“…But GCB also showed strong absorption for most target compounds as discussed above. As reported by other scientists, Z-Sep sorbent can provide cleaner extracts than PSA/C18 sorbent for fish muscle [31]. In our study, Z-Sep can slightly enhance the co-extractive removal efficiency, but it also induces a low recovery of imazalil-D 5 .…”

“…The maximum detected concentrations for HHCB and BT were up to 119 and 54.6 ng/g ww in liver samples, respectively. The results of wide detection of DEET, AHTN, and HHCB were inconsistent with those reported by Baduel C et al and Picot Groz M et al [31,61]. The investigated rivers receive discharge of domestic wastewaters from the cities in the region [7].…”

“…The analytes determined by LC-MS/MS were more likely to be suppressed rather than enhanced by matrices in this study [31], since coeluting compounds tend to compete for either the total available charge or the available surface area of the droplet in the surface of the MS detector and then result in the ion suppression of the analyte [52]. For DEET and icaridin, obvious matrix enhancement effects were observed, which is often the case with biological and environmental samples due to the complicated interaction between analytes and matrices [28,53].…”

“…Matrix-induced response enhancement is common in GC-MS analysis [31]. The components in matrices can partially deactivate the active sites and reduce the thermal stress, which improves mass transfer of the analyte to the detector [56].…”

“…Due to its prominent merits, the QuEChERS extraction method is now rapidly developed and used in the analysis of various pharmaceuticals and persistent organic pollutants in soil, sediment, and water matrices [28,29]. QuEChERS procedures also were successfully applied to the analysis of non-polar and semi-polar chemicals in fatty food matrices salmon, seafood, milk, and fish muscle using GC-MS/MS or LC-MS/MS [30][31][32].…”

A sensitive and selective quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction combined with dispersive solid-phase extraction (d-SPE) cleanup method was developed to simultaneously extract a wide range of personal care products (16 biocides, 4 synthetic musks, and 4 benzotriazoles) in fish muscle and liver tissues. In order to get satisfactory recoveries, different extraction parameters were optimized, including extraction salts and d-SPE materials, extraction solvents and acetic acid contents in organic phase, and the ratios of solvent and water. Ultra pressure liquid chromatography-tandem mass spectrometry and gas chromatography-mass spectrometry were used to analyze the target compounds in the extracts. Among the 24 personal care products, the recoveries in the range of 70-120 % were obtained for 20, 19, and 12 analytes in fish muscle at the spiking concentrations of 10, 5, and 1 ng/g ww, respectively, and for 13, 12, and 11 analytes in liver at the spiking concentrations of 40, 20, and 4 ng/g ww, respectively. Method quantification limits (MQLs) of all analytes were 0.02-2.12 ng/g ww for fish muscle and 0.22-12.2 ng/g ww for fish liver tissues. The method was successfully applied to wild fish samples collected from Dongjiang River, south China. Twenty-one and 17 of the analytes were found in fish muscle and liver samples, respectively, in at least one site of the river with the concentrations between below MQLs and 119 ng/g ww, respectively.

Understanding environmental contributions to autism: Causal concepts and the state of science

This Keynote Lecture, delivered at the 2016 meeting of the International Society for Autism Research, discusses evidence from human epidemiologic studies of prenatal factors contributing to autism, such as pesticides, maternal nutrition and her health. There is no single cause for autism. Examples highlight the features of a high-quality epidemiology study, and what comprises a compelling case for causation. Emergent research directions hold promise for identifying potential interventions to reduce disabilities, enhance giftedness, and improve lives of those with ASD.
