| Abstract |
The effect of the synthetic pyrethroid flucythrinate on three non-target invertebrates was evaluated using continual and short-time exposure methods. Both methods show toxic action at measured concentrations 0.100 micrograms/litre. The use of both approaches pointed toward the importance of exposure time in hazard assessment. Exposures for a short time followed by an extended observation period in insecticide-free water show that a lethal exposure can occur in less time than estimated from continually exposed animals. For example, continually exposed Gammarus lacustris had a 72 h LC50 of 0.12 micrograms/litre. However, exposure for only 17.6 h at 0.12 micrograms/litre will kill 50% of the exposed animals during an extended observation time. The use of both approaches can also provide insights into minimum exposure times for each test concentration, and the possibility of post-exposure mortality. |
