Tees Estuary

In the UK estuaries, NP and APEO were only detected in two out of the nine investigated areas. The highest estuarine water concentrations were found in the Tees estuary, as was the case in the preceding study. The majority of these APEO were present in the particulate phase 075%). 

Of nine estuaries investigated in England by Blackburn et al., only the sediments from the highly industrialised Tees estuary contained detectable concentrations of NP and A9PEOi+2 [12]. In this estuary, also the highest APEO metabolite concentrations in water were found. GC-MS analysis showed maximum sediment concentrations of 1.7 pgg-1 NP and 3.6 pg g-1 A9PEOi+2. 

In another study on the Tees estuary, flounder tissue concentrations were reported in the range of 0.030-0.180 xg A9PE0 g-1 wet weight, while A9PEO1 was not detected. In another estuary, NP was detected in three out of six fish tissues at levels between 0.005 and 0.055 xg g-1 wet weight. A9PEO1 was observed in five out of six samples in the range of...

Three minerals (montmorillonite, aluminium oxide and kaolinite) of known particle size and specific surface areas (Zhou et al., 1994) and a sterilised silty clay loam (Champaign, USA) were used as sorbents, along with suspended particulate matter (SPM) collected in polythene carboys from several sites in the Tees Estuary, UK. SPM was collected by high speed continuous flow centrifugation and stored in O.IM NaHCOj at 4 °C. Traces of organics were removed from the three minerals by washing with 0.01 M NaOH.
