1. Toxic

2. Toxic
This is the adjective applied to any substance able to cause injury to living organisms as a result of physicochemical interaction. See toxicity .

3. Toxic shock syndrome
Acute shock resulting from host response to an exotoxin produced by Staphylococcus aureus .

4. Toxic shock syndrome
Toxic shock syndrome is characterized by high fever, vomiting, and watery diarrhea. In severe cases, patient manefest signs of shock. Toxic shock syndrome could be caused by toxin produced by the bacterium Staphylococcus aureus in which case the female patient has been using tampons and symptoms appear within 5 days of the onset of menstruation. However, toxic shock syndrome could be caused by other means unrelated to Staphylococcus or the use of tampons.

5. Toxicant
This descriptor is applied to any substance which is potentially toxic. See toxicity .

6. Toxicity
The term "toxicity" is used in two different senses. * Capacity to cause injury to a living organism; * Any adverse effects of a chemical on a living organism (see adverse effect ). The severity of toxicity produced by any chemical is directly proportional to the exposure concentration and the exposure time. This relationship varies with the developmental stage of an organism and with its physiological status.

7. Toxicity assessment
This is the process of defining the nature of injuries that may be caused to an organism by exposure to a given chemical and the exposure concentration and time dependence of the chemically induced injuries. The aim of the assessment is to establish safe exposure concentration limits in relation to possible time of exposure.

8. Toxicity test
Controlled laboratory test to determine the toxicity of a chemical to an organism in terms of specific chemical concentrations. An acute toxicity test establishes the concentration required to kill a predetermined proportion of test organisms within a relatively short period of time, typically 4 d or less. A chronic toxicity test reveals the effects of a sublethal concentration applied throughout all or part of the life cycle.

9. Toxicokinetics
A subfield of toxicology that studies how toxin s are absorbed by, metabolized by, and eliminated from the bodies of living things.

10. Toxicology
The scientific study of the chemistry, effects, and treatment of poisonous substances.
