Toxicity of Water-Soluble Fractions of Petrol on Some Freshwater Microalgae
This study assessed the toxicity of water-soluble fractions of petrol on Chlorella vulgaris and Scenedesmus
obliquus. Water soluble fractions of petrol were prepared into various concentrations as follows: 0%, 5%, 10%, 25%, 50%, 75%
and 100%. These treatments were inoculated with 5 mL of the test microalgae and read at 750 nm at two-day intervals for 14
days using a UV/VIS Spectrophotometer.
