📖 1. Scope of Analytical Toxicology

🔑 Key Concepts & Definitions

• Analytical toxicology : Concerns the detection, identification, and measurement of drugs, other foreign compounds called xenobiotics, and their metabolites in biological organisms or biological samples.

★ Must-know

• Analytical toxicology can contribute to the diagnosis, management, and, in some cases, prevention of poisoning.

Further detail

📌 Effective analytical toxicology requires basic knowledge of clinical and forensic toxicology.

💡 Memory Hook

Detect → identify → measure

📖 2. Roles and Analytical Reliability

★ Must-know

📌 Some emergency analyses are performed for clinical purposes but have clear forensic implications and therefore require a high degree of analytical reliability.

• Over the last 25 years, substantial progress has been made in methods for detecting, identifying, and measuring drugs and other poisons in biological fluids or environmental samples.

• Progress in analytical methods has improved the scope and reliability of analytical results.

Further detail

• The value of some emergency analyses and their contribution to therapeutic intervention have been clarified.

💡 Memory Hook

Improved methods → broader and more reliable analytical results

📖 3. Classification of Toxic Substances

★ Must-know

📌 Toxic substances are difficult to classify chemically by function or mode of action because many substances would belong to several classes.

📌 Toxic substances can usefully be categorized according to their intended exposure routes, physicochemical properties, or uses.

• Toxic substances may be: natural products, synthetic organic chemicals useful to society, by-products of industrial processes and waste disposal

Further detail

• General toxicology distinguishes three principal types of toxic substances.

💡 Memory Hook

Chemical classification is difficult, whereas exposure-route, physicochemical, and use-based categories remain useful
