| Abstract |
Esfenvalerate is a neurotoxic pyrethroid insecticide widely used for agricultural and residential purposes and is considered toxic to nontarget organisms such as fish and aquatic invertebrates. In this study, we evaluated the toxicity of esfenvalerate on the aquatic oligochaete Lumbriculus variegatus. In the acute test, organisms showed visible signs of stress but no LC50 value could be determined. In the 28-day chronic test, a significant decrease in reproduction was observed with a NOEC value of 0.25 µg/kg and a LOEC value of 2.34 µg/kg. As for biomass per worm, a significant decrease was also observed with a NOEC value of 2.34 µg/kg and a LOEC value of 36.36 µg/kg. Reproductive impairment and reductions in biomass of L. variegatus exposed to environmentally realistic concentrations of esfenvalerate observed in laboratory tests suggests potential deleterious effects of this pyrethroid on oligochaete natural populations. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 21 March 2016.
All research outputs
#21,608,038
of 24,119,703 outputs
Outputs from Bulletin of Environmental Contamination and Toxicology
#3,090
of 4,112 outputs
Outputs of similar age
#339,367
of 399,000 outputs
Outputs of similar age from Bulletin of Environmental Contamination and Toxicology
#20
of 48 outputs
Altmetric has tracked 24,119,703 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,112 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 1st percentile – i.e., 1% 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 399,000 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 48 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
