Toxic chemical means any chemical which through its chemical action on life processes can cause death, temporary incapacitation, or permanent harm to humans or animals. This includes all such chemicals, regardless of their origin or of their method of production, and regardless of whether they are produced in facilities, in munitions or elsewhere.
The term toxicity is very widely used in the safety context. It is used in two contrasting senses: to denote the capacity to cause harm to a living organism, and to indicate the adverse effects caused by a chemical.
Toxicology is a science which studies all kinds of poisons and their effects on live organisms.
Transference number of an ion is the fraction of the total current that is carried by that ion during electrolysis. Different ions carry different fractions of the current because different ions move at different speeds under the same potential gradient. In general, a cation and an anion differ in the amount of current they can carry during electrolysis.
Transitional temperature is a temperature at which the crossing from one kind of crystals to another appears to be of the same matter (polymorphy).
Transmittance (τ) is the ratio of the radiant or luminous flux at a given wavelength that is transmitted to that of the incident radiation. Also called transmission factor.
Transmutation is the conversion of one element into another by a process taking place in the nucleus.
Transuranium elements are elements with an atomic number higher than 92 (uranium’s atomic number). Transuranium elements are unstable and occur in extremely low concentrations in nature. Most are made artificially.
