HUSHÅLLENS ANDEL AV FÖRORENINGAR TILL RYAVERKET- TILLFÖRSEL FRÅN TVÅ BOSTADSOMRÅDEN I GÖTEBORG / Priority Pollutants, Heavy Metals and Main Constituents in the Domestic Sewage from two Residential Areas in Gothenburg
A program to chart the sources for undesirable contaminants in the influent water to Ryaverket was started in 1988. Stage one was a study of domestic sewage. Two residential areas in Gothenburg were chosen and sewage water was collected on four occasions during the year, as 24 h flow proportional samples. These were analysed together with the corresponding influent samples at Ryaverket, for 130 different parameters including priority pollutants. The results were used to estimate the total domestic discharge for the catchment area served by the Ryaverket waste water treatment plant. The total domestic load was estimated to 50-60 % for COD and BOD, 60-75 % for phosphorus and nitrogen, ca 30 % for heavy metals, 20-70 % for napthalene, 2-5 % for p-nonylphenol, 40-70 % for di-(2-ethylhexyl) phtalate and 0-5 % for trichloroethene of the total quantities in the influent to Ryaverket. “Complete abstract not presented.”
