Decomposition
See also degradation. |
分解
見degradation. |
Degradate
Chemical product resulting from degradation of
a pesticide |
分解產物
農藥分解後之化學產物。 |
Degradation
Process by which a pesticide is broken down to
simpler structures through biological or abiotic
mechanisms. Synonyms include breakdown and
decomposition. See also biodegradation,
mineralisation. (OECD) |
分解
農藥經由生物或非生物機轉降解為較簡單結
構分子的作用。 |
Desorption
Depletion of one or more components in an
interfacial layer. (Gold, 1993) |
解吸附件用
部份組成自界面層脫離之現象。 |
Detoxification
Processes of chemical modification which make
a pesticide less toxic- (afier Duffus, 1993) |
解毒作用
改變農藥化學結構以致減低其毒性的作用． |
Diluent
Limnd or solid rnaterial used to dilute a
concentrated pesticide formulation prior to
application.
Most commonly water for spray
application. |
稀釋劑
農藥施用前用於稀釋農藥成品之液體或固
體。如用水來稀釋噴灑型農藥。 |
Dislodgeable residue
Portion of a pesticide residue on treated
vegetation that is readily removable. Generally
measured by the residue removed when leaf
discs are shaken briefly in water or a weak
solvent and may be used an index for risk to
farm workers. |
可去除殘留量
可自經農藥處理之蔬菜中去除之殘留量。-
般以水或溶劑將葉片稍事情洗．將可去除之
殘量視為可去除殘留量並用以評估農藥對農
人之危害。 |
Dissipation
General term describing the loss of pesticide
residues from an environmental compartment
due to degradation and/or transfer to another
environmental compartment. |
消散
用來形容農藥任環境成員中之消退或轉移之
通用話。 |
Dissipation time 50% (DT50)
Time required for one-half the initial quantity or
concentration of a pesticide to dissipate from a
system. No assumption as to the rate equation is
made. See also half-life. |
半衰期
農藥之量或濃度消退至起始時之二分之一所
需之時間。 |
Dispersible grannie
See water-dispersible granule. |
分散性粒劑
同水分散性粒劑。 |
Dose-effect relationship
Graded relationship between the dose of the
pesticide to which the organism is exposed and
the magnitude of a defined biological effect,
either in an individual organism or in a
populatiou. See also concentration-effect
relationship, (after Duffus, 1993) |
劑量與效應關係
農藥劑量與受其暴露之生物所產生之生物效
應程度間關係。可用於表達農藥對生物個體
或棲群之效應。 |
Dose-response relationship
Association between dose and the incidence of a
defined biological effect in an exposed
population. (after Duffus. 1993) |
劑量與反應關係
接受劑量之棲群所產生之生物反應與其暴露
劑量間之關係。 |
Drift control agent
Fomulant for reducing drift from spraying by
controlling the distribution of spray droplet
sizes and preventing production of excessive
fines. |
飄散控制劑
用以減少嘖藥時飄散之製劑成分，可控制霧
粒大小和避免產生大量微粒。 |
Dry weight basis
Pesticide residues are reported as if the residue
were wholly contained in the dry matter of the
sample, i.e. analytical result calculations are
corrected for ths water content of the test
sample. Residues in soils and feeds, and
maximum residue limits (MRLs) for foodstuffs
are expressed on a dry weight basis. |
乾重量基準
以樣品之乾重寫基準來表示殘留量，分析結
果經樣品之水含量校正。通常土壤、飼料等
之殘留量皆以乾重量基準表示。 |
