Accumulation and excretion of chloroanilines by carp

Accumulation and excretion of chloroanilines were studied for carp ( L.). The average bioconcentration factors (BCF) in the whole body of the fish after 24 – 336 hr exposure were 2.0 and 3.7 for o-chloroaniline. 0.8 and 2.2 for m-chloroaniline and 0.8 and 1.7 for p-chloroaniline at high and low concentrations of the chemicals, respectively. The excretion rate constants (k) from the whole body of the fish were 0.19 hr⁻¹ for o-chloroaniline, 0.21 hr⁻¹ for m-chloroaniline and 0.16 hr⁻¹ for p-chloroaniline. The experimental data on the accumulation and excretion of the chloroanilines were consistent with the field data.
