DESCRIPTION:Dr Inge WERNER\; EAWAG-Centre for Ecotoxicology\nPyrethroid in
 secticides are widely used in agriculture and residential pest control. In
  recent years\, they have been identified as pollutants in water and sedim
 ents of surface water bodies in California and elsewhere. Measurement of t
 hese hydrophobic and relatively short-lived\, but highly toxic chemicals c
 an present considerable challenges with respect to adsorption to sampling 
 equipment\, and degradation during sample storage\, while analytical detec
 tion limits in water samples (1-3 ng/l) are in the range of biological eff
 ect concentrations for sensitive aquatic invertebrates. Measured surface w
 ater concentrations are in a range where ecological fitness of fish may be
  impaired indirectly by the depletion of invertebrate prey\, and directly 
 by sublethal toxic effects on behavior or immune responses. This presentat
 ion will provide an overview of known toxic effect levels of pyrethroids i
 n aquatic species\, as well as information on their sublethal effects in f
 ish.
