title: NUMERICAL MODELING OF THE FIELDS OF POLYCHLORINATED BIPHENYLS IN THE BLACK SEA
abstract: A mathematical three-dimensional model was developed by combining a physically complete block of circulation with modules of transport and transformation of detritus and polychlorinated biphenyls (PCBs). This z-coordinate model has a horizontal resolution of 5 × 5 km, 45 vertical levels, and a step of 5 minutes. The model considers gravitational sedimentation and decomposition of detritus, as well as its deposition and erosion on the bottom. To calculate the transport and transformation of PCBs
