Contributors in Toxicology
Toxicology
critical organ concentration of a substance
Biology; Toxicology
Mean concentration of a substance in the critical organ at the time the substance reaches its critical concentration in the most sensitive type of cell in the organ.
adsorption factor
Biology; Toxicology
Ratio of the amount of substance adsorbed at the interface of a condensed and a liquid or gaseous phase to the total amount of the substance available for adsorption.
bystander exposure
Biology; Toxicology
Liability of members of the general public to come in contact with substances arising from operations or processes carried out by other individuals in their vicinity.
chronic toxicity
Biology; Toxicology
1. Adverse effects following chronic exposure. 2. Effects which persist over a long period of time whether or not they occur immediately upon exposure or are delayed.
long-term toxicity
Biology; Toxicology
1. Adverse effects following chronic exposure. 2. Effects which persist over a long period of time whether or not they occur immediately upon exposure or are delayed.
asphyxiant
Biology; Toxicology
Substance that blocks the transport or use of oxygen by living organisms. Note: Examples include both physical (nitrogen gas) and chemical (carbon monoxide) asphyxiants.
active transport
Biology; Toxicology
Movement of a substance across a cell membrane against an electrochemical gradient, in the direction opposite to normal diffusion and requiring the expenditure of energy.
