Toxic substances and possibilities of their identification in biological materiał

Humań organism is exposed on continual exposition to contamination, which comes from the environment, food, cosmetics and items for daily use. Poisonings feature criminal, suicidal and terrorist character often. Despite thatthe toxicity of applied substances depends on physical and Chemical construction, fonn and route of administration, biological properties or detoxification possibilities of the organism, the dose is the most important factor, which determines the level of toxicity.

Toxicological analysis can be performed for every kind of samples, but blood is that materiał, which is used the most often in research. What is morę it’s often analyzed together with other fluids. Substances with toxic potential can cumulate in tissue and vitals or be excreted from the organism. Hair is also known as valuable materiał for research, it enables poison identification, even if ingestion of that substance was remote. Vitreous harvested from corpse is that materiał, which is often used in forensic toxicology. That materiał is less addictive to biochemical transformation, post-mortem decomposition processes or exogenous contamination, and location inside the eye is the only one reason of that.

The aim of that research is introduction with sources and metabolism of poison and the type of biological materiał, which is used in toxicological and criminalist analyzes.
