The Toxicology is the branch of science that deals with the
adverse effects of chemicals on living organisms and leads to fatal condition
in living organism.
Toxicology is interface of
chemistry and biology.
Pharmacology: therapeutic effect
Toxicology: toxicosis or disease effect
Food toxicology deals with physical, chemical and biological properties of food particles and detection of toxic substances in food, and their diseases and infections.
Pharmacology: therapeutic effect
Toxicology: toxicosis or disease effect
Food toxicology deals with physical, chemical and biological properties of food particles and detection of toxic substances in food, and their diseases and infections.
Some food items are poisonous and
some are medicinal, stimulation, hallucinatory, or narcotic effects.
Toxicology in two categories:
basic and Fundamental. Fundamental work on the molecular and biological
processes of toxic substances is called Basic toxicology. Applying scientific
knowledge to practical problems is called Applied Toxicology.
Toxicology vs. Risk analysis: In
majority of Risk analysis only the applied toxicology is used to examine
whether there is the presence of chemical, natural and anthropogenic is used.
Risk analysis is broadly classified to include Risk assessment, Risk
characterization, Risk communication, Risk management. The role of toxicologists performs scientific tests on bodily fluids and
tissue samples to identify any drugs or chemicals present in the body. ... As
part of a team investigating a crime, a forensic toxicologist will isolate and
identify any substances in the body that may have contributed to the crime,
such as: Alcohol.
Toxicology is a discipline,
overlapping with biology, chemistry, pharmacology, and medicine, that involves
the study of the adverse effects of chemical substances on living organisms and
the practice of diagnosing and treating exposures to toxins and toxicants.
Human health risk assessment:
Predictive modelling of the toxicology to human health posed by the exposure to
toxicants. • For constituents that are systemic toxicants, the threat can be
expressed in terms of a hazard quotient. • Hazard Quotient = Dose ÷ Toxicity
Factor. Systemic toxicity is a threshold phenomenon. – Increasing exposure
(dose) of a chemical will cross a threshold when biological effects will start
to occur. – The dose is the total dose attributable all routes of
exposure. Dose is modeled with the following general equation
(unit conversion factors are used as needed): Dose = CC × CR × EF ÷ (BW × UCF)
• CC — constituent • CR — contact rate • EF — exposure frequency. • BW — body weight.
• UCF — unit conversion factor.
