原文：

Leonardo da Vinci is well known for having used less conventional painting methods and substances in his work, and we're still making new discoveries about them – the latest being a mix of toxic pigments underlying the brushwork on the Mona Lisa.

Researchers from France and the UK looked at a tiny microsample taken from a hidden corner of the Mona Lisa, deploying a variety of X-ray diffraction and infrared spectroscopy imaging techniques to identify the substances used.

译文：

列奥纳多·达·芬奇（Leonardo da Vinci）以在作品中使用非传统绘画技巧和材料而闻名，而我们对他的画作仍不断有新发现——最新发现是画作《蒙娜丽莎》（Mona Lisa）的笔触下含有毒颜料混合物。

法国和英国研究者们从《蒙娜丽莎》不显眼的一角采集了微小样本进行研究，运用了各种X射线衍射和红外光谱成像技术来确定画作上使用的物质。
