Property, the comparativity of validity and experimental result, test of the most confirmation request tested substance of these methods in entire test period
It can keep relative stability in system.If tested substance is relatively stable, toxic exposure experiment does not update within entire test period
Solution is carried out；It otherwise must be using the experimental method for regularly updating solution.Since maximum solution renewal frequency can only generally reach
It is necessary if its degradation half life is less than for 24 hours for the unstable tested substance of facile hydrolysis, volatile, easy photodissociation etc. to for 24 hours
By other way.This unstable tested substance belongs to " test difficult substances ", accounts among industrial chemistry substance and pesticide
Quite a few of body, an important factor for being the main bugbear of Ecology toxotest and influence test accuracy.
In addition, the chronic toxicities such as breeding, development and environment incretion interfering intoxicating period are generally longer, must cover
Biological major part life cycle or Life cycle.In order to reduce because tested substance degradation or loss to test bring deviation,
Study chemical substance chronic toxicity, the interfering Ecology toxotest of environment incretion it must also be ensured that test solution longer
Biological subject is exposed with more stable concentration in the toxotest period.
Due to above-mentioned many complicated, fine, special technical requirements, not yet occurs satisfactory equipment currently on the market
Or device, existing experimental method not only low efficiency, but also be difficult to cope with the testing requirement and change of unstability " difficult substances "
Substance chronic toxicity, the interfering Ecology toxicity of environment incretion is learned to study for a long period of time demand.This is tested chemical substance and section
It learns research and brings larger difficult and error.
