Figure 1.

Figure 1 is a graphical representation plotting noncancer incidence (y-axis) across PCB dose (milligrams per kilogram day; x-axis) for three subpopulations of Hudson River fish consumers: twice per year, twice per month, and twice per week.

Noncancer PCB dose–response relationship corresponding to a 50% decrease in immunoglobulin M. Curved (black) solid   line=median. Curved (black) dashed   line=arithmetic   mean. Surrounding (dark gray) area=95% confidence interval. Vertical (colored) dashed lines=95% confidence intervals of average daily doses (mg/kg-d) for three subpopulations: Upper Hudson anglers and their family members consuming fish at frequencies of a) twice per year, b) twice per month, and c) twice per week during the 2004–2009 timeframe.
