Food chain sources of polychlorinated dioxins and furans to great blue herons (Ardea herodias) foraging in the Fraser River Estuary, British Columbia / A. Harfenist ... [et al.].: CW69-5/169E-PDF
"Polychlorinated dibenzodioxin (PCDD) and polychlorinated dibenzofuran (PCDF) levels in the prey of Great Blue Herons (Ardea herodias) foraging on the Fraser River estuary tidal flats were determined in 1991. Observations of herons foraging at Iona and Westham Islands showed that starry flounder (Platichthys stellatus) and Pacific staghom sculpin (Leptocottus armatus) were the major prey species throughout the year.
