1977: Panton Hill (Vic). DDT and Dieldrin residues in Kookaburras.

p574 “In another early study, Parry (1973) reported DDT contamination in Laughing Kookaburra (Dacelo novaeguinea). The specimens, collected from the inner Melbourne suburb of Brunswick and from Panton Hill just outside of Melbourne revealed low concentrations of DDE in liver, muscle and brain and dieldrin in liver. Insufficient data was available to predict whether these concentrations had an adverse effect on species survival. However, the author commented on the longevity of kookaburras (between 12 and 25 years) and emphasised the long period over which production could be affected.”
