forensic science: introduction of poison

introduction of poison

INTRODUCTION OF POISON

Forensic toxicology will be defined because the discipline of studying under a forensic profile the pathologies induced by xenobiotics.

Xenobiotics are poisonous materials, narcotics, abusive drugs, toxic substances, pest control chemicals and chemicals that are used in agriculture, sedating substances and, in element, food items.

DEFINITION OF POISON:

Any substance is harmful to the living organism. consistent with German-Swiss Physician Paracelsus

Everything is poisoned, there's none that is not a poison, the dose makes it a poison and differentiates it from a drug.

Thus, it's a substance (solid, liquid or gas), introduced or brought into contact with any part, which will produce a pathological state or death.

CLASSIFICATION:

BASED ON-

1.Supported Mode Of Action Of Poisons.

2.Chemical Properties And Method Of Isolation From Tissues And Other Biological Materials.

POISON ALSO CAN BE CLASSIFIED INTO SIX GROUPS:

1. The poisons in gaseous substances- Inhalation of that cause Intoxication.

Some example is- The carbon monoxides or the hydrogen sulphides ethylic ethers and chloroform.

2. Poison in an absolutely liquid condition at danger of volatility

E.g.- Benzenes and its by-products, glycol, aldehydes and crucial oils of some trees, etc.

3. Acids and Highly Basic Substances

E.g.- Hydrochloric, sulphuric and nitric acids, sodium or potassium hydrates, etc.

4. Inorganic anions

E.g.- permanganates, chromates.

5. Metals or salts of metals

E.g.- Arsenic, thallium, mercury, lead.

6. some organic/Inorganic compounds of acidic, basic and neutral nature

E.g.- Most drugs of synthesis, alkaloids, narcotic, insecticides, agrochemicals, etc

forensic dna analysis

Forensic DNA analysis: The DNA, that is present in most living organisms. we have some unique method called DNA profiling in (nucleus of DNA) and forensic DNA analysis or fragment analysis by which we can analyze the genetic material of an organism. These substances include the human body like blood or semen that may be seen by the oculus if in sufficient quantity, as an invisible amount of the identical fluid or of other substance like skin cells in sweat or fingermarks. what are DNA sequence analysis and DNA profiling in forensic science? The chemical stability of DNA is beneficial for forensic genetics because it means the DNA of a biological sample is also analyzed (by a genetic analyzer ) long after it absolutely was deposited at a criminal offence scene. This has been very useful, as an example in cold causes long after storage and with the arrival of the latest analytical methods. If the DNA is preserved under the correct condition and using the acceptable methods, and ...
