Abstract [en]

The purpose of this study was to analyze the amount of phthalates in the wastewater in Umeå and if possible determine if specific areas in the city contributes in a higher extent to the amount of phthalates in the influent in the municipal wastewater treatment plant (WWTP), Ön. Wastewater samples were collected at 6 sampling points, i.e. pump stations, directly connected to Ön’s WWTP. The result showed that the sampling point U9 contributed to the largest amounts of phthalates in the influent to Ön’s WWTP, over 47 %. However, to U9 are more than 60 % of the total registered inhabitants in Umeå connected. 4 out of 6 sampling points had a correlation between the number of registered inhabitants in the area and the phthalate amount leading to a conclusion of diffuse leakage from building materials. One sampling point, T5, with only 0,03 % of the total amount of registered inhabitants to Ön’s WWTP contributed with almost 12 % of the total amount of phthalates in the influent. Leading to the conclusion that the high amount of phthalates at T5 can be caused by a point source. There is a difference in amounts of phthalates in the wastewater from different areas in Umeå. Mainly caused by the number of inhabitants but also point sources. The rate of reduction of phthalates at Ön’s WWTP was more than 92 % for di (2-ethylhexyl) phthalate (DEHP), diisodecyl phthalate (DIDP) and diisononyl phthalate (DINP).
