12.1 Analysis and Assessment of the Microcosm N-System
for OECD Standardization
Positioning of the various docimasy of the bioassay and the fundamental utility of
the microcosm for ecosystem impact assessments are shown in Figs. 12.1 and 12.2.
In addition to various factor analysis at the ecosystem level using the microcosm
N-system, the combination of the general interaction analysis through the use of a
simulated environmental microcosm (mesocosm) and the underlying interactions
analysis through both the two-species cultures and the single-species cultures, are
important for the advancement of ecosystem impact assessment. It is the microcosm
test that becomes essential for evaluating ecosystem impacts, including those on the
human body, based on the study of marmots. Additionally, although the docimasy
varies in various bioassays, the microcosm test remains at the core.
A procedure for assessing the impacts of chemical substances by culturing, data
collection, and branching-type analyses of variance using the microcosm N-system
docimasy is shown in Fig. 12.3. Specific examples of the evaluation in this docimasy
are shown below.

sterilizer, wood preservative, and formicide. The most susceptible creature, water
