Copper oxychloride |
Last updated: 31/10/2024 |
(Also known as: dicopper chloride trihydroxide) |
SUMMARY |
A widely used copper fungicide. It has a low aqueous solubility and a low volatility. As a heavy metal, copper itself will not degrade in the environment. It is moderately toxic to mammals and most biodiversity |
Data alerts |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
