“…SM were also discharged into Xukou Bay from the Xujiang River and Siqian River, which receive municipal sewage and industrial wastewater from Suzhou City. Previous studies have shown that the removal efficiency for HHCB and AHTN in a wastewater treatment plant ranged from 63 % to 88 %, and 64 % to 89 %, respectively (Simonich et al 2002;Bester 2004;Kupper et al 2006;Hu et al 2011b), with the remainder being discharged in the effluent typically into a surface water body. The ''downthe-drain'' route is regarded as the primary pathway for SM into aquatic ecosystem.…”

A total of thirty-three surface water samples were collected from Meiliang Bay, Gonghu Bay and Xukou Bay of Lake Taihu, and analyzed for synthetic musks, including 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta-[c]-2-benzopyrane (HHCB), 7-acetyl-1,1,3,4,4, 6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN), 1-tertbutyl-3,5-dimethyl-2,5-dinitro-4-acetylbenzene (MK) and 1-tert-butyl-3,5-dimethyl-2,4,6-trinitrobenzene (MX). Ecological risks of these compounds were characterized by hazard quotient (HQ) method due to a lack of sufficient available toxicity data of synthetic musks. HHCB was the main synthetic musk detected in Lake Taihu, followed by AHTN, MK, and MX. The risk assessment results indicate that low ecological risks were posed by HHCB and total synthetic musks, and even lower risks posed by other synthetic musks in the worst case; much lower ecological risks were caused by both individual and total synthetic musks in the general case. The combined ecological risk from total synthetic musks calculation suggests that the combined ecological risk from all four synthetic musks was expected to be slightly higher than for the individual musks due to their joint action. The HQ spatial distribution maps show that several hot-spot areas were mainly around the river inlets to Lake Taihu, indicating that synthetic musks may be transported to Lake Taihu with municipal sewage and industrial wastewater from surrounding areas. However, the ecological risks in hot-spot areas posed by individual and total synthetic musks were still acceptable.

“…The AC concentration used in the present study (50 μg g −1 dw sediment), resulting in substantial mortality of C. teleta, is presumably higher than concentrations that can be expected in the field. Simonich et al (2000Simonich et al ( , 2002 measured the concentrations of AC in wastewater influent and effluent to be in the range of 2610-8110 and 76-1,359 ng l −1 , respectively. According to Salvito et al (2002) the predicted environmental concentration, PEC, for fragrance materials can be calculated from the effluent concentration divided by a threefold dilution factor: PEC = 2° eff.…”

“…The primary route to the environment is through down-the-drain disposal of these products (Simonich et al 2000(Simonich et al , 2002. Fragrance materials have been found in wastewater in a number of wastewater treatment plants in Europe and the USA (Artola-Garicano et al 2003b;Osemwengie and Gerstenberger 2004;Osemwengie and Steinberg 2001), and a few studies have detected acetyl cedrene (AC) (Simonich et al 2000(Simonich et al , 2002. The fate of fragrance materials in the aquatic environment can either involve sorption to particles and sedimentation, accumulation in aquatic organisms, (bio)degradation or volatilization to the atmosphere (Osemwengie and Gerstenberger 2004;Salvito et al 2002).…”

Investigation of the fate and effects of acetyl cedrene on Capitella teleta and sediment bacterial community

"Investigation of the fate and effects of acetyl cedrene on Capitella teleta and sediment bacterial community" (2010). Valery Forbes Publications. 10. http://digitalcommons.unl.edu/biosciforbes/10 AbstractThe fate of the fragrance material, acetyl cedrene (AC), in sediment was examined in a 16 day laboratory experiment using the sediment microbial community subjected to the following treatments: AC (nominal concentration; 0 and 50 μg g −1 dw sediment) and macrofaunal worms (with/without Capitella teleta (formerly Capitella sp. I)). Furthermore effects of AC on microbial respiration in the system were determined by examining CO 2 flux. T-RFLP (terminal restriction fragment length polymorphism) was used to analyze PCR (polymerase chain reaction) amplified 16S DNA gene fragments from the sediments to detect changes in the structure and diversity of the bacterial community. In addition, survival of C. teleta in sediment was determined. Lastly, we examined how the interactions between microbes and C. teleta in the sediment affected the above-mentioned parameters. The results showed that there was an interaction between worm treatment and time of sampling on the loss of AC from the sediment. This was caused by AC loss initially being fastest in the sediment with C. teleta present, but at experimental termination there was no significant difference between the two treatments (i.e., with/ without worms) in the amount of AC remaining in the sediment. Survival of C. teleta was significantly reduced by AC at experimental termination, but neither microbial respiration nor structure and diversity of the bacterial community were significantly affected.

“…Other authors found that Benzyl Salicylate gives oestrogenic responses in human breast cancer cells, potentially promoting the development of this disease (Charles and Darbre, 2009). The concentrations of Benzyl and Hexyl Salicylates were measured in U.S. and European wastewater treatment plants (WWTPs) (Simonich et al, 2002(Simonich et al, , 2000, where were reported almost quantitative removals (98.7%) of these substances after secondary treatment. Benzyl Salicylate was detected in other WWTPs in Spain (Godayol et al, 2015;Negreira et al, 2010) and Japan (Kameda et al, 2011), reporting similar removals.…”

• Fragrance Materials (FMs) were quantified in the surface waters of the Venice lagoon.• First detection in environmental samples of most of the selected FMs.• Salicylates resulted in general the most abundant and widespread compounds.• FMs are persistently emitted in the environment.• Emitting sources and tidal dilution resulted key factors. Fragrance Materials (FMs) are omnipresent components of household and Personal Care Products (PCPs). In spite of their widespread use, little is known about their environmental occurrence. We selected 17 among the longest-lasting and most stable fragrance ingredients that are commercially available, namely: Amberketal, Ambrofix, Amyl Salicylate, Benzyl Salicylate, Bourgeonal, Dupical, Hexyl Salicylate, Isobutavan, Lemonile, Mefranal, Myraldene, Okoumal, Oranger Crystals, Pelargene, Peonile, Tridecene-2-Nitrile, Ultravanil. A new analytical method was developed to quantify FMs in water samples and it was applied to perform the first study about the distribution of these compounds in the surface waters of the city of Venice and its lagoon. Total FMs concentrations range from about 30 ng L −1 to more than 10 μg L −1 in polluted canals during the low tide. Sewage discharges were supposed to be the main sources of the selected FMs in the environment. Salicylates, oestrogenic and allergenic compounds, were in general the most abundant and widespread components. This study reports for the first time the detection of most of the selected FMs in surface waters and represent the first step to understand their environmental fate.
