Abstract

Despite historical observations of potential microcystin-producing cyanobacteria (including Leptolyngbya, Phormidium, Pseudoanabaena, and Anabaena species) in 74% of headwater streams in Alabama, Georgia, South Carolina, and North Carolina during 1993-2011, fluvial cyanotoxin occurrence has not been systematically assessed in the southeastern United States (USA). To begin to address this data gap, a spatial reconnaissance of fluvial microcystins (MC) concentrations was conducted in 75 wadeable streams in the Piedmont region during June 2014. Microcystins were detected using ELISA (limit = 0.10 µg/L) in 39% of the streams with mean, median, and maximum detected concentrations of 0.29, 0.11, and 3.2 µg/L, respectively. Significant (α = 0.05) correlations were observed between June 2014 MC concentrations and stream flow, total nitrogen to total phosphorus ratio (TN:TP), and water temperature, but each explained 38% or less of the variability in fluvial MC across the region. Temporal MC variability was assessed monthly through October 2014 in five of the streams where MC was observed in June and in one reference location; MC was repeatedly detected in all but the reference stream. While MC concentrations in this study did not exceed World Health Organization recreational guidance thresholds, their widespread occurrence demonstrates the need for further investigation of possible in-stream environmental health effects as well as potential impacts on downstream lakes and reservoirs.

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 01 September 2016.
All research outputs
#13,290,477
of 21,321,365 outputs
Outputs from Environmental Toxicology & Chemistry
#3,508
of 5,253 outputs
Outputs of similar age
#191,822
of 374,431 outputs
Outputs of similar age from Environmental Toxicology & Chemistry
#30
of 77 outputs
Altmetric has tracked 21,321,365 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,253 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. 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 374,431 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 77 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 59% of its contemporaries.
