Nematode sediment contact test

Chemical pollutants vs. aquatic ecotoxicological tests vs. nematode sediment contact test... 

According to the evaluations of Elbe sediments by raw data of a) aquatic ecotoxicological tests, b) chemical measurements, and c) nematode sediment contact tests in Fig. 3, clustering results by means of all parameters simultaneously (i.e. over the whole property space) for each of the groups and additional partial ordering is shown in Fig. 7. A common characteristic for both chemical and ecotoxicological tests is, that... 

In contrast to the partial orders from chemical concentrations and aquatic ecotoxicological tests, the results of the sediment contact tests with nematodes lead to a total order. This corresponds to a correlation analysis that shows a significant correlation between growth, reproduction and egg hatch (r=0,7).
