| Abstract |
We studied heavy metal (HM) stress on wheat seedlings (AK-58) with and without coal fly ash (CFA) exposure. Three CFA spray rates were used to simulate air quality of the second level. Results show airborne particulates can directly enter plant leaves, affecting the whole plant. HM deposition decreases seedling size and mass and reduces activities of the chlorophyll family, photosynthesis enzymes (RuBP and PEPC), and photosynthesis efficiency. In leaves, HM deposition increases with the CFA spray rate. In roots, however, CFA exposure seems to reduce HM deposition, compared with the control without CFA exposure. A possible reason is that HM deposition in leaves from airborne particulates hinders photosynthesis, weakens the whole physiology of the seedlings, and consequently reduces root absorption of HMs from soil. CFA leads to chloroplast expansion, layer-stack disorder of grana, plastoglobule increase, and even chlorophyll membrane damage. |

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 09 April 2018.
All research outputs
#15,631,278
of 23,854,458 outputs
Outputs from Environmental Geochemistry and Health
#415
of 856 outputs
Outputs of similar age
#202,507
of 332,042 outputs
Outputs of similar age from Environmental Geochemistry and Health
#5
of 9 outputs
Altmetric has tracked 23,854,458 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 856 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 47th percentile – i.e., 47% 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 332,042 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
