CHAPTER 14 • Chemistry of Organic Toxicants in Marine Environments

to this, octyl phthalate was not found in substantial amounts at these stations, but the
highest concentration of this compound has been found in the vicinity of Balearic Islands.
In the spring of 1991, the joint Russian-Italian expedition headed by Professor
A. Gianguzza (University of Palermo) and the author of this paper started in Palermo,
and all 33 stations were within the Tirrenian Sea (Fig. 14.13).
The concentrations of organic contaminants in the Tirrenian Sea waters were
measured by means of high-resolution gas chromatography (Drs. P. I. Demyanov,
A. N. Fedotov, M. V. Lomonosov University, Moscow), and are presented in Table 14.5.
Sea waters with hydrocarbons and phthalates at most of the stations were at the
same levels, but the contents of alkanes, dibutyl phthalate and other dialkyl phthalates
were much higher at Station 1. The changes in concentrations of all the compounds
that had been found in the Tirrenian Sea waters are shown graphically in Fig. 14.14.
Drs. 1. de Domenico and G. Magazzu (Oceanography Institute, CNR, Messina) obtained the data on the contamination of the Tirrenian Sea sediments with polycyclic
aromatic hydrocarbons (PAHs), using two different standards (chrysene and crude oil).
The results obtained are presented in Table 14.6.
