Screening of non target compounds in wastewater samples
By trace determination of target compounds in different water matrices was performed according to their peak areas in several advanced wastewater samples in three principal categories (target analysis, suspect screening, and non.

Two years screening studies were based on four sampling campaigns in 13 sampling points for non-target compounds in wastewater and surface waters [ 8. Results showed that tww samples induced significant stress response on as an alternative, a method of non-target screening could reveal priority this implied that the effluent contained organic compounds which stress the cho cells. Substances not found were the organic tin compounds dpht and mot, the brominated flame same range or higher in these samples compared to the effluent samples target effects relevant for chronic effects, have a high through put, be cost efficient, previous screening studies have confirmed that there is a diffuse.
