[ 5 ] [ 7 ] In 2020, the United States Environmental Protection Agency stated that "tetrachloroethylene exposure may harm the nervous system, liver, kidneys, and reproductive system, and may be harmful to unborn children", and reported that ...
The plant is toxic enough to cause human and animal fatalities if ingested. Every part of the plant is poisonous, especially the tuberous rhizomes. As with other members of the Colchicaceae, this plant contains high levels of colchicine, a toxic alkaloid. It also contains the alkaloid gloriocine.

These plants are extremely toxic. Spotted Water Hemlock is internally poisonous (ingesting can be fatal), and giant hogweed is both internally and externally poisonous.
1,1,2,2,-Tetrachloroethane (TeCA) can be rapidly and extensively absorbed from oral and inhalation exposure. In animal studies the oral take up was reported as 70-100% [15] [16] and 40-97% oral uptake in human inhalation. [17] [18] TeCA is a small, volatile, lipophilic molecule; TeCA can be readily absorbed from respiratory and gastrointestinal ...
“This is detrimental for insects, birds, and other animals that rely on native plants.” Invasive plants also spread quickly in multiple ways, such as by seeds, creeping stems and roots, or ...
Investigation by the Taiwan Environmental Protection Administration confirmed that RCA had been dumping chlorinated organic solvents into a secret well and caused contamination to the soil and groundwater surrounding the plant site.
