“…Lampreys had accumulated PCDD/F and PCB congeners in relation to the congener concentrations in sediment. This is in agreement with the results of Soimasuo et al (2004) from Kyminlinna area in the R. Kymijoki. They concluded that generally the same major congeners were abundant both in lamprey larvae and sediment, although larvae and sediment congener profiles were not exactly identical.…”

“…They concluded that generally the same major congeners were abundant both in lamprey larvae and sediment, although larvae and sediment congener profiles were not exactly identical. Biota-sediment accumulation factors, BSAFs, for 1,2,3,4,7,8-HxCDD and 1,2,3,4,6,7,8-HpCDF that were also calculated in Soimasuo et al (2004) in R. Kymijoki, Kyminlinna area for lamprey larvae were similar compared to our study. BSAFs for PCBs were within the same range but on average considerably lower at the present study than in Soimasuo et al (2004), and only BSAF for PCB-52 was similar in both studies.…”

Lamprey larvae in the present study were analyzed with their gut contents, which as a rule may lead to overestimation of the true BSAFs.…”

“…Several studies have shown that due to their high lipid contents, lamprey larvae effectively bioaccumulate mercury and organic contaminants, such as PCDD/Fs and PCBs (e.g. Renaud et al 1999;MacEachen et al 2000;Soimasuo et al 2004;Isosaari et al 2006). Also some toxicity studies with lamprey eggs and larvae have been conducted (Myllynen et al 1997;Andersen et al 2010), but behavioural responses of lampreys to polluted sediments appear to be unexplored.…”

. (2016). Biological responses of midge (Chironomus riparius) and lamprey (Lampetra fluviatilis) larvae in ecotoxicity assessment of PCDD/F-, PCB-and Hg-contaminated river sediments. Environmental Science and Pollution Research, 23 (18), 18379-18393. doi:10.1007/s11356-016-7014-5 Abstract We evaluated utility of chironomid and lamprey larval responses in ecotoxicity assessment of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/F)-, polychlorinated biphenyls (PCB)-and mercury (Hg)-contaminated river sediments. Sediment samples were collected from the River Kymijoki with a known industrial pollution gradient. Sediment for the controls, and lamprey larvae were obtained from an uncontaminated river nearby. Contamination levels were verified with sediment and tissue PCDD/F, PCB and Hg analyses. Behaviour of sediment exposed chironomid and lamprey larvae were measured with Multispecies Freshwater Biomonitor© utilizing quadrupole impedance conversion technique. In addition, mortality, growth and head capsule deformity incidence of chironomids were used as ecotoxicity indicators. WHO PCDD/F+PCB -TEQ in the R. Kymijoki sediments ranged from the highest upstream 22.36 ng g -1 dw to the lowest 1.50 ng g -1 near the river mouth. Sum of PCDD/Fs and PCBs correlated strongly with Hg sediment concentrations, which ranged from <0.01 to 1.15 µg g -1 . Lamprey tissue concentrations of PCDD/Fs were two orders and PCBs one order of magnitude higher in the R. Kymijoki compared to the reference. Chironomid growth decreased in contaminated sediments, and was negatively related to sediment ∑PCDD/Fs, WHO PCDD/F+PCB -TEQ and Hg. There were no significant differences in larval mortality or chironomid mentum deformity incidence between the sediment exposures. The distinct behavioural patterns of both species indicate overall applicability of behavioural MFB measurements of these species in sediment toxicity bioassays. Chironomids spent less and lampreys more time in locomotion in the most contaminated sediment compared to the reference, albeit statistically significant differences were not detected. Lamprey larvae had also a greater activity range in some of the contaminated sediments than in the reference. High pollutant levels in lamprey indicate risks for biomagnification in the food webs, with potential health risks to humans consuming fish.Keywords: polychlorinated dibenzo-p-dioxins and -furans; polychlorinated biphenyls; mercury; sediment toxicity; Chironomus riparius; Lampetra fluviatilis; behaviour AcknowledgementsWe thank Tino Hovinen (University of Jyväskylä) and Rauni Kauppinen (Finnish Environment Institute) for their valuable help in the field and laboratory, and researchers in the National Institute of Health and Welfare for PCDD/F and PCB analyses.

“…In another study, PCBs and polychlorinated diphenyl ethers (PCDEs) were shown to bioaccumulate in river lamprey in Finland (Soimasuo et al, 2004). Soimasuo et al (2004) noted that the potential for developmental damages to lampreys from contamination of persistent organic pollutants is of concern, but had rarely been studied. A decade later, there is still little data on contaminant levels and effects on lamprey species, especially the Pacific lamprey.…”

Many anthropogenic disturbances have contributed to the decline of Pacific lampreys (Entosphenus tridentatus), but potential negative effects of contaminants on lampreys are unclear. Lamprey ammocoetes are the only detritivorous fish in the lower Willamette River, Oregon, USA, and have been observed in Portland Harbor sediments. Their long benthic larval stage places them at risk from the effects of contaminated sediment. The authors developed experimental methods to assess the effects of contaminated sediment on the growth and behavior of field-collected ammocoetes reared in a laboratory. Specifically, they developed methods to assess individual growth and burrowing behavior. Burrowing performance demonstrated high variability among contaminated sediments; however, ammocoetes presented with noncontaminated reference sediment initiated burrowing more rapidly and completed it faster. Ammocoete reemergence from contaminated sediments suggests avoidance of some chemical compounds. The authors conducted long-term exposure experiments on individually held ammocoetes using sediment collected from their native Siletz River, which included the following: contaminated sediments collected from 9 sites within Portland Harbor, 2 uncontaminated reference sediments collected upstream, 1 uncontaminated sediment with characteristics similar to Portland Harbor sediments, and clean sand. They determined that a 24-h depuration period was sufficient to evaluate weight changes and observed no mortality or growth effects in fish exposed to any of the contaminated sediments. However, the effect on burrowing behavior appeared to be a sensitive endpoint, with potentially significant implications for predator avoidance. Environ Toxicol Chem 2016;35:2092-2102. © 2016 SETAC.
