威尼斯运河河水变绿的原因找到了

Italian authorities finally discover why Venice's Grand Canal turned fluorescent green

The Grand Canal in Venice turned fluorescent green on 28 May, sparking debate as to the cause of the colour change. Now authorities have said that the chemical fluorescein, used to find leaks during underwater construction, was responsible. Despite being non-toxic, it remains uncertain how such a large quantity of the substance ended up in the canal. Although police are investigating a number of potential leads, including environmental activism, no group has claimed responsibility for the incident.

威尼斯的大运河在6月13日变成了荧光绿色，引发了对其颜色变化原因的讨论。现在当局表示，用于水下建设中帮助辨识渗漏的荧光素是造成这一现象的原因。尽管荧光素是无毒的，但仍不确定这么大量的物质是怎么进入河道之中的。尽管警方正在调查一些潜在的线索，包括环保主义的可能性，但没有团体宣称对此事件负责。
