2. 1. Riverine sources of bioreactive macroelements and their impact on bacterioplankton metabolism in a recipient boreal estuary

   Author : Ana Soares; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : Dissolved organic carbon; DOC bioreactivity; nutrient bioavailability; dissolved organic matter; bacterioplankton production; bacterial respiration; aquatic ecology;

   Abstract : The loading of terrestrially derived macroelements, such as dissolved organic carbon (DOC), total nitrogen (N), and total phosphorus (P), to inland and estuarine waters is increasing in the northern hemisphere. Thesemacroelements often limit heterotrophic bacterioplankton metabolism (production and respiration), which in turn influence food web structures, exchange of greenhouse gases between the atmosphere and aquatic systems and oxygen consumption in estuarine ecosystems.

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm bioreactors; Miljöteknik; pollution control; Environmental technology; Teknik; Technological sciences; white-rot fungi; nonylphenol ethoxylates; endocrine-disrupting activity; contaminated soil; cold-adapted organisms; kontroll av utsläpp; Biotechnology; Bioteknik; biodegradation;

   Abstract : Currently, over 100 high-volume chemicals have been classified as endocrine disrupters. One of these is nonylphenol, which was used as the model compound in this study. This substance originates mainly from the degradation of non-ionic surfactants (nonylphenol ethoxylates) which are widely used in industrial and domestic applications. READ MORE
