چکیده

laboratory-scale experiments were conducted to evaluate the joint action toxicity and biochemicaleffects of sublethal concentrations of forcados light crude oil (flco) and three dispersants against clariasgariepinus over a period of 28 days. the derived 96hrlc50 values revealed that the dispersant, ds/tt/066(0.03ml/l) was the most toxic, followed by dispersant, oc/tt/osi (0.19ml/l), flco (5.06ml/l) andcrystal clear oil dispersant (ccod = 12.06ml/l) the least toxic when acting singly. joint action toxicityevaluations of flco and dispersants showed that the interaction between flco : ds/tt/066 and flco :oc/tt/osi was synergistic (synergistic ratio (sr) > 1) with sr values of 10.5 and 3 respectively. however,for the mixture of flco : ccod, the interaction was antagonistic (sr < 1) with sr value of 0.97. the resultof the biochemical effects study revealed that malondialdehyde (mda) levels decreased significantly (p

Bioassay 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 ...

Short and long term toxicity of crude oil and oil dispersants to two representative coral species.

Oil dispersants, the tool of choice for treating oil spills in tropical marine environments, is potentially harmful to marine life, including reef corals. In a previous study, we found that dispersed oil and oil dispersants are harmful to soft and hard coral species at early life stages. In this broader study, we employed a "nubbin assay" on more than 10 000 coral fragments to evaluate the shor...

Changes in rat liver enzyme activities following consumption of crude oil contaminated catfish (Clarias gariepinus)

Objective: To study changes in selected liver enzymes of albino rats fed on diet formulated with catfish that were exposed for 30 days to water polluted with crude oil. Methodology and results: One hundred and twenty (120) catfish (Clarias gariepinus) in six groups of 20 catfish each were held for 30 h in water having five different concentrations of crude oil (0.1, 0.25, 0.5, 0.75 and 1% v/v)....
