— Buccinum undatum from the strait Velikaya Salma of the White Sea. A — male; B — female without imposex; C, D — female with imposex at the stage 1a (D — enlarged); E, F — females with imposex at the stage 2a. Arrows indicate penis.

Anomalies in female reproductive system
(imposex) were recorded in populations of Buccinum
undatum and Nucella lapillus in the White and
Barents seas. For Buccinum cyaneum from the Barents
Sea the anomalies in reproductive system were not
found. 7.7% of females of Buccinum undatum from
the White Sea had imposex in 1976, and 6.5% in 2005;
in the Bar...

... The tributyltin and triphenyltin toxic effects on various hydrobionts are described in sufficient detail (WHO, 1990;de Castro et al., 2019;Su et al., 2013). The organotin compounds are classified as endocrine disrupting compounds that cause disturbances in the reproductive systems of gastropods, known as imposex (Horiguchi, 2009), and other mollusks (de Carvalho Oliveira and Santelli, 2010;Dgebuadze and Kantor, 2006;Lopes-dos-Santos et al., 2014;Pagliarani et al., 2013). ...
Results of organotin and heavy metals pollution study of bottom sediment within three key areas in the Eastern Gulf of Finland (Baltic Sea) in the vicinity of Gogland and Moschny Islands and Vyborg Bay sampled during two seasons of 2017 and 2018 are presented.
The studied bottom sediments contain organotin compounds in amounts (∑OTs from 5.7 to 123 ng/g) exceeding the permissible international standards, which can have a toxic effect and lead to pathological changes of aquatic organisms. The tributyltin was the prevail component of organotin compounds in bottom sediments in 2017, which high content (average 6.3 and 30 ng/g for Moschny and Gogland islands respectively) and low degradation coefficient (BDI: 0.1–0.8) indicate a permanent source of pollution. But the 2018 samples show an increase in BDI up to 1.7–3.3 that reveals the degradation of tributyltin over the annual period. But further monitoring of environmental pollution in the study areas is obviously necessary in view of the potential impact of these components on the irreversible change in the environmental situation for the entire Baltic region.
Annotated check-list of shell-bearing Gastropoda of Murman Coast (Barents Sea Coast of Kola Peninsula) is presented. Based on original material collected in 1996-2013 and literature data 148 species are recorded for the region. Nine species: Skenea rugulosa (G.O. Sars, 1878), Aclis sarsi Dautzenberg et Fischer, 1912, Admete clivicola Høisaeter, 2010, Nassarius incrassatus (Strøm, 1768), Raphitoma leufroyi (Michaud, 1828), Taranis moerchi (Malm, 1861), Ondina divisa (J. Adams, 1797), Menestho albula (Fabricius, 1780), Bogasonia volutoides Warén, 1989 were absent in previous reviews of Russian molluscan fauna. Three species with unclear taxonomical position are listed: Skenea cf. trochoides, Omalogyra cf. atomus and Chrysallida sp. A majority of species found in Murman waters have a boreal distribution and are typical for northern European fauna. References to previous studies based on material from Murman Coast as well as original records are listed for each species, some remarkable species are depicted and discussed.
