Additional information

There are no data describing the long-term toxicity of the registered substance to soil macroorganisms.

Terrestrial toxicity testing with D4 in response to ECHA decision number TPE-D-2114422498-44-01/F has been delayed due to difficulties in obtaining radiolabelled test material. A preliminary stability study under OECD TG 222 conditions has been carried out using the structurally related substance L4 and demonstrates significant losses due to volatilisation over a five-week period (37% remaining radioactivity after 35 days). Based on the air-soil partition coefficient, D4 is expected to be less stable in soil, therefore a preliminary stability study under OECD TG 222 conditions is in progress with D4 to determine feasibility of terrestrial testing.
