Plastic 'feminizes boys'

研究:塑料使男孩女性化

Chemicals in plastic alter the brains of baby boys, making them "more feminine," say researchers from the University of Rochester, the US, BBC reported. They found boys exposed to high doses of chemicals called phthalates while in the womb were less likely to play with boys' toys like cars or to join in rough and tumble games. Phthalates are widely used in household plastic items.

據(jù)英國廣播公司報道，美國羅切斯特大學(xué)的研究者表示，塑料制品所含化學(xué)物質(zhì)鄰苯二甲酸鹽會對胎兒腦部發(fā)育產(chǎn)生影響，致使男孩"女性化"。研究發(fā)現(xiàn)，如果孕婦體內(nèi)的鄰苯二甲酸鹽濃度較高，產(chǎn)下的男嬰喜歡汽車之類的男孩玩具和打斗游戲的可能性較小。據(jù)了解，鄰苯二甲酸鹽被廣泛用于制造日常塑料品。
