“…So only comparisons for the surveyed concentrations of emerging BFRs, HBCD and Dechloranes in sludge from Chinese WWTPs with those available from other countries are presented in SI Table S5−S7, respectively. As shown in SI Table S5, the mean DBDPE concentration (52.2 ng g −1 ) in sludge in China was comparable to those reported in Spain, 25,27,31 Singapore, Sweden, England, Germany, the Czech Republic and South Africa, 30 and comparatively higher than those in Australia, the U.S., Canada, New Zealand, 30 and Norway, 33 but evidently lower than the values found in Korea (237 ng g −1 ) 22 and Switzerland (128 ng g…”

Occurrence of new toxic chemicals in sludge from wastewater treatment plants (WWTPs) is of concern for the environment and human health. Alternative halogenated flame retardants (HFRs) are a group of potentially harmful organic contaminants in the environment. In this study, a nationwide survey was carried out to identify the occurrence of HFRs and their potential dehalogenated products in sewage sludge from 62 WWTPs in China. Of all 20 target chemicals analyzed, decabromodiphenyl ethane (DBDPE), hexabromocyclododecane (HBCD) and 1, 2-bis (2,4,6-tribromophenoxy)-ethane (BTBPE) were detected in all sludge samples, and the concentrations were in the range of 0.82−215, 0.09−65.8, and 0.10−2.26 ng g −1 d.w., respectively. Dechlorane Plus (DP) was found in 60 of 62 samples, and the concentration ranged from nd−298 ng g −1 with a mean of 18.9 ng g −1 d.w. The anti-DP fractional abundance f anti (0.79) in the samples was much higher than the commercial DP composition (f anti = 0.59), indicating a stereoselective degradation. Comparison with global sludge concentrations of HFRs indicate that China is at the medium pollution level in the world. Principal components analysis revealed that strong correlations existed between ln-transformed concentrations (natural logarithm) of the dominant BFRs and total organic carbon (TOC) as well as industrial wastewater proportion, influent volume and serving population. Significant linear relationships (R = 0.360−0.893, p < 0.01) were found among emerging brominated flame retardants (BFRs), suggesting their common commercial applications and release sources to the environment. Two kinds of dehalogenated products, pentabromocyclododecane (PBCD) and undecachloropentacyclooctadecadiene (Cl 11 -DP), derived from HBCD and DP, were also identified in sewage sludge for the first time.

“…Despite such developments, Soxtec does not improve on the scarce versatility of the conventional Soxhlet device. Only 7% of the reports reviewed here have employed the Soxhlet technique [20,21,22,23,24] (Table 1) as also observed in the previous review published in 2012 [14]. Despite the development of Soxtec, the publications mentioned above used Soxhlet as the extraction technique.…”

“…As implemented in the U.S., Canada also supports the virtual voluntary elimination of DecaBDE by 2013 [29]. Industries are producing new brominated flame retardants which are now being measured in the environment [30,31] and show bioaccumulation in various organisms [32-34]. The new flame retardants products represent contaminants of emerging concerns and the persistence of the older ones such as PCBs and PBDEs are highly persistent in the environment and still an environmental problem particularly in aquatic systems where sediments are recognized as a sink for this class of contaminant.…”

A review is presented of how one defines emerging contaminants and what can be included in that group of contaminants which is preferably termed “contaminants of emerging concern”. An historical perspective is given on the evolution of the issues surrounding emerging contaminants and how environmental scientists have tackled this issue. This begins with global lead contamination from the Romans two millennia ago, moves on to arsenic-based and DDT issues and more recently to pharmaceuticals, cyanotoxins, personal care products, nanoparticles, flame retardants, etc. Contaminants of emerging concern will remain a moving target as new chemical compounds are continuously being produced and science continuously improves its understanding of current and past contaminants.
