We investigated the pollution levels of 6 heavy metals and 29 dioxins (polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (DL-PCBs)) in intertidal and supratidal zones by using wharf roaches (Ligia spp.) collected from 12 sampling sites on the coast of Northeast Japan from November 2011 to June 2012. The total concentrations of heavy metals ranged from 177 to 377 µg/g-dry weight (dw), and the predominant metals were copper, zinc, and aluminum. The order of the detected level of heavy metals was zinc > aluminum > copper > cadmium > lead > chromium, and this trend was similar to a previous report. The total toxic equivalent (TEQ) value of the PCDD/Fs ranged from less than the limit of detection (<LOD) to 2.33 pg-TEQ/g-dw, and the predominant congener was octachlorodibenzodioxin (<LOD to 110 pg/g-dw). Compared with PCDD/Fs, DL-PCBs were detected at a predominantly higher level (total TEQ value: 0.64–27.79 pg-TEQ/g-dw). Detected levels of dioxins, especially DL-PCBs in the wharf roach, were like those in the bivalves. These results indicate that the wharf roach could reflect heavy metals and dioxin pollution in the supratidal zones and is a suitable environmental indicator for these environmental pollutants. This is the first study to investigate heavy metals, PCDD/Fs, and DL-PCBs pollution in coastal isopods in Japan.

Abstract How an organism copes with chemicals is largely determined by the genes and proteins that collectively function to defend against, detoxify and eliminate chemical stressors. This integrative network includes receptors and transcription factors, biotransformation enzymes, transporters, antioxidants, and metal- and heat-responsive genes, and is collectively known as the chemical defensome. Although the types of defensome genes are generally conserved in animals, there are important differences in the complement and function of specific genes between species. Teleost fish is the largest group of vertebrate species and can provide valuable insights into the evolution and functional diversity of defensome genes.In this study, we compared the genes comprising the chemical defensome of five fish species that span the teleosteii evolutionary branch often used as model species in toxicological studies and environmental monitoring programs: zebrafish (Danio rerio), Atlantic cod (Gadus morhua), medaka (Oryzias latipes), Atlantic killifish (Fundulus heteroclitus) and three-spined stickleback (Gasterosteus aculeatus). Genome miningrevealed evolved differences in the number and composition of defensome genes that can have implication for how these species sense and respond to environmental pollutants. The results indicate that knowledge regarding the diversity and function of the defensome will be important for toxicological testing and risk assessment studies.

Analytical Approaches

ABSTRACT Polychlorinated biphenyls (PCBs) are environmental pollutants of industrial origin that can contaminate food, mainly food of animal origin. Although production of PCBs has been banned in many countries since the 1980s, they are still present in the environment and are considered dangerous pollutants for human health. In fact, they can bioaccumulate in living organisms such as marine organisms because of their chemical and physical properties. New analytical approaches are useful to monitor the presence of such contaminants in seafood products and in the environment. In this work, we evaluate changes in protein expression of Mytilus galloprovincialis (Lam.) experimentally exposed to a PCB mixture and identify chemically specific protein expression signatures by using a proteomic approach. In particular, we identify 21 proteins whose levels of expression are sensibly modified after 3 weeks of exposure. The present work shows that a proteomic approach can be a useful tool to study alterations of protein expression in mussels exposed to PCBs and represents a first step toward the development of screening protocols to be used for biomonitoring surveys of fishery products.
