Anthraquinone	Last updated: 12/06/2024
(Also known as: anthradione)

SUMMARY

Anthraquinone is a substance used as a bird repellent. It has a low aqueous solubility, volatile with a low risk of leaching to groundwater. it is non-persistent in soil but can be persistent in water under certain conditions. It shows a low mammalian toxicity but there are some concerns regarding its potential to bioaccumulate. No serious risks to human health have been reported. It is moderately toxic to birds, most aquatic organisms and earthworms. No data is available regarding the risk to honeybees.
