AB δ15N concentration can reveal the anthropogenic pollution of an ecosystem. To study this pollution level, thisisotope can be analyzed from water or animal tissue. Sewage pipes pour anthropic waters, rich in δ15N, to thesea. In the sewage pipes surroundings live several organisms, like the cnidarian Anemonia sulcata (Pennant,1777). As anemones have zooxanthellae, they incorporate nitrogen from the environment. To test for the possible effects of wastewater effluents on the coastal ecosystem through the content of the isotope δ15N, A. sulcataspecimens were collected near a sewage pipe in North Tenerife (Spain), in contiguous zones to look for a δ15Ngradient. The obtained results show that there is a gradient of δ15N concentration, and the highest levels werefound nearest the sewage pipe (mean = 5 δ15N ‰) and the lowest in the control zone (mean = 3.26 δ15N ‰).Being so, A. sulcata has proven to be a sensitive organism whose δ15N concentration can be used as bioindicatorfor pollution and human involvement in the ecosystem in which it lives
