| mercury concentrations in eggshells of the southern ground-hornbill (bucorvus leadbeateri) and wattled crane (bugeranus carunculatus) in south africa. | in this study, wild hatched eggshells were collected from the nests of threatened wattled crane and south ground-hornbill in an attempt to determine their total hg concentrations. a total of fourteen eggshell samples from both bird species were collected from different study areas in the mpumlanga and kwazulu-natal provinces of south africa. the eggshells were acid digested under reflux and their total hg concentrations were determined using cold-vapour atomic absorption spectrophotometry (cv-aa ... | 2015 | 25600716 |
| polybrominated diphenyl ethers (pbdes) in eggshells of the southern ground-hornbill (bucorvus leadbeateri) and wattled crane (bugeranus carunculatus) in south africa. | this study was undertaken to assess the levels of eight pbde congeners, namely: pbde-17, 47, 100, 99, 154, 153, 183 and 209 in eggshells of southern ground-hornbill (sgh) bucorvus leadbeateri and wattled crane (wc) bugeranus carunculatus obtained from different nesting sites within the eastern savanna of limpopo province and the midlands of kwazulu-natal, respectively. analyses were performed using gas chromatography–mass spectrometry employing the electron impact ionization technique. the resul ... | 2015 | 25463252 |
