Effects of chronic application of the fungicide Derosal(R) (active ingredient carbendazim) were studied in indoor macrophyte-dominated freshwater microcosms. The concentrations (0, 3.3, 33, 100, 330 and 1000 µg/l) were kept at a constant level for 4 weeks. This paper is the second of a series of
To assess potential aquatic pesticide risks, environmental monitoring strategies often focus on water and sediment. However, knowledge gaps with regard to the pollution status of organic matrices important for the structure and functioning of aquatic ecosystems do exist. The present study assessed
Floodplain lakes in the Rhine-Meuse delta of the Netherlands vary considerably in levels of sediment-bound toxicants. Microcosm experiments were done to compare the ecological impact of the fungicide triphenyltin acetate (TPT) between test systems with clean or polluted sediments (10 microcosms
The fungicide fluazinam, the insecticide lambda-cyhalothrin, and the herbicides asulam and metamitron were applied to indoor freshwater microcosms (water volume approximately 0.6 m3). The treatment regime was based on a realistic application scenario in tulip cultivation. Concentrations of each
