Muscles and livers of herring gulls (Larus argentatus) found in the coastal area of the southern Baltic Sea were tested for the presence of hexabromocyclododecane (HBCD) isomers. They were detected in the muscles (ΣHBCD = 42.82 ± 30.65 ng g−1 l.w

Our review of the literature showed that since the beginning of the socio-economic transformation in Poland in the 1990s, the downward trend in Hg emissions and its deposition in the southern Baltic Sea was followed by a simultaneous decrease in Hg l

The diastereoselective synthesis of 3,5-disubstituted 1,4-oxazin-2-ones, the valuable intermediates on the route to tetrahydroisoquinoline derivatives, was based on the Petasis reaction in which (R)-(−)-N-benzyl-2-phenylglycinol was used as the ami

Mercury enters the body of seabirds in its most toxic organic form, i.e. methylmercury, mainly via the alimentary tract. Inside the body, mercury is transformed into less toxic forms and accumulates in the internal organs. The process of mercury remo

The main aim of the research was to analyse the variability of the beach litter items, both in terms of categories and top items collected on the southern Baltic coast, based on a 5-year series of data. Research on beach litter collected in 15 sectio

The presence of persistent organic pollutants in the environment manifests itself most strongly in the marine trophic chain, where the highest link is comprised of seabirds. At the same time, seabirds are excellent indicators of contamination in thei
