Description

Eggs of the common frog are exposed to well-known thyroid disrupting compounds throughout tadpole development, and the chemicals have already been tested in Xenopus (LAGDA/AMA). The exposure duration is approx 6 weeks and the eggs are collected in nature. The exposure setup is a flow through system and the actual chemical concentrations are determined by LC-MSMS. The endpoints are thyroid gland and eye histology, biometric measurements (e.g. hind limb length), developmental stage and thyroid hormone levels, and the data are compared with already published data on Xenopus.
