There are so many harmful chemicals in our planet, we must rely on toxicologist to figure out what they are, how much is lethal they are and how to dispose of them. The toxicologists not only they do to figure out what chemical makeups, but they also discover the treatments for poisoning ingestion and detection As we all know toxicology is the study
of poisons, came from the Latin word of toxicus (which means poisonous).
Toxicology
is pre-eminently an applied science, dedicated for the enhancement of quality
of life and for the protection of the environment. Poison it is any substance
that can causes a harmful effect when administered. Poison is also quantitative
concept, for almost any substance that being harmful at some doses but, at the
same time, being without harmful effect at some lower dose. Toxicity is a substance
that is poisonous or can cause of injury.Toxic term relates to
poisonous or deadly effects on the body by inhalation, ingestion, or
absorption, or by direct contact with a chemical. Toxicant used when talking about toxic
substances that are produced by product of human-made activities.
There are 6 major disciplines of toxicology such as:
- Descriptive Toxicologist
- Mechanistic Toxicologist
- Clinical Toxicologist
- Environmental Toxicologist
- Regulatory Toxicologist
- Forensic Toxicologist
A.
Heavy Metals- use by humans plays an important role in determining their
potential for health effects. Effect on health, by increasing the presence of
heavy metals in air, water, soil, and food, and changing the structure of the
chemical.
B.
Solvents and Vapors-Everyone
is exposed to solvents, vapors may pose a threat to
the population.
C. Radiation and Radioactive Materials- release and propagation of energy in space or through a material medium in the form of waves.
D.
Dioxin/Furans (or TCDD) - by-product of chlorine processing in
paper producing industries.
E.
Pesticides - described as any physical, chemical, or biological agent that will kill an undesirable plant or animal pest.
F.
Microbial toxins -Bacteria, fungi and algae are the microorganisms typically
associated with microbial toxin production.
G.
Mushroom toxins-produce a family of cyclic octapeptides that they called amanitins.
H. Plant Toxins-made by plants can be lethal. One of the main toxic proteins is "ricin" from the seeds of castor bean plant.
I. Animal Toxins-Venomous animals are defined as those that are capable of produce a poison that can deliver by toxin through biting or stinging.
