Several unknown, abundant brominated compounds (BCs) were recently detected in the blubber of dolphins and other marine mammals from Queensland (northeast Australia). The BCs interpreted as potential natural products due to lack anthropogenic sources for these compounds. This study investigated whether some accumulated by diverse mammal species are identical with previously isolated sponges (Dysidea sp.) living same habitat. Isolates mollusks (Asteronotus cespitosus) compared signals...
To simultaneously quantify and profile the complex mixture of short-, median-, long-chain CPs (SCCPs, MCCPs, LCCPs) in Australian sewage sludge, we applied further validated a recently developed novel instrumental technique, using quadrupole time-of-flight high resolution mass spectrometry running negative atmospheric pressure chemical ionization mode (APCI-qTOF-HRMS). Without an analytical column cleaned extracts were directly injected into qTOF-HRMS followed by quantification mathematical...
Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) may be formed during the manufacture of chlorinated pesticides, can remain in products as impurities. However, contemporary release PCDD/Fs to environment from pesticide use is poorly understood. For this study, 27 formulations were analyzed for (n = 23 registered Australia). PCDD/F impurities present all samples, ranging 0.020 2100 ng ΣPCDD/F g−1 active ingredient (AI). Among current pentachloronitrobenzene (PCNB) contained...
Quantification of bioaccumulative contaminants in biota is time and cost-intensive the required extensive cleanup steps make it selective toward targeted chemical groups. Therefore tissue extracts prepared for analysis are not amenable to assess combined effects unresolved complex mixtures. Passive equilibrium sampling with polydimethylsiloxane (PDMS) has potential unbiased mixtures, PDMS can be directly dosed into cell-based bioassays. The passive approach was tested by exposing lipid-rich...
Some methoxylated polybrominated diphenyl ethers (MeO-BDEs) are known halogenated natural products (HNPs) and frequently detected in higher organisms of the marine environment. In this study we demonstrate that a prominent MeO-BDE, previously mammals from Australia, is identical to 3,5-dibromo-2-(2',4'-dibromo)phenoxyanisole (BC-3, 6-MeO-BDE 47). Up 1.9 mg/kg 47 was present cetaceans 0.2−0.3 two crocodile eggs but concentrations 1 or 2 orders magnitude lower were found shark liver oil New...
An as yet unidentified origin of elevated concentrations polychlorinated dibenzo-p-dioxins (PCDDs) in soil and sediment has repeatedly been described from different locations around the world, including Australia. Natural sources have hypothesized to account for such contamination, which is characterized by a distinctive dioxin profile, particular, levels octachlorodibenzo-p-dioxins (OCDD) well relatively low contributions dibenzofurans (PCDFs). The present study investigated whether OCDD...
In recent years, studies on environmental samples with unusual dibenzo-p-dioxin (PCDD) congener profiles were reported from a range of countries. These profiles, characterized by dominance octachlorinated dibenzodioxin (OCDD) and relatively low in dibenzofuran (PCDF) concentrations, could not be attributed to known sources or formation processes. the present study, processes that result these assessed using concentrations isomer signatures PCDDs dated estuarine sediment cores Queensland,...
