Selective reaction of the body to substances that are foreign to it, or that the immune system identifies as foreign, shown by the production of antibodies and antibody-bearing cells or by a cell-mediated hypersensitivity reaction.
Industry:Biology; Chemistry
Semiochemical that is produced by one organism inducing a response in an organism of another species that is unfavorable to the emitter.
Industry:Biology; Chemistry
Sequence in the promoter region of a gene that regulates expression of that gene through interaction with a trans-acting factor.
Industry:Biology; Chemistry
Sequence of steps in which (a) a multistage model is fitted to tumor incidence data; (b) the maximum linear term consistent with the data is calculated; (c) the low-dose slope of the dose-response function is equated to the coefficient of the maximum linear term; and (d) the resulting slope is then equated to the upper bound of potency.
Industry:Biology; Chemistry
Sequence of transfer of matter and energy in the form of food from organism to organism in ascending or descending trophic levels.
Industry:Biology; Chemistry
Sequential oxidation of ammonium salts to nitrite and nitrate by micro-organisms.
Industry:Biology; Chemistry
Serious illness which is a consequence of consumption of toxic bivalve shellfish (mollusks) such as mussels, oysters and clams that have ingested, by filter feeding, large quantities of micro-algae containing brevetoxin; symptoms include gastroenteritis; rectal burning; paresthesias of the face, trunk, and limbs; myalgias; ataxia; vertigo; and reversal of hot/cold sensation.
Industry:Biology; Chemistry
Serious illness which is a consequence of consumption of toxic bivalve shellfish (mollusks) such as mussels, oysters and clams that have ingested, by filter feeding, large quantities of micro-algae containing saxitoxin or its derivatives.
Note: Initially there is tingling, numbness and burning of the tongue and lips, which spreads to the face, neck, arms, fingertips, legs and toes and this is followed by weakness of the upper and lower limbs, loss of motor coordination and, in severe cases, paralysis.
Industry:Biology; Chemistry
Set of inherent properties of a substance, mixture of substances or a process involving substances that, under production, usage or disposal conditions, make it capable of causing adverse effects to organisms or the environment, depending on the degree of exposure; in other words, it is a source of danger.
Industry:Biology; Chemistry
Sets of atmospheric concentrations and exposure times that are associated with specific effects of varying degrees of pollution on man, animals, vegetation, and the environment in general.
