FATE OF POISONS
1. In large amount poison is vomited or passed out in stools ( diarrhea) .
2. If absorbed excreted unchanged partly or completely metabolized converted to another active compound prior
to metabolism (biotransformation) may be detected in original form
![Page 14: IN THE NAME OF ALLAH THE MOST MERCIFUL](https://reader036.vdocuments.mx/reader036/viewer/2022062310/56816530550346895dd7b4f7/html5/thumbnails/14.jpg)
may be detected in intermediate product in tissues e.g liver & bile .
may be detected in excreta e.g urine.
may be present in epidermis,nails, hair, e.g arsenic.
bony skeleton may hold poisons like arsenic ,lead, radioactive isotopes.
