Table 7 Pros and cons for wet and dry spiking
From: Influence of application techniques on the ecotoxicological effects of nanomaterials in soil
| Â | Dry spiking | Wet spiking |
|---|---|---|
Pros | · High concentrations independent of test material | · Higher bioavailability at least at lower test concentrations |
· Procedure independent of test concentration | ||
Cons | · Reduced bioavailability | · Functionalization of surface by stirring / sonication |
· Test concentrations comparably low (limitation: WHCmax, sedimentation of nanomaterials in stock dispersion) | ||
· Agglomeration at higher concentrations of stock suspension can limit bioavailability; behavior differs according to material |
