identification Process of unambiguously
determining the chemical identity of a pesticide or metabolite in experimental
or analytical situations.
immobilisation
- Process leading to restricted mobility of a pesticide in plant or soil
due to strong binding.
- Incorporation of terminal pesticide degradates into complex
organic forms in microbial or plant tissue.
immunoassay Ligand-binding assay based
on antibodies capable of specific binding to the pesticide analyte. Most commonly
used in a competitive binding format where analyte molecules compete with
a specific antigen complex labelled for detection using a radioisotope (radio
immunoassay - RIA) or enzyme (enzyme-linked immunoassay - ELISA).
impurity By-product of the manufacture or
storage of a pesticide. Impurities require definition, evaluation and regulation
(if toxicologically significant).
increment sample An individual portion
(unit) of material collected by a single operation of a sampling device from
bulk materials or large units. (after Horwitz, 1990)
incurred residue Residue in a commodity
resulting from specific use of a pesticide, consumption by an animal or environmental
contamination in the field, as opposed to residues from laboratory fortification
of samples.
inert ingredient Formulant which
by itself does not add materially to effectiveness for the purpose for which
the preparation is intended e.g. solvent, emulsifier, diluent, carrier.
in-life phase Phase of a study following
treatment in which the test system is alive/growing.
integrated pest management (IPM)
Pest management system that, in the context of the associated environment
and the population dynamics of the pest species, utilises all suitable techniques
and methods in as compatible a manner as possible to maintain the pest populations
at levels below those causing economically unacceptable damage or loss. (FAO,
1988)
in-vitro 'In-glass', referring to use
of a cell line, microorganisms or biochemically active fraction derived from
an organism (e.g. hepatocytes) in laboratory studies of biological activity,
or metabolism or toxicity.
in-vivo Use of the whole living organism
in studies of biological activity, metabolism or toxicity.
kd See soil partition coefficient.
koc See soil organic partition
coefficient.
