Abstract: Speciation characteristics of fifteen heavy metals in seventeen surface sediments from Jiulong River was analyzed using the modified BCR protocol and dilute HNO3method, respectively. The results of the modified BCR protocol showed that most of the elements (Fe, Ni, V, Tl, Ba, Sb, Ga, Cr and Sr) existed mainly in residual fractions, and extractable fraction was dominant for Mn (83.8%), followed by Cd, Pb, Zn, Co and Cu (80.0%, 75.5%, 74.3%, 70.8% and 57.7%). The results of dilute HNO3method showed that the proportions of the dilute HNO3-extractable fractions of Pb, Mn, Cd, Co, Zn and Cu were higher (70.4%, 65.4%, 58.7%, 48.4%, 44.5% and 45.5%). The assessment results of RSP (ratio of secondary phase to primary phase) indicated that Pb, Mn, Cd, Co, Zn and Cu in surface sediments of Jiulong River had higher ecological risks. Both extraction methods had merits and demerits respectively. In general, the dilute HNO3method is enough to analyze the bioavailability and ecological risk of heavy metals in sediments. © 2017, Science Press. All right reserved.

华侨大学化工学院 胡恭任。刚开始接触觉得人还不错,相处久了就会发现真不是那回事,做的都是十几年的课题,拼了命的让学生发文章,在办公室还弄个打卡,感觉像管高中生一样。学生有悖他们的意思,就是冷嘲热讽,在组会上让学生下不了台。据说他带的学生,毕业后就没几个跟他们再有联系的。他老婆也在化工学院,他们是夫妻档。这两夫妻都是心理变态。
