What OECD 420?
The method provides information on hazardous properties and allows a substance to be classified for acute toxicity. Only moderately toxic doses are used. Research models are dosed in a stepwise procedure using fixed doses.
What do toxicologists use?
Working in a lab, the forensic toxicologist performs tests on samples collected by forensic pathologists during an autopsy or by crime scene investigators. They use highly sophisticated instruments, chemical reagents and precise methodologies to determine the presence or absence of specific substances in the sample.
What is the first rule of toxicology?
All things are poison, and nothing is without poison, the dosage alone makes it so a thing is not a poison. “The dose makes the poison” (Latin: dosis sola facit venenum ‘only the dose makes the poison’) is an adage intended to indicate a basic principle of toxicology.
