Qualitatively, this sewage differs from the sea water which produced it on various points : It is richer than the water in Organic Carbon, Organic Nitrogen, Ammonia, particulate matters, phosphorus and varied metals. However the concentration factors are not constant and they change in time. This sewage is toxic for some group of animals and this toxicity varies with the concentration but also the age of the product.
