TL;DR: Risks anticipated from contaminants in a rapidly changing environment and the research required to understand and predict how on-going and future climate change may alter risks from chemical pollution are discussed.

TL;DR: This work synthesizes recent experimental and field studies providing strong empirical evidence that cyanobacterial nitrogen is efficiently assimilated and transferred in Baltic food webs via two major pathways: directly by grazing on fresh or decaying cyanobacteria and indirectly through the uptake by other phytoplankton and microbes of bioavailable nitrogen exuded from cyanob bacterial cells.

TL;DR: The embryonic development of the deposit-feeding Baltic amphipod Monoporeia affjnis (Lindstrom) was studied from fertilization to hatching and the variable is suggested to be particularly toxicant-sensitive and by analysing the number of malformed embryos of M. affinis an early warning of affected populations could be provided.

TL;DR: Results indicate that Cd, Zn, and Cu are comparatively unavailable after oxygenation of the metal sulfides, suggesting that other metal ligands, in addition to AVS, are important for metal bioavailability and toxicity in anoxic and suboxic environments.
