Reports of polychlorinated biphenyl (PCB) contamination of human milk have raised questions about the possible risks of breast-feeding and whether nursing mothers ought to have their breast milk tested. Current data on contamination of human milk are needed so that pediatricians can make informed recommendations about breast milk testing and breast-feeding. With consideration of recent findings of PCB contamination of human milk in Michigan, recommendations concerning breast milk testing and breast-feeding are made. No major changes in current breast-feeding practices are advised. However, breast milk testing is recommended for certain nursing mothers who have had potentially high exposure to PCBs. Limiting the duration of breast-feeding may also be advisable for mothers with high PCB milk fat levels in order to reduce infant exposure to PCBs.

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.
