Causal characteristics and the types of evidence that support them. Table 5-3, Table 5-4

Example Stressor-Response Relationships Table as part of CADDIS Volume 1 stressor identification section.

This page is about how to diagnose causes and gives some examples to help risk assessors.

Overview, details of eliminating improbable causes

This page gives an overview about how to score the evidence when doing stressor identification.

An overview for listing candidate causes

An overview, listing stressors as candidate causes

A table containing a list of candidate causes used for stressor identification in Bogue Homo, Mississippi.

An overview of stressors from studies

This is a list of stressors that can potentially cause biological impairment and the source reference.

Figure 3-11 illustrates the concept of looking at symptoms of the fish to determine what the impairment might be.

Figure 3-10 illustrates the concept of using experience and knowledge to verify hypothesis' which can help to strengthen the case too.

Figures 3-8a and b illustrate the concept of the type of evidence "laboratory tests of site media".

Figures 3-7a and 3-7b illustrates the different outcomes when you remove or don't remove the impairment.

Figure 3-4 illustrates how to derive and evaluate evidence of exposure or biological mechanism.

Figures 3-5a and Figure 3-5b illustrate the concept of the Causal Pathway type of evidence that support or refute the case.

Figures 3-6a and 3-6b illustrate the concept when the impairment is more concentrated or diluted on the fish (ecosystem).

Figures 3-9a and 3-9b, illustrate the temporal sequence type of evidence showing support and weakening the case.

Figures 3-1a through Figure 3-3b illustrate the concept of Spatial/Temporal Co-occurrence

This page shows how to derive and evaluate evidence of spatial/temporal co-occurrence.
