Abstract

Bioaerosols were collected between April and November 2015 on land (Gdynia) and at sea (Southwestern Baltic), using six-step microbiological pollutant sampler. It was determined that picoplanktonic cyanobacteria of the genus Synechococcus, Synechocystis, Aphanocapsa, Aphanothece, Microcystis, Merismopedia, Woronichinia and Cyanodictyon were the most commonly found in aerosols both over land and at sea. Chlorophyta were also numerous (Chlorella vulgaris, Stichococcus bacillaris), as were Bacillariophyta and Ochrophyta (Phaeodactylum sp., Navicula cf. perminuta and Nannochloropsis cf. gaditana). As primary production and phytoplankton concentration in sea water grew, so did the diversity of the microorganisms identified in bioaerosols. Over the sea cyanobacteria and microalgae occurred more often in large aerosols (> 3.3 μm). Over land they were mainly the components of smaller particles. In respirable particles species both capable of producing harmful secondary metabolites and potentially toxic ones were identified. We assume that bioaerosols pose the actual threat to human health in Baltic Sea region.
