Triazine-type herbicides (atrazine, simazine, terbuthylazine, DEA - deethylatrazine) were analysed in the surface waters of the Baltic Sea off Poland in September 1995 and April 1997. Total concentrations varied from 14.7 to 30.0 ng dm-3 in 1995 and from 8.5 to 12.7 ng dm-3 in 1997. Concentrations in offshore samples were much smaller than in inshore ones (15.6š2.2 vs 23.5š4.8) in 1995, while no differences were found in 1997 (9.2š1.8 vs 10.1š2.3). This was attributed to the increased input of triazines to the Baltic Sea with river run-off following the summer application of these substances in agriculture. The ratios of concentrations of individual compounds indicate that terbuthylazine is present in similar proportions in the Pomeranian Bay and the Gulf of Gdansk (21% vs 20%), despite the ban on the use of atrazine and simazine in Germany imposed in the early 1990s. Similar DEA-to-atrazine indices in both the Pomeranian Bay and the Gulf of Gdansk (1.20š0.22 vs1.31š0.25) support the inference that the run-off from the rivers Vistula and Odra contributes to the distribution of triazines in the surface waters of the southern Baltic.
