Sources of mercury in the Arctic
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-02)
Global and regional emission inventories of mercury are reviewed with special emphasis on the source regions with potential impact on the Arctic environment. These sources are located mostly in Eurasia and North America ...
Atmospheric sources, transport and deposition of mercury in Michigan: Two years of event precipitation
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-02)
To assess the sources, transport and deposition of atmospheric mercury (Hg) in Michigan, a multi-site network was implemented in which Hg concentrations in event precipitation and ambient samples (vapor and participate ...
Amphi-Atlantic phylogeography of direct-developing lineages of Lasaea, a genus of brooding bivalves
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-10)
Direct-developing intertidal Lasaea spp. occur in the North Atlantic as both continental margin and oceanic island populations. We conducted a molecular phylogenetic analysis of representative populations in order to test ...
