Abstract
Effects of imported (I) and synthetic (S) metal working fluids and different concentrations formed from these fluids with each of benzyl triethyl ammonium chloride (A), benzyl triethanol ammonium chloride (B), P-methyl benzyl triethyl ammonium chloride (C) and P-methyl benzyl triethanol ammonium chloride (D) in different concentrations were studied on growth and structure of green alga Scendesmus obliquus. The toxicity of surfactants to Scendesmus obliquus are arranged in the order: imported fluid > Synthetic fluid > S+D > I+A > S+B > I+C > I+B > I+D > I+D > S+A > I+4. These results prove that the toxicity of fluids depends on its chemical structure.
