Micro-Chemical Characteristics of Carp Otoliths and Their Typomorphic Significance in the Evaluation of Water Quality in Lakes and Reservoirs——As Exemplified by the Baiyangdian Lake, Hebei Province and the Miyun Reservoir, Beijing
详细信息   
摘要

Trace elements in otoliths of the wild carps (cyprinoid) from the Baiyangdian Lake of Hebei Province and the Miyun Reservoir in the Beijing metropolitan were quantitatively analyzed. The contents of trace elements in otoliths of wild carps growing up in the Baiyangdian Lake are higher than in the Miyun Reservoir. The phenomenon indicates that the environment of the Baiyangdian Lake is more complex and more seriously polluted than that of the Miyun Reservoir. The concentration coefficients of trace elements in otoliths follow the increasing order of  Zn>Sr>Se>Fe>As>Ba>K>Co>Au>Na>Cr. The contents of trace elements in otoliths and water from the Baiyangdian Lake and Miyun Reservoir have a linear correlation. yes">
