Question

Viscera in toxicology stored in:

• A. Glycerine
• B. Rectified spirit
• C. Formalism
• D. Saturated salt solution

Answer 1

The Correct Option is D

Viscera, when stored for toxicological analysis, need to be preserved in a manner that prevents decomposition and contamination. The common method used involves saturation to inhibit bacterial growth and enzymatic activities which could alter toxicological findings. Out of the options provided, each has its own properties, but not all are suitable for preserving viscera intended for toxicological analysis.

• Glycerine: Often used as a preservative, but not suitable for toxicology as it might interfere with certain analyses.
• Rectified spirit: Good for reducing bacterial growth but volatile in nature and might cause extraction of volatile compounds, affecting the analysis.
• Formalin: An excellent tissue fixative, preserving structural integrity, but can affect the detection of certain toxins and is not preferred for toxicology.
• Saturated salt solution: Ideal for preserving biological tissues in toxicological studies. It maintains the sample's condition without interfering with chemical analysis, making it the standard choice.

Given these characteristics, the correct choice is:

Saturated salt solution
