Table 5.2.1. Positions and data for the blue mussels (Mytilus edulis) sampled around Nuuk in November 1997. Concentration levels of organotin and tin (IV) in blue mussels in µg/kg^-1 (all as Sn), monobutyltin was not detected (< 0.1 µg/kg ww as Sn). The L.O.D. was estimated to be at less than 0.1 µg/kg ww (as Sn). The water content in mussel tissue was (80.2  ± 1.1) % (5 individual determinations)   Station Lat. Long.
