 Details on sampling:
 The limit test item concentration and the controls were confirmed by analytical verification via LCMS/MS on day 2 from the freshly spiked artificial sediment and on day 0, 7 and 28 using additional replicates, each. Determination of the test item was performed for the sediment, pore water and the overlying water in the controls and limit test item concentration under GLP. Except for the samples of day 2 and 0 all replicates contained worms. The method was implemented under nonGLP and documented finally in the GLP raw data.
 Vehicle:
 yes
 Remarks:
 Acetone
 Details on sediment and application:
 Sediment
Artificial sediment containing:
 4 % peat, airdried and finely ground
 20 % kaolin, with a kaolinite content > 30 %
 76 % quartz sand (> 50 % particles sized 50200 µm)
 0.2 % calcium carbonate (CaCO3) to achieve a pH of 6.92
The organic carbon content of the final mixture was 2.35 % (external determination, nonGLP).
Application
The respective test item amount was weighed out for the limit test item concentration and dissolved in acetone.
The appropriate amount of spiking solution (2.5 mL per replicate) was thoroughly mixed with a subquantity of the artificial sediment (10 g per replicate). After complete evaporation of the solvent, the spiked portion of artificial sediment was thoroughly mixed
with the remaining sediment. Demineralised water was added to the artificial sediment to adjust the humidity of the artificial sediment to a moisture of 30 %.
Subsequently, the test medium was thoroughly mixed to ensure a homogenous distribution and about 45 g soil dry weight were filled into the test vessels.

Summary
The effects of the test item FATTY ACIDS, C18 UNSAT, REACTION PRODUCTS WITH DIETHYLENETRIAMINE, Batch number 1865159) on the endobenthic oligochaete Lumbriculus variegatus in a watersediment system were determined at the test facility in Sarstedt, Germany, from 20200831 to 20201009, with the definitive exposure phase from 20200902 to 20200930. The study was carried out according to OECD Guideline 225 (2007). The test duration was 28 days from the insertion of the test organisms. The study was performed by spiking artificial sediment with the limit test item concentration 1000 mg/kg sediment dry weight. A control using untreated artificial sediment as well as a solvent control using artificial soil treated with the solvent were set up. Six replicates per control and limit test item concentration were set up for biological investigations. Water quality parameters (temperature, pHvalue, O2concentration, ammonium and total hardness) were determined throughout the study using an additional replicate for the controls and the test item concentration, each.
Analytical evaluation of the test item FATTY ACIDS, C18 UNSAT, REACTION PRODUCTS WITH DIETHYLENETRIAMINE and controls was carried out via LCMS/MS on day 2 from the freshly spiked artificial sediment and on day 0, 7 and 28 using additional replicates, each.
The measured concentration of the freshly spiked artificial sediment on day 2 was 117 %, thus indicating its proper preparation. The control samples were < LOQ. After 7 and 28 days 87 and 47% were recovered respectively.
The pore water concentration in these samples remained relatively constant
After 28 days of exposure, FATTY ACIDS, C18 UNSAT, REACTION PRODUCTS WITH DIETHYLENETRIAMINE induced no mortality in the limit test item concentration 1000 mg/kg sediment dry weight.
The total number of worms and thus the reproduction as well as the total biomass per replicate did not statistically significantly differ compared to pooled control in the limit test item concentration.
All validity criteria were fulfilled.

Description of key information
There is one long term sediment test with lumbriculus variegatus available which was performed according to OECD 225 under GLP conditions and fulfilled all validity criteria.
The test was performed as limit test at 1000 mg a.i./kg dw and no effects were observed.
In addition to measured data the PNECsed was calculated using the equilibrium partitioning method (EPM).
Key value for chemical safety assessment
 EC10, LC10 or NOEC for freshwater sediment:
 1 000 mg/kg sediment dw
Additional information
The effects of Fatty acids, C18 unsat, reaction products with diethylenetriamine (AAIDETA) on the endobenthic oligochaete Lumbriculus variegatus in a watersediment system were determined under GLP conditions. The study was formed according to OECD Guideline 225 (2007). The test duration was 28 days from the insertion of the test organisms. The study was performed by spiking artificial sediment with the limit test item concentration 1000 mg/kg sediment dry weight. A control using untreated artificial sediment as well as a solvent control using artificial sediment treated with the solvent were set up. Six replicates per control and limit test item concentration were set up for biological investigations. Water quality parameters (temperature, pHvalue, O_{2}concentration, ammonium and total hardness) were determined throughout the study using an additional replicate for the controls and the test item concentration, each.
Analytical evaluation of the test item Fatty acids, C18 unsat, reaction products with diethylenetriamine and controls was carried out via LCMS/MS on day 2 from the freshly spiked artificial sediment and on day 0, 7 and 28 using additional replicates, each. The measured concentration of the freshly spiked artificial sediment on day 2 was 117 %, thus indicating its proper preparation. The control samples were < LOQ.
After 28 days of exposure, Fatty acids, C18 unsat, reaction products with diethylenetriamine induced no mortality in the limit test item concentration 1000 mg/kg sediment dry weight.
The total number of worms and thus the reproduction as well as the total biomass per replicate did not statistically significantly differ compared to pooled control in the limit test item concentration. For further endpoints, please see Table 1 below.
All validity criteria were fulfilled.
Table 1: Summary of all Effects, Based on Nominal Test Item Concentration
Effects 
Fatty acids, C18 unsat, reaction products with diethylenetriamine 
 [mg/kg sediment dry weight] 
LOEC (Total number of worms/Reproduction, Biomass)  > 1000 
NOEC (Total number of worms/Reproduction, Biomass)  ≥ 1000 
The PNECsed of 10 mg/kg dw is according to REACH guidance R.10 calculated from the available longterm lumbriculus test by applying the default safety factor of 100.
In the absence of any measured toxicity to sediment organisms the PNECsed can also be calculated using the Equilibrium Partitioning Method (EPM). Because of the availability of a longterm sediment test for a substance for which it is indicated that the use of EPM to predict the PNECsediment is not appropriate (surfactant, ionic). The PNECsed of 10 mg/kg dw will be used for risk assessment.
For comparison reasons the PNECsed was also calculated using the Equilibrium partitioning method (EPM). According to REACH guidance R.10 this method uses the PNEC_{aquatic }and the sediment/water partitioning coefficient as inputs.
The dose response results for the algae test are calculated based on nominal Test Loadings. The PNECaquatic is based on the Algae E_{r}L_{10} after 72 hours is 20.7 µg/L. The EL10 for daphnia was observed to be 133 µg/L.
The PNEC_{sed }is then calculated using the equations detailed in the TGD:
PNEC_{sed} = K_{suspwater}* PNEC_{aquatic }* 1000 * 1 / RHO_{susp}
Where: PNEC_{aquatic } = 2.07 µg/L
K_{suspwater} = 23500.9 m^{3}.m^{3}
RHO_{susp} = 1150 kg.m^{3}(TGD, equ. 18)
PNEC_{sedEPM} = 42.3 mg/kg ww = 194.6 mg/kg dw
Applying the additional safety factor for exposure via ingestion: 10
PNEC_{sedEPM} = 4.23 mg/kg ww
= 19.46 mg/kg dw
