|Abstract:||The occurrence and distribution of the major surfactants e LAS, AES, APEOs and AEOs e and their degradation intermediates e SPCs, AP
and APECs e in a marine-estuarine environment at Spain are presented. Results show that their concentration in surface sediments is clearly
correlated with their usage and the existence of wastewater discharges. The degradation processes appear to lead to the formation of SPCs in the
case of LAS, and to the shortening of the average ethoxylated chain length in the case of NPEOs, AEOs and AES. Vertical profiles for AEOs and AES are reported for the first time and present the highest values nearest the surface, followed by a sharp decrease with depth for all surfactants, as well as the appearance of degradation intermediates in deeper sedimentary layers. Shorter LAS homologues and SPCs tend to be present in pore water while strongly non-polar intermediates like NP are firmly attached to the sediments.|
The presence of vertical and longitudinal distribution of the major surfactants and their intermediates in sediments and pore water is reported for the first time.
