Xuchun Qiu, Sang Gyoon Kim, Ikjoon Kang, Takeshi Hano, Yohei Shimasaki, Yuji Oshima, Combined toxicities of tributyltin and polychlorinated biphenyls on the development and hatching of Japanese medaka (Oryzias latipes) embryos via in ovo nanoinjection, Chemosphere, 10.1016/j.chemosphere.2019.03.104, 927-934, 2019.06, Tributyltin (TBT) and polychlorinated biphenyls (PCBs) are typical organic pollutants that co-exist in the aquatic environment. Despite increasing awareness of their combined impacts, knowledge about their potential interactive effects remains limited. In this study, we investigated the effects of TBT-PCBs mixtures on the survival, development, and hatching of embryos of Japanese medaka (Oryzias latipes). Our goal was to assess the interactive effects of TBT and PCBs on early-life-stage fish. We used in ovo nanoinjection to simulate the maternal transfer process and to control exposure doses at 0, 7.5, 15, 30 ng/g-egg (for both toxins). A factorial design (4 × 4) corresponding to the above doses was used to define the formulation of mixtures. Results showed that injection of mixtures of TBT and PCBs into fertilized eggs caused significantly elevated rates of mortality, yolk-sac shrinkage, swim-up failure, and deformities of medaka embryos/larvae. TBT and PCBs interacted synergistically to induce the above developmental abnormalities. In contrast, exposure to only TBT increased the hatching times of embryos, whereas exposure to only PCBs decreased the hatching times. The dose ratios, dose levels, and interactive effect of TBT and PCBs in a mixture played significant roles in determining the final impact on time-to-hatching. Our results suggested that in ovo exposure to a mixture of TBT and PCBs may interact synergistically to induce developmental abnormalities in fishes..

Xuchun Qiu, Naoto Iwasaki, Kun Chen, Yohei Shimasaki, Yuji Oshima, Tributyltin and perfluorooctane sulfonate play a synergistic role in promoting excess fat accumulation in Japanese medaka (Oryzias latipes) via in ovo exposure, Chemosphere, 10.1016/j.chemosphere.2018.12.191, 220, 687-695, 2019.04, The ubiquitous environmental obesogens tributyltin (TBT) and perfluorooctane sulfonate (PFOS) may accumulate in parent and be transferred to their offspring, resulting in trans-generational adverse effects. In this study, we investigated the combined toxic and obesogenic effects of TBT and PFOS on the early life stages of Japanese medaka (Oryzias latipes). In ovo nanoinjection was used to simulate the maternal transfer process. Doses were controlled at 0, 0.05, 0.5, and 2.5 ng/egg (TBT) and at 0, 0.05, 0.5, and 5.0 ng/egg (PFOS), with a full factorial design for mixture formulations. Relatively high doses of agents in mixtures were needed to induce significant mortality (TBT ≥ 0.5 ng/egg) or delayed hatching (PFOS = 5.0 ng/egg) of embryos. The interaction between TBT and PFOS in mixtures had significant effects on the observed hatching delay, but not on acute mortality. Compared with controls, separate exposure to TBT (or PFOS) notably elevated adipose areas at the doses of 0.05 and 0.5 ng/egg, but not at the highest doses. Combined exposure significantly promoted the fat accumulation in newly hatched larvae, even when the doses of TBT and PFOS were both at the levels that did not show obesogenic effect. The interactive effect of TBT and PFOS could aggravate the total obesogenic effect of their mixtures, indicating a synergistic interaction. These results highlight the importance of paying close attention to interaction effects when addressing the impacts of mixtures of environmental obesogens..

Treating the embryos with one of two single-guide RNA (sgRNA) resulted in mutation rates of 57.1% and 62.5%, respectively, as estimated using a heteroduplex mobility assay at 3 days postfertilization. Both sgRNAs might induced frameshift mutations that knocked out the T. rubripes PSTBP2..

Sci. Total Environ. . doi:10.1016/j.scitotenv.2017.07.034, Sci. Total Environ., 10.1016/j.scitotenv.2017.07.034, 607-608, 367-374, 2018.01, Organisms in natural environments are often exposed to a broad variety of chemicals, and the multi-chemical mixtures exposure may produce significant toxic effects, even though the individual chemicals are present at concentrations below their no-observed-effect concentrations. This study represents the first attempt that uses the accelerated failure time (AFT) model to quantify the interaction and toxicity of multi-chemical mixtures in environmental toxicology. We firstly conducted the acute immobilization tests with Daphnia magna exposed to mixtures of diazinon (DZN), fenitrothion (MEP); and thiobencarb (TB) in single, binary, and ternary formula- tions, and then fitted the results to the AFT model. The 48-h EC50 (concentration required to immobilize 50% of the daphnids at 48 h) values for each pesticide obtained from the AFT model are within a factor of 2 of the cor- responding values calculated from the single pesticide exposure tests, indicating the methodology is able to pro- vide credible toxicity values. The AFT model revealed either significant synergistic (DZN and MEP; DZN and TB) or Daphnia magna.

Sound production was affected by exposure to the carbamate insecticide (aldicarb) and heavy-metal compound (copper sulfate). Medaka were exposed at four concentrations (aldicarb: 0, 0.25, 0.5, and 1 mg L−1; copper sulfate: 0, 0.5, 1, and 2 mg L−1), and sound characteristics were monitored for 5 h after exposure. We observed constant average interpulse intervals (approx 0.2 s) in all test groups before exposure, and in the control groups throughout the experiment. The average interpulse interval became significantly longer during the recording periods after 50 min of exposure to aldicarb, and reached a length of more than 0.3 s during the recording periods after 120 min exposure. Most medaka fish stopped to produce sound after 50 min of exposure to copper sulfate at 1 and 2 mg L−1, resulting in significantly declined number of sound pulses and pulse groups. Relative shortened interpulse intervals of sound were occasionally observed in medaka fish exposed to 0.5 mg L−1 copper sulfate. These alternations in sound characteristics due to toxicants exposure suggested that they might impair acoustic communication of medaka fish, which may be important for their reproduction and survival. Our results suggested that using acoustic changes of medaka has potential to monitor precipitate water pollutions, such as intentional poisoning or accidental leakage of industrial waste..

Relative high concentrations of 110mAg (2.1–127 Bq kg-wet−1), 134Cs (2.6–61 Bq kg-wet−1), and 137Cs (3.5–92 Bq kg-wet−1) were detected in specimens from the eastern Honshu areas. Significantly lower 137Cs concentrations (0.7–1.6 Bq kg-wet−1) were detected in specimens from western and northern Honshu. The decay-corrected 137Cs concentration was significantly inversely correlated with the distance from the Fukushima Dai-ichi Nuclear Power Plant. Thus, wharf roach may serve as a good bioindicator for monitoring radioactive contamination of its habitats..

Medaka were exposed to 6.15 mg L−1 CBMZ, 1.0 mg L−1 DCF, 0.17 mg L−1 TCS, or no PPCP (control) for 9 d. Fish behaviors were monitored during days 5–9 of the exposure period. Feeding behavior (time to eat midge larvae, TE) and swimming speed (SS) of individual exposed and control fish were tracked in two dimensions, using an automated system with a digital charge-coupled device camera. As a result, feeding behavior was affected by exposure to CBMZ and DCF, while SS was altered by exposure to CBMZ and TCS. Thus, TCS, DCF and CBMZ appear to affect fish behaviors through different mechanisms. Overall, the results suggest that behavioral changes may provide a sensitive indicator for assessing the toxicity of PPCPs to aquatic organisms..
