Long-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
There are no long-term aquatic invertebrate toxicity studies for the reaction product Marlon ARL. Assessment reports for the two read across substances that comprise the substance being registered (the reaction product Marlon ARL) indicate that these read across substances (i.e., LAS and hydrotropes) do not pose a risk to the aquatic environment for all relevant uses. In Annex IX of Regulation (EC) No 1907/2006, it is laid down that chronic toxicity tests shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on fish. Therefore a long-term toxicity study in aquatic invertebrates is not recommended.
Key value for chemical safety assessment
Fresh water invertebrates

Additional information
There are 5 study reports of long-term toxicity to aquatic invertebrates for the substance that is the main consituent of the reaction product Marlon ARL. That read across substance is linear alkylbenzenesulfonate (LAS) and the data are: 21-day EC50 is 1.5 and NOEC is 1.18 mg/L for daphnids; 7-day LC50 is 5.34 and NOEC is 0.5 mg/L for ceriodaphnids; 28-day NOEC is 2.8 mg/L for midge; 2-day EC50 is 2.0 and EC10 is 1.18 mg/L for rotifer; and 32-day EC20 is 0.27 mg/L for clam, 24-day EC20 is 0.95 mg/L for amphipod, and 32-day EC20 is 2.9 mg/L for snail.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
