The authors are thankful to Dr. A. Subramanian (CMES, Ehime University) for critical reading of the manuscript. We also thank Prof. Zongguo Huang of the Third Institute of Oceanography, State Oceanic Administration, China for helping us to collect the bird eggs from Xiamen and Quanzhou. This project was funded by the Hong Kong Research Grants Council CityU 1112/02M, and the Area of Excellence Scheme under the University Grants Committee of the Hong Kong Special Administration Region, China (Project No. AoE/P-04/2004). This work was undertaken during tenure of a City University Postgraduate Studentship and a Fellowship under the “21st Century COE Program” from the Ministry of Education, Culture, Sports, Science and Technology of Japan to JCWL.

N2 - Concentrations of total polybrominated diphenyl ethers (PBDEs) in Ardeid eggs from Hong Kong, Xiamen and Quanzhou in south China ranged from 140-1000, 30-550 and 140-380 ng g-1, lipid wt., respectively. There were spatial and interspecies variations in the abundance and congeneric profiles of PBDEs. The different congeneric profiles observed among the study sites may be associated with the developmental phases of the cities, as well as a possible consequence of debromination of BDE209. Marked concentrations of higher-brominated diphenyl ethers (BDEs 183, 196, 197, 206, 207 and 209) were detected in the egg samples from all sites, probably indicating uptake of BDE209 by top predators, and that there is widespread occurrence of BDE209 in south China. Comparisons of egg concentrations of BDEs 47, 99, 153 and 209 with tentative critical concentrations for neurobehavioral effects and oxidative stress indicated some potential risks for BDE99 and BDE209 in the Ardeid populations.
