The Mid-Canada Radar Line (MCRL) was built by the Canadian government during the 1950s and closed in the 1960s. MCRL Site 050 located in close proximity to Fort Albany First Nation was a source of polychlorinated biphenyls (PCBs); thus, this site was remediated in 2001. There has been concern in Fort Albany that the Albany River by MCRL Site 050 is still contaminated. We examined whether the aquatic environment surrounding MCRL Site 050 has returned to background levels four years post-remediation using leeches (Haemopis spp.) as bioindicators. Leech data for 2005 indicates that PCB levels remain higher near Site 050 than at the control site upstream; however, there has been a decrease in difference between Site 050 and the control site for leech body burden between years. Thus, the removal of the terrestrial source of PCB contamination at Site 050 appears to have removed the main source of aquatic PCBs.

“…Organisms tolerant of TFM detoxify the accumulated chemical by conjugation with glucuronic acid (Kawatski & Bittner, 1975) . In contrast, TFM sensitive taxa such as the annelid worms and leeches (Maki & Johnson, 1977 ;Metcalfe et al, 1984) accumulate TFM but are unable to biotransform the compound to a less toxic form . This may be true also for some aquatic insects that are sensitive to the lampricide .…”

Effects of the lampricide, 3-trifluoromethyl-4-nitrophenol (TFM) on the macroinvertebrates of a hardwater river

et al. 1986

The effects of the lampricide, TFM, on the benthic macroinvertebrates in the Rouge River, a hardwater tributary to Lake Ontario was examined at 1 untreated and 2 treated sites over a 7 month period . Drift samples were collected from one one of the treated sites during the 5 days bracketing treatment . Significant decreases in relative abundance attributable to TFM were recorded for Chimarra sp ., Dugesia sp. and Tubificoidea 2-19 d following treatment . Large reductions were also (l hibited by Caenis sp . and Lumbricidae. Two-thirds of the Chironomidae genera and Nematoda tended to decline in abundance 2 d after treatment at only one of the treated sites, probably due to a 2 .5 h longer treatment . This decline was followed by a significant increase to greater than pretreatment abundances 17 d later undoubtedly as a result of an upward migration of macroinvertebrates from within the hyporheos . Partial recolonization of the TFM-sensitive benthic taxa was evident 19 d after lampricide treatment with complete recolonization 6 .5 months later. With

“…This study was undertaken to determine the basic life histories and feeding habits of these cooccurring species in an enriched, perennial stream. Such information is essential to understanding the role of these predators in streams and the ways in which leeches accumulate organic contaminants (Metcalfe et al 1984).…”

1986. Life cycles, reproduction, and diets of Dina dubia and Erpobdella punctata (Hirudinea: Eropobdellidae) in Canagagigue Creek, Ontario. Can. J. Zool. 64: 640-648. The life cycles of Dina dubia and Erpobdellapunctata were described from semimonthly (monthly in winter) collections made at two sites on Canagagigue Creek between May 1982 and July 1983. Observations on reproduction were made in the creek and in a flow-through stream tank. Most individuals of both species completed their life cycles in about 1 year, but some required 2 or more years to reach sexual maturity. The estimated average fecundity (1 38-173 young/adult), growth rate, and maximum size (1946 mg live weight) of E. punctatu were all greater than for D. dubia (47-50 young/adult; maximum size, 725 mg), but D. dubia was much more abundant in Canagagigue Creek. Both species fed most frequently on Chironomidae and Oligochaeta, with the total variety of prey consumed reflecting the diversity of prey available at the site. The habitat preferences of the leeches were apparent from their diets: D. dubia ate relatively more animals associated with riffle habitats; E. punctata ate relatively more pool-dwelling organisms. The greater abundance of D. dubia at our study sites is attributed to this difference in habitat preference.BARTON, D. R., et J. L. METCALFE. 1986. Life cycles, reproduction, and diets of Dina dubia and Erpobdella punctata (Hirudinea: Eropobdellidae) in Canagagigue Creek, Ontario. Can. J. Zool. 64: 640-648. Des rkcoltes semi-mensuelles (mensuelles en hiver) de mai 1982 a juillet 1983, en deux endroits du ruisseau Canagagigue, ont perrnis de dCcrire les cycles biologiques de Dina dubia et d'Erpobdella punctata. Des observations sur la reproduction ont Ct C recueillies dans le ruisseau et dans un aquarium a eau courante. La plupart des individus des deux especes font leur cycle en 1 an environ, mais quelques-uns mettent 2 ans ou plus a atteindre leur maturitk sexuelle. Les parametres fCconditC moyenne, estimCe a 138-173 rejetonsladulte, taux de croissance et taille maximale (1946 mg masse fraiche) sont plus ClevCs chez E. punctata que chez D. dubia (47-50 rejetonsladulte; taille maximale 725 mg), mais D. dubia est beaucoup plus abondant dans le ruisseau. Les deux especes se nourrissent surtout de Chironomidae et d'oligochaeta, et 1'Cventail des proies consommCes reflbe la diversite des proies disponibles. Les prCfCrences d'habitat des sangsues se refletent aussi dans leur nourriture: D. dubia consomme relativement plus de proies associCes aux eaux rapides, alors qu'E. punctata co:~somme relativement plus d'organismes d'eaux calmes. La plus grande abondance de D. dubia aux stations d'tchantillonnage est d'ailleurs due a cette diffkrences dans les prCfCrences d'habitat .[Traduit par la Revue]
