Zebrafish larvae were co-exposed to BDE-209 and Pb, major e-waste contaminants.
Their transcriptional profiles and phenotypic endpoints were examined 6 dpf.
The steroidogenic pathway and vitellogenesis were stimulated by BDE-209.
Pb exposure caused cardiac dysfunction and affected neuroendocrine regulation.
Co-exposure led to synergistic and antagonistic effects on gene transcriptions.
