紫外线照射下的相关有害化学物质

Relevant harmful chemicals under ultraviolet radiation

介绍的紫外线吸收剂只局限于二苯甲酮和苯并三唑2类,主要是减缓塑料制品因光照而发生的老化,而且都是致癌、致诱变、致生殖毒性物质(CMR)。紫外线屏蔽剂适用于纺织品涂层整理,为无机化合物,对人类和环境无害。简单介绍了纳米材料及其内涵。受媒体启发,探讨了防晒霜的危害,三氯生受紫外线照射产生CMR的机理,以及紫外防护的误区。

Ultraviolet absorbents introduced are limited to two types including benzophenone and benzotriazole.They mainly slow down the aging of plastic products caused by light,and are of carcinogenic,mutagenic and reproductive toxic substances(CMR).Ultraviolet shielding agent is suitable for textile coating finishing.It is inorganic compound and harmless to human and environment.And the nanomaterials and their connotations are briefly introduced.Inspired by the media,the harm of sunscreen and the mechanism of CMR produced by triclosan irradiated by ultraviolet were discussed,which we should be aware of.
