Guidance Document on Simulated Freshwater Lentic Field Tests (Outdoor Microcosms and Mesocosms)

Outdoor microcosms and mesocosms are useful in risk assessment when lower-tier and higher-tier laboratory studies (single-species and multi-species) indicate potential risks. They can be an important tool in bridging the gap between these studies and attempts to understand, predict and confirm what may occur in the natural environment subject to...
