The effects of rodenticide residues deposited in eggs of Tyto alba to eggshell thickness
The deposition of anticoagulant residues in the eggs of barn owls, Tyto alba by assessing eggshell thickness were investigated in oil palm plantations. Three study plots were set aside; one plot each baited with chlorophacinone and bromadiolone, respectively and the third was left unbaited. Four...

| description | The deposition of anticoagulant residues in the eggs of barn owls, Tyto alba by assessing eggshell thickness were
investigated in oil palm plantations. Three study plots were set aside; one plot each baited with chlorophacinone and
bromadiolone, respectively and the third was left unbaited. Four baiting campaigns were conducted on the rodenticide
designated plots, coinciding with the breeding seasons of T. alba. High performance liquid chromatography (HPLC)
showed that 29.73% (n=37) and 5.35% (n=56) of addled eggs collected from rodenticide treated plots contained
bromadiolone and chlorophacinone, respectively, with mean concentration of residues from 0.009 to 0.031 µg/g wet
weight. None of the addled eggs (n=28) collected from the unbaited plot contained bromadiolone or chlorophacinone
residues. The detection of rodenticide residues in both albumen and yolk indicated high risk of secondary poisoning to
both compounds. However, low levels of residues detected have no effects on shape of egg, eggshell mass or thickness. |
