The density, API and flash point of the bitumen used in this study at 15oC was 0.9898 g/cm3, API at 60oF value of 11.46 and >200oC respectively. The total TPH and PAH constituent of the bitumen was 20,549.77 mg/l and 924.09 mg/l respectively. Analysis of the effect of different concentrations (10mg/L, 20 mg/L, 30 mg/L, 40 mg/L and 50 mg/L) of bitumen on T. guineensis revealed that the mortality of the organism increased as the concentration of the toxicant and time of exposure increased. The concentration with the longest exposure time where lowest mortality was observed was 40mg/l for 24 hours. The probit analysis on the lethal concentration (LC10, LC20 and LC50) of the toxicant on T. guineensis when exposed for 96 hours revealed a varying mortality status. The LC10, LC20 and LC50 of the bitumen on the T. guineensis was 6.746 mg/L, 10.773 mg/L and 26.38 mg/L respectively. Continuous discharge of untreated wastes especially petroleum-based products should be discouraged as it poses serious threat to aquatic habitat and produces.
