Abstract
Concentrations of technical 4-nonylphenol, 4-n-octylphenol, and 4-tert-octylphenol were investigated in surface water and sediment samples of four sites located at the fragmented landscape of the Atlantic rainforest in the region of São Paulo, Brazil. Background contamination was determined at a site located in the Morro Grande forest reserve. Total alkylphenol concentrations in sediments of the remaining sites (Takimoto 1, Takimoto 2, Pedro) and Morro Grande generally ranged between 1 and 10 µg kg-1 dw with 4-tert-octylphenol being the dominant alkylphenol. Because 4-tert-octylphenol concentration patterns at Takimoto 2, Pedro, and the Morro Grande forest reserve were found to be quite similar, 4-tert-octylphenol contaminations at these locations was considered as ubiquitous background concentrations. In contrast, Takimoto 1 showed significantly higher 4-tert-octylphenol sediment concentrations. This input of 4-tert-octylphenol at Takimoto 1 was assumed to originate from adjacent fields, which were extensively used for agriculture. Analysed alkylphenols were not detectable in water samples
