Branch of biology which studies the interactions between living organisms and all factors (including other organisms) in their environment: such interactions encompass environmental factors which determine the distributions of living organisms.
Industry:Biology; Chemistry
Branch of chemistry concerned with measuring and studying rates of chemical reactions.
Industry:Biology; Chemistry
Calculated concentrations of a substance, typically a pesticide, in various environmental compartments based on calculations using maximum-exposure scenarios.
Note: EEC models assume a maximum number of applications per growing season at the maximum rate of application according to the application methods stated on the product label.
Industry:Biology; Chemistry
Calculation, based on quantitative observations in exposed test species or in vitro test systems, of predicted dose-effect and dose-response relationships for a substance in humans and other biota including interspecies extrapolations and extrapolation to susceptible groups of individuals.
Note: The term may also be used for qualitative information applied to species or conditions that are different from the ones in which the original investigations were carried out.
Industry:Biology; Chemistry

Industry:Biology; Chemistry
Causing inflammation following immediate, prolonged or repeated contact with skin, mucous membrane or other tissues.
Industry:Biology; Chemistry
Cell or organism with the genetic material packed in a membrane-surrounded structurally discrete nucleus and with well-developed cell organelles.
Note: The term includes all organisms except archaebacteria, eubacteria and cyanobacteria (until recently classified as cyanophyta or blue-green algae).
