Career in Toxicology

CAREER IN TOXICOLOGY

Toxicology is a branch of biology, chemistry and pharmacology concerned with the study of the adverse effects of chemicals on living organisms. It also studies the harmful effects of chemical, biological and physical agents in biological systems that cause damage in living organisms upto different extent. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage (acute or chronic); the route of exposure, the species, age, sex and environment.

Toxicology involves observing and reporting symptoms, mechanisms, detection and treatments of toxic substances, in particular relation to the poisoning in humans. It includes environmental agents and chemical compounds found in nature, as well as pharmaceutical compounds that are synthesized for medical use by humans. These substances may produce toxic effects in living organisms including disturbance in growth patterns, discomfort, disease and death.

The goal of toxicity assessment is to identify adverse effects of a substance. Adverse effects depend on two main factors:i) Routes of exposure (oral, inhalation, or dermal) and ii) Dose (duration and concentration of exposure).

To explore dose, substances are tested in both acute and chronic models. Generally, different sets of experiments are conducted to determine whether a substance causes cancer and to examine other forms of toxicity. Toxicity experiments may be conducted in vivo (using the whole animal) or in vitro (testing on isolated cells or tissues), or in silico (in a computer simulation).

Branches of Toxicology

There are several branches of toxicology, which focus on particular aspects of toxicology. These are:Aquatic toxicology, Medical toxicology, Chemical toxicology,Environmental toxicology,Clinical toxicology, Eco-toxicology, Forensic toxicology, Occupational toxicology, Regulatory toxicology, and Toxicogenomics.

Toxicology and career opportunities

As a profession, toxicology is very important, as people are concerned about the potentially harmful effects of products, medications and the chemicals they're exposed to in their daily lives Without toxicologists we would not understand what could potentially poison or harm living things as well as the environment around us. Toxicologist is one who explores the effects of chemicals on living organisms.. Toxicology covers two main areas- One deals with the effects that toxic materials have on humans and the other with their impact on the environment.

Toxicology is an enormous field of study that has so many subdivisions. Aspirants can pursue graduate or postgraduate courses in their respective areas of interest.

Major Courses:

Toxicology is a field that requires candidates from various interdisciplinary branches like biology, mathematics, veterinary sciences, pathology, physiology, immunology, and genetics. Not only do toxicologists figure out chemical makeup, they use their knowledge of biology, chemistry, and the environment to devise strategies to reduce or control exposure to these chemicals. To become a toxicologist one must take science stream in senior secondary level. After that one can opt for a bachelor degree in botany, chemistry, zoology, biochemistry, medicine, veterinary science, pharmacy, biochemistry, biotechnology, microbiology, environmental biology or some other life science based discipline.

Science graduates can make career in their interests. Various degree/diploma courses are conducted by various universities/institutions in India and abroad. One can pursue different courses/degree in the field of toxicology. Few major courses are given below:

B.Sc.- in Toxicology or Biological sciences
M.Sc.- in Toxicology or Environmental Toxicology
PG Dip. - in Eco-toxicology, etc.
Short-Term Courses/ Diploma - in Aquatic ecology, Xenobiotics, Auditor, etc.
Ph.D. - in Toxicology or environmental toxicology

Major Entrance Exams conducted in Toxicology are: (a)All India Postgraduate Medical Entrance Examination AIPMT (b)Combined Biotechnology Entrance Examination (c)Delhi University Medical Entrance Test (DUMET) (d)National Institute of Mental Health and Neuro Sciences Entrance Exam (e)National Institute of Pharmaceutical Education and Research Joint Entrance Examination – NIPER JEE (f)Punjab Medical Entrance Test and (g)Rajiv Gandhi University of Health Sciences Post Graduate Entrance Test.
