“…However, there are few studies using solid phase extraction (SPE) cartridges for the simultaneous extraction and clean-up of polycyclic musks and nitro musks in aquatic matrices. Although Osemwengie et al 29 described an on-site SPE procedure for the SMs, the wide application of this method is impractical as it required filters, pumps and ancillary supplies to handle 60-liter volume for each sample. To our knowledge, there is no report on the simultaneous extraction of polycyclic musks and nitro musks from aquatic matrices in the sample volume of one liter or less using SPE cartridges.…”

This study intended to develop a robust and sensitive method for simultaneous determination of polycyclic musks (HHCB and AHTN) and nitro musks (musk xylene (MX) and musk ketone (MK)) in water samples using optimized solid-phase extraction (SPE) by gas chromatography and mass spectrometry (GC-MS). The SPE procedure was optimized in terms of selections of SPE cartridge, sample pH, elution process, etc. The method detection limits (MDLs) were from 0.09 to 0.18 ng L -1 for the analytes. The recoveries ranged from 88.3 to 104.1% in spiked deionized water and from 86.4 to 106.8% in groundwater samples, respectively. The proposed approach was also validated by detecting real samples. The results revealed that HHCB and AHTN were ubiquitous in the local aquatic matrices. Furthermore, nitro musks were found in some aquatic matrices, which is consistent with the fact that nitro musks are still being produced and applied in China.

“…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" (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.

“…The emission was monitored by analysing water samples and eel samples, respectively. Very recent results indicate HHCB and AHTN as suitable tracers for the US and Canada, too (Osemwengie and Steinberg, 2001;Ricking et al, 2002b).…”
