A multispecies test was performed together with seven species tests, one for each type of aquatic animal. Results for four other aquatic invertebrates : 96 -h LC50 values: Duesia tigrina (Flatworm): LC50 = 5.9 mg/l Helisoma trivolvis (Snail): LC50 = 32 mg/l Gammarus fasciatus (Sideswimmer): LC50 = 3.2 mg/l Asellus intermedius (Pillbug): LC50 = 17 mg/l
