?
Răspuns: Cianurile sunt substanțe chimice care conțin cel putin un grup cian (C≡N). Multe cianuri sunt extrem de toxice. Dintre cianuri, compusul cel mai periculos este acidul cianhidric, care, pentru că este un gaz la temperatură și presiune normală, poate fi inhalat. Ingestia orală a unei cantități foarte mici – de obicei 200 miligrame – de cianură solidă sau soluție poate duce rapid la moarte în câteva minute.
