چکیده:

Crude oil is a very complicated composition that contains thousands of hydrocarbons. This study measured LC50 crude oil in water samples with different chemical andphysical characteristics. Crude oil concentrations 5, 10, 20, 30, 40, 50, 75 and 100 mg / l and water samples that each contains ten Daphnia were used. The numbers of liveDaphnia were counted 4, 24 and 48 hours after adding different crude oil concentration. The results showed that water with low turbidity and TDS that pollutedwith crude oil can cause more acute toxic effects on Daphnia and Physical andChemical Characteristics of Water can effected in crude oil toxicity in water.
