中文摘要：

测定了采自福建省5个地区和广东省汕头市的白鹭（Egretta garzetta）和池鹭（Ardeola bacchus）成鸟羽毛中铬（Cr）、锰（Mn）、镍（Ni）、铜（Cu）、锌（Zn）、砷（As）、镉（Cd）、铅（Pb）7种重金属元素的含量．结果：重金属在两种鹭鸟的羽毛中积累规律都为：Zn〉Cr〉Cu〉Pb〉As〉Cd．比较了武夷山、鸡屿、安海和汕头的白鹭羽毛样本的重金属的含量，结果Cr、Mn、Zn、As、Pb的含量存在显著的地区性差异，汕头地区的Cr、As含量最高而Mn、Zn、Pb含量最低；比较了武夷山和建瓯池鹭羽毛样本的重金属的含量，结果Ni和A5的含量存在显著的地区性差异，武夷山地区的Ni含量较高而舡含量较低．比较了武夷山地区池鹭、白鹭羽毛的重金属含量，Cr和As在池鹭中较高，Zn在白鹭中较高．比较了汕头地区白鹭雌雄羽毛样本，只有Cd的含量在雌性和雄性的羽毛中有显著差异．

英文摘要：

Concentrations of chromium, manganese, nickd, copper, zinc, arsenic, cadmium, and lead were determined in the feathers of adult Little Egrets （Egretta garzetta） and Chinese Pond-Heroin （Ardeola bacchus） from five rites in Fujian Province and one site in Guangdong Province. Generally in both species, the heavy metal content was Zn 〉 Cr 〉 Cu 〉 Pb 〉 As 〉 Cd. Significant between-area differences in Cr, Mn, Zn, As and Pb concentrations were found in the Little Egrets and Ni and As in the Chinese Pond-Herons. For the Little Egrets, Shantou had the higher levels of As and the lower levels of Mn, Zn and Pb. For the Chinese Pond-Herons, Wuyi Mountain had the higher level of Ni but the lower level of As. Interspecies differences were found in Cr, As and Zn levels. Chinese Pond-Herons had higher levels of Cr and As, while Little Egrets had higher level of Zn. Only Cd level differed significantly between male and female Lit-de Egrets.
