dw). On the other hand, the least removed compound in both the long-tailed duck and the razorbill was 4-t-OP. The removal of phenol derivatives from claws in both bird species was at the same level. However, 4-NP concentrations were found to be statistically significantly higher in razorbill remiges compared to those of the long-tailed duck (p < 0.05). Comparison of concentrations in the remiges of the long-tailed duck and the razorbill, moulted in two different environments with different levels of pollution and distances from sources, indicated that the Baltic Sea is approximately 3 times more polluted with 4-NP than the marine areas of the Russian Arctic. This demonstrates the potential for the use of 4-NP and remiges as indicators of environmental pollution with phenol derivatives.
