A long term effect was detected on different animal groups. Oligochaete had a long body, therefore the feeding was possible under "oil film" in the sediment and the respiration over the film, from the water body. That was the reason why they did not indicate the oil pollution. The predator Chironomid larvae, like Tanypus punctipennis, Procladius choreus and Cryptochironomus redekei were not sensitive to the oil pollution. Polypedilum scalaenum, a phytophagous species was good to indicate the oil pollution. Deformities were not detectable on the organs of the Chironomid larvae.
