Abstract

The authors quantified hepatic hydrocarbon-inducible cytochrome P4501A (CYP1A) expression, as ethoxyresorufin-O-deethylase (EROD) activity, in wintering harlequin ducks (Histrionicus histrionicus) captured in Prince William Sound, Alaska, during 2011, 2013, and 2014 (22 to 25 years following the 1989 Exxon Valdez oil spill). EROD activity was compared between birds from areas oiled by the spill and those from nearby unoiled areas. This work replicated studies conducted from 1998 to 2009 that demonstrated harlequin ducks using areas that were oiled in 1989 had elevated EROD activity, indicative of oil exposure, up to 2 decades post-spill. In the present study, the authors found that average EROD activity during March 2011 was significantly higher in wintering harlequin ducks captured in oiled areas relative to unoiled areas, which the authors interpret to indicate that harlequin ducks continued to be exposed to residual Exxon Valdez oil up to 22 years after the original spill. However, the 2011 results also indicated reductions in exposure relative to previous years. Average EROD activity in birds from oiled areas was approximately 2 times that in birds from unoiled areas in 2011, compared to observations from 2005 to 2009 in which EROD activity was 3 to 5 times higher in oiled areas. The authors also found that average EROD activity during March 2013 and March 2014 was not elevated in wintering harlequin ducks from oiled areas. The authors interpret these findings to indicate that exposure of harlequin ducks to residual Exxon Valdez oil abated within 24 years after the original spill. This work finalizes a timeline of exposure, extending over 2 decades, for a bird species thought to be particularly vulnerable to oil contamination in marine environments.

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 May 2017.
All research outputs
#6,909,595
of 11,549,448 outputs
Outputs from Environmental Toxicology & Chemistry
#1,987
of 3,126 outputs
Outputs of similar age
#132,103
of 254,863 outputs
Outputs of similar age from Environmental Toxicology & Chemistry
#42
of 82 outputs
Altmetric has tracked 11,549,448 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,126 research outputs from this source. They receive a mean Attention Score of 4.3. This one is in the 31st percentile – i.e., 31% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 254,863 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 82 others from the same source and published within six weeks on either side of this one. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
