[Monitoring of polycyclic aromatic hydrocarbons in the aquatic environment]

A monitoring system for the carcinogenic PAH is proposed, based on the data-analysis of their dissemination and distribution in water bodies of the Estonian SSR (with benz(a)pyrene as an indicator of the PAH pollution) using bottom sediments as test-objects. A control system for various kinds of water bodies and a system to evaluate a degree of PAH pollution of the water bodies have been proposed. The use of bottom sediments as a test-object makes this system universal, simple and easily available for investigations.
