Last updated: 15/01/2023
(Also known as: NP-48)
Alloxydim sodium is a herbicide. It is highly soluble in water but little other environmentally relevant information is available. Little is known about its human toxicology.
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.
