Abstract/Summary
Experimental exposure of Tilapia nilotica to Arsenic (V) was done using a continuously aerated static bioassay system. The silverdiethyldithiocarbamate (AgDDC) method of arsenic analysis was utilized to determine arsenic concentrations from the samples. Probit analysis for the estimation of the acute toxicity showed the 96h LC50 to be at 79 mg/l. Estimates of the rate (delta-conc/delta-time) and percent values of total As(V) bioaccumulation and bioelimination revealed an oscillating pattern over the 96h period of exposure. Such pattern showed that As(V) can be bioaccumulated within a short period of time (0.5h). Likewise, the pattern also showed that Arsenic(V) was bioeliminated once the contaminated organism (Tilapia nilotica) was placed in arsenic-free medium.
