干扰

Environmental hormone means endocrine disrupter substance, is definition by Japan Environmental Administration in 1997. This substance once enter in vivo by way of environmental conveyance, will amiss bonding with the receptor. It will result influence like hormone or destroy the balance and function of normal endocrine system.

摘要 环境荷尔蒙由日本环境厅在1997年所定义，指的是外因性内分泌干扰物质，此等物质一但经由环境介质进入动物体内后，会和体内的受体发生错误结合，产生类似荷尔蒙的影响或是破坏干扰原有内分泌系统的平衡及功能，进而干扰动物体内的生理作用。
