Bioaccumulation and Metabolism of Pyriprox-yfen in Tadpoles of Xenopus laevis
Amphibian is one of the typically higher aquatic organisms, while its bioaccumulative potential of pesticides is usually assessed by using fish data as surrogate obtained through a guideline study. However, not only the various differences in physiology, life cycle and morphology between them but also the possibly dermal uptake of pesticides in amphibian may raise some concern on the validity of such an approach. Moreover, research on amphibian is in the forefront of assessing endocrine disrupting potential of chemicals, as represented by its metamorphosis assay. Nevertheless, there appears to be much lesser knowledge on bioaccumulation of pesticides in amphibian than fish in relation to distribution, metabolism and excretion, which greatly support more detailed risk assessment of pesticides.
