文摘
- •
The Magdalena River has high levels of some metals such as Cd, Cu, and Ni.
- •
Most sediment extracts affected lethality, growth, and locomotion of C. elegans.
- •
Sediment extracts induced expression changes in mtl-2, sod-4, and gst-1.
- •
Sediment toxicity was primarily associated with Cd and Pb.
- •
Highest toxicity was observed for samples collected in mining and industrial areas.
