摘要

这篇手稿提出了世界范围内收集的硬骨鱼中铅(Pb)含量的最大综述。对特定鱼种进行铅分析,并利用粮食及农业组织的地理捕鱼区进行定位。数据集根据每个队列中分析的数量进行扩展,导致肌肉和肝脏的铅浓度分别为22190和5954。描述性和比较性统计表明,这一编年史对研究大西洋、印度洋、太平洋和地中海盆地的硬骨鱼中铅含量的差异是有用的。不同组织的研究表明,在全球和区域尺度上,污染栖息地对铅代谢积累的影响。所有混合物种的肌肉和肝脏铅含量在0.1 ppm(湿重)以上显著相关,表明超过这个阈值,肝脏代谢可能无法有效平衡铅的吸收和排泄,铅更容易在两个组织中积累。本综述为监测环境政策对鱼类生物指标的影响,研究不同生境和生物因子对环境铅胁迫的种间和种内反应奠定了基础。

Lead abundances in bony fish from the world oceans: significance for contaminated marine habitats and environmental policies
This manuscript presents the largest review of lead (Pb) content in bony fish collected worldwide. Lead analyses are assigned to specific species and localized using the Food and Agricultural Organization geographical fishing zones. The data set is expanded according to the number of analyses in each cohort leading to a record of 22190 and 5954 Pb concentrations for muscle and liver, respectively. Descriptive and comparative statistics demonstrate the usefulness of this chronicle to examine Pb content differences in bony fish from the Atlantic, Indian, Pacific oceans, and basins of the Mediterranean Sea. Investigation of distinct tissues are indicative of contaminated habitat imprints on metabolic Pb accumulation at global and regional scales. Muscle and liver Pb content from all mixed species are significantly correlated above 0.1 ppm (wet weight) suggesting a threshold above which liver metabolism may not efficiently balance uptake and excretion of Pb that accumulates more readily in both tissues. This review constitutes a prerequisite to monitor the effect of environmental policies on fish bioindicators, and to examine interand intraspecies responses to environmental Pb insult according to various habitats and biological factors.

期刊介绍: Created in 1835 by physicist François Arago, then Permanent Secretary, the journal Comptes Rendus de l''Académie des sciences allows researchers to quickly make their work known to the international scientific community. It is divided into seven titles covering the range of scientific research fields: Mathematics, Mechanics, Chemistry, Biology, Geoscience, Physics and Palevol. Each series is led by an editor-in-chief assisted by an editorial committee. Submitted articles are reviewed by two scientists with recognized competence in the field concerned. They can be notes, announcing significant new results, as well as review articles, allowing for a fine-tuning, or even proceedings of symposia and other thematic issues, under the direction of invited editors, French or foreign.
