| Abstract |
Present investigation aimed to assess the alterations in branchial architecture of Ctenopharyngodon idellus exposed to chlorpyrifos. 96 h LC50 of chlorpyrifos to C. idellus was found to be 7.24 µg/L. Fish were exposed chronically to 2.41 and 1.44 µg/L sublethal concentrations (ecologically relevant concentrations) of chlorpyrifos for 15, 30 and 60 days. The gills of the CPF exposed fish showed partially affected secondary lamellae with shortening and curling, increased inter-lamellar space, sloughed off epithelium, hyperplasia and necrosis of pavement cells. On 60 days exposure, more pronounced degenerative changes, including severe necrosis, hyperplasia and hypertrophy of pavement cells, eroded and uplifted lamellar epithelium were noticed. Ultrastructural alterations include distorted nucleus and mitochondria in pavement cells, marked contraction in cisternae of golgi complex. Particularly in chloride cells, abundant mitochondria with distorted shape and size, dilation in between their cristae and tubular network were observed. The severity of damage was more profound at 60 days exposure. Thus, the observed cytopathological lesions of fish gills can be used as sensitive biomarkers for pesticide contamination. |

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 16 April 2018.
All research outputs
#19,611,252
of 24,119,703 outputs
Outputs from Bulletin of Environmental Contamination and Toxicology
#2,914
of 4,112 outputs
Outputs of similar age
#263,318
of 337,367 outputs
Outputs of similar age from Bulletin of Environmental Contamination and Toxicology
#35
of 61 outputs
Altmetric has tracked 24,119,703 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% 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 24th percentile – i.e., 24% 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 337,367 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 61 others from the same source and published within six weeks on either side of this one. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
