Abstract

Polyacrylamide (PAM) has become an effective tool for reducing construction related suspended sediment and turbidity, which are considered to have significant adverse impacts on aquatic ecosystems and are a leading cause of the degradation of North American streams and rivers. However, little is known about the effects of PAM on many freshwater organisms, and prior to this study, no information existed on the toxicity of PAM compounds to native freshwater mussels (Family Unionidae), one of the most imperiled faunal groups globally. Following standard test guidelines, we exposed juveniles mussels (test duration 96 h) and glochidia larvae (test duration 24 h) to 5 different anionic PAM compounds and 1 non-ionic compound. Species tested included the Yellow Lampmussel (Lampsilis cariosa), an Atlantic Slope species that is listed as endangered in North Carolina, the Appalachian Elktoe (Alasmidonta raveneliana), a federally endangered Interior Basin species, and the Washboard (Megalonaias nervosa), a common Interior Basin species. We found that median lethal concentrations (LC50) of PAM ranged from 411.7 to > 1000 mg/L for glochidia and from 128.7 to > 1000 mg/L for juveniles. All LC50s were orders of magnitude greater (2-3) than concentrations typically recommended for turbidity control (1-5 mg/L), regardless of their molecular weight or charge density. Our results demonstrate that the PAM compounds tested were not acutely toxic to the mussel species and life stages tested, indicating minimal risk of short-term exposure from PAM applications in the environment. However, other potential uses of PAM in the environment (e.g., wastewater treatment, paper processing, mining, algae removal) and their chronic or sublethal effects remain uncertain and warrant additional investigation.

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 15 April 2017.
All research outputs
#4,668,428
of 9,692,018 outputs
Outputs from Environmental Toxicology & Chemistry
#1,672
of 2,945 outputs
Outputs of similar age
#117,175
of 263,697 outputs
Outputs of similar age from Environmental Toxicology & Chemistry
#20
of 72 outputs
Altmetric has tracked 9,692,018 research outputs across all sources so far. This one has received more attention than most of these and is in the 50th percentile.
So far Altmetric has tracked 2,945 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 42nd percentile – i.e., 42% 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 263,697 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 54% of its contemporaries.
We're also able to compare this research output to 72 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
