Abstract

Monitoring of water samples taken from some territories was carried out. So that water samples were taken from 7 different regions of the Caspian Sea and analyzed for mainly toxic organic compounds – PAHs, phenol, and its derivatives. The analyses were carried out using extremely sensitive devices such as GC-MSD gas chromatograph 6890N with a highly efficient mass-selective detector-Agilent 5975. It was determined that the investigated toxic organic compounds in the wastewaters of the Caspian Sea coast exceed the permissible limit. This fact was formed against the background of serious negative impacts on the flora and fauna of the Caspian Sea with the discharge of industrial wastewater. In water samples, 15 PAHs and 11 phenolic compounds were analyzed.
