TL;DR: A conceptual model that simulates the effects of plastic on bioaccumulation of POPs is developed and analyzed, showing that plastic with low affinity for POPs such as polystyrene will have a marginal decreasing effect on bio Accumulation, governed by dilution.
Abstract: It has been hypothesized that persistent organic pollutants (POPs) in microplastic may pose a risk to aquatic organisms. Here we develop and analyze a conceptual model that simulates the effects of plastic on bioaccumulation of POPs. The model accounts for dilution of exposure concentration by sorption of POPs to plastic (POP “dilution”), increased bioaccumulation by ingestion of plastic-containing POPs (“carrier”), and decreased bioaccumulation by ingestion of clean plastic (“cleaning”). The model is parametrized for the lugworm Arenicola marina and evaluated against recently published bioaccumulation data for this species from laboratory bioassays with polystyrene microplastic. Further scenarios include polyethylene microplastic, nanosized plastic, and open marine systems. Model analysis shows that plastic with low affinity for POPs such as polystyrene will have a marginal decreasing effect on bioaccumulation, governed by dilution. For stronger sorbents such as polyethylene, the dilution, carrier, and c...

TL;DR: The distribution of heavy metals in water and fish from Fayoum Governorate (Egypt) was studied in samples collected throughout two successive years (1997/1998 and 1998/1999). Water from Lake Qarun, a private fish farm and Sanhour River was found to contain heavy metals at concentration levels lower than those found in fish from the first two ecosystems as mentioned in this paper.

TL;DR: Under bloom dilution, as algal biomass increases, the concentration of mercury per cell decreases, resulting in a lower dietary input to grazers and reduced bioaccumulation in algal-rich eutrophic systems, and Bloom dilution may provide a mechanistic explanation for lower CH3Hg+ accumulation by zooplankton and fish in alGal-rich relative to algal
Abstract: Mercury accumulation in fish is a global public health concern, because fish are the primary source of toxic methylmercury to humans. Fish from all lakes do not pose the same level of risk to consumers. One of the most intriguing patterns is that potentially dangerous mercury concentrations can be found in fish from clear, oligotrophic lakes whereas fish from greener, eutrophic lakes often carry less mercury. In this study, we experimentally tested the hypothesis that increasing algal biomass reduces mercury accumulation at higher trophic levels through the dilution of mercury in consumed algal cells. Under bloom dilution, as algal biomass increases, the concentration of mercury per cell decreases, resulting in a lower dietary input to grazers and reduced bioaccumulation in algal-rich eutrophic systems. To test this hypothesis, we added enriched stable isotopes of Hg to experimental mesocosms and measured the uptake of toxic methylmercury (CH3200Hg+) and inorganic 201Hg2+ by biota at several algal concentrations. We reduced absolute spike detection limits by 50–100 times compared with previous techniques, which allowed us to conduct experiments at the extremely low aqueous Hg concentrations that are typical of natural systems. We found that increasing algae reduced CH3Hg+ concentrations in zooplankton 2–3-fold. Bloom dilution may provide a mechanistic explanation for lower CH3Hg+ accumulation by zooplankton and fish in algal-rich relative to algal-poor systems.

TL;DR: The bioaccumulation of polychlorinated biphenyl (PCB) congeners and some other chlorinated organics in the Lake Ontario ecosystem has been studied in this paper.
Abstract: The bioaccumulation of polychlorinated biphenyl (PCB) congeners and some other chlorinated organics in the Lake Ontario ecosystem has been studied. In addition to the classical biomagnification of PCBs and some of the other organics, the chlorine content of the PCBs was observed to increase with trophic level. Most of the differential PCB fractionation seemed to occur at the lower end of the food chain (water to plankton to mysid). At the higher trophic levels (mysid to smelt to salmonid), the PCBs seemed to be distributed as a uniform composition mixture. The bioaccumulation factor of these hydrophobic organics increased linearly with octanol-water partition coefficient of the chemicals at all trophic levels. The environmental bioaccumulation of these chemicals in salmonids was higher than that predicted from bioconcentration from water alone, showing that contaminated food is a major source of these chemical residues in fish.
