The Bioconcentration of Marine debris in Pacific Garbage Patch

摘要

The toxin-containing marine pieces which are broken down from the plastics in Pacific Garbage Patch are easily eaten by primary consumers and be enriched through the food chain. So, the enrichment effect of marine debris in the patch of the primary consumer is studied in this research with the composite consideration of time and space. To the enrichment effect, the two-compartment bio-concentration model of primary consumer is constructed taking into account of the distribution of plastic garbage debris in water and biota. The result is that the increasing amount of the concentration of garbage debris in organisms is larger than that in seawater. So controlling the amount of waste which is the most fundamental measures should be implemented right now to prevent further deterioration of the situation. And dealing with the existing waste is also very necessary to prevent the further enrichment of the food chain.
