Based on the need for a standardized test design to test the effect of veterinary medicinal products on plants in a more realistic way, the following objectives of this research project arise: Development of a test design for a modified OECD 208 seedling emergence and growth plant test with a more realistic exposure in manured soil; Experimental verification of the practicability of the test design by means of two veterinary antibiotics and two kinds of manures (pig and cattle) in tests with six plant species; Preparation of a manual for the performance, evaluation and reporting of extended plant tests with an exposure scenario via manure application for the use in environmental risk assessment of veterinary medicinal products.<BR>Quelle: https://www.umweltbundesamt.de
