| 520 | |a"In 1982, a survey of polychlorinated dibenzo-p-dioxin (PCDD) and polychlorinated dibenzofuran (PCDF) levels in Canadian wildlife revealed that Great Blue Heron (Ardea herodias) eggs from a colony in the Fraser River estuary contained unusually high levels of PCDDs (Norstrom and Simon 1983). In this note, we report the results of studies undertaken in 1983-87 to measure PCDD and PCDF levels in heron eggs from several colonies along the Strait of Georgia and to determine their effect on Great Blue Heron reproductive success"--Introd. |
