Contributors in Toxicology
Toxicology
count median diameter
Biology; Toxicology
Calculated diameter in a population of particles in a gas or liquid phase above which there are as many particles with larger diameters as there are particles below it with smaller diameters.
chromosome
Biology; Toxicology
Self-replicating structure consisting of DNA complexed with various proteins and involved in the storage and transmission of genetic information; the physical structure that contains the genes.
chronic toxicity test
Biology; Toxicology
Study in which organisms are observed during the greater part of the life span and in which exposure to the test agent takes place over the whole observation time or a substantial part thereof.
long-term toxicity test
Biology; Toxicology
Study in which organisms are observed during the greater part of the life span and in which exposure to the test agent takes place over the whole observation time or a substantial part thereof.
antiresistant
Biology; Toxicology
Substance used as an additive to a pesticide formulation in order to reduce the resistance of insects to the pesticide, e.g., an antimetabolite that inhibits metabolic inactivation of the pesticide.
auxotroph
Biology; Toxicology
Organism unable to synthesize an organic molecule which is required for its growth: when the compound is given to the organism with the other nutrients it requires, growth of the organism may occur.
carcinogen
Biology; Toxicology
Agent (chemical, physical or biological) which is capable of increasing the incidence of malignant neoplasms, thus causing cancer. Note: Annex 3 describes the classification systems for carcinogens.
