1 Environmental measurements of D4
The following is a summary of environmental monitoring data on D4, including studies with samples taken from 2004 to 2020. The monitoring results are summarised in the sections below:
1.1 D4 measurements in WWTP influent, effluent, sludge and air
1.2 D4 measurements in surface water
1.3 D4 measurements in air
1.4 D4 measurements in sediment
1.5 D4 measurements in biota
The studies include some remote locations, as well as locations close to urban populations.
Octamethylcyclotetrasiloxane (D4) is a cyclic volatile methyl siloxane (cVMS) that is present as an impurity in consumer products (e.g., personal care products). Cyclic VMS are highly volatile and of extremely low solubility in water. The main route of entry into the aquatic environment is via wastewater treatment plant effluents. Cyclic VMS do volatilise to air, but their properties dictate low potential for back-deposition to land or water.
Analytical measurement of trace levels of cVMS in environmental samples is difficult due to their physical properties and uses, which can inadvertently lead to significant background contamination. Cyclic VMS are used in personal care products including lotions, creams, deodorants, shampoos, insect repellents, and sunscreen (hereafter referred to generally as personal care products). Environmental samples can become compromised during all stages of field and laboratory work including sample collection, processing, extraction, and analysis. Since about 2008, environmental monitoring programs have incorporated the use of rigorous protocols strictly prohibiting the use of personal care products by all field and laboratory personnel involved, as well as avoiding equipment containing silicone-based materials. This has led to lower analytical backgrounds, reduced potential for contamination, and thus greater confidence in the environmental monitoring results.cVMS contamination may occur in the analytical process through impurities introduced during the sample preparation or the generation of cVMS from the stationary phase of widely used siloxane-based gas-chromatographiccolumns. With improvements in analytical technology allowing for lower method detection limits for cVMS, controlling for potential sources of contamination is even more critical, especially when attempting to measure concentrations of cVMS at the lower ppb-range.
1.1
Data on the presence of D4 in wastewater treatment plant (WWTP) influent, effluent, sludge and air collected above the WWTP are available from peer-reviewed literature (Table 1.1). Most of the studies reported used specific prohibition on use of personal care products by all field and laboratory personnel in order to reduce potential for contamination of the samples.
A recent study reported on the WWTP influent D4 concentrations to monitor the efficacy of the EU restriction of D4 in wash-off personal care products (ERM, 2020). During the initial period of the study (2017-2018), statistically significant differences in D4 concentrations were observed between some of the WWTPs, indicating that the selected WWTPs captured a good spread of conditions throughout the EU and the UK. Also, no statistically significant differences were observed in per capita mass loadings between days of the week (i.e., weekdays and weekend) and season. During the transitional period (2019-2020), differences in D4 concentrations were still observed. No statistically significant differences in the per capita mass loadings were observed between days of the week and season during this period. During the initial and the transitional periods, the estimated mass loadings of D4 (in t/y) were lower compared to the pre-restriction level as well as the post-restriction goals stated by ECHA.

1.3
Data on the presence of D4 in air are available from institutional reports and peer-reviewed literature (Table 1.3). Most of the studies reported on specific prohibition on use of personal care products by all field and laboratory personnel in order to reduce potential for contamination of the samples.
Samples were collected from urban areas, background areas as well as from remote areas. In recent years (2015-2017), D4 concentrations in air samples collected from urban areas in Europe (Spain and France) ranged between 33 and 696 ng/m3. These concentrations are generally higher compared to the air PEC at the Regional scale of 7.06 ng/m3(see Section 10.2.2); this could be due to high population density in these urban areas. D4 concentrations in air samples collected from other areas in Europe such as Scandinavia or Ireland were generally below 14 ng/m3. These concentrations are comparable to the air PEC at the continental scale estimated by EUSES 2.1.2 (2.56E-06 mg/m3or 2.56 ng/m3), which includes contributions from EU, EEA and UK sites.
D4 was monitored in air collected from remote areas, with the sampling site of Ny Alesund in Norwegian Arctic most reported on between 2011 and 2017. D4 was detected at concentrations generally in the range of 0.040 and 2.3 ng/m3. Concentrations reported in some of these studies were greater than the PEC for Arctic air estimated by EUSES 2.1.2 (1.39E-07 mg/m3or 0.139 ng/m3), which is likely due to the fact that there is a permanent population in Ny Alesund of approximately 150 people and it is also a popular stop for cruise ships.

Data on the presence of D4 in sediment are available from studies performed by Reconsile members, institutional reports and peer-reviewed literature (Table 1.4). Most of the studies reported on specific prohibition on use of personal care products by all field and laboratory personnel in order to reduce potential for contamination of the samples.
The presence of D4 in sediment has been monitored in freshwater system by Reconsile members and includes Lake Pepin, USA, Lake Ontario, Canada, Oslofjord, Norway and Tokyo Bay, Japan. In Lake Pepin, organic carbon normalized concentrations (ng/g OC) of D4 in the surface 0-3 cm of sediment, which represented about 1 year of sediment accumulation, were different between the five core sites (p=0.01) and between years (p<0.01), with significant year-core interactions detected (p<0.01). Organic carbon normalized concentrations of D4 in the surface 0-3 cm of sediment showed net changes ranging from –13% to +111% over the 5-year sample collection period, but significant temporal trends were not detected (p>0.27) except at TR-1 (p=0.02). In Lake Ontario, organic carbon normalized concentrations (ng/g OC) of D4 in the surface sediment (0-1 cm for Lake Ontario and 0-3 cm for Hamilton Harbor), which represented about 1 year of sediment accumulation, were different between the five core sites (p<0.01) and between years (p<0.01), with significant year-core interactions detected (p<0.01). Organic carbon normalized concentrations of D4 in the surface sediment showed net changes ranging from –29% to +42% over the 5-year sample collection period, but significant temporal trends were not detected (p>0.17). In the Oslofjord, organic carbon normalized concentrations (ng/g OC) of D4 in the surface 0-1 cm of sediment, which represented about 1 year of sediment accumulation, were different between the five core sites (p<0.01) and between years (p<0.01), with significant year-core interactions detected (p=0.01). Organic carbon normalized concentrations of D4 in the surface 0-1 cm of sediment showed net changes ranging from –27% to +133% over the 5-year sample collection period, but significant temporal trends were not detected (p>0.39) except at CS-4 (p=0.03). In Tokyo Bay, organic carbon normalized concentrations (ng/g OC) of D4 in the surface 0-1 cm of sediment, which represented about 1 year of sediment accumulation, were different between the four sections (p<0.01) and between years (p<0.01), with weak significant year-section interactions detected (p=0.19). Organic carbon normalized concentrations of D4 in the surface 0-1 cm of sediment showed net changes ranging from -26% to +164% over the 5-year sample collection period, but significant temporal trends were not detected (p>0.13) except Section 4 (p=0.04).
The sediment PEC at the regional scale was estimated as 7.9E-03 mg/kg dw (7.9 ng/g dw) (see Section 10.2.2). D4 concentrations in sediment collected from European urban areas are below this PEC. At the continental scale (which includes contributions from EU, EEA and UK sites), the freshwater sediment PEC was estimated by EUSES 2.1.2 at 3.98E-04 mg/kg dw (or 0.398 ng/g dw). D4 concentrations in sediment collected from urban areas in Scandinavia were comparable relative to PEC at the continental scale. Sediment samples collected from the Norwegian Arctic (Svalbard) in 2016 contained up to 0.85 ng/g ww of D4. At the Arctic scale, the sediment PEC was estimated by EUSES 2.1.2 at 4.18E-10 mg/kg dw (or 4.18E-07 ng/g dw).

Data on the presence of D4 in biota are available from studies performed by Reconsile members, institutional reports and peer-reviewed literature (Table 1.5). Most of the studies reported on specific prohibition on use of personal care products by all field and laboratory personnel in order to reduce potential for contamination of the samples.
The presence of D4 in biota has been monitored in freshwater system by Reconsile members and includes Lake Pepin, USA, Lake Ontario, Canada, Oslofjord, Norway and Tokyo Bay, Japan. For Lake Pepin, based on the existing data over the 5-year period (or 6 years of sample collection), lipid normalized concentrations (ng/g lw) of D4 were different between species (p<0.01) and between years (p<0.01), with significant year-species interactions detected (p<0.01). Lipid normalized concentrations of D4 in biota showed net changes ranging from –75% to +60, but significant temporal trends were not detected (p≥0.19). For Lake Ontario, based on the existing data over the 5-year period (or 6 years of sample collection), lipid normalized concentrations (ng/g lw) of D4 were different between species (p<0.01) and between years (p<0.01), with significant year-species interactions detected (p<0.01). Lipid normalized concentrations of D4 in biota showed net changes ranging from –61% to –0.4% over the 5-year sample collection period, but significant temporal trends were not detected (p>0.21).For the Oslofjord, based on the existing data over the 5-year period (or 6 years of sample collection), lipid normalized concentrations (ng/g lw) of D4 were different between species (p<0.01) and between years (p<0.01), with significant year-species interactions detected (p<0.01). Lipid normalized concentrations of D4 in biota showed net changes ranging from –61% to –23% over the 5-year sample collection period. Significant temporal trends were detected for Atlantic cod (p=0.02), but not for Atlantic herring or northern shrimp (p>0.31). In Tokyo Bay, based on the existing data over the 5-year period (or 6 years of sample collection), lipid normalized concentrations (ng/g lw) of D4 were different between species (p<0.01) and between years (p<0.01), with slightly weak significant year-species interactions detected (p=0.08). Lipid normalized concentrations of D4 in biota showed net changes ranging from -16% to 17% over the 5-year sample collection period, but significant temporal trends were not detected (p>0.51).
The concentrations cannot be compared to predictions from EUSES 2.1.2 because that model is very simplistic in respect to its approach to trophic magnification. The detailed study of bioaccumulation in the field is considered elsewhere as part of the bioaccumulation discussion (CSR Section 4.5).
