| Abstract |
In Berlin, NH, the Androscoggin River flows adjacent to a former chlor-alkali facility that is a US EPA Superfund site and source of mercury (Hg) to the river. A study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic-level taxa in the river. Surface sediment directly adjacent to the source showed significantly elevated MeHg (10-40x increase, mean±sd: 20.1±24.8 ng g(-1) DW) and total mercury (THg, 10-30x increase, mean±sd: 2045±2669 ng g(-1) DW) compared to all other reaches, with sediment THg and MeHg from downstream reaches elevated (3-7x on average) relative to the reference (THg mean±sd: 33.5±9.33 ng g(-1) DW; MeHg mean±sd: 0.52±0.21 ng g(-1) DW). Water column THg concentrations adjacent to the point source for both particulate (0.23 ng L(-1) ) and dissolved (0.76 ng L(-1) ) fractions were 5-fold higher than at the reference sites, and 2-5-fold higher than downstream. Methylmercury production potential (MPP) of periphyton material was highest (2-9 ng g(-1) d(-1) DW) adjacent to the Superfund site; other reaches were close to or below reporting limits (0. 1 ng g(-1) d(-1) DW). Total Hg and MeHg bioaccumulation in fauna was variable across sites and taxa, with no clear spatial patterns downstream of the contamination source. Crayfish, mayflies and shiners showed a weak positive relationship with porewater MeHg concentration. This article is protected by copyright. All rights reserved. |

Attention Score in Context
This research output has an Altmetric Attention Score of 43. 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 05 May 2021.
All research outputs
#977,340
of 25,663,438 outputs
Outputs from Environmental Toxicology & Chemistry
#111
of 5,711 outputs
Outputs of similar age
#11,508
of 280,923 outputs
Outputs of similar age from Environmental Toxicology & Chemistry
#2
of 94 outputs
Altmetric has tracked 25,663,438 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 96th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,711 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.9. This one has done particularly well, scoring higher than 98% of its peers.
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 280,923 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 95% of its contemporaries.
We're also able to compare this research output to 94 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 97% of its contemporaries.
