| Abstract |
Since the beginning of the sixties, benthic assemblages established on soft substrates in the vicinity, in the Cortiou cove of the big sewer of the City of Marseilles, have been studied. The noxious effects of the sewer were not longer considerable. In the seventies, a succession of catastrophic episodes linked with modifications in the nature and volume of discharged waters have conducted to the more or less marked destructuration of the original assemblages in an area of more than 30 square kilometers. The bionomical studies (and their relations with the chemistry of sediments and interstitial waters) have been conducted in 1976. Among the 40 prospected stations, six have been chosen and studied one more time in 1980 and 1986. This research has contributed to the design of the large depurator plant of the City of Marseilles and to various subsequent processes to control the effects of refuse. |
