Effects of Anionic Surfactant Ingredients on Hematological Index of the Brown Trout (Salmo trutta fario)

Abstract

The aim of this study was to determine the toxicity of sodium dodecyl sulfate (SDS) to aquatic organisms. The effects of SDS were investigated using the hematological index of the brown trout (Salmo trutta fario). Fish were exposed to control (0 mg/l), low dose (1.5 mg/l) and high dose (2.25 mg/l) of SDS over a 21-day period. At the end of the treatment period, the control and the treatment groups were investigated for the hematological index [total erythrocyte count (RBC), total leukocyte count (WBC), hemoglobin (Hb), hematocrit (Hct), total platelet count (PLT), erythrocyte sedimentation rate (ESR), mean cell hemoglobin concentration (MCHC), mean cell hemoglobin (MCH), and mean cell volume (MCV)]. The results showed a significant increase in RBC, WBC, PLT, Hb, ESR, MCV, MCH, and MCHC values of the group exposed to high SDS concentrations compared to those in the low-dose treatment and control (p
