| Contents Notes | Four twelve-foot cores and one eighteen-foot core were taken near Lewes, Delaware. Samples were taken at two-foot intervals down the core beginning at two feet below land surface. The samples were analyzed for zinc, copper, chromium, iron lead and cadmium. The levels of lead and cadmium were below the level of detectability by the methods used (i.e. less that 1 ppm in the sediment sample). Zinc showed a slight increase in average concentration with increasing depth. Copper and cadmium showed no significant changes in depth. There appears to be no significant difference in the metal concentrations between the <63 and >63 fractions. |
