TABLE 2.
Concentrations of metals in eggs collected in 2012 from the New York / New Jersey Harbor estuary. Given are means ± SE. Comparisons are made with Kruskal-Wallis 1-Way ANOVA, yielding an X2 statistic. Duncan letter groupings on log transformed data, different letters indicate significant differences. All values are in ng/g (ppb dry weight.) NS = Not significant
