Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell or an organ such as the liver.

Classification criteria for substances 2. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell or an organ such as the liver. The exposure level or dose of an agent above which toxicity or adverse health effects can occur, and below which toxicity or adverse health effects are unlikely.

The Threshold Of Toxicological Concern (Ttc) Approach Is A Pragmatic, Scientifically Valid Methodology To Assess The Safety Of Substances Of Unknown Toxicity Found In Food (Efsa And Who, 2016A).


Generally, the lower the toxic loc value for a substance, the more toxic the substance is by inhalation*. Chemicals can be allocated to one of five toxicity categories based on acute toxicity by the There is a threshold below which relatively little damage occurs from exposure, and above which the damage increases dramatically.

Once The Threshold Exposure Level Has Been Established, You Simply Need To Compare The Actual/Predicted Exposure Level With The Threshold Value To.


For example, toxic agents may be chemical (such as cyanide), physical (such as radiation) and biological (such as snake venom). It may be chemical, physical, or biological in form. Threshold of toxicological concern (ttc) of genotoxic carcinogens.
