OECD GD 29: Transformation / Dissolution of Metals and Metal Compounds in Aqueous Media

The Transformation/Dissolution Test acc. to OECD GD 29, is a standardized method designed to evaluate how metals and sparingly soluble metal compounds behave in water. The purpose of the study is to understand the rate and extent to which these substances produce soluble available ionic and other metal-bearing species in aqueous media under a set of standard laboratory conditions.

We offer two options:

• Short term test: 7 days; 1, 10 and 100 mg/L nominal load; pH range 6.0 – 8.5
• Long term test: 28 days; 1 mg/L nominal load; pH range 5.5 – 8.5
• Or any combination on request

For the analytical determination we have a new state-of-the-art ICP-OES and ICP-MS available.

The results help to evaluate the aquatic toxicity of the metal compounds from which the soluble species originate. They can be used for REACH registrations and any other regulatory purpose where behavior in water is required. We offer the study under GLP conditions. LAUS has performed this study for more than 10 years and our experts have a lot of experience with the performance of this study.
