1. 1. Ecological and physiological aspects of contaminant accumulation and transport by the filter-feeding mussel, Mytilus edulis

   Författare :Mikael Björk; Jussi Kukkonen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : This thesis examines the influence of food availability on the bioaccumulation kinetics and the transport of hydrophobic organic contaminants (HOCs) by the Baltic Sea blue mussel, Mytilus edulis. In laboratory studies, food availability was found to significantly modify the rate of physiological processes involved in filter-feeding. LÄS MER

   Sammanfattning : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bio­availability and environmental transport of the POPs. LÄS MER
