Aramite (Ref: ENT16519)
Last updated: 04/03/2022
(Also known as: aratron; niagaramite; compound 88R ; 88-R)
SUMMARY
Aramite is an obsolete miticide and antimicrobial agent. It has a low aqueous solubility and a low volatility. It may be persistent in soil systems depending upon local conditions. Aramite is not expected to leach to groundwater based on its physico-chemical properties. It is moderately toxic to fish. highly toxic to aquatic invertebrates. It has a low oral mammalian toxicity but may be carcinogenic. It is a recognised irritant.
