文摘
- •
Elodea canadensis was used as indicator in sediment contact test.
- •
Chromosomal abnormalities in anaphase–telophase cells of roots were analyzed.
- •
Genotoxicity endpoint of E. canadensis is sensitive to the quality of sediments.
- •
The spectra of abnormalities in roots in situ and in laboratory tests were similar.
- •
The percentage of abnormal cells was higher in laboratory tests than in situ.
