“…This is attributed to stingray ecology and preference for nearshore habitats that separate them from deeper, more diversely contaminated sediment where historic and current outfall pipes release wastewater (∼8 km offshore and >60 m deep). Although wastewater pharmaceuticals do have effects in biota that use habitat near the outfall pipes in southern California (Vidal‐Dorsch et al ), round stingray tissue previously tested for pharmaceutical contamination resulted in both low frequency of detections for measured compounds and low concentrations of those that were above the limit of detection (e.g., diphenhydramine, an antihistamine; Lyons et al ). Thus, PCBs represent the dominant contaminant at the mainland site.…”

Anthropogenic chemical exposure can result in overall reductions in reproductive success. Using the round stingray (Urobatis halleri) as an elasmobranch model with internal gestation, we measured female fecundity and embryo growth from postovulation to near parturition to test the hypothesis that environmental polychlorinated biphenyl (PCB) contamination would impair reproductive success. Two sites were sampled from southern California, USA: the mainland site was exposed to legacy PCB contamination (with low exposure to other anthropogenic contaminants), and the offshore reference site at Catalina Island was a separate population with low anthropogenic influence. Contaminant-exposed embryos weighed less at each stage of development than reference embryos, while accumulating proportionately more liver mass over development. Furthermore, environmental contamination negatively affected male embryos more than female embryos. The present study is the first study to demonstrate a negative effect of contaminant exposure on elasmobranch embryo growth, with probable fitness costs later in life.

“…Although there are many researches on contaminants removal from wastewater during its treatment process, studies on the toxicity removal of wastewater are still limited (Mendonca et al, 2013;Ma et al, 2013;Zhao et al, 2014;Zhang et al, 2013a). It was illustrated that conventional activated sludge technology used in WWTPs can effectively reduce the toxicity of wastewater to Vibrio fischeri Surujlal-Naicker et al, 2015), and A 2 /O treatment technology could successfully remove the acute toxicity of influent to zebrafish (Zhang et al, 2013a;Vidal-Dorsch et al, 2013). However, there is still no study on the comparison of toxicity removal by different treatment techniques.…”

The toxicity of municipal wastewater to the receiving water bodies is still unknown, due to the lack of regulated toxicity based index for wastewater discharge in China. Our study aims at gaining insight into the acute toxic effects of local municipal wastewater on alga, Scenedesmus obliquus. Four endpoints, i.e. cell density, chlorophyll-A concentration, superoxide dismutase (SOD) activity and cell membrane integrity, of alga were analyzed to characterize the acute toxicity effects of wastewater from municipal wastewater treatment plants (WWTPs) with different treatment techniques: sequencing batch reactor (SBR), Linpor and conventional activated sludge. Influent and effluent from each treatment stage in these three WWTPs were sampled and evaluated for their acute toxicity. Our results showed that all three techniques can completely affect the algal chlorophyll-A synthesis stimulation effects of influent; the algal cell growth stimulation effect was only completely removed by the secondary treatment process in conventional activated sludge technique; toxic effects on cell membrane integrity of two influents from WWTPs with SBR and conventional activated sludge techniques were completely removed; the acute toxicity on SOD activity was partially reduced in SBR and conventional activated sludge techniques while not significantly reduced by Linpor system. As to the disinfection unit, NaClO disinfection enhanced wastewater toxicity dramatically while UV radiation had no remarkable influence on wastewater toxicity. Our results illustrated that SOD activity and chlorophyll-A synthesis were relatively sensitive to municipal wastewater toxicity. Our results would aid to understand the acute toxicity of municipal wastewater, as well as the toxicity removal by currently utilized treatment techniques in China.

“…In earlier work by this same group examining gene expression patterns by microarray, the ability to distinguish patterns among sites was significantly improved when data from field caught flounder was combined with responses observed in controlled laboratory exposures . More recent work coming out of the Southern California Coastal Water Research Project (SCCWRP) on another flatfish, adult horneyhead turbot (Baker et al, 2009Vidal-Dorsch et al, 2013) also reveals complex patterns in gene expression, with many of the same transcripts examined in this study (CYP1A, VTG, HEP, GPDH) being differentially regulated in field caught turbot from sewage impacted areas of southern California and in turbot exposed to sewage effluent in the laboratory. However in the SCCWRP studies the direction of response was not always the same, with the laboratory exposed fish generally showing downregulation as compared to controls, while many of these transcripts were upregulated in field caught organisms.…”
