Ebke K.-P. et al., Evaluation of Direct and Indirect Effects of an Insecticide on Aquatic Organisms in Outdoor Ponds; Registration report; 2002:

An outdoor experimental mesocosm study with an Insecticide was performed. The purpose of this study was to investigate the acute and chronic effects of the test item in 22 outdoor mesocosms (1070 L), focusing on effects on biological parameters under field conditions in naturalised pond water. The effects to be monitored at the ecosystem level include

•  functional parameters (conductivity, pH-value, dissolved oxygen and total carbonate).
• diversity of species.

 The population effects to be monitored include

• abundance of populations of phytoplankton, periphyton, zooplankton, macrozoobenthos, and insect emergences (EC50; NOEC, EAC)

• recovery time of sensitive organisms

• indirect population effects.

Ebke K.-P. et al., Evaluation of Direct and Indirect Effects on Fish and Bioconcentration in Aquatic Organisms of 14C-labelled Herbicide in Outdoor Pond Mesocosms; Registration report; 2001:

The objective was to investigate the potential bioconcentration of a herbicide under simulated field conditions in outdoor pond mesocosms and to investigate the possible effects of water-borne and oral exposure, including biomagnification through the aquatic food chain, on fish.
The potential bioaccumulation effects monitored within the study include:

• Concentration of radioactivity in macrozoobenthos (e.g., Baetidae),   phytoplankton, periphyton and zooplankton (e.g., Daphniidae).
• Concentration of radioactivity in fish.
• Effects on fish (survival, behaviour, growth rate). 
• Concentration of radioactivity in water and sediment.
• Radiochemical recovery of applied radioactivity.
