    Sammanfattning : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.

    Sammanfattning : The applicability of one selected method for indirect measurement of vitellogenin (Vtg) in fish plasma based on the quantification of alkali-labile phosphates (ALP method) to assess estrogenicity in water was investigated. The ALP method applied in this investigation was originally developed with Carassius carassius (Crucian carps). LÄS MER
