Migrates from plastic food packaging were tested for oestrogen activity by yeast oestrogen screen and subsequently analysed by chromatographic methods to identify oestrogen-active chemicals. Oestrogenic activity ranging from 0.7 to 59 ng/l 17β-estradiol equivalents was detected in seven out of 42 samples tested. A number of chemicals with known or supposed oestrogen activity were identified in migrates of oestrogen-active samples.
