“…Sumner et al (2010) observed that an area that received effluent from a sewage treatment plant also had high concentrations of SM in its estuarine and coastal environment. Many studies have reported that concentrations of SM can vary widely, depending on the volume of treated sewage, the types of wastewater, and treatment processes (Lv et al 2010;Guo et al 2010). Generally, the removal mechanisms of SM from sewage plants include biological transformation, chemical transformation, and volatilization (Reiner et al 2007;Berset et al 2004).…”

“…Generally, the removal mechanisms of SM from sewage plants include biological transformation, chemical transformation, and volatilization (Reiner et al 2007;Berset et al 2004). It was reported that chemical transformation, especially oxidation, might play an important role in synthetic musk elimination (Lv et al 2010), while the volatilization in the removal of SM could be negligible due to their low Henry coefficient (K H \ 3.0 9 10 -7 ). Accordingly, it is necessary to select effective treatment processes for the elimination of SM in order to reduce the discharge of effluent from wastewater treatment plant.…”

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.

“…An examination of the literature demonstrates an unsystematic approach to the collection of important site characteristics, and in some instances, no information is provided (Table 2). Site characteristics are sometimes obtained from previous publications, surveys, and reports (Table 2), but this is ill advised; there can be significant diurnal and seasonal cycles of chemical concentrations such as EDCs [76][77][78].

Scientific reviews and studies continue to describe omics technologies as the next generation of tools for environmental monitoring, while cautioning that there are limitations and obstacles to overcome. However, omics has not yet transitioned into national environmental monitoring programs designed to assess ecosystem health. Using the example of the Canadian Environmental Effects Monitoring (EEM) program, the authors describe the steps that would be required for omics technologies to be included in such an established program. These steps include baseline collection of omics endpoints across different species and sites to generate a range of what is biologically normal within a particular ecosystem. Natural individual variability in the omes is not adequately characterized and is often not measured in the field, but is a key component to an environmental monitoring program, to determine the critical effect size or action threshold for management. Omics endpoints must develop a level of standardization, consistency, and rigor that will allow interpretation of the relevance of changes across broader scales. To date, population-level consequences of routinely measured endpoints such as reduced gonad size or intersex in fish is not entirely clear, and the significance of genome-wide molecular, proteome, or metabolic changes on organism or population health is further removed from the levels of ecological change traditionally managed. The present review is not intended to dismiss the idea that omics will play a future role in large-scale environmental monitoring studies, but rather outlines the necessary actions for its inclusion in regulatory monitoring programs focused on assessing ecosystem health.

“…However, the wash-off products represent the greater emission source (97%). For instance, the shampoo contributes for 71% of the emissions (mean: 4.3 mg capita -1 day -1 ; maximum: 34.9 mg capita -1 day -1 ), followed by the shower gel (17%; (Homem et al, 2015;Clara et al, 2011;Lv et al, 2010;Zhang et al, 2008;Horii et al, 2007;Yang and Metcalf, 2006;Bester, 2004;Kupper et al, 2004).…”

Scented traces – Dermal exposure of synthetic musk fragrances in personal care products and environmental input assessment

et al. 2015

Synthetic musks are organic compounds used as fragrance and fixative additives in several personal care products. Until now, little is known about their occurrence and distribution in these household commodities. However, this information is essential to perform a human dermal exposure assessment. Therefore, this study gives an overview on the levels of 12 synthetic musks in 140 personal care products from 7 different categories (body and hair wash, toilet soaps, shaving products, dentifrice products, deodorants/antiperspirants, moisturizers and perfumes).They were analysed by QuEChERS extraction followed by gas chromatography-mass spectrometry. Detection limits were found between 0.01 ng g -1 (galaxolide) and 5.00 ng g -1 (musk xylene galaxolide, and 15% tonalide, while for babies/children 96% occurs due to exaltolide.An estimate of the amount of musks discharged "down-the-drain" into the wastewater treatment systems through the use of toiletries was also performed. An average emission per capita of 6.7 mg day -1 was determined and galaxolide and exaltolide were the predominant musks in the effluents.
