Pyrethroid insecticides are commonly used in pest control and are present at toxic
concentrations in surface waters of agricultural and urban areas worldwide. Monitoring is …

Abstract Standard US Environmental Protection Agency laboratory tests are used to monitor
water column toxicity in US surface waters. The water flea Ceriodaphnia dubia is among the …

Use of pyrethroid pesticides, which are highly toxic to aquatic organisms, has increased
substantially over the past decade. In 2006, the pyrethroid pesticides cyfluthrin and …

Over the past 5 years numerous toxicity studies in California using the amphipod, Hyalella
azteca, have reported that pyrethroid insecticides, and less frequently the organophosphate …

A series of acute toxicity tests with the amphipod Hyalella azteca was performed to quantify
the synergistic effect of piperonyl butoxide (PBO) on pyrethrin toxicity. Concentrations of …

The aquatic toxicity profiles of synthetic pyrethroid insecticides are remarkably similar, and
results for a large number of species can be combined across compounds in Species …

Laboratory toxicity testing is the primary tool used for surface water environmental risk
assessment; however, there are critical information gaps regarding the sublethal effects of …

Current ecotoxicological research on particle-associated pyrethroids in freshwater systems
focuses almost exclusively on sediment-exposure scenarios and sediment-dwelling …

Pyrethroid insecticides are known to be highly toxic to most aquatic nontarget organisms, but
little is known about the mechanisms causing some species to be highly sensitive while …

Pyrethroids are one of the most heavily used insecticide classes globally because they have
low mammalian toxicity. However, they are highly toxic to arthropods. Pyrethroids are …
