etc.

1. Accidental toxicants

2. Suicidal toxicants

3. Homicidal toxicants

4. Stupefying toxicants

examples: Liquid bleach Methyl alcohol Tablets Contaminated food Animal bites such as: snake bite, wasp,

etc.,

Examples:ArsenicHydrogen cyanideOpiumOleanderPotassium cyanidePowderd glass

Examples: Arsenic Aconite Croton tiglium Opium Dhutoora Khuchla thallium

Examples: Chloroform Sulphuric acid Chloral hydrate Olax(fish stupefying) Dhatura Cannabis Ergot Chloral hydrate

1. Corrosive poisons or toxicants

2. Irritant poisons or toxicants

PROPERTIES:

Highly active Highly irritant Produce inflammation Ulceration Tissue and organ damage

MINERAL ACIDS e.g., HNO3 HCL H2SO4 ORGANIC ACID e.g., formic acid acetic acid

oxalic acid Hydrocyanic

acid CONC. ALKALIES e.g., caustic soda caustic potash

This is dilute form of corrosive poison.It act as an irritant.

It produces:-Irritation-Burning-Abdominal pain-Vomiting-Diarrhoea

NON-METALLICBromineIodine

chlorine Phosphorus

METALLICCopperLeadMercuryArsenic

VEGETABLECastor oil seedDhutura seedsCroton tiglium

ANIMALSnake venomInsect venom -Bees -Wasps -Ants

MECHANICALGlass Diamond (powdered form both)

1. neurotic toxicants

2. spinal cord toxicants

3. Peripheral nervous system toxicants

4. Cardiac poisons

5. Asphyxiants

6.hepatotoxicants alcohol,aflotoxins,carbon tetrachloride, bromobenzene 7.Nephrotoxicants Metals,chloroform

“Affects the central nervous system”

SOMNIFEROUS – induces sleep or sleep like conditions.

e.g., snake biteSnake venomOpium & it’s byproducts

INEBRANT - produces two sets of symptoms: i. excitement ii. Narcosis

e.g., alcohol methyl alcoholfuels

“Effects spinal cord”

Examples:- Belladona- Aconite- Dhatura

Examples:

Conium and CurareFrom conium Alkaloides are producedi.e.,

ConclineMethyl Concline

Examples:

Snake venom Bee venom Scorpion venom Oleander seeds Castor oil seeds Nicotine from tobacco Cocaine Aconite Cannabis sativa
