Mecoprop-P n-octyl ester hydrolyses rapidly in natural water. Therefore, the estimated BCF of 487.6 L/kg is only of theoretical interest. The hydrolysis product Mecoprop-P acid (MCPP-P acid) with a BCF up to 5.5 and an elimination half-life of 27.4 h for the whole fish showed no potential for bioaccumulation.
