“…concentrations in the whole-organism soft tissues relative to pre-operational concentrations (Table 18). Concentrations of both Zn and Pb in bivalve tissues tended to be higher closer to the Twin Lakes outfall (Asmund et al 1991). A similar relationship was found in mussels (Mytilus edulis) samples in the vicinity of mines at Maarmorilik and Ivittuut (Greenland), although the concentrations of Zn and Pb were generally lower at Nanisivik (Asmund et al 1991).…”

“…During 17 years of mine operations a total of 500,000 tons per year of metal-rich particulate tailings were discharged into the local fjord system. The tailings consisted of pyrite, low grade zinc, and lead ore with traces of heavy metals (Loring & Asmund 1989;Asmund et al 1991;Josefson et al 2008). The capitellids available to me were taken as part of an environmental monitoring effort in 1976.…”

Capitella capitata (Fabricius, 1780), the type species of the genus, was originally described from the SW coast of Greenland; however, current definitions of the species are largely based on Eisig (1887), who described specimens from Naples on the Mediterranean coast. Eisig’s excellent account of the morphology of a sexually dimorphic species has subsequently been applied to specimens collected from worldwide locations. C. capitata was considered cosmopolitan in its distribution until J.P. Grassle and others identified numerous sibling species in laboratory culture. A large collection of Capitella from locations along the W, SW, and SE coasts of Greenland was provided by the Zoological Museum, University of Copenhagen (ZMUC). The collections included about 680 specimens with distinctive prostomial, thoracic, and setal morphology that differs from the typical depiction of the species in most faunal accounts. A neotype was selected from an excellent collection of approximately 250 specimens from Mârmorilik on the Affarlikassâ Fjord on the inner Uummannaq Fjord system, north of Disko Bay. All available collections from the ZMUC are believed to belong to the same species, which is here considered to be Arctic and subarctic in distribution. Additional material from the Alaskan Arctic supports this hypothesis. The Greenland species has a short, cup-shaped, wider-than-long prostomium joined to a narrow peristomial ring that is retracted slightly into setiger 1. In most specimens, the first four thoracic setigers gradually increase in size, with setiger 4 being the largest thoracic segment, and then decrease over the next five setigers, with setiger 9 being smaller than subsequent anterior abdominal segments. The thoracic region is thus markedly distinct visually from the abdominal region. Setigers 8–9 typically lack fascicles of notosetae, but 80% of the specimens examined have genital spines and most have copulatory organs that are secretory in nature: they contain numerous small secretion granules but no sperm. Many of these specimens have eggs and larvae within their tubes, suggesting functional hermaphroditism. The present redescription of C. capitata serves to establish a baseline against which the many known but undescribed species can be compared. Previous accounts of C. capitata based on the Eisig concept and largely from boreal and temperate localities should be reevaluated.

“…In addition, two other closed STD operations, the Kitsault molybdenum mine (British Columbia, Canada) and the Black Angel Mine (Greenland), have been widely discussed in the literature. While the Island Copper and Kitsault mines did not seem to have significant long-term ecological impacts (e.g., Burd 2002), the adopted STD system at the Black Angel Mine caused contamination of the receiving fjord (Asmund et al 1991;Larsen et al 2001;Loring and Asmund 1989;Perner et al 2010). Most STD operations that started in the early 1970s are now closed.…”

With increasing metal prices and declining ore grades, new mines are getting larger and mine waste disposal and management have become more difficult, particularly from an environmental perspective. While technologies keep on improving, the available space for terrestrial mine waste disposal is limited. Thus, several coastal countries still consider deep-sea tailings placement (DSTP) as a viable option. This brief review compares the environmental impacts of DSTP versus on-land disposal and suggests several factors to consider in selecting the most suitable options for mine waste disposal.
