abstract: In 2010–2016 open Black sea water concentration of ΣPCB₆ varied in the range from 0.05 to 5.04 ng∙l⁻¹, ΣDDT — from 0.05 to 4.68 ng∙l⁻¹. In 2017, 4 times higher concentration of ΣPCB₆ and 1.8 times — ΣDDT was observed comparing with the period 2016. On average, the concentration of PCBs in the coastal regions of the Crimea exceeded the DDT content. The PCBs congeners concentration in the surface layer of offshore Crimea bottom sediments varied in the range 0.45–1.76 ng∙g⁻¹ dry weight and depended
