Distribution of phenol derivatives by river waters to the marine environment (Gulf of Gdansk, Baltic Sea)

The aim of this study from 2020 was to identify the role rivers, including those with low water flow and a constant inflow bisphenol A (BPA), 4-tert-octylphenol (4-t-OP) 4-nonylphenol (4-NP) marine environment. Water samples were collected small rivers flowing into Gulf Gdańsk Vistula River. Final assays performed using high-performance liquid chromatography fluorescence detector (HPLC-FL). highest concentrations phenol derivatives found in summer, most likely due higher consumption products containing derivatives. Another factor may be type development catchment area. measurements did not exceed PNEC, though does mean that amounts introduced by can ignored. Mean loads xenobiotics sea via have been calculated as over 320 kg y-1 BPA about 55 4-t-OP 4-NP each.
