Enzymatic hydrolysis products of Laminaria japonica, S. japonica, Laminariaceae

Adsorption / desorption

Administrative data

Endpoint:

adsorption / desorption: screening

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption

Justification for type of information:

In general, fate and environmental data requirements do not need to be fulfilled because algae and algal products, used as soil amendment, are readily transformed in elements naturally present in the environment. Furthermore, seaweed extracts are included in Annex I of Directive 91/414/EEC, which requires a reduced package of studies for Plant Protection Products made from plants or plants extracts (SANCO Draft Working Document 10472/2003/rev. 5).
