概括

评估了Stenella attenuata (海豚) 中的微量元素含量. 虽然一般低,但高和的度表明局部污染,皮肤显示潜在的健康指标.

科学领域:

海洋哺乳动物健康
环境毒理学环境毒理学
生物监测生物监测

背景情况:

微量元素 (TE) 对于评估鱼健康至关重要.
关于被囚禁海豚的TEs及其组织分布的数据有限.
了解野生和养的海豚中的TEs可以了解饮食和息地影响,并改善护理.

研究的目的:

为了研究6个TEs (Hg,Cd,Cr,Se,Cu,Zn) 的度和组织分布,在野生和被养殖的Stenella attenuata中.
确定与TEs相关的潜在暴露途径和健康风险.
评价皮肤作为一种潜在的指标,对TEs积累在囚禁海豚.

主要方法:

在七种组织 (皮肤,肌肉,肝脏,脏,肺,脏,肠道) 中对六种TEs (Hg,Cd,Cr,Se,Cu,Zn) 的分析.
野生 (n=8) 和被囚禁 (n=6) 的TEs水平的比较Stenella attenuata.
对TEs的组织分布和相关性分析的评估.

主要成果:

大多数人表现出中等的TE水平 (Hg,Cd,Cr),具有较低的全球健康风险.
野生海豚的危险Hg (高达306μg/g) 和Cd (高达178μg/g) 表示局部污染.
摄入和吸入是TEs的主要暴露途径;皮肤与肝脏Hg和脏Cd有正相关性.

结论:

在Stenella attenuata中TEs的含量不同,有局部污染问题.
皮肤可能作为监测养海豚中TE的非侵入性指标.
消费的odontocete组织可能会造成人体健康风险,由于TE积累.

关键词:

囚禁中的odontocetes可以使用.禁止捕活动禁止捕活动奥登托塞特的健康状况微量元素中的微量元素.野生的Odontocetes可以使用.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...
