"新衣服不洗就穿会致癌！"最近换季期间，李女士网购了大量新衣，其中不少是价格低廉的外贸尾单。当她拆快递时，母亲严肃警告她必须先清洗再穿。"Brand new clothes without washing may cause cancer!" During the recent seasonal change, Ms. Li purchased many new clothes online, including budget-priced overstock items. When unpacking, her mother sternly warned they must be washed first.
一、新衣服直接穿会致癌吗？ | Part 1: Does Wearing New Clothes Directly Cause Cancer?
新衣服确实含有甲醛，因为在染色、定型等工序中会使用含甲醛的化学制剂。世界卫生组织将甲醛列为1类致癌物。New clothes do contain formaldehyde as it's used in dyeing and shaping processes. WHO classifies formaldehyde as Group 1 carcinogen.
但国家纺织品质检中心专家表示，合格服装的甲醛释放量（0.012-0.426ppm）远低于致癌浓度（>1.0ppm）。However, experts note formaldehyde emission from qualified clothing (0.012-0.426ppm) is much lower than carcinogenic level (>1.0ppm).
