| Abstract |
The present study aimed to investigate the effects of environmental heavy metals on sperm morphology and motility of Bufo raddei. We collected B. raddei from Baiyin (BY) and Liujiaxia (LJX); BY is an area heavily polluted by heavy metals, while LJX is a relatively unpolluted area. Significant accumulations of copper, zinc, lead and cadmium were observed in B. raddei from BY, together with relatively smaller sperm size and higher sperm abnormality rate. Unexpectedly, sperm velocity, percentages of sperm motility and viability of B. raddei from BY were significantly higher than those from LJX. Similarly, when sperm was suspended in heavy metal solutions, sperm velocity, percentages of sperm motility and viability significantly increased compared with those suspended in distilled water. These results indicate that environmental heavy metal stress may decrease sperm size, meanwhile enhance sperm motility through increasing the ratio of head length to total sperm length of B. raddei. |

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 01 August 2018.
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
#292,534
of 334,724 outputs
Outputs of similar age from Bulletin of Environmental Contamination and Toxicology
#20
of 55 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 334,724 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 55 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.
