Additional information

Results of chronic toxicity studies carried out with three species of sediment-dwelling organisms are available:

• A prolonged toxicity study with Chironomus riparius using spiked sediment (Wildlife International Project 583A-104), performed in April/May 2005.

• A prolonged toxicity study with Lumbriculus variegatus using spiked sediment (Wildlife International Project 583A-106), performed in June/July 2005

• A prolonged toxicity study with Hyalella azteca using spiked sediment (Wildlife International Project 583A-103), performed in November/December 2005

The studies were carried out using procedures that are considered to be current best practice and have been assigned reliability 1.
