Histopathological effects of water soluble?fraction of crude oil on liver tissue of fingerling beluga , Huso huso Linnaeus, 1754
In this study the LC50 96h values of water-soluble fractions (WSF) of the Caspian Sea ? exploited crude oil were determined in beluga, Huso huso fingerlings. The fingerlings averaged 2.42 ? 0.11 g in weight were exposed to WSF crude oil at concentrations 24.75, 27, 29.25, 31.5, 33.75, 36, 38.25 ppm. The treatments were performed in three replicates and all changes in the specimens were determin...
متن کاملBioassay using the water soluble fraction of a Nigerian light crude oil on Clarias gariepinus fingerlings.
A 96-hour bioassay was conducted using the water soluble fraction of a Nigerian light crude oil sample on Clarias gariepinus fingerlings. 0, 2.5, 5.0, 7.5 and 10 mls of water soluble fractions (WSF) of the oil were added to 1000 litres of de-chlorinated tap water to form 0, 25, 50 , 75 and 100 parts per million representing treatments 1 to 5 respectively. Each treatment had two replicates with ...

متن کاملPathological alterations in response to water soluble fraction of Iranian crude oil in gill of yellow fin sea bream Acanthopagrus latus (Houttuyn, 1782)
Water soluble fraction (WSF) of crude oil can pollute water and cause histopathological alterations in fishes. Therefore, sea water pollution with crude oil could detrimentally impact the fish health. The aim of the present study was to evaluate the effect of different concentrations of WSF on gills of yellow fin sea bream. The fish were exposed to 0% (control), 2%, 4%, 8% and 16% of WSF for a ...
متن کاملImpact of US Energy Policy on Crude Oil Prices
The price of Iranian crude oil in different markets depends on the price of US crude oil. In recent months, the oil and gas industry and the sale of Iranian crude oil and the co-operation and investments of oil companies operating in the field of oil field development have halted. Therefore, examining the effects of US government policies on the oil market is very effective. The most important ...
