| Abstract |
Heavy rare earth elements (HREEs) were tested for adverse effects to early life stages of the sea urchin Sphaerechinus granularis. Embryos were exposed to analytically measured HREE concentrations ranging from 10-7to 10-5 M. No significant developmental defect (DD) increases were observed in embryos exposed to 10-7 M HREEs, whereas 10-5 M HREEs resulted in significant DD increase up to 96% for HoCl3versus 14% in controls. Embryos exposed to 10-6 M HREEs showed the highest DD frequency in embryos exposed to 10-6 M DyCl3and HoCl3. Cytogenetic analysis of HREE-exposed embryos revealed a significant decrease in mitotic activity, with increased mitotic aberrations. When S. granularis sperm were exposed to HREEs, the offspring of sperm exposed to 10-5 M GdCl3and LuCl3showed significant DD increases. The results warrant investigations on HREEs in other test systems, and on REE-containing complex mixtures. |

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 02 March 2018.
All research outputs
#18,922,529
of 24,119,703 outputs
Outputs from Bulletin of Environmental Contamination and Toxicology
#2,738
of 4,112 outputs
Outputs of similar age
#246,036
of 335,045 outputs
Outputs of similar age from Bulletin of Environmental Contamination and Toxicology
#39
of 65 outputs
Altmetric has tracked 24,119,703 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% 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 29th percentile – i.e., 29% 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 335,045 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 65 others from the same source and published within six weeks on either side of this one. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
