1. Differentiation of Brain and Reproductive Organs in Birds : Effects of Environmental Contaminants
Sammanfattning : The first objective of this thesis was to investigate effects of endocrine disruptors on the developing brain and gonads of bird embryos. The substances studied were the insecticide methoxychlor, and nine UV-filters (3-benzylidene camphor (3BC), 4 methyl benzylidene camphor (4MBC), benzophenone (BP) 1,2 and 3, 4 hydroxy benzophenone (4 HB), 4 dihydroxy benzophenone (4DHB), benzyl salicylate (BS), and ethyl-4-aminobenzoate Et-PABA)), commonly used in cosmetic products.
