AB  - Determining stratigraphic markers of the Anthropocene is important for 
      demarcating Global Stratotype Section and Point (GSSP). Heavy metals and 
      persistent organic pollutants (POPs) are candidate geochemical markers of the 
      Anthropocene, but no study has comprehensively evaluated temporal trends in these 
      pollutants in sediment cores globally. 454 data points for 8 heavy metals and 8 
      POPs were compiled to reconstruct their temporal trends and evaluate their global 
      consistency. The heavy metals did not increase rapidly in the 20th century, and 
      their temporal trends were locally but not globally consistent, which are not 
      suitable geochemical markers of the Anthropocene. POPs rapidly increased 
      beginning in the mid-20th century but have declined in the past decade, and these 
      data are more consistent globally. The time of the peak concentration and period 
      of rapid increase for polychlorinated biphenyls (PCBs) occur near the boundary of 
      the Anthropocene and are consistent globally. Forty-five percent of the studies 
      evaluated used only (210)Pb chronology for dating, which creates definite 
      uncertainty in the analysis. In GSSP candidate sections, PCBs could be considered 
      candidate markers of the Anthropocene.
