Additional information

Experimental testing of adsorption/desorption behaviour of ferro niobium is technically not feasible since the test item concentration in aqueous phase cannot be measured with sufficient accuracy due to insolubility in water. This alloy is used mainly in the production of high-grade structural steel and superalloys. Based on its uses a direct and indirect entry into the environment is very unlikely to occur.
