PBDEs and HBCD in sewage sludge and river sediments in the Czech Republic: A 3-year survey (2006-2008)

Popis výsledku v původním jazyce

During a 3-year survey (2006?2008) 15 monitoring points of WWTP sludge and 13 monitoring points of river sediments were regularly investigated in October and November each year within the Czech Republic (CR) locations. Target brominated flame retardants(BFRs) includes polybrominated diphenyl ethers (PBDE congeners 28, 47, 49, 66, 85, 99, 100, 153, 154, 183, and 209) and hexabromocyclodecane (HBCD). The obtained mean values of stabilized WWTP sludge for the most abundant congeners BDE 209, BDE 47, BDE 99 and HBCD in 2006 were 255.7, 30.7, 29.8 and 12.2 ?g/kg dw, respectively. The major changes were detected in 2008 in content of BDE 209 (decrease of mean value to 54.4 ?g/kg dw) and in content of HBCD (increase mean value to 173.8 ?g/kg dw) in comparison to 2006. The mean value of river sediments shows almost 97% decreasing of total content BFRs in sludge to compare years 2006 and 2008. Generally, BDE 209 decreased from 19.1 to < 1.2 ?g/kg dw. HBCD content in median value still was not
