Reliability: 4 This study was given a reliability score of 4 because the original reports
reviewed by the authors were not directly reviewed in the compilation of this
robust summary.

Species: Crustacean species
Results: LC50 = 17.0 mg/L (14 records; SD = 0.68)
Test Substance: LAS; all in the alkyl chain length C10-14
Remarks: LC50 is geometric mean of 14 records compiled from literature reviews.
Geometric mean LC50 for all taxa (36 records) was 4.36 mg/L.
